Review: Altec Lansing Expressionist PLUS FX3021







Source: Chapree (Lowyat.net)

The world famous Altec Lansing needs no introduction. Being a company with long history, majority of us had probably comes across their products at least once in our lifetime.

After being acquired by Plantronics in 2005, Altec Lansing undertook a huge corporate makeover. As a result, the company adapted a new logo and released a number of newly designed speakers to highlight their new image. One of the said speakers lineup is called the Expressionist.

The Altec Lansing Expressionist PLUS FX3021 is the latest model in the series, which includes the Expressionist BASS FX3022 that we reviewed earlier and a more back to basics, Classic FX2020. Check out how the new model performs, after the jump.


The FX3021 comes with 2 satellite speakers and 1 subwoofer, making it a traditional 2.1 configuration. Both the speakers and subwoofer are triangular shaped, similar to UFOs. The satellite speakers are mounted on a movable frame that acts as their base, together with three movable rubber feet. Five permanent rubber feet are also spotted underneath the subwoofer

Subwoofer control is located on top of the subwoofer and also acts as the power button. The volume controls and power indicator are conveniently placed on top of the right satellite speakers. No actual treble control is available though.


FEATURES

According to Altec Lansing, inside each satellite speakers is a 2" 4 Watts full-range drivers while the subwoofer contains a 5.25" 28 Watts woofer which altogether has total continuous power of 33 Watts RMS. Altec also incorporated down-firing, long-throw design as FX3021's subwoofer projection path.

Apart from the normal stereo input port, the FX3021 has one extra auxiliary input port. Both of these ports are located at the back of the subwoofer, together with satellite speaker and power adaptor port.

SOUND TEST

To test the FX3021, we plugged it to our AMD test rig that we used to review a graphic card previously. The machine is equipped with Realtek ALC889A audio codec that is built into the rig's Gigabyte GA-MA790GP-DS4H motherboard. We believe that this setup should be able to represent common application of the speaker as majority of PCs these days’ runs on built-in sound processors.

As for external media player, we use first generation Apple iPod Touch with EQ set to "OFF" and without any external audio amplifier application. We also flatten out our EQ settings on our software players which are Windows Media Player 11 and foobar2000. We also maxed out the volume level on our test rig, iPod and software players.


We run through the speaker with a lot of audio tracks across several genres from classical to electronica. Some of these tracks are in MP3 format while some are played from audio CDs. We also didn't forget to run couple of games and movie DVDs since both of them are also typical usage of a speaker.

Overall, the output from FX3021 is pretty balanced. Even with the subwoofer maxed out, the treble output is generally quite level with the bass output from the woofer. Not only that, the subwoofer is quite powerful and able to shake our table with its thumping bass output when the volume level is loud enough. That being said, we found out that we need to increase the volume a little bit higher when it comes to treble-heavy audio tracks such as classical, jazz and acoustic tracks regardless whether the tracks are being played from PC, MP3 player or CD.

Traditionally, a subwoofer is placed on the floor but we found out that FX3021's subwoofer performance is not as good as when it is placed on desktop. Hence, the "Desktop Subwoofer" label on its retail box. Potential owners of this speaker might want to consider clearing some space on their desktop for the subwoofer then.



CONCLUSION

In terms of looks, the FX3021 have a very huge aesthetic value due to its unique design. Not only it is stylish but it functions very well as a compact and powerful 2.1 sound system. But then, for it to perform optimally, the speakers need to be placed on the desktop itself.

Did we mention that FX3021 is priced just under RM 400?

Pro:
Affordable price, bass/subwoofer control knob, overall sound output is very powerful, adjustable speaker angle, dual input port, sleek and stylish design.

Cons:
No treble control, no headphone output, need to crank higher for classical music, subwoofer less performing when placed on the floor hence need some space on desktop.

Hackers expose weakness in visiting trusted sites

Source: The Star Online

LAS VEGAS (AP): A powerful new type of Internet attack works like a telephone tap, but it operates between computers and Web sites they trust.
Hackers at the Black Hat and DefCon security conferences have revealed a serious flaw in the way Web browsers weed out untrustworthy sites and block anybody from seeing them. If a criminal infiltrates a network, he can set up a secret eavesdropping post and capture credit card numbers, passwords and other sensitive data flowing between computers on that network and sites their browsers have deemed safe.


In an even more nefarious plot, an attacker could hijack the auto-update feature on a victim's computer, and trick it into automatically installing malware pulled in from a hacker's Web site. The computer would think it's an update coming from the software manufacturer.
The attack was demonstrated by three hackers. Independent security researcher Moxie Marlinspike presented alone, while Dan Kaminsky, with Seattle-based security consultancy IOActive Inc., and security and privacy researcher Len Sassaman presented together.

