subwoofer question......what size sub ?

have a pair of Proac Studio 200 speakers and thinking of adding a sub....but with the drivers in the Proacs being 7", what size sub ( driver ) should be used ?     keep it close to the same size or go with a 10-12 driver ?

what brand of sub works well with Proac ?

bdp24: absolutely. It is for the same reason that I like my Quad electrostats. Speed is indeed not a property of the speakers but of their interaction with the room. I wil look into the 8 inch version. Thanks

Regarding an omnidirectional approach for the mono setup of subs, and in my case the GR Research/Rythmik OB sub combination. For me, my setup is for stereo. I reached out to Danny of GR research and he replied...
"If I had two of the subs then I'd run them in stereo. They are only omni in the first octave and a half or so, then directionality begins."

Power Sound Audio have a wide variety of subwoofers with some of the most generous options such no shipping charges and a 5 year warranty.

FWIW I have used  Entec, Vandersteen, Velodyne and REL subs with 4 different series of Proac speakers.
My ears like the REL  products. They are fast and accurate, not to be confused with subs that make Top Gun(and Tom) sound great!
They have a very simple attachment method that takes the output from your amps speaker terminals. Very adjustable and I have yet to find a room that they can't be tuned to work in... YMMV.

Get a 10" woofer model and start the learning curve about room resonances and standing waves.
The Proac/REL combo can be very rewarding.
Good Hunting!

If you look at speaker driver's data, you find 8" to 10" bass  speakers perform the best in the right cabinet. An 8" in a transmission line cabinet may be better than a 10".

Cone speed is as important as frequency response; the greater the mass of the speaker cone, the higher the risk of latency. If speaker cones (tweeter/mid/bass) have different latency, sound gets out of phase.

Martin Logan's electrostatics are classic examples of this where they struggle to get bass and panel phasing correct.....personally I never liked the sound of them for this reason. Quads had poor bass, but the phasing was lovely, sorry, getting off topic.
