Subwoofers for Magnepan 20.1s?

I used Granite Audio's Ultimate Low Bass CD and my 20.1s go to 25Hz at -10dB and my room is 16x26x10 (speakers approx 6ft from back wall and 3.5ft from side walls on ends). I can get -6dB in the 29-33dB range and then it is pretty flat with a slight drop in the 50-60Hz range. I am not a bass fanatic, but on some recordings, I wish I had some further lower bass extension without becoming unnatural sounding/boomy. I know HP likes Nola Thunderbolt subs with the 20.1s. Has anyone tried them or any others? Other system components: Pass X250.5 amp and Xono phonostage, Audio Research Ref 3 preamp and Ref 8 CD player, VPI superscoutmaster reference turntable/10.5 tonearm, Dynavector XV1S cart.

You didn't mention price but with Maggies,Quads,NL's without built in subs you have a need for speed.You'll be happier if you give up octave or epth for transparency.I have been fan of REL's older series (or a spin off company MJ Acoustics) because they used multiple drivers to equal one large plodding sub which is fine for HT but not transparent speakers.Maggie themselves say "Don't go larger than 8" woofer" because they know you might shake the foundations with a Velodyne,JL,or other monster but not get neutrality that blends.I have not heard it but read review of TBI Magellan VII one amp/x-over double box system but 6moons said it was fast and neutral.You might want to check out Martin Logan and though head to head they are supposed to be more like a HT sub than REL they are deep and have multiple drivers for speed.Add a Velodyne SVS external DEQ (not expensive flip it easily if you want) would be last tip.Might improve outcome.But go for transparency,speed resulting in transparency.Now I am going to read about the Nola myself!!!!!!
