215 ACOST BASS M402

The Acoustic™ Model 402 is the 2×15 bass cabinet from Acoustic Control Corporation, designed in the 1970s to pair with the company's high-output bass heads of the same era. The 402 sits as the more practical, room-scaled sibling to the 4×15 Model 408 — half the driver count, the same period mandate of moving real low-end air into the room rather than precision-controlling it.

Two 15-inch speakers in a single enclosure deliver the kind of sustained low-end fundamental and broad dispersion that made Acoustic rigs a fixture of arena-rock bass setups during the decade.

This particular cabinet has been re-loaded with EVL™ 2×15" drivers — replacement units fitted in place of the originals, voiced toward the same low-end character the 402 was designed around. (The original 1970s drivers are not in this cabinet; the EVL specification is the configuration captured here.)

A reference capture for vintage American bass tone, taken from a working cabinet in a serviceable specification. The IR preserves the 402's enclosure characteristics — the natural cone break-up at higher levels, the rounded deep fundamental that defines 1970s rock bass — and the EVL drivers' faithful reading of the original tonal envelope. The cabinet does not concentrate; it pushes the low end out into the room and pushes it wide.
