Best subwoofer for music under $1,000

I have had several brands including Velodyne, Emotiva,Klipsch,
And by far the most musical ,is he sealed 12 inch sub from SVS
They use a 400 watt Bash amp with peaks up to 800 watts.
The driver is a heavy duty 12 inch Aluminum driver from Peerless.
For $649 , it is excellent for music very tight and tunefull Bass,also very good for movies it digs down deep very respectable
This sub will go down to 23 hz , if you want more boom then get a ported design .this sub is very respectable in anything you through at it
And they have great customer service,as well as a 5 year transferable
Warranty. P.s if you buy 2 subs you save one decent moneys,
And you can trade up to a more expensive model within one year,
And they have at least a 30 day trial period where you can send it back .
