Vintage Allison Model Six // Speakers

The Allison Six is a brilliant design, with a shocking level of low end from such a little cabinet. In stark contrast to most speakers who call themselves "bookshelf" models, the Allison Six looks you dead in the eye when they say it. Specifically intended for use with its back to the wall, on a shelf, table, or bookcase – even mounted on the wall. Their versatility is second only to their aesthetics – these little lookers would be right at home in nearly any design-forward listening room.

Liner Notes

The Allison:Six is the smallest, and lowest priced addition to the Allison Acoustics speaker line. The half-cubic-foot Allison:Six is just large enough to enclose its 8-inch woofer, which faces upward and radiates frequencies up to 2,000 Hz. The dome tweeter, which faces forward, is identical to those used on all other Allison speakers, with a proprietary dome design that gives it exceptional dispersion. Like the other Allison models, the Six is meant to be installed against a wall, in which position the woofer .output is most uniform because there are no cancellations of its output from wall reflections within its frequency range.
