super-v coaxial OB with a single boxed servo sub?
« on: 22 Oct 2011, 04:57 am »
Was wondering if one of the SW-12-04 in a sealed box with the 370 amp would be able to keep up in output to one of the p-audio coaxials used in the super-v set up open baffle.  In other words, a super-v with a sealed sub below rather than the two-driver open baffle sub section.

Thought just came to mind while pondering what a super-v center channel speaker would look like, assuming one couldn't make space somehow for an OB sub frame to go with it.

Thanks!

I think it would.

Thanks, Danny. :)

Sorry I didn't get a chance to make it out to RMAF - I couldn't get my work situation squared away quick enough to make it happen.

Two more (related) questions:

How do you feel about the idea of having the coaxial off axis vertically that much (say, about a foot lower than the three driver stack) if used as a center channel?  With a little tilt up toward the listening position?

(Thinking on the idea of making some sort of stand-mount monstrosity :green: ) How about doing the whole thing OB like the stock build, but flanking the coaxial with the servos M-T-M style horizontally?  Say, put the coaxials in H-frames as designed, keeping the baffle width on the coaxial basically stock?  Would it cause some cancellation issues with the servos due to the width of the coax baffle distance between the servo driver centers?

Thanks again!

No real problem there.

Flanking the Coaxial with a woofer on both sides of it could create a cavity resonance issue in some ranges. That might not work out real well.

Assuming height is your only issue and you have enough space to distance the center channel from the front wall since you asked about flanking the OB subs on each side of the coax, I believe you could lay the woofer section of the Super V on it's side and place the coax on top without impacting the response.  The result would be similar height to the boxed sub with the coax on top.

Best,
Ed

Ed - Yep, thought about that too.  Just thinking about ways to keep the footprint down in my hypothetical, although you are probably right in your solution would be the "best" ideal case.

All of this thinking came up as I was looking over some RMAF coverage here, and clicking around some google searches, I ended up reading a short stereophile blurb discussing a TAD room at a show that was set up to demo surround hi-rez with five channels.  Then I got to thinking that with the super-v's high sensitivity, you could probably run a multichannel setup with them to stupid volumes (or average HT-type stuff) if desired off of even the most humble of AVRs because the power output from the amp driving the coaxials doesn't need to be very big at all. . . could get to shopping for quality over quantity in an AVR rather than having to go dedicated pre/pro and amps needing less power, and still stay more on the affordable side.  Sure, may not be as subjectively "good" as splitting the amps off on their own, but in terms on simplicity, ease of use, etc. . .

Another dumb question - if I were to build out a single driver sub with a 4-ohm driver, could I repurpose one of my H600 amps to do so or would I end up over powering the driver?

You could over drive it if you turned the knob far enough.
