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.
