Fulcrum Acoustic CX/DX Family Of Loudspeakers Join TQ Install Series At 2009 InfoComm

AT 2009 InfoComm in Orlando, Fulcrum Acoustic debuted the CX/DX family of loudspeakers, the first of the TQ Install Series.

Eight different products, all based on coaxial designs, provide 90- x 45-degree or 60- x 45-degree horn patterns and 12-inch or 15-inch woofers.  A newly designed coaxial transducer/horn assembly, along with TQ processing, alleviates the problems previously associated with coaxial approaches.

For example, the CX1595 is a coaxial loudspeaker that packs the output capability of a non-coaxial 15 inch, horn-loaded-HF loudspeaker into a much more compact enclosure. Its coaxial transducer can be rotated in 45-degree increments, which allows a user to precisely tailor coverage to best suit an application’s requirements.

The enclosure’s 40-degree trapezoidal shape may be mounted close to ceilings or in tight-packed vertical arrays.

The CX1595 requires digital signal processing, and many platforms are supported. Those platforms capable of implementing Fulcrum Acoustic’s TQ processing give the CX loudspeakers exceptional clarity and studio-monitor-like transient response even while it delivers high sound pressure levels.

When used with TQ processing, the CX Series and the companion dual-woofer DX Series loudspeakers provide exceptional clarity and consistent voicing even while delivering high sound pressure levels.

The proprietary horns employed in the CX series represent a modern digital-signal-processing-aware update to the traditional horn-loaded coaxial loudspeaker concept. The well-known benefits of the coaxial approach have been realized without the familiar shortcomings of historical designs.

Fulcrum Acoustic’s Temporal Equalization (TQ) digital signal processing techniques eliminate midrange colorations and high frequency harshness while producing a smooth, seamless coverage pattern through the crossover range.

In fact, the coaxial transducers were designed from the ground up to take advantage of the unique capabilities of TQ.

The coaxial transducer in the CX1595 includes a 3-inch diaphragm compression driver. The large diaphragm area permits the compression driver to operate at frequencies too low for smaller compression drivers to handle. This allows the high frequency horn to smooth the polar response of the low frequency section in the frequency range where the horn would otherwise cause shadowing.

It also allows the compression driver to produce extreme sound pressure levels with an effortless sonic character.

The coaxial woofer’s large radiating surface works in conjunction with the HF horn to improve directional control at the bottom of the horn’s operating range, increasing directional control beyond what can be accomplished by the horn alone.

The coaxial transducer’s compact, neodymium magnet not only minimizes weight, but also allows very tight spacing between the compression driver and woofer voice coils.

The delay between the driver outputs is thereby minimized, which allows the coaxial device to work well with a passive crossover.
