Product Description

From the Manufacturer

Logitech Z-5500 5.1 Speaker System
Intensify your entertainment with true cinematic surround sound

Hear your movies, music and games the way the studio meant them to be heard—in true THX-certified digital surround sound. From the pitter-patter of rain in your favorite movie to the ground-shaking explosion in your favorite game, this speaker system totally immerses you in a theater-style surround sound experience. You've also got all the power—505 watts of it—to make soundtracks come alive in thunderously rich distortion-free detail. If you want to take your home entertainment to a whole new sound level, this is the one.

Key Features

THX-certified theater-quality audio
Only a select few PC speaker systems have earned the THX seal of approval. THX certification is your absolute assurance that these speakers accurately recreate the sonic experience of a movie theater.

Immersive Dolby digital and DTS 5.1 surround sound
Experience the full-resolution digital surround sound the studio intended. Featuring both Dolby Digital and DTS decoding, the Z-5500 speaker system puts you in the middle of the action with true 5.1 surround sound. The system even incorporates Dolby Pro Logic II, transforming your favorite old 2-channel stereo movies, music and games into realistic 5.1 surround sound.

Phase Plug drivers reproduce every little detail
From the soaring high note in a guitar solo to the loud burst of jet engines in an action movie, Logitech Phase Plug drivers make sure you don't miss a sound. A cone-shaped aluminum Phase Plug at the center of the driver helps to accurately reproduce high- and mid-range frequencies with less coloration than standard drivers. And because the Phase Plug acts as a heat sink, the driver is better able to preserve dynamic range. So you hear the quiet of a whisper and the loud, full force of an explosion. The Phase Plug even acts as a reflector, creating a much wider sweet spot of mid to high frequencies compared to conventional speaker designs. The bottom line? The true sonic signature of your movies, music and games comes through loud and clear.

505 watts of powerful performance
You've got more than enough power to surround yourself with thunderous audio clarity. No need to hold back. Crank up the volume—way up. The high-performance speakers can handle the volume, so you hear every note, voice and sound effect without a hiss or crackle. All that power also comes with integrated digital equalization. Sit back and the system intelligently adjusts frequency response in real-time for cleaner, more accurate and balanced sound.

Long-throw subwoofer for deeper bass
The Z-5500's powerful 10-inch, 188 watt subwoofer reproduces low frequencies at their deep, room-shaking best. The long-throw design effortlessly delivers distortion-free bass so full you can feel the rumbles and booms that make movies and games more exciting. And with Logitech's flared side port, the port noise that can occur with conventional subwoofers is eliminated. So you can enjoy those thick, thumping bass notes without distractions.

Versatile satellite speakers
You have the options to customize your setup. The cloth grilles can be removed to give your system that pro audio look. And the rotating pedestals made it a cinch to either place the speakers on a desk or mount them to the wall.

Audio inputs for multiple components
Enjoy pro-quality surround sound from virtually any digital or analog source. Plug in up to six devices simultaneously—PC, iPod, DVD player, game console and more—and leave them there. With one optical, one coax digital and four stereo inputs, there's plenty of room to connect your gear.

Convenient digital control center and wireless remote
The Digital SoundTouch™ Control Center lets you easily change volume, audio sources, surround sound settings and even mute the system. A separate remote gives you audio control of up to seven different sound sources, from your PC to the game console.

    These speakers are even better than I read about. The main thing that nobody seems to mention is that these speakers basically have a built-in receiver so you can plug your DVD player or whatever directly into the speakers. This, imo, is so important that all the other competing speaker systems really don't compete. Obviously, it's not as good as having a real receiver and can't amplify as much as an external system, but most people that want to hook these speakers up to their computer and other devices simultaneously, and would like to save space and money, would really appreciate this. The toslink output is the highest quality I've heard. Also, I made the mistake that others have made of removing the screw on the back of one of the speakers, rendering it impossible to put the stand back on. And if you open it to fix the problem, you'll void your warranty, so I have to send it to Logitech to be replaced. So, if you need to put these on a stand, whatever you do don't remove any screws on the speaker.

