Are movies like Transformers and World of the Worlds going to be a problem for this sub.
I can touch on this since I've tried both movies. Simply put, no, these movies are no problem for this sub. I'm sure RMK doesn't push his subs as hard as I do since he has 2 to balance the load along with the other array of subs he has in his system.
When I first received the sub, Jeff and I found an issue (defect) with the PR surround, the surround was not stiff enough and would cause a buzzing flapping noise during heavy load. He had another PR for me to swap out with and it solved the issue. Mind you I push my sub with a QSC 1850hd amp bridged mono outputting 1800W. I have the gain set around 2 o'clock for normal tv viewing and 3 o'clock for movies and music. I have my sub gain is set to max (10) on my HK receiver so I'm pushing the sub pretty hard. I watch most movies between -17 to -10dbs and both movies sound fantastic. WoTW scene when the pod first emerges is really no big deal. TF2 towards the end when the plane drops the line of bombs sounds really tight, you can feel it in your chest. The entire final scene is pretty crazy. The Hulk scene with the sonic cannons push the sub pretty hard but no distortion or bottoming out. Also star trek's opening scene has massive ringing bass when the ship flies by but the sub handles this well. I stare at the PR during these scenes and the excursion is pretty intense. The only buzzing, flapping, or bottoming out noise comes from my walls.
BTW my room is 18'x22'x6.75', the floor is concrete with a drop ceiling above, no acoustical treatment yet. I did not measure levels, I do not have the equipment but Jeff did some measurements and testing. Maybe he can share his numbers.
