I am putting the final touch on my HT system-a sub. I'm not looking to rattle the knickknacks or crack plaster. I just want to fill out the bottom end of my system, which is: fronts: Paradigm Studio 40s rears: Paradigm Mini Monitors center: Studio CC receiver: Onkyo 696 I live in an apartment (top floor), so I have to be careful about my neighbors. I can get complaints from the downstairs neighbor sans sub. The room size is approximately 12' x 17'. So my dilemma is, do I go with 8" or 10" sub? I really like the Energy exL10. The Energy S8.2 (a brand-spanking new design) is also decent. Others I'm looking at are the Velodyne CT80 and CT100. I use my system for 50% music and 50% HT. Any suggestions would greatly be appreciated. Thanks!
