Please help with subwoofer.


I'm considering one new Velodyne HGS 18 Series II with a 1200 watt amp ....or two Velodyne F-1800 with 600 watt amps. My room is 22ft wide and 70 ft long with 22 ft high ceilings....carpeted concrete floors and concrete ceiling....the building was once a beer brewery and has been converted to live-in lofts. Will the one Velodyne HGS 18 do the trick or will the two less powerful F-1800's be better. The cost for one new HGS 18 is the same as two used F-1800's...$2000. I've never owned a sub before and I'd appreciate your input....thanks.....Mitch

Albert....What is the relationship of woofer size and amplifier to bass production? I looked up the REL specs and the Stadium III is a 10 inch woofer with a 300 watt amp. The Velodynes that I'm considering offer an 18 inch woofer and a 600 watt amp for the F-1800 and a 1250 watt amp for the HGS 18....Are the REL's that prodigious in their bass output? A seller is offering a pair of Velodyne F-1800's for $2k. Will the 10 inch driver in the REL deliver the goods in a room my size?
Albert......for music, I'm content with the bass output of the Kappa's. The only reason that I'm even considering a sub or two is that when I use the Kappa 9's when playing dvd's....the bass onlslaught sounds like it is going to rip my speakers apart and I fear for the lives of my speakers..I'm talking about dvd's like 'Gladiator' and other dvd's that have that killer bass and gut wrenching explosions. So, integration for music is not an issue, this is strictly an HT thing. Right now I just want relief for my mains and fix the HT bass issue. I'm pretty new to HT. Maybe in a year or so when I get some more money, I'll start experimenting with subs to augment my 2 channel setup. Thanks Albert for your input. Anyone else here care to jump in?
