REL Vs SVS for 2 channel music listening

Good to see Hsu Research mentioned. SVS is terrific. 

One not mentioned is Outlaw Audio. If you haven't already, you may want to check their subs out, especially if price point is a driving force.

I've had mixed results with subs. When done well, you will not know they exist until you remove them from the mix. Note that is subs with an s. 

Not sure if you want take the passive sub way. : )  Mentioning it as an option, since it hasn't come up.

I'm with @contuzzi @ricred1 @crwindy on the JL Audio. More musical.

But likely out of the OP's stated budget unless he/she can score a great deal used.

+1 regarding @crwindy 's post. Less is more. 

Since you seem to be leaning SVS, I second @yogiboy  's recommendation to go with the discontinued SB12 for $400. I'd double up. If you are going with one sub, then the Outlet PB-12Plus in Piano Gloss (with no damage) for $999 is another option.

@dlcockrum  and @aberyclark 

Any thoughts on the Longbow wireless delivery system vs using the Speakon wired connector?

@aberyclark   Great on making the choice. I'd add a second sub when you are able to do so. 

@chisaz  Don't forget the mouthwash! : )

+1 on you post! Enjoyable read, to boot.

I’ve been missing out, a lot.

Try an REL, you’ll be shocked (in a good way).
