Fastest subwoofer?


Hello, I would like to buy a subwoofer that complements a pair of very fast speakers. I know very little about subs since I rarely used them, and I am wondering what are the models that are considered to be extremely fast and good, no matter at what price point. Thanks.

Marten Logan Decent I's are the fastest subs I've heard, but certainly not the best. Your the first one I've heard that think the Minimas are fast.
In response to Inna, i have a pair of Sonus Faber minima, and a pair of Ocellia Kedros (with PHY single driver). As for amplification, I have an EAR 859 with the Ocellia, and a preamplifier DeHavilland + EAR 509 MKII monoblocks with the SF.
Not familiar with your set-up, but yes why not try pair of good Rels or as some recommend a pair of JL Audio ? JL would be more expensive, right?
Wilson Bensch Torus, possibly even better if you use an ICEPower over its own amp.
