Boston Acoustic A-150 series II pair just refoamed and ready to rock. Original boxes included. These speakers are excellent. Very nice tweeter with excellent separation and imaging. Sealed cabinet design for low and tight base. These are in darn good condition for their age with some slight blemishes. Real wood veneer. Grills are in good condition with two small holes in cloth. This speaker design is somewhat narrow so they don't stick it into the room, but broad shouldered to get the cabinet volume for excellent base response.
The Boston Acoustics A-150 is a vintage floor-standing speaker that was part of the highly regarded A-series. While there can be slight variations between the original A-150 and the Series II, the general specifications are as follows: General Specifications: Type: 3-way, 3-driver, bass reflex system (though some sources suggest it's an acoustic suspension design). Drivers: Woofer: 10-inch Midrange: 4.5 or 5-inch Tweeter: 1-inch ferrofluid-cooled soft dome Frequency Response: 36 - 25,000 Hz, ±3 dB (some sources list a tighter tolerance like 38-20,000 Hz, ±2.5 dB) Impedance: 8 ohms Sensitivity: 90 dB @ 1 meter Power Handling: 15-75 watts recommended, with a maximum of 150 watts. Crossover Frequencies: 450 Hz and 3,000 Hz. Dimensions: Approximately 32.5 inches (H) x 16 inches (W) x 8 inches (D) with the base. Key Features and Design: Acoustic Suspension/Bass Reflex: There seems to be some debate on this, with different sources citing both designs. However, the A-series is known for its "East Coast sound," which is characterized by a natural, uncolored, and musical presentation. Build Quality: These speakers are known for their solid construction and real wood veneer on some models, which has made them highly sought after by vintage audio enthusiasts. Placement: A unique design aspect of the A-series was that they were engineered to be placed close to a wall, allowing them to blend into a room and use the wall for bass reinforcement.
