I'd agree that there could be more bass but the highs are alright. I don't think the subwoofer was designed for thumping bass, but rather complimentary to existing bass. The best sound comes from CDs and of course the DVD audio or 5.1 audio CDs. Put those in and mids and highs come alive. The 5.1 sound is great.

 

I'd agree. My wife & I have the 05 TL w/ Nav. in automatic. We test drove the TSX & had the loaner TSX when we had our TL in shop something small.The TL doesn't hit no where near as hard as the TSX does, especially since the TL is a better car than the TSX. I love the car overall, but Acura should've put the TSX system in the TL & vice versa.
