Anthem Perfect Bass Kit vs. Velodyne SMS-1

Is this system dedicated/proprietary for only Paradigm subs? I did some reading up on this when I was considering purchasing an Anthem/Paradigm setup - sounds like it's a great system.

I am nearly ready to pull the trigger on a Velodyne SMS-1 bass management system, but the PBK system would be far less expensive, as it is basically a microphone and some software for your computer.

If it's proprietary to Paradigm subs, then it's a no go for me. But, if you can use it on any sub, has anyone compared this to the SMS-1 system?

Thanks. I'm in Canada and that's in the US. I have found a used one here in Canada for a reasonable price. But now considering whether I should just bite the bullet and step up to the Denon 4311. I will be in need of more channels for multiple zones, although not an immediate need. How far out such a purchase could be will determine whether I go for the SMS-1 now or not.

Then there is also a thought in my head that I should just chill for a bit and enjoy my system. It's not a dedicated room, so the bass is not a super key item right now, probably.
