What I didn't like about it was that it did not get much lower than 26hz but he has another older svs sub that handles the lower stuff. I am flexible with budget. Was hoping to spend less than the 1700$ that I paid for the SVS.
If I do decide to run multiple subs I really only have room to the left and right of my entertainment center. Will this provide enough separation? I do also have 10" powered subs in my towers that I have integrated and are using right now. I have 2 corners that are also available but I don't think they are an option due to the exaggeration of room modes.
I was looking at the iNUKE NU6000DSP which looks like it has cross over and built in PEQ as well as enough power for 2 separate subs if needed. Am I off base of this assessment?
What is a rumble filter?
I do agree that I probably don't need to add 4 high powered subs to the room. I am leaning towards a single 18 or dual 18 depending on what your responses are.
Thanks for everyone's help.
AFA sealed not having output down low, It really depends on how they are EQed and what room they are in.... In a room which does not provide enough pressure gain to flatten the response you can EQ the midbass down to yield a flat response, but that requires lots of headroom(ie army of sealed subs).
Since you don't seem to have much room gain(your SVS only gets flat to 18) and only building one or two subs, I think your on the right path with ported.
Running at the left and right of the Entertainment center should work ok, but don't count the corners out either so long as you can put a sub in each opposing corner...... I'd try both and measure to see which had the smoothest response. No doubt the corners would provide the strongest response.
The Inukes are solid amps. Prob not enough juice(nu6000) for two TCs or XXXs but prob about right for two HO18s. The dsp on that amp only goes to 20Hz though, same as the BFD.
With the modal issues you are likely to have I would recommend two slightly less expensive drivers which stay within your budget. You still should be able to achieve same output but in a slightly larger package with the benefit of multiple subs.
4 x Dayton Audio RSS460HO-4 18" Reference HO Subwoofer 4 ohm = $1000.00(Two per cabinet, ported to 17-20Hz).
1 x Behringer NU6000DSP ~ $425 on ebay
2 x Sheets MDF = $70
Hardware, wire, and finish $100
Total ~$1700. That should hang with a SVS Ultra