They reached essentially the same conclusion: There are major problems in the way browsers interact with Secure Sockets Layer (SSL) certificates, which is a common technology used on banking, e-commerce and other sites handling sensitive data.

Browser makers and the companies that sell SSL certificates are working on a fix.
Microsoft Corp., whose Internet Explorer browser is the world's most popular, said it was investigating the issue. Mozilla Corp., which makes the No. 2 Firefox browser, said most of the problems being addressed were fixed in the latest version of its browser, and that the rest will be fixed in an update coming this week.

VeriSign Inc., one of the biggest SSL certificate companies, maintains that its certificates aren't vulnerable.

Tim Callan, a product marketing executive in VeriSign's SSL business unit, added that the "tap" won't work against so-called Extended Validation SSL certificates, which cost more and involve a deeper inspection of a company's application for a certificate.

The attack falls into a class of hacks known as "man-in-the-middle," in which a criminal plants himself between a victim's computer and a legitimate Web site and steals data as it moves back and forth.

Jeff Moss, founder of the Black Hat and Defcon conferences who this summer was appointed to the Homeland Security Department's advisory council, said the fact a hacker has to actually break into a victim's network for the attack to work can limit its usefulness.

"That's the nice mitigating thing," he said. But he warned that "for targeted attacks it's absolutely deadly. This is the way you can get everything. If you can get in the middle, you can get everything. It's a big, giant wake-up call for the industry."

SSL certificates are a critical technology in assigning trust on the Web.
Sites buy them to encrypt traffic and assure visitors it's OK to enter confidential information. Companies that sell SSL certificates verify that someone trying to buy a certificate actually owns the site that certificate will be attached to.
The presence of an SSL certificate on a site is designated by a padlock in the address bar. But many people don't pay attention to whether a padlock is present or not.

Browsers do care, though, which is why this week's talks were significant.
Browsers are programmed to block sites that don't have a valid SSL certificate, or have a certificate displaying a Web address that doesn't match the address a Web surfer was trying to reach (which can indicate someone has hijacked a person's Internet session).

If the sites aren't blocked, users are warned about potential danger, and have the option to click through.
The problems outlined by researchers center on a quirk in the way browsers read SSL certificates.

Many SSL certificate companies will allow people to attach a programming symbol called a "null character" into the Web address onto the certificates they receive.

Web browsers generally ignore that symbol. They stop reading at that symbol when they're checking the Web address on a certificate.
The trick in the latest type of attack is that all a criminal would need to do is put the name of a legitimate Web site before that character, and the browser will believe that the site it's visiting - which is under the criminal's control - is legitimate.

The criminal could then forward the traffic onto the legitimate site and spy on everything the victim does on that site.
It's a complicated attack, but it highlights a significant weakness in the very technology widely used to assure people it's safe to navigate sensitive sites.
Jon Miller, an SSL expert and director of Accuvant Labs, said he expects significant attacks against corporations using this technique in the coming months. Criminals who run "phishing" scams, in which people are tricked into visiting phony sites, will also likely latch on.

"What kind of makes this earth-shattering is these aren't the most sophisticated attacks in the world," he said. "This is going to become a huge problem."
There are signs it's already starting. VeriSign's Callan said within hours of the talks, his company got a number of applications for SSL certificates featuring null characters, but they were denied.

Samsung 8500 Series Local-Dimming LED TVs Have a Sweet Base


Source: Matt Buchanan, (Gizmodo)





Yeah, the 8500 series is Samsung's first set of LED-backlit LCDs with local dimming this year and has the Yahoo widget engine for streaming video, but all I really care about is that awesome looking blue stick holding it up.
I mean just look at it. It's from the future or something .
The obviously 1080p set is using white LEDs, along with local dimming, unlike say, Sony's which use tri-color LEDs for better color. You can cue up the usual so-great-they're-meaningless measurements you get with LEDs though: 7,000,000: 1 contrast ratio, 2ms, Auto Motion Plus frame interpolation, and an Ultra Clear Panel that "works to improve image clarity and brightness regardless of a room's ambient lighting." But it is only 1.6 inches thick.
There are two models, the 46-inch class (45.9 inches) set for $3600, and the 55-inch class (54.6 inches) for $4500, both out in September.

The Internet@TV - Content Service, developed in association with Yahoo!, provides onscreen access to popular web-based content from Yahoo! (Flickr, Video, News, Weather, and Finance), USA Today (Sports), Twitter, YouTube, and others. The widgets-based interface and scrollbar are activated with the push of a button, and run along the bottom of the screen for easy browsing of the latest programs and content available.

