Bass traps


What do they do? Specifically, will they help my anemic bass problem in the room? It's not the speakers.

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.
Instead of hit-and-miss, there are logical approaches to this which will maximimize the chance of success. Just throwing in panels and traps is not the way. Take a look at www.realtraps.com or www.rivesaudio.com for useful information. You do not have to buy their products to learn what sort of products you need for the problems you face.

BTW, I have experienced a significant improvement in the quantity and quality of the bass in one case where the listening position was in a null that was reduced by trapping at that frequency.

Does the bass sound different in various locations in the room?

The second step would be to get a Radio Shack SPL meter and a test tone CD or software and determine if there is any suckout at the listening position and elsewhere. The severity of the recourse depends on the the results. If the bass drops directly in front of the speakers, there's probably an equipment issue. Bass traps are not created equal and are designed for a frequency range.
Kal is of course right ("throwing in traps is not the way"), but I would just like to throw in that I tried something Jon Risch suggests along those lines. He mentions that you can buy a couple of bags of pink fibreglass and stick them in the corners behind the speakers if you want to know if a bass trap would change anything. I did that (you can imagine the WAF) and many things improved; not just bass, but also smoothness in the mids and imaging.

The pink bags are long gone, their contents in a wall somewhere, and an unfinished living room is still keeping me from installing anything better targeted to the space. However the memory of the improvement keeps me persuaded of the bass trap's viability. This particular measure was totally slapdash but boy, it worked well.
