Echo Buster "Corner Busters"

Hi guys
If you remember,a few months ago i mentioned i had a problem
with room acoustics.Specifically,bass problem,or lack of it.
After re-arranging furnitures and repositioning of loudspeakers,the result was some bass when seated and lots of when standing.I knew i needed some bass traps but those items are expensive and bulky and together with transportation costs,prohibitive.Anyway,two weeks ago,i places an order for some lps and decided to purchase 4 corner busters in the hope that they would do something to the sound.Better something than nothing lol My room has a peculiarity.Six corners instead of four but i could only purchase them in fours.One of the corner is the doorway and when the door opens,you can't have a corner buster there,so,
i decided to get just four and leave one corner untreated.
Anyway,i knew that 3 particular corners HAD to be treated and so i did,and left two untreated and one spare corner buster to decided where to put after experimentation.
First impressions(with only 3 corners busters) nothing,or so
i thought.My surprise was when i stood up and there was no extra bass.I thought "those 3 corner busters robed the few bass i had"and i took them out only to discover that it was now that the bass was gone.I just forgot how my system sounded untreated and was surprises after installing the corner busters.I do not expect miracles after installing the fourth one but all i can say is these things work and at $166 for 4 they're not expensive.I know i actually need bass busters but i am quite happy with the results i got from the C.B. ! Give them a try if you want.

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.

Re: Echo Buster "Corner Busters"

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.

Re: Echo Buster "Corner Busters"

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.

Re: Echo Buster "Corner Busters"

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?

Re: Echo Buster "Corner Busters"

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
