Avatar 18" Car Subwoofer 3500W RMS Dual 1 Ohm 4" Voice Coil Doomsday 18 D1
This Listing Includes
- (1) Avatar Doomsday 18 D1 18" Subwoofer
The Avatar Doomsday 18 D1 is an 18" subwoofer built for high power systems that need serious low end. It’s rated at 3,500 watts RMS (7,000 watts max) and uses a 4" aluminum wire voice coil, a pressed paper cone, a foam surround and a ferrite magnet on an aluminum frame.
This is the dual 1 ohm version. That gives you two wiring options: both coils in parallel for a 0.5 ohm final load, or in series for a 2 ohm final load. Make sure your amplifier is stable at the load you choose before wiring it up.
With 20 mm of Xmax, a 29 Hz Fs and a Vas of 76.40 L (about 2.70 cubic feet), this sub is made to move a lot of air. Plan your build around its size, though. It needs a 16.71" cutout and 12.13" of mounting depth, so check your enclosure’s internal depth behind the baffle before you order.
If you’re building a big single 18 setup or stepping up to a multi sub wall, the Doomsday 18 D1 has the power handling and excursion to back it up.
Features
- Dual 1 ohm voice coils: wire to 0.5 ohm (parallel) or 2 ohm (series)
- Cutout diameter: 16.71" (424.5 mm), measured as the hole size cut in the baffle
- Mounting depth: 12.13" (308 mm), measured from the mounting surface to the back of the motor
- Vas of 76.40 L (about 2.70 cu ft) means it’s a large air space driver, so it isn’t suited for small shallow boxes
- Gross weight: 89.29 lb (40.5 kg); make sure your baffle and enclosure bracing can support it
