Two subs - should they be the same size or is different ok


I have a nice setup: McIntosh 352 integrated tube amp, VPI Signature table, Revel Studio 2 speakers, and 2 SVS subs - the SB2000 and SB3000.

I initially bought the SB2000 since I had a smalleer room at the time, and then got the SB3000 when I moved into a larger room - about 18' x 24'.  Then I thought - why not both?

I've have read that sometimes other Revel speakers are a little weak in parts of the bass spectrum.  I think the latest review was from Audioholics, although I'm not sure that was a fair comparison since one of the Revels seemed to be placed partly behind a couch.

However, I like the two different sub sizes because I can set the smaller one to engage at 68Hz and the larger one at 62 Hz.  So I can adjust not only the volume of bass but different parts of the audio spectrum

Is this logic valid?

There is no advantage to different crossover points. In your case you will have slightly less out put of note C2 at 65.406 Hz. Gain levels should be close which can be more challenging with mis-matched subs.

According to Revel the Studio 2's  3 db down point is 32 Hz. Normally for best results your crossover point should be in that vicinity.  Usually, slightly lower. The goal is to try and create a quasi 1st order crossover (6 db lower at the crossover point) between your subs and mains.
