At the $800 to $1500 used price range, I would recommend the Bag End Infrasub 18" subwoofer first. Extremely tight and musical sub that faithfully reproduces down to 8Hz. Not many subs out there can even go down to 20Hz much less 8Hz. You can find a used one here usually for about $800.
Next would be the Triad Platinum 18 inch sub. Musically just a step down from the Bag End.
I've auditioned the Bag End for several weeks and really enjoyed it's presentation. I had no idea a sub, especially an 18 inch sub could be so tight and yes musical.
I ended up going with the Triad Platinum because it's sonic were also quite good but it had a few more configuration bells and whistles.
The REL subs are supposedly highly rated but they are typically in a higher price category.
The sub is the most controversial component for music systems so get ready for many varied opinions.
