I just recently brought the Z623 THX 2.1 system. I have a Mac, but my brother (who got the same system, but uses a computer) he gets a much more strong bass that shakes the entire house. my bass just seams week compared to his. is there a subwoofer tuner og a way to adjust the bass?
This might help
Also be aware that the sound of the subwoofer is very dependent on its position so it will sound different in a different room even if everything else is identical.
