Subs for Magnepan 2.7's

I picked up an ACI force sub, and absolutely love it. It is very fast and tight. I have AP sparks, which are fast speakers, and I cross over at 65hz, and this sub disappears into the soundstage. Kick drums are dead center and deep on rock & roll. This sub sounds like it is exactly what you are looking for. There are two crossover filters and a variable phase pot. Takes a little time to set up but well worth the effort. Hope this helps.

Maybe I can help - I have 3.6R's and am using Revel Concerta B12 subs with them and the fit is amazing! The B12's have a parametric equalizer in them, are non-ported and very fast and pitch accurate. They should blend well with your speakers and they look great in the cherry finish - even if it IS just a vinyl coating! At $995/ea retail, they are affordable as well. Good Luck!

Thanks everyone for your input. I'll look into the Revels, too.
