jtubbs6117 Posted June 14, 2015 Share Posted June 14, 2015 I know that this system requires you use the klipsch KA1000 thx. But why? Is this only to make sure you have the THX2 certification? Could an inuke amp not drive 4 of these or a pair? I understand the signal path wouldn't be THX2 certified but it would sound great? I have thought about looking for the subs for cool fall project. Looking at the spec of the THX subs they are 8 ohm perfectly capable to be driven by the inuke or your amp of choice. Quote Link to comment Share on other sites More sharing options...
willland Posted June 14, 2015 Share Posted June 14, 2015 Jeff, Jeff, Jeff, I know you know that you do not have to use the KA1000 to drive those subs. An Inuke, Beringer, Crown, etc. all would work with the THX subs as long as you match the power properly. Heck you could properly use your Anthem amp and an X-30 crossover to drive at least two of them. Let the subwoofer separates guys chime in with a proper amplifier match recommendation.

jjptkd Posted June 14, 2015 Share Posted June 14, 2015 I use a Samson SX3200 at 750x2 @ 8 ohms to drive mine and they sound great. Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted June 14, 2015 Share Posted June 14, 2015 yeah i think its really just a power match up and hp/lp filter thing. they know exactly what the amp is powering so they can tailor it to it. inuke would drive them just as good if not better as you can eq more than what the thx amp allows and they are much cheaper.

Paducah Home Theater Posted June 15, 2015 Share Posted June 15, 2015 It's because the amp has an internal DSP that is specifically tailored to those subs just like several other factory subs do. Other stuff would drive it fine but you'll have to dink with the dsp and whatnot to get it flat. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted June 15, 2015 Share Posted June 15, 2015 The big thing with THX is to obsereved the 80 Hz xo, remember the 12 db roll-off and you are good to go. The I Nuke, Crown, QSC or other pro amp should work fine for the speakers. Quote Link to comment Share on other sites More sharing options...
jtubbs6117 Posted June 20, 2015 Author Share Posted June 20, 2015 This should have been titled THX ultra 2 vs DIY. That was my mistake. I am looking toward a fall project that will allow me to add some bass to the living room and possibly move the PB ultra somewhere else. The amp will be the same Inuke 6000DSP but would you choose 2 SI HST 18's these look sick and have crazy motor travel. Or two THX ultra 2 subs? Power being the same so that variable is constant. Please understand the only sub I am using in the living room right now is the PB ultra 13. Thanks guys I hope this one has some good feedback Quote Link to comment Share on other sites More sharing options...
willland Posted June 20, 2015 Share Posted June 20, 2015 (edited) Okay Jeff, I know your room is large, how large is it? What are the cost of each option? Bill Edited June 20, 2015 by willland Quote Link to comment Share on other sites More sharing options...
jtubbs6117 Posted June 21, 2015 Author Share Posted June 21, 2015 If memory serves me. Volume on the open space 6600 cubic feet. Cost for each setup is basically the same 1800. Quote Link to comment Share on other sites More sharing options...
jtubbs6117 Posted June 21, 2015 Author Share Posted June 21, 2015 DIY cost: pair of subs $1070.00 amp $399.99 pair of boxes $240.00 = $1709 Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted June 21, 2015 Share Posted June 21, 2015 DIY subs all the way. A couple of large vented boxes will blow your socks off, lol. Quote Link to comment Share on other sites More sharing options...
jjptkd Posted June 21, 2015 Share Posted June 21, 2015 Each room is going to be a bit different. My friend has a DIY vented 18" sub with an iNuke 3000 dsp and it sends out quake type waves that are awesome for movies. My Ultra 2 subs send a rumble through the floor that is quite nice but also has the cheek flapping ability and precision that is scary. It seems to me that the Ultra 2's are somewhere in the middle of the large 18" vented enclosure and the nice tight accurate RSW-15 but quite a bit louder than both. Basically the Ultra 2's do better for music than the 18 but not as good as the RSW-15. The Ultra 2's do better for movies than the RSW-15 but not as good as the single 18. Hope this helps, good luck!
