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.

Selenium D250-X GW 1" Phenolic Horn Driver 1-3/8"-18 TPI

Would it be possible, or advisable to parallel a piezo tweeter off of these to extend the frequency range for use as a midrange cabinet driven by a dedicated amp and used with an active crossover?

Asked by: TLM7
There's nothing wrong with doing this. You will have to play around with the number of piezos that would match the output of the mid the best.

I am building a bi-amped system using an electronic crossover. I am thinking of using these horns for the midrange/tweeter speakers which will be driven by their own amp. As these only go up to 9000 Hz, what can I parallel off of them to extend the range

Asked by: TLM7
You will not want to parallel these with another different driver, these will need to be used on their own as a dedicated midrange and a separate tweeter will be needed.

will a 1,647khz crossover be fine with the horn driver?

Asked by: samy boy
Yes. low response is 400Hz with a recommended crossover of 1000Hz and above.

What is your opinion to using it for a 375hz Smith Horn? Also since this is thread mount, is there an adapter made for the threads to mount it?

Asked by: Jetwave
The lowest crossover point that is recommended for this driver is 500 Hz. If you need something to play as low as 375, you might consider something like the Dayton D1075T, which has a 16 ohm bypass and can play safely down to 300 Hz. We do have thread adapters available, but only for standard 2 or 3 bolt mounts.

How do you avoid distortion?

Asked by: Bradman
As long as you do not exceed the power rating of the driver, clip the amplifier and use it within its safe useable pass-band you should not have any distortion issues.

I'm building a home theater system and going to use this driver for the center chanel (voice). I tried it with a cheaper driver and it's sick. My question is whats the best lens I should get? I think the largest I could find would give me better angle.??

Asked by: Guys11
The larger the horn the lower the driver will play, so it ultimately boils down to crossover points and the dispersion you would like to have for your intended application. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.
