The components of the Hot spot speakers provide a fully modular system designed for high quality reinforcement of voice and music. These speakers work with the systems controller for active equalization of the system. The speaker is preferred for applications requiring a rugged, portable enclosure, but can be used in permanent indoor sound system installations. The systems controller assures smooth, accurate spectral response across the entire operating range of the Hot spot speakers.

Sharp subsonic and ultrasonic band-limiting filters of the Hot spot speakers reduce power waste, stage noise, high-frequency instability, and interference. The systems controller also provides two independent signal channels. Each of these speakers uses full-range drivers mounted in symmetric vertical pairs on a faceted Articulated Array baffle assembly. The drivers feature low-impedance, edge-wound aluminum voice coils, 12-ounce Ferrite V ceramic magnets, and molded polyester frames. Their advanced cone and motor system give them high linear excursion capability and power output. Tuned reactive air columns reduce distortion by controlling the cone excursion required to reproduce deep bass frequencies.

A built-in directivity control circuit of the Hot spot speakers maintains the vertical dispersion pattern through the high-frequency range. It also protects the drivers from high-frequency overload. The systems controller is a single-rack sized device. It is capable of providing crossover functions, active electronic equalization, and dual channel signal processing for both the hot spot speakers and the 502B or 502BP enclosure. It features -10/+4dB-V input sensitivity switches, all-balanced inputs and outputs, -18/+3dB bass level control, and a bass mono sum switch. It also provides automatic output muting on turn-off, and a secure rear-panel operating mode switch.

The Hot spot speakers are Watts continuous pink noise, band limited to from some limits. The speaker shall is provided with a ducted vent system, tuned at some Hz. The input connector of the particular speaker consists of parallel-wired with some inch phone jacks and two parallel-wired male XLR connectors. The speaker enclosure of the Hot spot speakers shall be composed of mica-reinforced polyethylene copolymer structural foam.

Outer dimensions of these speakers have some particular dimensions; its weight is also varied from speakers to speaker. The speaker shall be the Hot spot speakers system. The speaker system is supplied with a separate systems controller, to be connected before the inputs of the system power amplifiers. The fixed, channel systems controller shall provide active electronic equalization and crossover functions. It can include an operating mode switch, input sensitivity switch, low-frequency output level control, and mono sum switch. The systems controller uses screw type terminal strips for balanced input and output wiring connections. It can fit in the single space of a standard equipment rack for mounting.

The Hot Spot Speakers have a multiple drivers which are very essentials, full-range system with matched active equalization. The transducer complement shall consist of full-range drivers of a particular diameter, mounted symmetrically in vertical pairs on a faceted, removable baffle assembly. Each driver shall have a rated impedance of a particular ohm, resulting in a composite nominal impedance of the particular ohm.
