Originally, both old (Klipsch THX Ultra2) and new (M&K S5000THX) systems, I used 4 KW-120’s stacked (coupled) in the front right corner of the room powered by two KA-1000 amps. I moved one sub to the opposing corner of the room and with one sub in each corner, ran the Trinnov optimizer and viola! ALL 7 speakers cutoff at or below 80Hz for the first time, with either system!
Utilizing the “more is better” mentality, I then added the other two subs (and the second KA-1000 amp) and ran Trinnov again. In frustration, I recreated the null with the higher crossover (around 150Hz).
Are the 4 subs too much for a VERY large room (17’ wide x 30’ long, 10’ ceiling and lot’s of glass) with an adjoining room (kitchen/breakfast)of similar size along the right (24’ open) side?
While I’m frustrated as I thought I had the null resolved, I know how good Trinnov can sound with this receiver and want to get it right!!!
Thanks for any additional input!
