Hello again RO. Been an eventful and long time since I've been back here. I finally opened my studio, Vibrations Recordings in September of last year with so much incredible support from so many great folks here for the last 17 years or more!.

Recently Kmetal, who has become an incredible mentor and friend, and I, have been running REW programs to fine tune the CR. Room design and treatments along with speaker placement experiments have provided a relatively "flat" room response curve.The last thing needed is to tame a 60Hz bump. and the only viable options I've come across are commercial units costing up to 15k (eek!) or the use of a bass array with DSP to possibly utilize phase offsets to tame the beast.

Through my research the resources I found only seem to address using a bass array in a square room. My CR is a corner design. The rest of the response curve seems pretty good and translation so far of projects seems adequate. Perhaps I'm just naturally compensating for the 60 cycle bump?

Either way The REW results are consistent and I want to do all I can to control it within reason and cost. I'm wondering if anyone here has had any experience with the bass array solutions or have any other suggestions to offer?

I apologize for being so out of touch and hope to follow up with pictures of the digs so wonderfully saved by Rod G. after my humble attempts to do it all myself!