Even after purchase, consumers will be able to use a growing library of widgets, as the widget development kit is available for other content providers to develop new offerings. Samsung's Medi@2.0ä suite provides wired and wireless DLNA compatibility to enjoy photos, music and videos from a networked PC right on the television. Pre-loaded photos, artwork, games, and recipes are also included for entertaining, and two USB 2.0 connections can be used for playing a plethora of video, photo, and audio files from portable devices, including external hard memory.
Designed to Stand OutMeasuring at just 1.6 inches deep and featuring Samsung's Touch of Color™ (ToC™) bezel, the 8500 Series provides consumers with style and flexibility in an HDTV. Additionally, both the 46-inch and 55-inch models come with a built-in tuner and an array of multimedia connections. Samsung's innovative, ultra-slim wall-mount solution (sold separately) makes installation akin to hanging a picture frame, by reducing the gap between the TV and the wall to a mere 0.6 inches – a major improvement over traditional mounting systems.

First LG Chocolate BL40 Official Shots Don't Surprise, Still Stun


Short of price, release date and carrier(s), there's not a whole lot that hasn't been leaked about LG's comically long next generation Chocolate, the BL40. But somehow, these first official shots are still enticing. I mean, look at it.




Shock and mystery, I suppose, are at the core of the BL40's appeal, at least until someone actually gets to try one. For everything we do know, and can see reconfirmed here—the featurephone OS, the 5-megapixel camera, the 21:9 screen, the forward-facing videocalling sensor—there's a less tangible thing that we don't: How does it feel in your pocket? Your hand? How well does browsing work? How does this phone deal with video that's not encoded for silly-wide display? And until we find out that LG hasn't discovered clever and/or magical solutions to these potential issues, ogling is the order of the day.

Sony X-Series Walkman Review: Why, Sony? Why?



The Sony Walkman X-series is Sony's premium flash-based portable media player, packing Wi-Fi, noise-cancellation, a redesigned UI and a gorgeous OLED touchscreen. But can it compete with the reigning champ, the iPod Touch? In a word, no.
That's not to say it isn't an impressive player in its own right. It handily beats the Samsung P3 and the Cowon S9, but I'm left wondering who would pick this up instead of a Touch. But if Sony were to stick this UI into one of their Sony Ericsson Walkman musicphones, they might have something powerful indeed.

Physical
The X-series is a very sleek player, similar in size to the Samsung P3 and significantly narrower and shorter than the iPod Touch, though ever so slightly thicker. It's designed with an unusual aesthetic: The sides of the player are this odd sort of rough, glittery metal, similar to unfinished granite, and the back and front bezel are black glass with little shiny sparkles in them, like a granite countertop. It's a nice-looking player, certainly, and it feels very solid in the hand. I just don't totally get the granite thing—it's not spectacularly eye-catching.



On the front of the X-series is the screen, an unbelievably responsive 3-inch OLED capacitive touchscreen, and a large "Home" button underneath the screen, much like the iPod Touch. The screen is crystal clear, the sharpest picture I've ever seen on a PMP—it lives up to the promise of OLED. Viewing angles are limitless, and touch response is great, without any lag at all. Unfortunately, that glass front and back are awful fingerprint magnets, though being glass, it does seem to resist scratching fairly well.

The right side hosts the noise cancellation switch and a surprisingly cheap-feeling volume rocker. The top has the headphone jack and the pleasantly firm play/pause, track forward and back buttons, while the bottom edge is home to the proprietary USB jack. Interestingly, the hold button is a giant semicircle switch on the back of the player—it seems weird, but I actually love how easy it is to reach and how solid it feels. The numerous hardware buttons make it a very nice player to control in the pocket, despite mostly being touch-based player.

The X-series is one of the only PMPs with built-in noise canceling, but it only works with the included earbuds. Fortunately, said earbuds are excellent for freebies, and the noise cancellation worked perfectly on my noisy Chinatown bus ride between Philly and New York City. Noise canceling does slaughter the battery life, though, draining it twice as fast as regular playback. When you're trying to drown out the kind of crazies who take the Chinatown bus, you'll be glad it's there.

Audio quality is a hallmark of Sony's PMP line, and the X-series does, in fact, sound great. It includes a customizable five-band equalizer for audio dorks and some nice sound enhancers like DSEE. On the other hand, you're limited to the lossy codecs Sony supports (MP3, WMA, WMA-DRM, AAC), so it may not be a good choice for serious audiophiles.

