The AR-7 is a speaker system developed by Acoustic Research it offers the same low distortion, extended and smooth frequency response, and wide dispersion associated with all AR loudspeakers. However, it accomplishes this in a cabinet more compact and at a price lower than other AR speakers.
To accomplish this difficult design target, AR engineers developed a new woofer whose magnetic circuit, voice coil, and precisely controlled moving system mass yield optimal utilization of the acoustic suspension principle for a cabinet of this size. The resulting frequency response extends as low as that of systems of greater size and cost.
The high frequency unit is almost identical to the tweeter used in the highly acclaimed AR-6. the only difference is in the crossover frequency. A selector switch permits the user to choose between two tweeter output levels.
As with other AR loudspeakers, both drivers use high temperature voice coils for additional power handling capability.
The woofer of the Ar-7 uses such advanced design and manufacturing techniques that its low frequency response extends substantially below that of competitive speakers of far greater size.
Due to its compact size, the AR-7 is ideally suited for 4-channel installation. However, its accurate response and modest cost make it a worthy choice for anyone interested in a high quality reasonably priced stereo system.
