Bass traps

Speaker, speaker placement, cables, and your other equipment will determine the amount of bass produced.
Each is equally important.

Bass traps control bass boom and help define the tone and soundstage.

I am doubtful they can ever make a huge difference in the bass...an improvement certainly but I doubt you can turn anemic bass to strong bass response. They should smooth things out a little above 100 Hz in the frequency response ....but most of the benefit will be in reducing reverberation...i.e. cleaning things up...adding clarity when bass notes are close together.

I am waiting on my traps to arrive...so my comments is based on what I have read.

The room that I have is just too bright and I'm toning it down with Sonex panels. I'm thinking that by adding a couple of 4' corner bass traps it'll focus the bass more. It's not the speakers, wires, amps or the rest.
