Vandersteen Sub woofers v Rythmik Subs


I really love the idea of the Vandersteen Subs where they are connected with the mains via extra speaker cable off right and left channels off the main amplifier, which is supposed to provide better bass transition from the mains while keeping the signature from the main amplifier. My question is with Vandersteen coming out with the SUB THREE and the price going significantly higher, I was wondering if there are other subs for less that you could integrate in the same way. (Most subs seem to rely on the line level input which is just a sub-woofer RCA going from the pre-amp to the amp on the sub). Can this same Vandersteen set-up be achieved with other subs?
I picked Rythmik since they are known (in the home theater community anyway) for being one of the best bang for the buck subs and the most "musical" of the bunch. (between Hsu, SVS, PSA).
And could I possibly achieve even greater sub-woofer nirvana since I could get an 18" for around $1500? Vandies only have 3 eight inchers.

I am a Vandersteen fanboy and I would like to support RV whenever I can, but don’t know much about my other sub-woofer options so looking for some feedback. Doesn’t even have to be related to Rythmik necessarily. If you know of other subs that can integrate the same way I want to know about it!

Not really. Rythmiks also have the connection to feed off the amp taps, have phase and Q adjustments. But having more variables, hence options, also introduces more uncertainties, which is why sub integration is such a difficult task especially if done without measurement equipment

Ahh ^That^ is interesting.
The Vandy line is designed to be in phase all the way down… So I was concerned that some other sub could be way out of the “driver’s acoustic” phase.

I have heard of the rythmic method before. Maybe it was in one of @tubebuffer  posts?

I have an older Vandy 2<something> subwoofer, and it seems to work fine.
