This is probably the wrong site to be listing these but I figured I'd give it a shot.
I have a pair of Vifa M22WR-09 08 midbass/subs for sale.
1 is in good condition while the other had it's dust cap pushed in and pulled back out, it looks a bit rough but both function 100%.
I did some research and found that these drivers are being used as subs in some pretty off the wall high end home audio Reference speaker systems. These are currently on the market overseas @ 142 AUD each.
I am taking best offers for the pair as it seems I am getting conflicting information with regard to actual retail pricing and production on these. 1 member was kind enough to point out the fact that these are indeed discontinued and there is supposedly a surplus or overstock on Ebay. (That I have yet to see for myself)
I don't know what TS parameters mean, but I found some specs on these, they are listed below. These are specs found on the site of a retailer, not sure how accurate they are, you may want to do some more research.
According to the site I found, they are designated as subwoofer/midrange use. In some of the descriptions I read, they are met with rave reviews from DIY guys over there in Europe.
I never used them as midbass but had tested them in an enclosure that was suited for use in a subwoofer application. They sound excellent, very impacting. They took what my Adcom GFA-555 had to offer in total stride, no ill signs of distress.
Description: 220 mm woofer with heavy alloy frame, ultra stiff treated conical paper cone and wide rubber surround.
Nominal impedance Zn (Ohm) 6
Reference voltage sensitivity (dB) 88
Voice coil diameter d (mm) 50
Voice coil length h (mm) 21
DC resistance Re (Ohm) 4.3
Voice coil inductance Le (mH) 1.1
Resonance frequency fs (Hz) 30
Mechanical Q factor Qms 2.73
Height of the gap hg (mm) 8
Electrical Q factor Qes 0.38
Total Q factor Qts 0.33
Long term power (IEC) (W) 15
Xmax peak (mm) 6.5
Moving mass Mms (g) 36.00
Nominal power (W) 200
Effective piston area Sd (cm²) 224
Equivalent volume Vas (ltrs) 55
Force factor BI (Tm) 8.8
