800 watt RMS.
65.5 mm voice coil.
A 12" / 30 cm subwoofer built around a 65.5 mm (2.5") dual voice coil: 2+2 ohm, 800 W RMS continuous, 1600 W peak, 88.5 dB sensitivity. Compressed paper and fibreglass cone, large “R” suspension, 180 °C aluminium winding. Sold per unit.
Power, measured not promised
RMS = CONTINUOUS POWER. THE PEAK FIGURE IS A SHORT-TERM VALUE: SIZE THE AMPLIFIER ON THE 800 W RMS
Why this subwoofer
Not a burst figure: 800 W RMS is the power the voice coil handles continuously, with 1600 W of peak headroom 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 coils: in parallel 1 ohm, in series 4 ohm. You choose the impedance that matches your amplifier instead of the other way round.
Compressed paper with fibreglass and black paint, large “R” suspension: 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 800 W RMS. Sizing on the 1600 W peak figure means overdriving the coil: use the RMS value.
- Build the enclosure rigid. A 12" / 30 cm cone moving this much air loads the box: thick panels, braced and sealed. The manufacturer does not publish a recommended volume for this model — ask our support before you cut the panels.
- Size the power cable for the amplifier with an inline fuse close to the battery and a ground point on bare metal.
