wide band midrange
 
I would like to have your recomendations for a very wideband midrange, with cross over I like it to be used in the frequency range from about 200Hz to 6-9 KHz.
I prefer, paper, glasfiber and kevlar cones.
Also it have to make 92-93 db sensitivity for a 8 om driver.

I have looked at Audax PR170M0, many must have used that already, or some of the other 4-6" sensitive Audax drivers.
How does the Audax PR17 series sound unfiltered?, is it agressive, nasal or open with out hardneses, I hope for the last. the upper frequency response becomes a bit bumpy, but maybe it does not sound like it.

Better it is a bit dark sounding that screaming!

I used FF125K with success

I have seen the audax used in a few high efficiency 3 ways, but havent built a system using it. Perhaps one of tangbands fullrange drivers would suit? Or perhaps visaton B200 or FRxxx range of drivers? What box type you are making will have some impact on what best suits you.

Thanks for input. The smaller Fostex fullrange drivers can nok make the 92-93 db sensitivity right?
I would love to hear from some that have used the audax midranges.

NOK? If you ment "not" make 92-93 dB, I believe that there are several in the 4 inch diameter size range that actually do produce that level of efficiency.

I always thought the current crop of super Full-rangers would make for outstanding mid-range drivers.
Consulting the specs, most all of them have a rather high Efficiency Bandwidth Product......putting them squarely in the Ported enclosure class.
That said...where would you put the port???
Would there be problems with two ports on the front of a baffle?......One for the woofer, the second for the mid-range.
I can imagine some interference/nulls/distortions with the two ports interacting.
With the hyper accuracy of these full-rangers...one could make a superior system......with the voicing of the Mids being the best possible.

To get the kind of efficiencies specified FF165 is closer.

If he is looking at 200 Hz XO, why would he use a port? Sounds to me like sealed box is the way to go. Or is there something here that I don't know?

Cheers, Jim

lots of good stuff here. have you considered a dynamic in a large straight horn?
Best regards Moray James.
