Alpha3, for your size room I would recommend going with a larger driver. I don't believe 10" is going to give you the volume and compression you need for movies.
I went through the whole subwoofer snalysis paralysis about 2.5 months ago and ended up pulling the trigger on two Rythmik Audio F-15's. I haven't looked in the rearview mirror once since owning them. Having done my homework I liked the fact that Rythmik was supplying a lot of seasoned DIY sub builders with their Direct Servo drivers and I appreciated the non-ported design for audiophile applications. I recommend you check into Rythmik Audio.
PS - I'm not a dealer, have no affiliation whatsoever with Rythmik Audio. I'm just a satisfied customer.
