Thanks for all the suggestions. As BMS got so many mentions I went with them and got some 4524's. I set one up on some cheap eminence horn, probably not the best to try but I have a couple spare, and put it on a pile of half finished projects in the garden.
I included a roll of gaffa in the shot to give an idea of size (and point the horn down a bit). It really is quite a small driver.
I had a listen with various music and I am really impressed with it. I have never heard a compression driver sound like this. It's got the top end of a decent bullet and is unbelievable smooth, not a hint of harshness anywhere. I didn't have the equipment on hand to try any eq so used the cd horn eq on the cheap berry crossover, and this did seem like more than was necessary. A quick play with the ultradrive should have it sounding superb.
It's a very efficient driver, I had it on a 75w/4r amp and hardly turned it up. When I did crank it it got too loud too listen to at a few metres but still sounded great.
Time for the next project, diy hf horn.

Bms 4550 Compression Drivers For Mac
May 29, 2008 What do people think about a BMS 4550 compression driver with a BMS 2230 horn, with a crossover point at 900Hz, on top of two half MT 122 loaded with B&C12PE32? (I mean to build the MT 122 in three different cabinets, 2x12' + the top section).
