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

I owned Maggie 3.5Rs, I have 2 SVS subs, an Ultra and a Pro. I tried dam near everything to get them to blend, including active XO and BOM- another active device

I gave up, sold the 3.5Rs and now selling the subs if anyone’s interested
I have heard that REL subwoofers are good with maggies, and open baffle subwoofers as well. BTW, you can do a search about magnepan and subwoofers in this forum and see a lot of older posts concerning your topic.
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.
