Rel B2 or JL Audio f 112

REL B2 and JL both have high and low pass filters. Either product will extend low end of the Studio 20v5.

REL B2 implemented in my HT system and I have experimented with my two channel system.

Why not use a Paradigm Sub12,it's voiced to work with the Studio series.Just a thought.

for what the Sub would cost I would sell your 20's and look for a used set of Paradigm Sig 8's. Man, Paradigm makes such great speakers for the money.

If you really want a sub, I agree with TP, go with one set up to match your speakers. Paradigm makes great subs.

Shoot what am I saying, I own a Rel I need to tell you to buy a Rel.

LOL

Have owned 4 different REL subs, they are the best. Paradigm subs are not even close.

I love my Rel B1, I do think it's the best all around sub I have owned, and I have tried a bunch or them.

But Audiofreak, have you owned a Paradigm, and used it with Paradigm speakers? There really is something to be said about synergies with certain gear that was designed together.

I do agree about the Rel's though, they are super flexible, and extremely easy to set up. I finally set mine on an Auralex platform and I was shocked that it actually made a difference.
