Trying to maximize bass response ......

I've a system set up on a 13x19x9 ft room and have optomized set up (considering all of the variables and domestic no-no's). Referenced to a 1k and 200k tone using a Stereophile disc and RS meter, I have a fairly flat response to 32hz and a sharp fall off thereafter EXCEPT for a sharp dip at 50 and 40 hz (8 and 6db respectively).

I would like to fill in the 40/50hz null and would consider filling in the bottom octave by using a sub if it wouldn't end up with a sharp increase at 32 hz.

BTW the 40-50 hz drop out is definately room related - its there with panels and cones and pretty much independent of set up on the short wall and location of listening position. Long wall set up is not an option.

Any suggestions will be appreciated including those suggesting that I should just forget it and enjoy what I've got.

TIA

That's not bad at all considering the meter isn't all that accurate. You must be sitting in a spot where these frequencies cancel. Move things about.

I believe the parc is only for reducing, not boosting to fill in.

While flat is a worthy goal it is pretty much impossible to obtain in a room. Music is usually a series of impulses (notes) not test signals. I bet if you played a series of notes from 32 to 50Hz or above on a bass guitar you wouldn't perceive that 8 dB dip that you measure.
