Hi I have Magnepan 1.7s... originally I had a Rel T7 sub paired. Honestly, IMO it was just ok and I was wrestling with a love/hate relationship with the Maggies. Then my Rel blew a Diode.. so while it was down I quick picked up PSB subwoofer cheap. Crazy as this may seem.. the PSB pulled everything together. My sound never sounded better.. for all genres of music. I fixed the Rel, sold the PSB and immediately regretted it... bought a new PSB and have been happy ever since & it keeps sounding better and better as it broke in. It matches so good with my Maggie’s that I’ve actually considered starting a thread on it... I think other Maggie owners may be interested. Just another thing to consider.
good luck!
