magnapans.7i and subs


so i am looking to ad in a couple subs. my magnapan dealer likes paradigm subs and has suggested the defiance x10 specifically. upon reading about this sub it is ported. i have always assumed sealed subs are suited better for 2 channel listening. just wondering if anyone has this setup or has experience with this particular sub

Check the specs before you buy, some subs  don't really go that low. It will depend on the music you listen to I guess.
Hi,
I have a pair of .7's as well and I run a pair of REL t5i's. I also have a pair of Heresy II and a pair of open baffle Caintuck Betsy's with the LII Fast 8 drivers which are super fast! I use them all with the REL's and they too are super fast! Once you work with the cross-over and volume adjusted they really open up. All I did was make a few adjustments and sat back down and listened, then I got back up and made more adjustments. Once I got the feel of it, they blend perfectly with all the speakers. It's like they're are not even there, but you feel it during certain times in the music. I got mine at Upscale Audio. I mostly listen to two channel jazz but sometimes when you hear soundtracks, the impact is felt in your chest. For example my wife downstairs was getting scared because she heard a low sound but didn't know where it was coming from. That's because I was playing sound tracks from Batman Begins and Hans Zimmer. When I play jazz, the bass is super fast, tight and controlled, not mushy or boomy. 

The other thing I really love about the REL's is the way they connect which is unlike anything else. Not only that, but the build quality is really nice too. 
I have listened to the 3.7i's with upscale Rel subs, and it sounded wonderful. Another choice of subs would be Vandersteen Sub 3's. Although they take a bit more ambitious amount of implementation.

@johnnyaa, the statement above that REL subs connect "unlike anything else" is incorrect. Rythmik subs also provide for "High level" connection (from the main power amp, on binding posts), but unlike REL's offer the alternative "Low level" (from a pre-amp, on RCA jacks) capability, allowing one to try the sub both ways.

The Rythmiks also sound excellent, with 12", 15" and 18" models available. Quite a few Maggie owners have posted on the Planar Speaker Asylum about the mating of Rythmiks with their planars. A VERY special sub option is the remarkable Rythmik/GR Research OB/Dipole Sub, which blends with planars like no other sub available. Read all about it on the GR Research AudioCircle Forum.
