Great looking and capable set of vintage "Pi" speakers from AR. Sorted and ready to be the star of your living room.

Super even-colored real wood veneer and perfect grills, and featuring panel mounted attenuator switches that allow you customize the "woofer environmental control (impedance) and for midrange and highrange level control". See specs below for a bit more detail.

We re-foamed the woofers and cleaned up the cabinets ensuring another 40 years of happy enjoyment in their new home.

In the listening room we were amazed by the amount of bass this moderately sized speaker can produce.

More from Acoustic Research, Circa 1977:
The Acoustic Research 10π is a new speaker system from Acoustic Research that addresses itself to these considerations. Under actual listening conditions, the AR-10π delivers as flat an energy response as the state of the art permits. And it is able to maintain this response characteristic under a great variety of conditions of use. The result is a further significant improvement in the degree of realism with which music can be heard in the home.

The AR-10π - is designed to reproduce music in the home as accurately as the state of the art permits. Its ability in this respect represents a number of significant evolutionary improvements over previous designs. Further the AR-10π - is intended to offer an unprecedented degree of flexibility without any sacrifice in accuracy. The combination of these characteristic, we believe, represents a significant step forward in loudspeaker design.

The AR 10π is a no-compromise 3 way speaker system with excellent dispersion and even energy output all across the audible spectrum. A pair of 3 position switches allows the owner to adjust the mid and high-range drivers to the "liveliness" of the room while the 3-position woofer environmental control allows the owner to adjust the low-end response to speaker placement. This allows the owner to place the speakers on the center of the wall, on the floor against the wall or away from the wall.

SPECIFICATIONS
