Operating Instructions

The 650-R2 is designed to be operated as a

system with the Meyer Sound B-2EX Control

Electronics Unit. The B-2EX comprises elec-

tronic crossover, Meyer Sound exclusive

SpeakerSense™ driver protection circuitry, and

amplitude and phase response alignment cir-

cuitry optimized for the loudspeaker.

The Meyer Sound 650-R2 is a high-power sub-

woofer loudspeaker designed to extend the

power bandwidth of Meyer Sound reinforcement

systems to 30 Hz. The system consists of two

18-inch cone drivers in a heavily braced 14 cu.

ft. vented enclosure. The dimensions of the

cabinet are submultiples of 90", the U.S. internal

truck width standard. The cabinet is fitted with

handles and high-density rubber casters.

650-R2 Reinforcement Subwoofer Operating Instructions Amplifier Requirements The 650-R2 requires a professional quality two-channel power amplifier capable of delivering up to 350 watts per channel into 8 ohms or 750 watts per channel into 4 ohms (FTC rating). Use of amplifiers of lower power will not allow the full power and headroom of the 650-R2 system to be realized.

650-R2 Reinforcement Subwoofer Arraying Operating Instructions The 650-R2 Subwoofer adds very well in arrays. Because of the long wavelengths of low frequencies, small 650-R2 arrays will tend to be essentially omnidirectional. Larger arrays may be constructed, however, which can provide the directional control required to project the low-frequency energy forward efficiently. Some examples of such arrays are shown in the illustrations below.
