NBPK402 Posted January 17, 2014 Author Share Posted January 17, 2014 Ok... Now I understand. The ones he is using are 13.8cf x10=138cf, which means he is doing x6 with 8 of them. Quote Link to comment Share on other sites More sharing options...
homeskizzle Posted January 17, 2014 Share Posted January 17, 2014 It's about 600 watts per driver. I use a Behringer EP-2500 (EP-4000 now) wired @ 2 Ohms a channel. I may have left a little in the tank but I didn't want to break anything. Have you had any issues at all with running the EP @ 2 Ohms? I've heard conflicting reports and wanna get your take on it.

Over 7 years without a hick up. HT doesn't tax an amp like using it for live sound does. It's not constantly being pounded when you're watching a movie like it is for DJ or concert type use.

NBPK402 Posted January 18, 2014 Author Share Posted January 18, 2014 (edited) I am torn between doing the IB setup and going horn loaded... I have seen the TubaHT and the THSPUD... Both look like they would be easy enough for me to build and less expensive than the IB setup. The more I look the more confused I am. The Tuba HD looks like it would do everything I want at a low power just like I want but when I look online I hear that the IB will go lower and louder with the same power... But then I see how much power the IB will need and how much the horn loaded will need and it seems the tuned horn is the winner. Can someone explain to me why I would want to go with either of these setups? I would like to hit reference levels (HT) with 400w or less @15hz or lower.

psg Posted January 18, 2014 Share Posted January 18, 2014 Do you mean Tuba HT? No way you can hit 15 Hz hard with it AFAIK. I'd say 19 Hz. So maybe go IB? Quote Link to comment Share on other sites More sharing options...
RRR Posted January 18, 2014 Share Posted January 18, 2014 Burn yourself a 10-20 Hz sweep and see how low the THT really digs. I was able to shake the house using only 20 watts with my 24" THT. Quote Link to comment Share on other sites More sharing options...
psg Posted January 18, 2014 Share Posted January 18, 2014 Already have. Bass response is very room-dependent anyway, but I don't recall people bragging about the 15 Hz capability of the THT. BTW I didn't say that I couldn't shake the house with 20W; I just wouldn't be doing it at 15 Hz. I put in a high-pass filter in the low teens anyway to avoid over-excursion. https://community.klipsch.com/index.php?/topic/120571-diy-sub-for-klipschorn-based-ht-and-music-tuba-ht-build-done-except-for-finish/page-26#entry1664879 Quote Link to comment Share on other sites More sharing options...
tromprof Posted January 18, 2014 Share Posted January 18, 2014 Another horn sub design to look at is the Cinema F20. Doesn't go much (any?) lower than the THT (solid at 20hz, but not much below) but much easier to build (but bigger footprint). It has fewer pieces than a THT and after cutting wood it only took an afternoon to assemble. By contrast my tuba table was a PITA to put together, though still a very nice sub.

RRR Posted January 18, 2014 Share Posted January 18, 2014 I used the Dayton Classic with only 8mm of X-max and never had a problem with overexcursion, i would guess they're not needed. According to Bill the THT reaches maximum excursion @ 22Hz and drops below that. No bragging just stating my experiences. Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted January 18, 2014 Author Share Posted January 18, 2014 What about the THSPUD? It looks like it would be easy to build, efficient and I could put 4 of them in the room. Would it be fast enough, efficient enough to keep up with the La Scalas? Quote Link to comment Share on other sites More sharing options...
psg Posted January 18, 2014 Share Posted January 18, 2014 Any of the THT, dual SPUD, Cinema F20 or lilwrecker will keep up and then some. Tapped horns (such as the SPUD) absolutely need EQ while horn-loaded subs still benefit from it, so factor that in as well. Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted January 18, 2014 Author Share Posted January 18, 2014 Minidsp would do the job correct? Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted January 18, 2014 Share Posted January 18, 2014 (edited) The Mini DSP should be adequate. Amps like the Behringer DSP units have a very nice DSP and have plenty of power to drive a HT subwoofer. As far as quickness of a sub, that is more related to proper integration and setup.

mustang guy Posted January 18, 2014 Share Posted January 18, 2014 Do you mean Tuba HT? No way you can hit 15 Hz hard with it AFAIK. I'd say 19 Hz. So maybe go IB? Maybe if you could extend the THT hornpath another 6', but that would require wrapping the horn around two more sides of the existing driver, and the horn mouth would be as big as the whole THT you started with.

NBPK402 Posted January 18, 2014 Author Share Posted January 18, 2014 Here is a question... If I was able to find a set of plans for a THSPUD, could a person make it 22" instead of 11" wide and put in 18"ers to get the efficiency up and dig deeper? Maybe run 2 of them behind the screen plus 2 THSPUDs under the back row seats. Quote Link to comment Share on other sites More sharing options...

mustang guy Posted January 18, 2014 Share Posted January 18, 2014 (edited) Here is a 15HZ THT, I don't know what driver you would need, but I figure you would need something with different TS specs.

RRR Posted January 18, 2014 Share Posted January 18, 2014 The Table Tuba & the THT both have 13' horn paths yet the THT easily digs lower in frequencies than the TT so it can't be just the horn length making the difference. Quote Link to comment Share on other sites More sharing options...
