THX Certified Logitech Speaker System Z623 Ready to Rock the House

For big, bold sound from your music, movies and games, Logitech unveiled the THX Certified Logitech Speaker System Z623. With this 2.1 system, you'll hear and feel immersive audio from 200 Watts (RMS) of power whether you're connecting the speakers to a PC or a TV.

"Whether you're listening to rock music, watching a Steven Spielberg flick, or playing your favorite video game, the experience is always richer when you get engrossed in the audio," said Mark Schneider, vice president and general manager of Logitech's audio business unit. "That's why we built the Logitech Speaker System Z623 – so you can lose yourself in whatever you’re into. For DVD aficionados, music enthusiasts and hardcore gamers, the Z623 system delivers powerful audio for your room. And with THX certification, you know you’re getting the best."
So you can set up the system the way you want, Logitech includes all the inputs and cables you need to get great sound from up to three audio devices. With the RCA and 3.5 mm inputs, in addition to the built-in headphone jack, you can be set up in minutes to enjoy great sound from your computer, game console, digital music players, TV or DVD player. And to put you in command, the integrated controls on the right speaker satellite let you dial the volume and bass up or down to customize your listening experience.

Logitech and THX – Delivering Pure Performance
To get you totally immersed in your audio, the Logitech Z623 speakers are THX Certified and professionally engineered to recreate the tonal balance of whatever you're listening to. To qualify for THX certification, the two-satellite-and-subwoofer Z623 speaker system has to meet strict performance standards. Logitech engineers have worked closely with THX, conducting more than 400 acoustic and electrical bench tests covering frequency response, power output, distortion, noise and overall performance. For the Logitech Z623 speakers, the result is front speakers that deliver dialogue and ambient sounds so clear it's like you're on the set of your favorite film. And you'll hear powerful, deep bass from your subwoofer as it recreates the roar of a jet engine or the sound of a collapsing bridge.

Pricing and Availability
The Logitech Speaker System Z623 is expected to be available in the U.S. and Europe in September for a suggested retail price of $149.99 (U.S.).

I like the looks of these, I don't mind the SW + Satellite combo. My 4yr old + refurbished (and $30 shipped) Logitech X-230's still rock. Sure it takes some EQ to tune, but I'm not one of those guys that will spend 100's or 1,000's to look for the setup that doesn't need EQ-ing in speakers and headphones. I may keep an eye out for these in a year or two and see how prices are lookin'.

Find me 280watt RMS 5.1 setup that is THX certified (yes, it does mean something) for under 150 dollars shipped.

Also, what the hell does the enclosure material have to do with this? Sure, enclosures mean everything when you're talking about bass, but there is nothing wrong with "plastic" enclosures. As long as it is designed and tuned to the speakers characteristics, the enclosure material does not matter.

Rosewood is not going to sound better than MDF if both boxes are identical.

EDIT: Oh and THX is a sound studio. THX is a standard, and if a product doesn't perform they will not brand their name on it. Logitech isn't the best brand for sound but they aren't the worst, by far. Even a well known private company that does nothing but try to ensure good replication of audio for consumers is willing to put their name on it.
THX standards are low. That's why it's pointless.

There is a difference between plastic and wood in enclosures. Given identical designs, wood always sounds better. Plastic has a much different natural resonance than wood. This effects all drivers, whether bass or not. But, you are right that design is more important.

And this is only a 2.1 setup, not 5.1.

I have spent over $2,000 these last 2 years to build an impressive home theater experience, blowing over 250 Watts per channel (and as any audiophile knows, not everything is about watts, THD, sensitivity, etc... matters) on a 2.1 setup. And let me tell you, when you're listening to music or a movie with a lot of effects, you can tell the difference between a piece of plastic that costs $150 or a speaker crafted out of Rosewood at $900 a piece.
Your point about the Logitechs may be valid, but the rest is pointless in a thread about a setup that costs $130 bucks. Find me one comparable in cost that blows this out of the water instead of swinging your audio-peen around. :laugh:

I mentioned that because I got a z5300e setup with 280watts RMS, and the sound is amazing. I would prefer that the drivers have a separate tweeter but it still sounds superb. It definitely sounds better than the logitechs that don't have the THX badge.

If I were a reviewer I would definitely recommend these speakers.

I've heard a set of Klipshe with tweeters and awesome midrange speakers for the highs and dual 8inch subwoofers in a single enclosure firing opposed to each other, and it was probably the best computer setup I've ever heard, but the price difference is huge.

I just looked it up and found the speakers but they are discontinued, but look at it's specs man.

I wasn't even aware that they have a THX branding too, but it's funny that it does :)

It had the deepest bass and the cleanest highs, much better than my 5300e. I have never heard a 5500 in person but the sheer fact that the klipshe has dual 8's makes me skeptical if anything on the market aside from a custom setup could outperform it.

EDIT: Good lord Klipshe is an amazing company. http://www.google.com/products/catalog?rls=com.microsoft:en-us:IE-SearchBox&oe=&q=klipsch+5.1&um=1&ie=UTF-8&cid=16399750154157503957&ei=2y15TPVEhYKUB_m_kbQK&sa=X&oi=product_catalog_result&ct=result&resnum=4&ved=0CEQQ8wIwAw#p

No offense, but I think your speakers sound crappy too.

And they (and the Klipsch) would sound just as good without the THX cert. THX doesn't mean anything. You pay extra to get that badge, when all that really matters is the performance. These speakers were going to be designed that way, THX cert or not. It's just like SLI certification on PSUs, a marketing gimmick.

I just simply have never heard a Logitech setup that's worth the price.

And the HD Theater 1000's you linked are OK. Good for the price, but if you look, there is a 30Hz gap in the lower mid-bass. Probably sound a shitload better than Z5500s tho.

Crappy compared to what? They sound great to me. Crappy compared to the Klipshe.

But better than anything you'll hear in most electronics stores.

The only thing I don't like is that it can't replicate extremely low frequencies, like you would hear a 10, 12, or 15inch subwoofer produce. It also doesn't have seperate drivers for the extremely high notes. Music still sounds excellent, so do games and movies.

I would definitely say getting a decent sounding 280watt RMS 5.1 system for 130 bucks is worth the money.

You have extremely, extremely picky taste. I love the best things in life just as much as the next guy, but just because something isn't all exotic wood with the absolute most advanced amplifier technology on the market, pushing speakers made of some kind of polymer given to us by the gods themselves, which uses 0gauge cable wrapped around a car rim for a voice coil, doesn't mean it's not good or worth the money.

Your speakers probably use nasa material for a stabilization spider, and hummer tires for the surround.

The earth as a magnet.

280w RMS is meaningless when they can only put out 100w of that cleanly. The average human can hear THD above .5%, sensitive people can hear as low as .1%. At 280W, the 5300e's have a mind boggling 10% THD. They sound like crap, even compared to the 5 year old Altec Lansing setup my Mrs has, that cost half as much. Not to mention, the 5300's have an even bigger hole in frequency response to the Klipsch speakers you posted.

Sorry, but they are not good sounding.

And no, I actually just have bottom of the line polk speakers and an Onkyo receiver for my home theater, and just use a Panasonic SC-PM39D 2.0 channel shelf system for my computer for now, until I upgrade the home theater and take the polks. There are much better sounding setups than mine, just not anything from Logitech.
