DS18 PSW8.4D PS Shallow-Mount Water-Resistant 8" Subwoofer | 400W RMS DVC 4-Ohm — specifications as published by DS18.
DS18 PSW8.4D
8” Dual Voice Coil Shallow-Mount Subwoofer – 400W RMS / 800W MAX
The PSW8.4D is a shallow-mount 8” subwoofer engineered to deliver serious low-end punch in minimal space.
Tight Spots and Deep Drops
With a mounting depth of just 3.5 inches and a total depth of 4”, the PSW8.4D fits clean into under-seat boxes, truck enclosures, and other compact builds but reaches frequencies as low as 20Hz
Dual 4-Ohm Voice Coils for Flexible Wiring
Wired in series or parallel, the dual 4-ohm voice coils give you options for system matching and amp tuning. That means more control over your setup and more reliable performance under pressure.
Hit Hard and Stay Cool
A 2" aluminum voice coil and water-resistant paper + aluminum cone allow for better heat dissipation and long-lasting performance. The ferrite motor and high-roll rubber surround deliver strength and stability for extended play at high volume.
Tuned for Accuracy
With a sensitivity of 81dB and an optimal sealed box volume of 0.35–1.3 ft³, the PSW8.4D balances deep bass with tonal precision.
Bring the boom to any mounting space with DS18’s PSW8.4D!
