DS18 SRW8.4
The SRW8.4 is a compact 8‑inch shallow‑mount car subwoofer designed to deliver deep, punchy bass in vehicles with limited installation space. Featuring a single 4 Ω voice coil (SVC) with a 1.5″ high‑temperature aluminum voice coil former, it offers reliable performance with 150 W RMS and 300 W peak power handling. The rugged design includes a paper cone, rubber surround, a 32 oz ferrite magnet, and a durable steel basket, ensuring consistent low‑frequency output. With a sensitivity rating of about 86 dB and a frequency response from approximately 25 Hz to 250 Hz, the SRW8.4 provides strong bass for both ported and sealed enclosures. Its shallow mounting depth (about 2.95″ / 75 mm) and compact size make it ideal for tight spaces such as under‑seat boxes or slim custom builds while still delivering notable low‑end impact.
