Review on 🔊 SLEEK SELENIUM HC2325 Short Throw Horn: Powerful Performance and Precise Sound Projection by Pete Norris

GREAT! Difficult to find such a small horn that can operate up to 600Hz. And they are not designed for maximum sound pressure, but spread the sound across all frequencies. In front of them; it's the classic hard, mean sound that brass is famous for. These horns are only useful when the speakers are far from the audience; then the narrow beam covers every 100-200 people within 100-200 feet. They are correctly classified as "short throw" horns. You can be just a few feet away from them, and they sound the same whether you're looking straight at them or at a 45-degree angle to the side. You can walk across the room and hear no change in frequency response. They are ideal for use in cafes and clubs with audiences of up to 200 people where you do not have the space to mount speakers far from the audience. The key element in all of this is known as "constant focus". ; the horn's radiation pattern does not narrow as the frequency increases. This is ensured by a series of internal baffles and a graduated horn profile. One result is that you get high-end rolloff with any regular compression driver; Aligning constant direction horns is old fashioned and not difficult. In my case, I connected this horn to a 109dB SPL driver in two-way mode with a 94dB SPL woofer crossed at 1.2kHz. I was able to fit the required high gain EQ right into the crossover since I had an extra SPL in the horn. I used Peavey RX22 compression drivers with them - mechanically it was awkward; The Peavey drivers had very sharp threads and wanted to thread the new (aka crossover) soft plastic of the HC23-25 bells. I ended up sanding down the RX22 threads and chasing the threads a lot to get them to work. Also, since the speakers weigh about 8 pounds, I built a mechanical support structure into my speaker cabinets, concerned that the plastic horns would not be able to support the weight, or rather the leverage created would pull the screws out. from a chipboard cabinet (my project was a retrofit so I'm stuck with screws and chipboard). My results are not critical, they are of surprisingly high quality. My goal was to design PA speakers that would accurately reproduce vocals, and this horn cone enabled me to achieve that goal. If I had to start from scratch I would pair these diffusers with the Selenium D220ti driver.
