Quadraphonic Posted February 22, 2023 Share Posted February 22, 2023 I am in the market for a subwoofer to compliment my new Cornwall IV’s. Having never had a sub in my system I would appreciate some advice in choosing appropriately. 1 sub or 2? Size/power? Connection? My Amp/preamp has no sub out. Is there any truth to the rumour that Klipsch is bringing out a new line of subs ? Quote Link to comment Share on other sites More sharing options...

Right now I would not buy a new Klipsch sub unless something new and great were to be revealed the low dollar options may be tempting but you really do get what you pay for. Lots of great Subwoofer companies out there offering free in home trials need to narrow down what it is you're looking for to get any good suggestions. Congrats on the new Cornwalls! 2 Quote Link to comment Share on other sites More sharing options...
Peter P. Posted February 22, 2023 Share Posted February 22, 2023 Cornwalls are brutally efficient; you'll have to get a subwoofer that can match it. In the case of a subwoofer, you're looking at amp power, not efficiency because efficiency isn't a spec for subs as far as I know. And for no technical reason I can come up with, I'd recommend you get a sub with the same size driver as your 15" Cornwalls. I recommend buying 1 subwoofer to start; you may be satisfied and you'll save money and space. Quote Link to comment Share on other sites More sharing options...
Shakeydeal Posted February 22, 2023 Share Posted February 22, 2023 I don't think a 12" (or a pair) will be able to keep up with the high output of the 15" woofers in the CW IV. Look for 15" or bigger. I do advocate for at least two subs. You can tap off the outputs of your amp going into the high level inputs on the sub. That said, you don't need a sub out. An additional line out from the preamp section will suffice. Quote Link to comment Share on other sites More sharing options...
Fido Posted February 22, 2023 Share Posted February 22, 2023 I had an 15” HSU Sub I used with my Forte IVs and it sounded good. I had a chance to get a REL S812 sub and the REL was a much better match in my system. The REL is fast and integrates seamlessly with the Forte IVs. Really just made the Fortes sound like much larger speakers and tremendous bass and mid bass is fantastic. 1 Quote Link to comment Share on other sites More sharing options...

Thanks for the advice jjptkd: The room is 32 x 24 x 12 . Soon to have 4 - CW IV’s in the corners. I don’t know if it’s ever been done before, or why, lol. Perhaps your suggestion to try one/ them out would achieve the best results. Quote Link to comment Share on other sites More sharing options...

wuzzzer Posted February 22, 2023 Share Posted February 22, 2023 I’ve always been of the opinion that any subwoofer you’re using should have a woofer that’s at least as big as the woofer in your main speakers. 1 Quote Link to comment Share on other sites More sharing options...
Dave MacKay Posted February 22, 2023 Share Posted February 22, 2023 My 2 cents … - more than 1 sub provides a great deal more capability in taming room modes (esp. below the. Schroeder frequency). I’d suggest either 2 or 4 subwoofers - use a MiniDSP 2x4HD to integrate the subs - horn loaded subs are available, but often involve DIY. Check out Bill Fitzmaurice’s designs. I built 2 of his THTLPs and have been very happy with them - consider other brands than Klipsch for subs. Klipsch does many things well, but I’ve not been impressed with their subs. 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted February 22, 2023 Share Posted February 22, 2023 2 hours ago, Quadraphonic said: The room is 32 x 24 x 12 . That's a good size room. Mine is similar but with a corner chopped out so L shaped. And only 9 foot ceilings. I have two Danley TH subs that keep up nicely with the Jubes and add the extra oomph in the bottom octave. Can it get too loud? You betcha. But you will be amazed at how much bass a room that size can swallow up. And how well it can sound at moderate levels with multiple subs.

Yep That 's a pretty large size room you got there + 2 pairs of CW IV , 1 Klipsch KPT- 1802 -HLS Cinema sub can do the job , but it's a special order / horn loaded subwoofer with a Patented vented LF , alike the 36k$ Jubilee . https://d2um2qdswy1tb0.cloudfront.net/product-specsheets/KPT-1802-HLS-Data-Sheet-v04.pdf 1 Quote Link to comment Share on other sites More sharing options...
John Chi-town Posted February 22, 2023 Share Posted February 22, 2023 I would also look at SVS subs. They have a great try at home program as well as upgrade policy where if you feel you need more, they will credit your purchase price for up to 1 year, on a larger, or different sub.

Your space is pretty large I think you're probably better off with a pair of larger driver subs in ported cabinets. Rythmik, HSU are a couple of highly rated "budget" subwoofer companies. http://www.rythmikaudio.com/products1.html https://www.hsuresearch.com/subwoofers.html 1 Quote Link to comment Share on other sites More sharing options...

Initially I assumed a single Klipsch subwoofer would match this system but this community has been immensely helpful with all of your knowledge and experience. I will find out what a mini DSP is and I will check out your suggestion. Thx Quote Link to comment Share on other sites More sharing options...

I guess I’m back to saving up for some subwoofers. Maybe 2 CW IV’s and 2 subs would have been a better decision.
