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.
