I currently have a Infinity Entra .5 setup consisting of 4 sat speakers a center channel and a 10" powered sub, ran off a HK AVR125. For movies the setup sounds pretty good, after a bunch of experimenting with the speaker locations. The problem is for music the highs sound good but lower end stuff seems to be lacking accuracy and it tends to sound boomy, or light on the bass since the little speakers handle the bass instead of the sub. The all the speakers at set to small right now. Would changing the fronts out for some towers to some thing like entra threes to voice match help at all? Or would waiting until I upgrade my amp in a while do more good, since I could pick some higher end stuff when I have more cash. I can't drop too much cash right now thanks to a almost dead water heater thats due to be replaced, as much as I like great sound being able to take a longer shower without freezing is important too LOL.