    Wow. Wow. Wow. Wow. Oh and Did I mention WOW ?

    I have three cables for 5.1 going from my sound card into the box. I have the digital out going from the soundcard, into the logitech for 5.1 dvd movies through my computer. As well i have fiber optic coming out of my sattelite into the setup box so i can listen to 5.1 while watching tv. Maybe not 5.1 but emulate pro logic it sounds great. So im definetly making use of all the inputs on the back of this baby.

    This has a lot of features, and different modes you can use. It has Stereo (which is just front l/r speakers outputting sound), Stereo 2(front left/right, rear left/right), Pro logic II Movie (i dunno? Uses the center channel, less of the rears more of the sub, pro logic Music (heavy on the sub, uses all speakers). As well it's easy to scroll through the inputs Coax, Direct 6channel, optical.

    The remote it comes with is pretty useful you can adjust volume, sub levels, surround output (dont know what this does yet). It is wicked fun!

    I paid $270 shipped from Amazon (forget ripoff COMPUSA), got it in TWO Days. I love audio always have, always will. This was a 5.1 for my computer, but I also wanted 5.1 for movies that I watch in my room.

    This comes with cables for analog games which is how games output. However I bought a coaxial for digital out for games, and a fiber optic cable for my sattelite to the box. Total cost through circuit city $70. Total cost through amazon $30. Shop amazon! :)

    Initial impression


    Lets just say setup wasen't easy. It is pretty standard, connect one speaker, another speaker, another speaker. it just takes a while to light up everything connect everything.

    After getting the MX1000 laser mouse and the Z-5500 speakers i fell in love with logitech. These speakers produce quality sound, they sound better than the Z-680 my friend has. I have SB Audigy 2zs platinum with front panel and an optical output. I am using Monster THX certified optical cable bought from amazon for $22 and my system rocks. the sound on my computer cost me $470 but it is worth it. Thank you amazon! they shipped it the same day, ordered on Monday and got it on Wednesday. I ordered it when the price was $306.99 then the price dropped to $279.95. I love Amazon, they refunded the difference after I emailed them. The speakers sound VERY clear, no hissing as with the Z-680 and an RCA cable. the subwoofer is huge and you need to have a space for it and it has a strong magnet so you need to keep it at a reasonable distance from your computer and monitor. The speakers cable are not adjustable, but i am guessing you can buy an extension cable if you need to, but the cable is fairly long. the Base of the speakers is adjustable so it fits on the table and on the walls.

    I am very impressed with these speakers. I have not yet gotten a digital connection, but I can't wait. The sub is quite powerful, but not as big as so many people mention. I have a little hiss from my front right satellite, but I think I can fix that. I got the speakers refurbished, so that is why they're like that. The controller is very nice to have and I use it all the time, and I'm in a small room. I just like to be adjusting the volume wherever I am. Like others have said, the midrange is a little lacking, but its so small of a problem that it doesn't matter, unless your an audiophile. It would bother you then. The control box is very nice and has quite a bit of good functions. You can select input, the effect of the audio, the settings for the input, the volume level of the Sub, Center speaker, and back two surround speakers, mute, adjust the master volume, and Turn the whole system to standby. Also it can go very loud. I keep my computer volume all the way turned up so I only listen to the speakers turned up about 4 bars. There are 20 total bars and 11 boost bars. I don't know if the speakers can take going that loud, but I know that my ears can't. I don't like listening to music very super loud, but I know that I can anytime I want.

    The Subwoofer.
    The sub is a ten inch long throw woofer. Looking straight at the woofer, Its 13 inches tall, 13 inches wide, and 18 inches back (including the cooling fins and speaker grill). The cooling fins must be 6 inches away from anything (according to the manual). They are 1.5 inches long, 9 inches tall, and 8 inches wide. There are the five wire connectors for the speakers which are labeled for easy assembly.
