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!

Thanks

I loved those Quads. I will never forget hearing them for the first time.  It was an eye opener.  I also remember falling in love with a large Maggie panel back in 1991 or so with my EX in Newport, RI if I recall.  Then the Apogees in the mid 90's.  Funny as I don't like the Martin Logan stats.  
ctsooner,

I completely agree with you on loving the sound of the Quads, large Maggie panels and the original Apogees.

Interesting that all of these ’fast’ speakers share the common complaint from owners that they’re all very difficult to integrate subs with. The usual complaint is the sub or subs sound disconnected from the main speakers because the ’slower’ subs cannot keep up with the speed of the ’fast’ panels. I currently use a pair of large Maggie panels in my system and tend to agree with the difficulty of integrating subs well with them.
However, I would definitely suggest the Audio Kinesis Swarm,Debra or any custom 4 sub DBA system as an excellent method of seamlessly integrating a sota bass system with any ’speakers but I can verify they integrate especially well with ’fast’ panels.
Because each Debra sub has a 10" long-throw woofer and is only required to reproduce a portion of the total bass, I think each sub is capable of being very agile and, with all 4 working in concert, it results in bass that is very articulate with great definition.that can reproduce the entire range of bass notes incredibly accurately; from very deep and powerful to sharp and taut.
     I believe anyone listening to any DBA system, whether an Audio Kinesis complete kit or a custom system of someone’s own creation, even briefly would be able to quickly recognize the extreme quality of bass reproduced but it’s much harder for me to express in words.

one issue is bass is directional above 150 HZ so subs that have much output above 150 HZ , especially those behind you ( in the corners, typically four corners..mess up spatial phase information
so you can trade away that for smoother bass...

for those with digital room correction, IF you rerun do the settings change ? IF so, why ? averaging algorithms? sample weighting, sample stack ? ambient noise ?
for grins, run the RTA w no music on and see what is happening in the room...AC cycling, freezer, trash truck out front.....you will be amazed....

Apogee stages, very fine CT but I guess you and I have shared that story before...
also for grins...just play your subwoofers by themselves sometime.....not on anybodys platinum album list..ha
yes we have had that Apogee discussion, lol.  Those little Stages for the money were money, lmao.  The only subs I liked on Apogees were Apogees. lol.

To my ear, it doesn't matter who's subs you are using and what size they are, they just don't mate with the fast panels I've heard. When you speak about subs with anything above 150hz, I totally agree.  they need to be crossed over in the 100hz range or so.  It's not hard to do.  With larger panels I honestly, don't mind just using the bass they have and letting it go as is.  I"m sure that I'll get to hear Richards new Sub 9's on the large Maggies.  They are fast as heck in the way he designed them, but like the AK's that I haven't heard, I can't comment until I have.
