BC75A

BC75A 1.5″ Neodymium Compression Driver

The BC75A is a 1.5-inch throat neodymium compression driver built for professional sound reinforcement systems that need clean, articulate high frequencies at high output. Its 3-inch voice coil, 120 W AES power handling, 110 dB sensitivity and 8-ohm nominal impedance make it a dependable HF engine for line arrays, two-way and three-way full-range cabinets, stage monitors and fixed-install loudspeakers.

Neodymium motor for high output and low weight

A neodymium magnet assembly delivers a strong, tightly focused magnetic field in a fraction of the weight of a comparable ferrite motor. For system builders this keeps cabinet weight down without giving up sensitivity — an important advantage in flown line array modules and touring PA cabinets where every kilogram on the rigging matters. The result is high acoustic output from modest amplifier power, with headroom left for transients.

3-inch voice coil for reliable power handling

This driver uses a large 3-inch voice coil, giving it a bigger thermal mass and a wider contact area for heat transfer than smaller-format units. Rated at 120 W AES (240 W program), it handles long shows, rental use and continuous background-music duty without thermal compression creeping into the top end. Voice coil alignment and suspension geometry are held to tight tolerances so it stays linear at high drive levels.

Standard 1.5-inch throat fitment

With a 1.5-inch throat exit, it mounts to the vast majority of professional constant-directivity and waveguide horns, making it a straightforward drop-in for new designs or a replacement HF driver in existing enclosures. The 8-ohm nominal impedance sits comfortably on standard passive crossover networks and on bi-amped or tri-amped systems driven by a DSP-managed amplifier. If you are new to how these transducers work, this overview of compression drivers is a useful primer.

Why choose the BC75A

High-frequency transducers do most of the work of making a PA system sound expensive. Detail in vocals, the bite of a snare, the air around cymbals and the intelligibility of speech all live in the range this unit reproduces. The combination of a neodymium motor, a 3-inch voice coil and a precisely machined 1.5-inch exit gives smooth response, low distortion at realistic operating levels and consistent unit-to-unit performance — the sort of repeatability cabinet builders rely on when producing systems in volume.

It sits within a full range of Exxo Professional HF drivers, alongside low-frequency transducers, amplifiers, processors and enclosures from our wider pro-audio component range, so complete systems can be specified from a single source.

Frequently asked questions

What size horn does the BC75A fit?

It has a 1.5-inch throat and fits standard 1.5-inch professional horns and waveguides.

How much power does it handle?

It is rated at 120 W AES, equivalent to 240 W program power, at an 8-ohm nominal impedance.

Is it suitable for line array systems?

Yes. The neodymium motor keeps weight low while delivering 110 dB sensitivity, which is exactly what flown line array and column systems require.

Can it be used as a replacement driver?

Yes. The 1.5-inch throat, 8-ohm impedance and 110 dB sensitivity make it a practical replacement for many 1.5-inch HF units, though crossover settings should always be checked against the original specification.
