Built to extract the full capabilities of our wide-bandwidth ring radiator drivers, B&C's new ME464 is the largest commercially available horn for professional audio. The 22” (575mm) wide mouth loads an attached driver to 300Hz, and the 1.4” throat stabilizes a 80° x 60° polar pattern to the upper limit of human hearing. Made of durable and non-resonant polyurethane, the ME464 can stand up to road use as well as shine in high output arrays in fixed installation. Reduced inter-box interaction and off axis energy from the tight pattern brings immediate benefits to sound quality and clarity, and the ME464 is the only horn which can support the full frequency response of our DCX464 coaxial driver. The ME464 can be easily applied to the DCX464 using the FB468 crossover, which is available in 8 or 16 Ohm configurations.
