Three problems no amplifier will fix

I spent years answering three problems with equipment. Comb filtering from reflections, massive bass peaks and nulls from standing waves, a soundstage smeared by early reflections. Not one of them lives inside a box on the rack.

They live in the walls, the corners and the distance between your seat and the back wall. My own seat was very close to the back wall, which made the first reflection points the biggest problem I had. A new amplifier plays into exactly the same room as the old one.

Finding them costs nothing. Clap your hands at the listening seat: is there any echo coming back? When you sit with your friends, is it difficult to follow them? These are very basic answers, but they tell you whether your room has an acoustic problem before you spend a cent.

Then fix them in the order they cost. Position the speakers first, which is free, then up to $500 on first-reflection panels, then a similar amount on bass traps in the corners. I strongly suspect your low end will come out tighter than any subwoofer integration someone recommends to you.

Your amplifier cannot hear your walls. Your hands can.
