Designed by an ex-AR engineer, the musically satisfying and modestly priced two-way SL280 was found to rival many more expensive speakers at the time. Good bass extension is coupled with excellent midband transparency. This particular pair is in excellent condition. The crossovers are in spec, and the cabinets have been lightly refinished.

- Liner Notes
The Signet SL280 is, on the surface, a straightforward design. Both the 1" dome tweeter and the 8" polypropylene-coned woofer appear to be sourced from SEAS. The cabinet is rigidly braced — one internal brace located above the woofer, another below. The bracing is said to be asymmetrical to spread out the frequencies at which the cabinet panels vibrate, minimizing resonances. The philosophy at work here is the minimization of energy storage and its rapid dissipation. A knuckle-rap test revealed a well-damped sound, but not one as dead as in those cabinets which emphasize maximum density—a technique which, according to Signet's literature, increases energy storage and dissipates it slowly, causing time-based smearing of the sound. Internal reflections are controlled by a section of U-shaped acoustical foam behind the woofer.
