Re: Boston Acoustics A-40 book shelf speakers

This is an interesting speaker. In mid-1970's a new concept in speaker design arose. The satellite, it was a small box with good sound that fit anywhere. Most (fullrange) hifi speakers then were big cabinets weighing up to 60+ pounds. The satellites or mini's gave an option. Soon sub woofers appeared making for a true full range mini/sub combo.
The A-40's came out in 1982 and were a hit. I got mine used/refurbished in 2015 for $75 (pair). The 3/4 inch tweeter has almost 90 degree dispersion with bright, open, airy highs and bass is strong to 68Hz (-3dB) and useful below that frequency. They need a mere 5w for good volume. Mine are in my kitchen and placement is near wall ceiling in room corners to enhance bass response. Powered by a Pioneer SX-434, 15wpc receiver the A-40's give an excellent account of themselves and can play quite loud and stay clear and clean. Great while cooking or when I don't want the BIG STEREO on. Who says vintage ain't good??
