Logitech Z-640 5.1 Speaker Surround Sound

Get the most from your computer games and DVD movies with Logitech’s Z-640 surround-sound speaker system. The system’s four satellites (left/right, front/surround) and center-channel speaker fill your room with sound, while the 25-watt powered subwoofer rounds out the bottom end to a deep 35 Hz, a good octave below the range of most bookshelf speakers, delivering floor-shaking bass from your music or a DVD’s low-frequency-effects channel, the “.1” in a Dolby Digital or DTS 5.1-channel presentation.

Inputs include a stereo analog (left/right) RCA pair and multi-channel analog inputs for decoded surround sound from any four- or six-channel sound card (or audio/video surround receiver).

The satellites are powered by 7.3 watts each, and the center channel, which handles up to 70 percent of most surround mixes, gets 16.3 watts. Logitech’s innovative, dual-chamber subwoofer delivers twice the bass energy of similarly sized subwoofers, and the company’s use of an internal power supply obviates the bulky wall adapters found on many surround systems.

All speakers are video shielded to allow distortion-free placement on or around your monitor, and the satellite speakers–imbued with easy-position rotating pedastals–may be mounted on stands, your desktop, or the wall. A handy supplied adapter ensures instant connectivity with gaming consoles.