User Interface

The home screen has a familiar grid of icons, including Music, Movies, Photos, Podcasts and some more intriguing Wi-Fi-based apps like Slacker, YouTube and Browser. Navigating through lists of artists, songs and albums is very similar to the iPod Touch style with a grab-and-flick interface, though a fast flick leads the list to cycle through a lot faster than the touch, almost like there's less virtual friction, and we'd say it feels just a hair less exact.
At the bottom of the Now Playing screen, there are four icons I've decided to term Back, Navigate, Web, and Options. The icons themselves aren't very literal: The Back icon is a bulleted list, and Navigate is a magnifying glass, so it's slightly confusing at first. But once you touch it, it becomes very clear what each button does, and I had no problems after that.
The "Navigate" button is great: It'll bring up a list containing Artist, Album, Songs, etc that'll let you jump right to that list without having to hit the Back button four times. The iPod Touch doesn't have anything like it, and now I wish it does. The Web button is also really cool: It brings up a screen that'll let you search the track name, artist, or album with Yahoo or YouTube. The Yahoo search brings up hits like Wikipedia and AllMusic, and the YouTube search immediately brings up a ton of music videos, live concert footage and more to watch on the player. Pretty cool stuff. Oddly, the X-series will prompt you to re-connect to a wireless signal every time you try to do one of these searches, and though it remembers your password, it's still annoying.
The X-series also includes an FM radio, and it's worth mentioning because it's one of the stronger FM tuners we've seen in a PMP. It's not like it'll change the way you think about radio, but it does as good a job as you could ask.

Web Apps

The YouTube app is really great, quite similar to that of the iPod touch or iPhone except with a classy sheer black skin to match the X-series' aesthetic. Videos load quickly and are very clear and watchable, provided you've got a solid Wi-Fi connection.
Slacker is another hit for the X-series, giving access to either the free or paid versions of the Pandora-like service with the same skin as the rest of the UI. It's super fast to load and sound quality is excellent.

Unfortunately, Sony's only two for three on the web app front, and the most exciting of its new features is a major fail: Its internet browser—NetFront-based, like PSP and Sony Ericsson—is completely unusable garbage. All text entry is done via an infuriating T9 interface (why not just rotate to a landscape QWERTY? There's plenty of room!) that's inexact and totally unhelpful. It requires you to type in "http://www." before every URL. Even if you've got the patience to sit there for ten minutes to type "http://www.gizmodo.com/", the browser can only manage those dinky mobile sites without totally freaking out. Browsing full sites is an exercise in futility, as the two zoom buttons don't always work, you can't navigate before a site has fully loaded and tapping links is inexact and frustrating. Basically, it's worthless as a web browser, which is a huge disappointment. This image pretty much sums up the X-series web browsing experience



Desktop Software

The X-series has both a MTP (Windows-only) and a UMS (shows up as a drive, compatible with Mac and Linux as well), though UMS must be switched on before each connection. That means it'll work with most any media player, save iTunes. Sony's "Media Manager" software is included, but it's pretty awful, very archaic and difficult to use, and won't convert video unless you pay for the "Pro" upgrade. That last part is a real killer for the X-series' video capabilities.
Speaking of video conversion, you'll be doing a lot of it, since the X-series only supports a few video codecs and none of the common pirate formats (Matroska, XviD) are included, unlike the pirate-friendly Samsung P3. I used Cucusoft and was able to get a few MPEG-4 videos onto the player, but your average user will definitely have trouble figuring it out. None of the WMVs I tried would work, and I never was able to get a great-quality video on to test out what the OLED screen can really do. iSquint for Mac does work, but the quality, while totally watchable, is disappointing: On an OLED screen like this, you want to be blown away by video quality, and I wasn't.

Audio codec support is disappointing too, considering the X-series' stellar audio performance: The only lossless format is WAV, which nobody will use due to its massive file size. Besides the preferred lossless formats, more niche codecs like OGG aren't supported either. The player has incredible capabilities, yet Sony cripples it by limiting its compatibility—they could have courted the audiophile market, but 320kbps mp3 files can only sound so good.



Price and Conclusion

The X-series, according to Sony, is a premium gadget and thus commands premium prices—coincidentally the same prices as the iPod Touch. The 16GB version costs $300, with the 32GB going for $400. The difference is that the iPod Touch comes with a massive App Store for boatloads of new features, not to mention an accelerometer, a web browser that won't make you long for the days of WAP, tons of accessories, and software that actually works. The X-series just can't compete with that.

The X-series is a really solid player: The form factor is nice, the screen is incredible, sound and video quality are as high as these things get, and it comes with built-in noise canceling. If it were $50 cheaper, I'd have no hesitation about recommending it over the Samsung P3 and Cowon S9, but if you're spending at that level, you'd be buying the wrong machine if you chose the Sony.
On the other hand, we do see a successful future if Sony put a phone version of this up against Nokia's XpressMusic. It could never be a smartphone, not in this shape, but it could be a great music-based dumphone.

Sony understands that PMPs can't just be PMPs anymore: basic iPods aren't selling like they used to, and the Touch is part of a mobile computing platform. But to just stuff in some Wi-Fi features without thinking about software expandability or even a usable browser—that's not going to cut it these days. Sadly, despite all the things the X-series does right, it's emblematic of Sony's current slide into muddled mediocrity.
