Hopefully we'll see dual 10's or 12's for subs from Bryston or perhaps a single 15" sub.
Have been thru JL F-113's,Velodyne DD-15's.
My used 1812 gives so much musicality to music and and impact I was in disbelief when I first listened to it.
They are in high demand if you can ever find one as they are discontinued and have been for a few yrs.
Besides the above subs have listened to JBL folded W bass bins and the 1812 just takes everything to another level.
Had 4 JL's and the 1812 made them sound like an unmuffled over toned kick drum and that's no matter where I moved them inch by inch.
She's a monster in at 385 lbs and about 4' tall and what I have heard for subs so far nothing has touched it so far,
perhaps that's why they DISCONTINUED IT and it in HIGH DEMAND.
to bad she's so big
