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!

tim - it looks like you missed a few decades of Vandersteen innovation since your speaker shopping experience with now long discontinued model 4

yes Vandersteen has always been about frugal value many of the products ( which you can still buy in upgraded version today ) have risen less than inflation ( Model 1ci data available on a recent thread ) perhaps you have run a business and did better that inflation... I can say having run a $1b a year operation it can be tough and requires constant improvement

i would say including Dick Hardesty that Vandersteen entered the ranks of the very best of high end with the model 5
which includes a magical push pull aluminum cone driver with patented honeycomb bracing - lots of crappy non pustonic drivers might even out frequency response but out of phase junk is distortion.
the 7 which you seem to malign ( have ya heard it ? ) as Uber expensive is with exceptions of Magnepan probably the best value in SOTA speakers
count me as biased, I own a pair and the monoblocks
look at peer group prices at Munich show and perhaps learn that $62k might be good value
did you by any chance take time to understand the carbon fiber and constrained layer cabinet in the 9 sub ?

finally Vandersteen are ruthless about driving advanced features and technology down the line to improve Sound in less expensive models
i get you love swarm, you are happy
enjoy the music !!!!


Also in the interest of full disclosure I actually own and listen to the extremes of the Vandersteen line - from $1,370 a pair Model 1 to Treo CT to the 7

have to say all quite musical and I sure enjoy music.....

peace

Ok math and physics

read the measurements in the reviews and understand that relative to most dynamic loudspeakers Vandersteen presents a rather benign load...

is it a perfect lab resistor? no

since we have established no tube amp transformer can drive any variable load, appears roughly half of the Industry and music zealots will need to take up bowling..

i worked in advanced technology business to 30 years - cool stuff based on math and science - satellites, rockets, missiles, helicopter, people haulers, ...
lots and lots of armchair engineers claiming we got it wrong... over those 30 years a few, scant few did have a better idea, some actually quite disruptive to technology and the industry ( think stealth and the math behind it )
but without the stones or capital or common sense to get it to market
( making $ even harder )

so so who knows, perhaps ....

but it since I am interested in better sound, I earnestly await ??????
When REL subs are connected to a main amp’s speaker outputs, they put a 100,000 ohm load on the amp, so 2 of them would seem to put a 50,000 ohm load into the mix...I haven’t noticed that any amp I’ve used with RELs has shown a tonal or performance effect from a REL being connected to it, so I doubt they mess with the amp in any way other than generally helping things sound better. Easy way to test this...turn the RELs down and listen to the amp...unplug the Neutrik cable from the REL (or RELs) rendering the load to zero...and listen again...hear any difference?
