1" compression driver/soft dome

[Hylle]

Like many of you guys, I would like to try a compression driver, in sted of my soft dome, whitch i normally prefer. With that in minde. What compression drivers/horn will you recommend me. I am holding a bit back on the metal cone types (that is most of them).
I am also sceptical about long horns, i am think they will sound nasal.
Let me hear some oppinions from someone who have tried this.
I does not have to be the most expensive types you recommend :-) It will have to be used from 2500Hz and up.

A treble horn will be very short. 10 to 50mm long.
A mid range horn will be longer. Generally <500mm long. A 300 to 400Hz horn would approach this length.

Where do you find nasal sounding long horns on compression drivers?

Easy, cheap decent performing flare would be the 18Sound XT120.

There are a lot of great Euro drivers from B&C, BMS, 18Sound, RCF, Faital Pro and Beyma. I have a fondness for the mylar diaphragm units from B&C like the DE250 and the Beyma CP380M

bms 1inch

1kHz up to 30kHz With short horn.







The set about 150 euro. one of the best and low priced.


This one 4524 also very good up to 20kHz set 60 euro!

Another option.

Monacor DT300 with horn.

I'm becoming quite impressed with the B&C DE10. A great bargin. Not as good as the DE250, but about 1/2 the price. The DE250 is so efficient that it needs a good woofer or a huge pad to its output. The DE10 is a better match to a lower efficiency woofer or midrange.

I am fond of this one:

nice clean csd and freq response - the chart is unsmoothed

would a high efficiency treble driver be an ideal candidate for a nice ClassA amplifier?

I have both DE10 and DE250, the former best x-over above 2.5KHz the the latter cross above 1.7Khz.

Both sound very good and not a hint of high freq. zing to them. Also both are dynamic, and of very good value.

One needs more than just axial response to sort out a good driver. That said, I find the waveguide dominates the polar response and in general the waveguide will dominate how it sounds. I just look for a decent sensitivity match and price as almost all compression drivers, to me, are about the same (the waveguide being the dominate factor).
