Pair of Acoustic Research Hi-Res Series AR1 Floor Speakers WITH SUNFIRE WOOFER

Pair of Acoustic Research Hi-Res Series AR1 Floor Speakers WITH SUNFIRE WOOFER

He AR-1 is a three-way loudspeaker with a 15 woofer driven by a 500W, Sunfire-designed amplifier. Its tower-style enclosure is constructed from ¾ particleboard with picture-frame internal bracing. The tweeter is a 1, plasma-transferred, diamond-coated titanium dome. Surrounding the tweeter is an “energy-control contoured baffle, ” an integral waveguide for the tweeter made of foam of varying density, which controls the unit’s dispersion. This foam ring was used, said Mike Park, to produce a smoother off-axis response pattern by eliminating the edge-cancellation effects of the speaker’s narrow front baffle. Above and below the tweeter are a pair of 5.25 midrange drivers in a D’Appolito configuration. Each of these has a monocoque concave cone-with no dust cap-made from a very stiff magnesium-aluminum alloy. A 1 copper voice-coil is wound on an aluminum former, this said to double the sound-propagation velocity through the cone material and to lower the second and third harmonic distortion compared to a paper midrange cone. Each midrange driver is housed in a specially formulated, compressed-pulp sub-enclosure to provide isolation from the woofer. The 15 is mounted near the floor, on the cabinet’s side-the speaker is supplied as asymmetrical pairs, with left- and right-hand versions. Like the other drivers, the woofer is magnetically shielded. It is driven by an internal, high-efficiency amplifier designed by Sunfire Corporation and licensed to AR that uses a tracking down-converter (TDC). This amplifier features continuously variable power-supply voltages slightly higher than and in sync with the audio signal. Sunfire claims that the design allows its TDC amplifier to approach 85% power-conversion efficiency compared to the 20-30% of conventional designs. This amplifier can thus be a small, lightweight, cool-running, low-cost unit. Its built-in limiter IPC (intelligent parameter control) circuit provides an excursion limiter, a dynamic compressor, a thermal rollback limiter, active low-frequency equalization, infrasonic filtering, and automatic, signal-sensing amplifier turn on/off. The woofer is solidly, ruggedly constructed. It employs a 4-lb magnet, a vented pole-piece to improve voice-coil cooling, a half-roll foam surround, a and a two-layer, long-throw, copper voice-coil, 4 in diameter and wound on an aluminum former to provide high heat dissipation. Its rib-reinforced cone is made from a formulated paper material chemically treated with a clear polymer “Hydra-Plas” resonance-damping compound to reduce distortion and cone breakup. To further increase cone stiffness, the dustcap is inverted. The latest AR-1 includes equalization circuitry to allow the bass-level control to act as a narrow-Q parametric equalizer around 30Hz.

Minimal use but due to age the foam has become fragile to touch and needs to be replaced. Pretty straight forward job with tons of tutorials online. Still sounds surprisingly good the way it is. Original owners manual is included.

AR ACOUSTIC RESEARCH AR2C Hi-Res Series Center Channel Speaker RARE EXCELLENT

PHOTOS OF ACTUAL ITEM! I set it as my center channel but before I could actually use it, I started to relocate so it was packed back and went into storage (climate controlled).
