My question is how bad can this be for the subwoofer?
The funny think is that a friend of mine is running a VTF3.2 and can get as much bass with less gain in a similar size room...
That does not make any sense. Have you tried his sub in your room? In our 14 x 31 ft demo room, we have one 15H, volume at 1/3 of a tick up from minimum (1/3 of the way between minimum and the nine o'clock position), sub out level at -5 dB on a Pioneer VSX-1018 and the walls are shaking!
Can you send a sketch of your room? Please include adjoining room details if they are connected via doorways that are open when you are listening. Sketch in the listening location, where the sub is, and the distances from the listening spot to the nearest walls.
At that volume, you are pushing the sub pretty hard. Not the best for long term reliability, although the 15H can take that kind of beating better than any sub we know, but still not advisable. If you like that much bass, add a second one when you can. That would help a lot.
