DS18 DFPU110iX
Under-Seat Sealed 10” Shallow Subwoofer Enclosure
The DFPU110iX is DS18’s low-profile solution for adding real bass in tight spaces. This compact sealed enclosure is pre-loaded with a single 10” shallow-mount subwoofer: for deep, clean low-end even when space is at a premium.
Built for Any Rig
Perfect for under-seat installs, this enclosure was made for the real-world setups in Jeep Gladiators and pickup trucks. With a durable black carpet finish, it blends seamlessly into your interior without screaming for attention.
Slim Box, Big Output
Built from tough ¾” MDF, the DFPU110iX handles 600W RMS / 1200W MAX and features a 2-ohm final impedance for easy amp pairing. Tuned for a 30Hz drop point, it hits the lows without mud or rumble. And with a 0.32 ft³ sealed volume, the box keeps response tight and musical.
Speaker Specs That Matter
Inside the box, the loaded 10” sub uses a 2.5” black aluminum voice coil, glass fiber dust cap, and non-pressed paper cone for that signature DS18 LOUD you’ve been looking for. Finished with a rubber surround and ferrite magnet, it’s all performance—no compromise.
