Unfortunately not.. I dont have the stuff for that. Just going off of how it sounds and what I’ve read about placement. Seems like 2 subs up front isnt the best scenario usually and opposing corners are better so I figured I’s try that. I’m on a tight budget (reason for doing VBSS) so another $100 for a UMIK was down on my list. Maybe I should just get one and figure it pit..lol!Have you measured the room with rew? A measurement would tell us more than the use of the term "boomy".
IMHO, it is very important that you do.Maybe I should just get one and figure it pit..lol!

Until the mic comes in, experiment. With those room dimensions, I would pick a corner, place one sub 1/3 down the long wall, and 2/3 down the short wall from that same corner. Should get you in the ballparkI have 2 VBSS subs powered by a single NX1000d. I currently have them both in the front of my room. Bass is quite “boomy” but still shakes the house. I want to move 1 of them to the back corner of the room so the 2 are at opposite corners to see if this helps. Room is a rectangle 13’wide x 23 ft long with 7ft ceiling.
I currently have them wired together in bridge mode (so aprox 300 watts for each sub). Problem with that I cant independently control the phase. I can wire them up separately so I can set phase independently but might reduce the wattage (I think).
I dont have enough speaker wire to move them and try both options (bridged or wired separately A and B). And would rather not buy the wire just to experiment.
Will I lose much output by wiring them to the amp separately? I think wiring together in bridge mode puts out the most amperage per speaker.
Will adding the ability to adjust the phase independently outweigh the loss in power if I wire independently?
EDIT:
Just checking the specs from my amp.. The way I see it is, if I keaveit in bridge mode I get a total of 620watts output (to 2 subs). If I choose stereo it drops to 160w each but adds the ability to independently adjust the phase. I’m thinking thats not a good trade off.. I hat to lose the power by that much.. am I crazy?
I recently bought the NX1000d to power 2 of my VBSS subs. It may be light but even nust having the 1000, it these subs shake the foundation.. (and probably the neighbors too.) Fan Was definitely way too loud.. I replaced the fan with an all but silent one and its perfect. Literally took me 20 mins to replace it, no big deal imo. It may void the warranty but I could put the old one back in and no one would ever know so I’m not concerned about it.So I am still waiting on my drivers but the NX3000D just showed up yesterday. I just powered it on for the first time. Is this thing really the best amp option? It’s very light, doesn’t seem very well made and is loud as hell. I now know why there are so many threads on fan replacement. I honestly am worried that I just dropped $400 on an amp and I now need to consider opening it up voiding the warranty and attempting to replace the fan. But I can not live with that noise.
Well that's frustrating. I saw it change to "any day" earlier today, but I hadn't seen this yet. I'm tempted to go ahead and finish my cabinets and hope I cut the driver hole the right size.Anyone else still waiting?

I am tempted to just bag this project and buy anther SVS. Anyone want 2 mostly built cabinets?Anyone else still waiting?

This sounds pretty interesting, especially since it's unlikely I'll ever run more than the two I'm building off the 3000D I've got. I had planned to run my slot ported at the 20Hz most of the time and switched to 15 for movies, but now I'm not sure.If people are interested I could do a seperate DSP design for the Celestion T5867A Buyout, looks like PE has ~350 of them left. It is a 4 Ohm driver so you could only power 4 of them off of a single Inuke/NX3000, that said each driver would now also be able to pull double the power from the amp.
Output between 30-80hz would be roughly equal to the PA460 even with the extra power but around tuning it looks like the Celestion could pull away by almost 6dB, so one of these would be nearly as capable as two PA460's at low frequencies.
I'd only do the 20hz tune as port velocity and cone excursion are too great at 15hz.
At least that's what the sims show. Part of the reason the PA460 works so well is that it's very compliant and the suspension produces little noise even past the rated xmax. If the Celestion suspension locks up near it's rated xmax it may not perform as well or as cleanly at low frequencies. The same questions could be had for the PN470.
