The driver’s small magnet diameter allows front mounting, making it easy to install without detaching the driver from the WG08-25 Horn.

Small 3.31″ x 3.31″ faceplate, takes up very little mounting space, allowing you to mount a compression driver between speakers.

Its design was developed to give custom doors a new solution for a ultra-small horn driver, this mids and highs horn driver possesses extraordinary sensitivity thanks to high strength neodymium magnet.

D275Ph-s 200 Watts Program Power | 100 Watts RMS | Frequency Response: 500-6500Hz

The specially designed Polyimide diaphragm provides durability and additional damping for natural sound quality.This driver is built to resist the elements, perfect for outdoor use. This technology raises the bar for high frequency drivers by giving the driver wider usable bandwidth for smooth, dynamic output along with excellent efficiency.

The Polyimide diaphragms supersede titanium diaphragms, being able to play low frequencies without shattering and performing more accurately at high frequencies.

*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
