I'll stay with my Danley Sound Labs DTS-10. It has a smaller foot print, is more efficient and still produces a continuous 127dB 15 Hz- 70 Hz - 3dB and 133dB peak with 1000 watts continuous ( not that I push it that hard in my den). Bottom line is I like it.
Or would you suggest an Atmos array. Floor, mid wall and then in-ceiling? This could be the best I'm guessing. So if someone is sitting on a bar stool versus a recliner, they will have vertical linearity. I'm definitely thinking about this right so don't tell me otherwise.
