VMPS Subwoofer Purchase

By the way I have no affiliation with VMPS, I just love their subs!

Just saw a used Brian Cheney Signature Edition (BCSE) VMPS sub in Rosewood:) on the Tucson CL. It's beautiful, hope someone close snags it!

Got the sub last night and it was actually a VMPS Dedicated/Smaller Subwoofer. Drivers and surrounds are in perfect shape. I'm in no hurry to upgrade to the megawoofers. I tuned the putty on the passive radiator and still experimenting with placement, but this thing sounds too sweet with the Focal monitors. -
Eric- told you I was going to do some research... now you have me intrigued on our deal. Been reading threads on audiocircle and other sites before I found this one. Which VMPS were you specifically offering and if it's very early how's the PR, links to replacement ect...
Guess we'll talk on the ph in the next few days and see if we can't put a deal together.2-ch System: Parasound P/LD 2000 pre, Parasound HCA-1000 amp, Parasound T/DQ Tuner, Phase Technology PC-100 Tower speakers, Technics SL-1600 Turntable, Denon 2910 SACD/CD player, Peachtree DAC iT and X1asynchorus USB converter, HSU VTF-3 subwoofer. -
The sub I offered to you is this one:
VMPS 215 (a 15" woofer and a 15" passive radiator: -
Taken from the VMPS stite:
"A good subwoofer can greatly enhance the performance of virtually any music system: first by extending frequency response into the first octave (16 Hz - 32 Hz); second by generating much less harmonic distortion in the subbass and bass regions (200 Hz and below) than is typical of most fullrange speakers, which often produce tens of percent THD in that range; and third by reducing intermodulation and doppler distortion in the main speakers by relegating long wavelength fundamentals to a separate driver which is well suited to reproducing this most difficult area of the musical spectrum. The woofer fulfilling these functions should be reasonably compact, efficient enough and of low mass and inertia to match all main systems, and not prohibitively expensive. In all these areas the VMPS Subwoofers excel.
There can be no clean first octave response from any speaker having a pronounced system resonance in the audible range, and the VMPS Subwoofers, like their full-range multiway siblings, are free of such anomalies throughout their operating region. This is achieved by means of a push-pull arrangement of active drivers and passive radiators. The mass- loaded passive, pushed by the low-resonant active woofer, provides most of the first musical octave thanks to its high compliance and a resonance frequency below the audio range (8 to 12 Hz). Another benefit of this arrangement is high efficiency, since front and back waves are utilized to produce sound, so typical subwoofer sensitivity reaches 89 to 92dB for one Watt input. Last but hardly least, the active/passive setup lowers bass cutoff to into the teens and early twenties, particularly when the optional high power, 80oz. stacked magnet woven carbon fiber Megawoofer is installed. VMPS Subwoofers are avoiding high moving mass (up to several pounds) of many competitors and thus offer flat frequency response to 300hz and higher. Electrostatic and other dipole radiators can therefore be crossed over in the more advantageous 175 Hz to 250 Hz range to minimize frequency response errors caused by the dipole effect (which in many planar systems starts as high as 700 Hz). VMPS Subwoofers reach undistorted output levels (for 5% THD) of 112 dB to 115 dB/1m and higher at frequencies much lower than other designs. Because of very low moving mass both of the active and the passive speakers, VMPS subwoofers are extremely quick and responsive, fast enough not to lag behind even the lowest-mass electrostatic or ribbon transducers now available."

I wonder on the recent passing of Brian Cheney and then the closing of VMPS will affect the sourcing of replacement drivers?

I'll need to talk to you about how to integrate it into my existing system, but it looks like a great performer. Does it have the upgraded woofer?2-ch System: Parasound P/LD 2000 pre, Parasound HCA-1000 amp, Parasound T/DQ Tuner, Phase Technology PC-100 Tower speakers, Technics SL-1600 Turntable, Denon 2910 SACD/CD player, Peachtree DAC iT and X1asynchorus USB converter, HSU VTF-3 subwoofer.

You just need to power it with an amp of some sort as unless I am off none of the VPMS are powered subs. With that said if one ever pops up in my area.... yeah all over it."....not everything that can be counted counts, and not everything that counts can be counted."

Yeap it has the "Megawoofer" upgrade. -
I bought a used older model Larger vmps sub similar to this one but mine didn't have the Megawoofer. You will love this sub, the look of the lite oak is like a fine piece of furniture ,it's beautiful .

I sure do miss this sub. It is an extremely rare occasion when I regret letting something go and this sub tops the list. That one sub trumps the two subs I currently have, in spades.

Been thinking about selling this sub and after reading some of these posts while doing research for pricing it puts me on the fence. The 215 is certainly the best sub I have ever heard even underpowering it. My room and setup just makes trying to get the most out of it difficult for now and the foreseeable future.

LOL, travis and I have talked a bunch about this sub. I just dont have the ability to use it right now or it would have never hit the Flea Market to begin with."....not everything that can be counted counts, and not everything that counts can be counted."

Oh yeah, I'm interested. PM me if you wish.
