Musical subwoofer under $2000

I’m looking for advice on what vendors to look at as l’d really like to add a subwoofer to my 2 channel setup. The room is c. 30x15 feet or 42 square meters with low ceiling of about 7.5 feet or 2.2 meters. Budget is c.$2,000 and my 2 channel speakers are Sonus Faber Sonetto VIII. My amp offers pre-out connection. I’d like REL but their S range is now too expensive, so something close in musicality would be great. 


I’m using two Rel, T/7x with Magnepan 1.7i speakers and they work amazingly well in my large room. I started out with just one, which sounded very good, but adding a second one took the bass to another level. They blend so well with the Maggies, that you can’t tell your listening to subs. They’re fast & tight & keep up with the speed of the Maggies.  I personally don't see the need for the Rel S series. 

Here are some videos from Paul McGowan of PS Audio, giving his take on connecting subs to amp outputs vs pre-amp outputs. Also, his take on one vs two subs.

 To everyone who has responded to my search for advice I cannot overstate how grateful I am for all the links, personal experiences and knowledge being shared. I don’t know if it’s making the task any easier as it looks like there are so many options to explore. The audiorusty link to the sounddoctor articles is eye opening and thank you soix for your insights.


Look used for better value.  There is an ad here on Agon for a pair of S/510 for $2,700.00 (located in Chicago).  I know, above your stated budget but maybe you could up the budget a little bit and make an offer.  Then you get two of the subs you want!
