Can you use an 2x4HD behind an 88A if I want to utilize 4 subs and then apply Dirac?

hi,
yes you can do that, i've a DDRC88ABM and the .1 output goes into my 4x10HD for the subs. i would do the subs matching first on the 4x10HD, you can see many multisub vids on youtube  how to do that so the four subs work together and then do the DDRC88BM dirac measurements.
works great. 

have fun!

Thanks. That’s exactly what I’m planning as soon as they’re back in stock. 

Yes, i do the same with Shd+2x4hd

I’m going to be doing exactly that until the 88A is back in stock. I’m putting the 2x4 behind the SHD so that I can use my preamp’s HT bypass. Does DIRAC work well in this setup?
