Can this be used with 3 (or 4) subs to set them up for use with Audyssey (or other AVR-based room correction system) like with the older 2x4 HD?

Thanks,

->g.

Would you have a device with Audyssey send a sub output signal to the SHD?

You could connect upto 4 subs to each SHD output but you would probably be better using Multi Sub Optimiser (MSO) rather than Audyssey.

And you might find the DDRC-24 a more cost effective option.

It would indeed work fine. REW (with MSO) or Dirac Live will work fine. 
Here is an example application with Dirac Live. www.minidsp.com/applications/subwoofer-tuning/ddrc24-multisub

You'd typically run the tuning first and then Dirac Live on top as a single channel: www.minidsp.com/applications/subwoofer-t...tuning-multiple-subs

I think a 2x4 HD would be the most appropriate product here. I see little benefit from the extra cost of an SHD personally if all it will be doing is sending signals to subwoofers. Dirac Live on either an SHD or DDRC-24 would also be of no use - it need requres full range speakers to be involved.

I have a Marantz SR8012 with Audyssey MultiEQ XT32.  I wanted something a little higher end than the 2x4 (or DDRC) and something that would be easier to manage my three subs.  I managed to get pretty good results as is (probably because two of my subs are in mirror image locations of one another) but they are a pain to deal with whenever I re-run Audyssey.  I don't see how connecting multiple subs to one SHD ouptut would be a benefit over what I'm doing now (two subs on a y adapter to AVR sub out 1, 3rd (near-field) sub on AVR sub out 2).  Having complete control over each sub individually (with Audyssey seeing them all as one) appeals to me.

I'm also contemplating new subs in the same room for a dedicated 2 ch system that I have in that room.  I could then use the SHD for L/R fronts + one or two subs.

Hi, you've misunderstood.. No one is suggesting multiple subs off one output. Each output would have an individual sub. Then MSO would generate all the time delays and filters on a sub by sub basis.

I definitely got more consistent bass across the lower frequencies with two subs. I think as a rule you want the distances between subs and listening position to be as different as possible. I found best results with diagonal placement rather than mirror imaged.

"You could connect upto 4 subs to each SHD output" - Sounds like one output with multiple subs to me.

I found best results with diagonal placement rather than mirror imaged. 

My near-filed sub is on the diagonal to the right front.  I don't see how I could have 3 subs (in a square/rectangular room) all on the diagonal of each other.

The suggestion of connecting 16 subs to the SHD would to most seem a little err extreme :-) but I note your point so see correction here:  "You could connect upto 4 subs, ONE to each SHD output". 

You wrote that you "could then use the SHD for L/R fronts + one or two subs". My recommendation is two (if you have them) and placed different distances from your listening position. Diagonal corners worked best for me.

Gotcha.

Only got room for smaller, sealed subs next to the existing (mirrored location) subs. Haven't decided to go this route (more subs) anyway. Need to see if I can dual purpose my existing subs first.

In our main living area I have a sub that is dual purposed. It's an older Rel when they had Left and Right inputs. We have the L connected to an AV amp for the TV's 5.1 and the R is connected to an amp that does the in-ceiling speakers. 

So long as both amps aren't on at the same time it seems to work fine. 

Some subs have two inputs where one has a higher/lower gain.. I'd imagine these two inputs could be used in a similar way as the L + R described above.
