Wanted to know if given a choice which would be the better sub. I do 75/25 ht/music. My room is 19x17 with 9' ceiling. Am using diva 4.1's and c3 with a pioneer 45tx. I could get the spl for about $150.00 more then the hsu. I've heard the spl but have not had any chance to demo a hsu. By the way i have all hardwood floors and except for a small rug, I don't have much choice at this time, but am working at it! Thanks, Rick Anybody have an extra pair or two of the diva 2.1's.
