Hello
It
Get RAL and RTZ program for your PC and a mic, run the pink noise and look at the RTA below 300hz. Then set up your system to make it look the best you can. Then buy a parametric DSP like a Behringer 2496 and tweek the bumps. (Nulls really aren't tweekable this way) This has worked extremely well for me in 3 different rooms. Only a sweet spot tweek and it doesn't deal with reverberation but it's very effective and cheap.
This is the first thread I have found that talked about room treatments. I am moving into a apartment. The walls are thick plaster and I shouldn't disturb my neighbors. I don't listen at the same intenisty I used to.
The room is really long and I can't set the stereo up in a symetrical way.
I was wondering if Echobustes/bass busters would help enough to justify the big bucks.
You are complaining about lack of bass and then want to apply bass traps. Bass traps are designed to absorb low frequency energy. They will not provide more bass.
Changing speaker position and listening position will change frequency response greatly.
The idea about making room measurements and then comparing different setups is the way to go.
I would like to try and keep the bass in my apartment and not share it with the neighbors. So maybe BassBusters are the way to go.
They can. If they absorb bass frequencies in the corners, they can moderate the resultant nulls as well as the peaks.

Kal nailed it. All acoustic problems are caused by reflections off the walls, floor, and ceiling. The only difference between a reflection that causes a peak and one that causes a null is the phase as relates to frequency and distance. If the reflection arrives more or less out of phase the result is a null. And good bass traps absolutely improve nulls!
However, they do nothing to reduce the amount of bass escaping from the room. That requires construction - new walls, floating floors, and so forth.

Kal,
Your articles every other issue is the first place I turn to. Even though classical is only makes up 10% of my collection.
This answers my question.
I'll have to see how much money is left after the dust settles and invest in some "busters"
So how did you make out? Did you end up purchasing the new cones?
Hello Everybody
Last year I went to an audio show and in the end I realise that my sound was worst than some presented in the show with lower equipment. The problem I have was clarity and resonance at low frequencies. The room is small (4.0 m x 4.5 m and one 2x2m corner) and low frequency resonance and interference was destroying the quality of the equipment. But, has must of you know, after a while we get used to the sound, we only listen selected music, etc, and, if we don't have a reference, we forget the problem and the money that we think need to solve it. This time I was awaked by the show and after some research in the Web I constructed some bass traps for the corners of my music room (see Gallery, Harvex), without destroying the room and with only 500
