There are some NOS m11wg on eBay so I picked up a pair cheap. They have arrived today and look pretty nice.

I haven't been able to find much on these in terms of designs though, anybody has first hand experience with a) how these sound and b) how these measure and behave?

Side by side along with rs125s






Thanks!

Dug up a blurry datasheet for you.

Looks like your typical flattish 4-5" midwoofer. Suitable for midrange duty too. 4 litres closed box. 5.4R Re and 0.6mH Le is fairly typical too. I'd think most small designs for regular drivers would work with this one.

What do you expect from a tiny 125mm driver? 🙂

You've got nearly an identical ScanSpeak 12W/8524G00 driver here, except for the bass loading:
Discovery-12W

Shame Troels is all coy about crossover values on his recent designs. I think you could adapt the Ellam-XT to your purpose. You know the notch goes at about 1.3kHz.
