Any decent sub will sound good. The trick with the maggies is to run the crossover as low as possible. I run mine at 50 hz with good results. If you run them at 80-100 hz the results are not as good. The problem you run into is in running a dipole with a monopole.
Maggies and subwoofers
I have a pair of Maggie 3.6 speakers. Has anyone found a good subwoofer to mate up with these? I'm considering two Vandersteens or 1 Revel B-15. I'd sure like to hear other peoples experiences, choices, or experiences. Thanks.
