Best musical sub under $1k?


I’m looking at subs under $1k. My mains are KEF LS50 Wireless. The room is about 12’x15’ and the KEFs are on a desk. The sub would go under the desk which is fairly open underneath. I’ve been looking at the SVS SB2000, even the SB12 NSD which is available well under $1k at $400, the REL T/7i and the ML Dynamo 700w sub. I don’t want anything physically large so the HSUs are out.

Thanks for any input.

Thanks for the replies,

Yes, the SB12 NSD does seem like a steal at $399 shipped. I think the SB2000 might be too much for my needs and I can get the SB12 for less than a SB1000. I just want something that can help the KEFs a bit when needed and again, only for music.
Thanks Erik,

I’m a big HSU fan. I have a VTF-3 MK 2 in my family room. I need something physically smaller, under 14"ish H/W/D, and I don’t see any HSU offerings that size.

I just bought the SVS SB12 NSD for $391 shipped so I’m going to give it a shot. It seems to be a good fit for what I need and the price was excellent. I got a smokin’ deal on the KEFs too so I’m a happy camper.
If you want a real sleeper the old Yamaha YST-SW160 or slightly better SW-305, they are musical subs, that have definition, not HT boom boxes, though they do have a boom (HT) switch, should you want to use it. 
And they are the perfect height for two ways to sit on.
They use twin 8" in them with linear amps, and are also servo controlled, tight, dry, very punchy and go quite low, enough to cause ear concussion.
