Rated 5 out of 5 by from THE go-to mid horn driver!For high power, clear and loud mid-range, this is the driver. For screaming B3 sounds, this can't be beat. I use these exclusively in our high-end products and it never fails to drop jaws when people hear it.

Rated 5 out of 5 by from Best midrange ever triedUsing in open baffle with selenium tweeter, both feeding 12" round wave guides. Waveguides boost @ 6000hz, making a first order x-over possible to the tweeter. Easy 2nd order 500hz high pass via F MOD introduced no phase discrepancies and takes heavy lifting off tube amp. So smooth it need no low pass filtering! Absolute bargain. Stunned at how well this performs with dipole woofers. No need for notch filters, zobel networks either. Really amazed at this price level.

Rated 5 out of 5 by from fastJust what I wanted and I got the order very fast. I needed "fast" as I had to have PA ready for a huge show and I made it. Thank you.

What does "low distortion and extreme clarity in the critical mid or vocal range" mean?

Asked by: Bradman
Critical mid or vocal range are frequencies between ~500-3,000 Hz. This driver works best in that range offering low distortion and very good clarity.

Will a 300w amplifier power this horn driver?

Asked by: Bradman
Yes as long as you had a proper crossover added for protection.

Where can I get a replacement magnet for the rpd250x driver from

Asked by: SlickRick
The replacement magnets are not available by themselves, you will be much farther ahead simply replacing the whole driver.

Trying to convert a pair of 2-way Crate PE12H into a 3-way w/o any modification to the cabinet. Plan to replace the 12" woofers with Eminence 12CX coax drivers to add a 3rd driver. D250X to be used with the coax driver. Could D250X be crossed at 500Hz?

Asked by: Joosoof
Yes this can be crossed over at 500 as long as it is at least 12 dB per octave.

I was planning on building some big tower speakers with a 4 way setup design, but i cant decide what midrange. What has better sound quality (but some spl as well) a midrange woofer or a horn driver? Will play them from about 2 to 7khz. 

Asked by: leonveek
Better sound quality is subjective and impossible to answer. You can get good sound from either option, although the horn driver will probably require more crossover work to tame it.

Which 2 way crossover would i use with this horn driver? The driver will be used in a Leslie speaker build.

Asked by: Huboe
I am a little confused using this driver in a 2 way set-up. I am sure you are aware, this is a midrange driver. Even though the specifications say it will go to 9000hz, it falls flat on its face after 5000hz. If you are building a traditional 2-way (woofer/tweeter), I would return this driver and get a Selenium D220TI HF driver.To answer your question, it depends which type of horn you are using and your woofers performance. . The minimum crossover point for this driver is 500Hz and you can use a Eminence PXB2:800 with a Selenium HL 14-25 or HL 23-25 horn. Both horns are rated at 600 min crossover and you will be crossing over at 800hz. Almost all woofers will do 800hz no problem.If you got the wrong driver and switch to a D220TI, then we need to move the crossover point up to 1500hz. An Eminence PXB2:1K6 will work nicely with a Selenium HM 11-25 or HL 25-25 horn. Both horns are rated at a 1200 min. crossover. It will also work nicely with the above horns as well. Most high quality woofers will do 1500-2000hz, so depending on your woofers quality and performance, you should be ok. The D220Ti is good from 1500hz to 20,000hz.Hope this answers your questions.
