1000 watt RMS.
76.2 mm / 3" voice coil.
A 15"/38 cm subwoofer built around a 76.2 mm / 3" dual voice coil: 2+2 ohm, 1000 W RMS continuous, 2000 W peak, 89 dB sensitivity. Cone in compressed paper, fibreglass and black paint, large "R" suspension, 180 °C aluminium wire winding. Sold per unit.
Power, measured not promised
RMS = CONTINUOUS POWER. THE PEAK FIGURE IS A SHORT-TERM VALUE: SIZE THE AMPLIFIER ON THE 1000 W RMS
Why this subwoofer
Not a burst figure: 1000 W RMS is the power the voice coil handles continuously, with 2000 W of peak on top.
The bigger the coil, the more heat it dissipates and the longer it survives a real session. Wound with 180 °C aluminium wire.
Two 2 ohm coils: in parallel 1 ohm, in series 4 ohm. You choose the impedance that matches your amplifier instead of the other way round.
Cone in compressed paper, fibreglass and black paint, with large "R" suspension and 5.0 mm of Xmax: it takes the excursion without losing shape.

Complete the system
Before you install it
- Decide the impedance before you wire it. The two 2 ohm coils in parallel give 1 ohm; in series they give 4 ohm. Check that your amplifier is stable at the impedance you choose.
- Match the amplifier to 1000 W RMS. Sizing on the 2000 W figure means overdriving the coil: use the RMS value.
- Build the enclosure rigid. A 15" cone moving this much air loads the box: thick panels, braced and sealed, or the box will lose output and rattle. The manufacturer sheet gives 80 L vented, tuned to 35 Hz.
- Size the power cable for the amplifier, with an inline fuse close to the battery and a ground point on bare metal.
