I have an annoying boomy resonance in my listening room at about 68Hz. I don't want to insert any filters into the signal path to my amp (Q909).
My speakers are Magneplanar MG1.6 and go low enough but can't be relocated to a position which doesn't excite the eigentonesso much.
So I was pondering on placing an unused sub near my listening position driven with a Dayton Audio DSP-LF and spare amp. In this case, adjusting the response to cancel out the boom rather than boosting the low frequencies.
Doable?

Following with interest. This is somewhat like the concept of noise cancelling in headphones, car interiors, etc.
Yes, that's the aim, though not sure whether the DSP-LF will be able to produce a narrow enough 68Hz peak as the Q seems limited to 1.41 max
I think Rod Elliot's Project 218 might be a better choice.

Hello,
I have also had problems with standing waves.
A good description and solution can be found here.

I used a DSP amplifier for my passive subwoofer.
It works very well.

Many thanks for the link about elecgtronic absorbers, it makes for interesting reading and shows that they not only work but are also effective..
