This is an amazing deal for a very capable sub. I'm a home theater enthusiast and I don't think I've ever seen a better value! Hop on this now before the inventory is cleared! I already have two monolith 16s, but now I'm about to pull the trigger on two of these as well. The price is just too good

I have a 12" monolith and trying to move and position that thing alone is almost impossible. I couldn't imagine trying to move one of these around lol.

I wonder if it's time to sell my dual SVS PB12. This one may actually be able to replace both?

I just bought a PB-2000 Pro for SVS president's day sale.

This is way too good of a deal to pass up. In for 1. Thanks op.

Same setup here. Can probably sell the SVS pair for 600-700. I just dont know how much of an upgrade it will be.

I've got dual 15" monoliths now. Think there'd be any issues adding this?

Outstanding price. Just realized if that amp goes out after the 5 year warranty, you'll have to power this with an outboard pro amp. I had a hell of a time finding an amp for an SVS Dual 12" that was well out of warranty. SVS didn't make that amp any longer and being 900 watt, and a specific size, needed major adjustments to the cabinet for a plate amp. Mine was only 145lbs. Was amazing while I had it. If you have the cash, enjoy this. It will rattle the house.

More barely used user accounts talking about how they own multiples of these products and how they're the greatest deal known to man. Same in the Monolith mini-tower speaker thread from today.

Triple same setup here! Yeah not sure if the extra 8hz of extension is worth the upgrade and of course the hassle of selling the svs subs

Damn it would have to go sideways in my setup, I wonder if that's not ideal

Agree. Nervous about going from dual to single. I've never heard this one but I can't help but think it packs a punch. I have a fairly big room to pressurize. 375 sqft with a 9 foot ceiling. The PB12 do ok. But you still don't get the chest punch.

My sweet spot behind the screen only allows 26 inch depth so this would have to fire sideways at the outside wall most likely.
