If your price range is between $1-2k and you want to take the guess work out of so called matching?

This little Velodyne Plus has one of the highest levels of on board remote controlled Digital Signal Processing which provides an incredible level of Room Optimization automatically with any speaker. Or, to adjust eight parameters of EQ manually and store in six different presets to your personal taste manually.

I suggest comparing your short lists setup procedures in their user manuals to get a better idea of subwoofer advancements. 
I’ve owned subs from SVS, Velodyne, JL Audio, Seaton, Vandersteen... I am now running Rythmik with my Raidho D1’s and recommend the pairing higly.
What Rythmik subs are you running? I’ve heard great things about them and their ability to integrate with monitors.
When I had D1's I tried to integrate a Rel B3. While I got the lows I was looking for the B3 just bled too much into the mid's changing the magical mid range too much. I tried for over a year to get it right but it just didn't happen for me. The solution in the end was to get D2's.

That said as much as I loved the D2.1's which I got later I found the mids were a world better with the D3.1's. For me I heard too many D3.1's - 4.1's and D5.1's. I guess I'm too picky.
