I really am liking the look of Duratex, and this is just the first coat I applied on my dual opposing subwoofer enclosure.
I'm highly thinking of building another one, and powering it with this amp.
So you toss in some WinISD results, of the 8 ft^3 enclosure, with two Dayton RSS460HO 18" drivers in that enclosure, and feed it 2,525 watts of power, here are the SPL calculations down to 7Hz. For just a single cabinet:
Now, add in the second cabinet, and the second amp channel for the additional power, you'd add about 6dB of overall SPL output.
So about 102dB at 7Hz, 108dB at 10Hz, 120dB at 20Hz, and 126dB at 30Hz for example. It could vary per frequency still, depending on how things react in my room. Though this will be fantastic for movies, games, and music.
