Logitech Z625 Reviews

Best sound and features at a reasonable price.

Sounds great! I particularly like the input flexibility, the Aux input and headphone jack on the right satellite, the power button on the satellite (listening Klipsch?), the reliable feel of the volume and bass controls also on the satellite, and THX certification. Reasonably priced, too. TU B&H Photo!

I noticed there is no button to change/switch the input source. If I connect 2 computers to the inputs how I choose which computer to listen? Or, both computers are being played on the speakers at the same time?

Is the subwoofer wired or wireless? Thank you and God bless!
Asked by: Charles K
Hello Charles. The Z625 has a wired subwoofer. The sub actually houses the amplifier, so it connects to the computer and then distributes the signal to the satellite speakers.
