The rear-firing port influences placement. Unlike front-ported speakers, the AT-40 needs some space behind it (at least 6-12 inches) to allow the port to breathe. Placing them flush against a wall will artificially boost bass but may cause muddiness or "chuffing" noise.
The cabinet is constructed from 3/4" MDF with internal bracing. At 52 lbs each, they are solid but not impossible to move. The vinyl veneer finish is functional but not high-end furniture grade—these are workhorse speakers, not art pieces. cerwin vega at-40 specs
The AT (Acoustic Track) series was introduced in the late 1980s and early 1990s as a mid-to-high-end floor-standing line. The AT-40 was the "bookshelf on a stand" or compact floor-standing model—designed for rooms that couldn't accommodate the massive AT-15 or AT-12, but still demanded high output.
Unlike modern "audiophile" speakers that require hundreds of watts to produce moderate volume, the AT-40 was built for high efficiency. You could drive these to ear-bleeding levels with a modest 35-watt receiver. | Specification | Detail | | :--- |
