The Snell Type A is a three-way, acoustic-suspension floorstanding loudspeaker system introduced by Snell Acoustics in the late 1970s and hand-built under Peter Snell's direction. It uses a two-box stacked enclosure: the lower cabinet houses a long-throw 10" mass-loaded paper cone woofer in a sealed enclosure, while the upper cabinet contains the 4" midrange driver, 1" soft-dome tweeter, and the majority of the complex crossover network. The two sections are connected via a jumper cable, and the architecture allows separate amplification of bass and upper ranges (bi-amping) when configured appropriately. In the original Type A and early series, the upper enclosure employs an unconventional curved/biconvex front baffle with carefully shaped padding to reduce edge diffraction and improve stereo imaging and soundstage depth. The speakers are known for a large, stable soundstage with height and depth, highly natural tonal balance, and excellent low-frequency extension for an acoustic-suspension design. Each pair was individually measured and hand-matched, with crossover networks tuned to closely track a laboratory reference, a process overseen by Peter Snell to keep channel differences within a very tight tolerance. Key system specifications for the Type A line include: three-way dynamic acoustic-suspension configuration; nominal impedance of 4 ohms; sensitivity of 86 dB/W/m; and, for the later Type A/III variant, a published frequency response of 24 Hz-26 kHz +/-3 dB with an added rear-firing supertweeter, revised crossover points at approximately 275 Hz and 2.7 kHz, and greater cabinet height and weight compared to earlier versions. Physical dimensions for the original Type A are approximately 46.5" H x 24" W x 13" D, with a weight around 97 lb per cabinet, while the taller Type A/III measures about 50.5" H x 23.5" W x 14" D and is significantly heavier. All Type A models are long out of production, but they remain highly regarded in vintage hi-fi circles for their musicality, imaging, and build quality.
