Carver

Bob Carver's magnificent obsession with impossible power

History

Carver Corporation was founded in Edmonds, Washington in 1972 by Bob Carver, a brilliant engineer who would become known for controversial but innovative audio designs. Carver's philosophy was to challenge conventional wisdom through creative engineering. Bob Carver first gained fame with the Carver Silver Seven (1980s)—monoblock amplifiers that used a unique "magnetic field" output stage. Carver claimed these 375-watt amplifiers could sound like high-end tube amps costing ten times as much, leading to famous debates with high-end manufacturers. The M-400 and subsequent M-1.0t amplifiers featured "cube" power supplies that were remarkably compact for their power output. Carver's "Tracking Downconverter" technology allowed massive power from small chassis. Carver also developed Sonic Holography—a signal processing system that attempted to correct room-induced crosstalk and create more holographic imaging. The Sonic Hologram Generator (C-4000 preamp) implemented this technology. In 1990, Carver Corporation was sold to Curtis Mathes, and Bob Carver left to form Sunfire. The Carver brand continued but lost its innovative edge.

Legendary Products

Carver Silver Seven (1980s)

Monoblock amplifiers that challenged high-end conventions. The Silver Seven's "magnetic field" design delivered 375 watts with claims of tube-like sound. Famous challenge to high-end manufacturers.

Carver M-1.0t (1980s)

A stereo power amplifier using "Tracking Downconverter" technology. The M-1.0t delivered 200 watts per channel from a remarkably compact chassis.

Carver C-4000 (1980s)

A preamplifier featuring Sonic Holography processing. The C-4000 attempted to create more holographic imaging through electronic crosstalk cancellation.

Carver PM-1.5 (1980s)

A massive power amplifier delivering 375 watts per channel. The PM-1.5 represented Carver's ultimate statement in power amplification.
