ProAc D2 & REL T-Zero mk3


I just ended my love affair with my Sonus Farber Concertino’s and picked up a fabulous set of ProAc D2’s…they are really fantastic. 
So my question here is, I have a REL T-zero mk3 that I was using with the Concertinos. This little sub only goes down to 30hz which is what the ProAc’s do as well. I tried them together with the crossover dialed up at just 2 clicks and while it sounds nice I’m wondering what I’m missing out on with a bigger sub. But at the same time my room is only 12w x 15d last thing I want is bass overkill.

thoughts?

Congrats on the new speaker purchase.I would suggest trying a single T 7x or 9x and see where your at....then if or  when funds permit add a second one.The S510 is the best option in my opinion (a pair actually) and would be fine in your room.
proac d2’s do not extend flat down to 30 hz... not even close... the stated specs list 30 hz response limit but without a +/- db indication...

if they in fact do 30 hz they have got to be minus 8-10 db down from 1 khz... so proper subwoofer augmentation will absolutely present a true full range response, and a pair of rels would be great for that purpose... larger ones if you have a large room
@jjss49 excuse my ignorance, I assumed they go that low being that they easily handled a 30 hz test tone. The little REL doesn’t go to 30 hz either. The crossover dial is marked 30hz - 120hz but the specs have it at -6dB at 37 Hz
