Bass response

[MJL777]

How much would I need to do to flatten my room response if from 80Hz to 20Hz the average level changed by 4 to 7dB every 10Hz?

Bass is difficult to measure accurately. But assuming the readings are correct the treatment would depend on why it is happening. You may be able to get acceptable results by moving the sub or adding bass traps.

Not knowing what the readings are and which method was used to obtain them makes it difficult to diagnose, the following is a suggestion using pure speculation.

Try using the compensation chart for the rat shack sound pressure meter.

As much as you are willing to do.

Like all audio reproduction issues, a flatter response generally results in much more realistic and enjoyable listening. As such, I have always recommended, in order of importance, careful speaker placement, careful listener location choices, applying room treatments, and lastly the judicious use of EQ to get a relatively flat response in the bass.

The flatter, the better, but don't rely on EQ alone to accomplish a flat response if you want the most enjoyable and realistic reproduction.
