Cerwin-Vega Stroker 18S
The Stroker 18S is documentation-thin for a driver this serious. The record consists of the official Cerwin-Vega manual and little else — no production years, no original price, and no period reviews. What the manual does tell us is unambiguous: this is an 18-inch subwoofer built to take a beating.
The specs are all muscle. It's rated for 1,000 watts RMS and 2,000 watts peak, with a 4-ohm impedance, 97dB sensitivity, and a frequency response spanning 25Hz to 1kHz. The motor is a 240-ounce magnet, and the voice coil is a 4-inch CCAW unit. Construction details from the manual point to serious excursion capability: a triple stacked spider suspension and a cast aluminum frame. The cone is non-pressed Kevlar with a foam surround.
That's about the extent of what's verifiable. No dimensions or weight are recorded, and there's no documented history of how the Stroker 18S fit into Cerwin-Vega's broader Stroker line. A 1987 profile of the company in Mix (April 1987, p.73) noted that Cerwin-Vega's high visibility was largely due to owner Gene Czerwinski, an electrical and acoustical engineer who personally promoted the company's early products. If you own one, you're holding a high-power 18-inch subwoofer from a company known for loud — and the manual confirms it was engineered for exactly that.
