Suckout at 40 hertz...less pricey solutions?


Can bass traps or other room treatment help with measured 40 hertz bass suckout?

Problem is my listening room is almost a square.

My speakers Have powered woofers and try as my speaker dealer has to dial in the speakers he could not eliminate the 40 hertz suckout without making matters worse

my four walls and ceiling have absorption material and the ceiling is not flat nor low. It's a sloping ceiling 9-12 feet

I could massage part of the problem by adding an additional powered woofer to the speaker . The upgrade to my model is designed to have a powered woofer On top and bottom.

Cheaper of course would be room treatments

most expensive would be knocking out a wall making a rectangle but that in my converted garage would be the most pricey!

Any thoughts

thanks

ps. Room sounds good but would like to within reason maximize potential of my excellent equipment

A Behringer DEQ2496, which you can get (with mic and cable) for about $350 will show you what your problem is with its spectrum analyser (Real Rime Array, RTA). The RTA will also help you see the effectiveness of various room treatments that you might try. Oh, and by the way, you can also correct the problems using the equalizer function. You will no doubt recieve comments that the equalizer aproach won't work. I say, try it, and decide for yourself.
I will second what Eldartford said. I won't go back to a system without a DEQ of some sort. More people need to give these a try and see what happens.
