Or possibly mid bass driver, but no bigger than 4" overall diameter.
Something like a Vifa M10MD-39-08 will be ideal.

Freq range required is approx: 300Hz - 4KHz.

After only 1 driver.

Does anyone have anything like this, or can at least direct me where I can find one, new (preferebly) or used?

Thanks.

I assume you mean the speakers and not Wagners service. :)

I haven't used them yet. I bought a pair about four years ago based on their reputation of arguably being one of the best mid-ranges available but never got round to using them.

I recently found an interesting design for a bipolar transmission line (the TLB) that uses a pair of these speakers in each box. This project is on the list of things to do but because these Vifa speakers are listed in a lot of places as being discontinued I thought I should get them whilst I could.

The original pair I bought are labelled as being Made in Denmark but the new pair are labelled Designed in Denmark. However they look identical and the TS parameters measure the same.

I have a spare 4 ohm vifa p11 (cant remember model #) in new cond You can have for $20 + freight.

It has a higher q than the 8 ohm but just means mid enclosurevolume may need to be a few litres bigger.

I use them from 300 to 3.2k between a hivi d10g(-3db 23hz!) to a hivi 1.3 ribbon. Sound great to me.

I bought 4 off a guy who bought a heap of them for open baffle line arrays and had some spare. I believe he bought them as excess stock from vifas distributor years ago, used one each in my L/C/R (centre has 2 hivi d5g instead of 1x d10g) and now have one spare. I dont have the data sheet anymore but the response curve was more or less identical to the 8 ohm.

Let me know

No I meant it's a link to essentialaudio, an aussie based shop that sells drive units.

They happen to sell the TC9FD-18-08 that Ed mentioned earlier on.

Full Range

Zaph has measured these and found that they have remarkably low distortion, that and a smooth and extended frequency response. There's not really much else you could ask for of a small driver, it's price is simply a bonus.

lunchiety, are these the ones that are coated and designed for free space mounting with fs of 168Hz? give or take a cycle or two. if they are i probably sold them to you. i bought out vifas distributor stock around 2002/03. i may even have a few in the shed still in the vifa poly packs.

If you're still looking I a pair of these:

Vifa PL11WG09-08 4" Woofer - Description

Vifa's PL Series incorporates several new technologies that were developed with the goal of lowering distortion and increasing self-damping in the speaker. The coated paper cone reduces vibration and standing waves, and the vented motor system minimizes power compression. The combined result is a very open and dynamic sound.
Specifications: *Power handling: 80 watts RMS/140 watts max *VCdia: 1" *Le: 0.61 mH *Impedance: 8 ohms *Re: 5.6 ohms *Frequency response: 69-5,000 Hz *Fs: 69 Hz *SPL: 85 dB 2.83V/1m *Vas: 0.15 cu. ft. *Qms: 2.2 *Qes: 0.6 *Qts: 0.47 *Xmax: 3 mm *Dimensions: A: 4.92", B: 4", C: 2.3".

They aren't efficient enough for the speakers I built. I'm looking for a pair of 4" in the 89-91db efficient range. And in looking for them here found this thread.
