VMPS 215 Passive Subwoofer $400 delivered within 3hr zip 37604

TNHNDYMAN

After much deliberation I've decided to let this awesome sub go. It will absolutely 007 any martini in the room when asked. Acquired this from Conradicles earlier this year and have enjoyed it for a spell, but need to make room for some other upgrades. Condition I would estimate as maybe a 7. It is older and has it's share of nicks here and there but nothing affects the performance. Grill in decent shape and the light oak finish looks good but could use some attention due to some fading. It is a beast at 28W X 20H X 17D and 95lbs. I have the original packing box but feel that shipping would make other options a better choice due to cost. I am willing to drive 2-3 hours from zip 37604 to meet the buyer. $400 delivered. This has the upgraded 15" megawoofer. Feel free to PM with any ?'s or to discuss on the phone details for delivery, but please post any interest in the thread first in order to keep track of who's got first dibs. Thanks, Travis.

If someone would like to come pick up at my place, price would be $300.

What are you powering this with? Any idea on the bass extension? "How low can it go?!?" :razz:

Cody, here is some of that info for you :biggrin:. Note these spec's dont include the upgraded drivers so it might go even lower than these show. There is another CP thread that tracks the ownership of this sub on the forum, and has input from former owners. (www.polkaudio.com/forums/showthread.php?57891-VMPS-Subwoofer-Purchase)

Specifications:
Drivers = Original / 30 cm (12″) WCF Megawoofer bass, 215 / 38 cm (15″), both have 38 cm (15″) Passive Radiator
Rec. xover range = 60 Hz - 300 Hz
Internal wiring = 12 gauge Monster Cable
Impedance & Sensitivity = 8 Ohm, 90 dB/1W/1m
Power handling = 300 W rms / 4 Ohms, 20 W min.
Frequency response = 19 Hz = 600 Hz +0/-3 dB
Dimensions & Weight = 50H x 67W x 43Dcm, 43 kg (20″H x 26″W x 17″D, 95 lbs)
Output levels and distortion = max. 2.5%THD fullrange / 1 W, max. 112+ dB SPL/1m
Finishes = standard lite oak, dark oak

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.

Thanks for the help Dan. Yes it goes down to 19Hz. It produces bass that you really feel as much as hear. I had an Adcom 5400 on it initially and then tried the Rotel 981 bridged which did a better job of waking it up. Also used an Adcom 5300 but it didn't have enough balls to light it up. I would highly recommend going the route of a Crown XPS series amp for high and clean power to get the most out of it. You need to keep the amp away from the sub. I learned this the hard way when testing it with the 5400 on top of the sub. Stupid idea. It killed a channel due to vibrations not clipping- probably a solder joint somewhere that I've not had a chance to track down yet. Feel free to call me Cody or anyone else PM for more info.

Hello, EndersShadow and good afternoon to you. Those aren't the specs for this sub, FYI. The posted specs are for a VMPS Larger, which has an additional 12" woofer on the front.

This is true. This is the 215 with 1 active and 1 passive 15" driver. I still think I read from Conradicles whom I got it from on a thread here at CP that it goes down to 19Hz. Not really a big deal either way it goes very low and makes quite an impact as well as being very musical. Not trying to mislead at all, I have no way of actually measuring it myself. I'm confident treitz3 knows more about it than I do. Most of the threads where I found info on the VMPS subs when I originally considered it he was involved in. There is quite a bit of info avail via a quick google search.

codyc1ark

Hm. I'll have to get my google on, I've got no issues throwing some big power on it. However, I can squeeze a second into my room and have been thinking about doing that. I'll do some research but by no means let me stand in the way of a sale Travis.

TNHNDYMAN

PM sent to treitz3.

cody you should still have my # if you want to discuss, if not send me a pm a good time to call and I'll get back to you.

Darned it.... oh well, I had em stored on my email for some reason lol.....

Hope all is well Tom with you and yours!

Conradicles

Actually just to clarify, the above specifications of the VMPS 215 sub are correct all for the "Drivers = Original / 30 cm (12″) WCF Megawoofer bass". The VMPS Europe website had a misprint.

The VMPS Larger sub had specifications of:
4 ohm, 92 dB
17Hz - 250Hz +0/-3dB
23" x 32" x 19" @ 138 lbs

Both are amazing.

Still waiting on a call from Treitz3. Still available.

Good luck on this one Tnhndyman, for anyone unfamiliar with VMPS, they make quality equipment and the outer enclosures are constructed of well crafted wood . I have one of the VMPS Larger sub and it looks like a beautiful piece of furniture in the room.

Oh hey! My apologies. After dinner the other night, I passed out on the couch and woke up there the next morning [ah, the pleasures of working your arse off]. I am going to pass on this one. What I am looking for is specifically the VMPS Larger. Two of them, actually but I will wait on them, as I have the massive crossover project I am working on right now to complete first. In fact, I'm dropping off the Tyler Acoustic speaker cabinets right now to be professionally refinished/reconditioned or reveneered. So with that said, I will pass on this great opportunity.

Question -

How important is the location of a sub in a listening room?

My instincts tell me it should be centered, and my first thought is right under the listening couch.

But I wonder if having it up front and to the left of the left speaker would be OK. Again, instinct tells me no, but...

Thanks.

TNHNDYMAN

No problem Tom.

Placement makes a difference but there are many threads out there to determine the best placement for your particular listening space. That being said, the size of this one limits options sometimes. Some people get good results from placing the sub in a corner of the room then crawling around the room to determine where it sounds best and then moving the sub to that spot. YMMV

Bass is omni-directional.

Room correction on the other hand it a whole other can of worms...

Polkie2009

I've used the method of placing the sub where the main listening area is and then crawling around the room listening or taking measurement with db meter. Room size can make all the difference in the world, especially if you're trying to get the most output of this sub for HT. Being a sealed sub , this usually gets better bang in rooms with less cu. ft. Corner placement might get you the most bang for you. YMMV. For 2 channel listening, put it where it sounds the cleanest. +1 agree with tn, there are many__ threads here that focus on this very subject.

stretchl

Room is about 19x12. I wonder if my Adcom GFA-555ii would power it...

treitz3

Hello, stretchl. Yes, it will.

Tom

TNHNDYMAN

Stretchl- Are you coming to TN soon or are you just dreaming? I've been through Champaign a couple of times and it's a lot farther than 4hrs away from me. Shipping this puppy would be expensive at least and probably would be best done on a pallet and strapped down. It's possible just not cheap. I won't make money on shipping it, but I won't lose any either.

TNHNDYMAN

My intention was not to kill any interest, just being realistic. I'm all up for the polk pony express and will drive it 3hrs in anyone's direction and hand off if we can line something up. Feel free to PM for contact info and I'd be happy to discuss further. I would be willing to drive it even farther if someone wants it bad enough, but I'm going to charge for gas and a room overnight if I drive over 5hrs one way.

TNHNDYMAN
