PRORECK 12-Inch Dual Subwoofer Pair

The PRORECK 712D4x2 supplies two 12-inch subwoofers in a single package, each rated at 800W RMS and 4 ohms impedance. Dual voice coils on every driver give wiring flexibility for mono or stereo amplifier configurations. The pair handles 2400W maximum power combined for high-output car audio systems.

Ideal for Bass Enthusiasts Building High-SPL Systems

This twin-driver kit suits installers who want maximum cone area and the wiring options that dual voice coils provide. It is not for buyers who need a single subwoofer to save enclosure space or amplifier channels. It is also not for vehicles where 42.5 pounds of combined weight exceeds mounting capacity.

800W RMS Per Driver Decides Amplifier Matching

Each subwoofer delivers 800W RMS continuous power handling, so the amplifier must supply clean power at that level into a 4-ohm load per coil. The 45 Hz frequency response sets the low-end extension limit for sealed or ported enclosure tuning.

Questions about this item

How do I wire the dual 4-ohm voice coils on the PRORECK 712D4x2 to my amplifier?

Each subwoofer has two 4-ohm coils; wire them in series for an 8-ohm load or in parallel for a 2-ohm load per sub, then combine the pair to match your amplifier’s stable impedance range.

What part of the PRORECK 712D4x2 will need attention after extended high-power use?

The dual voice coils and suspension are the primary wear items; prolonged 800W RMS operation can heat the former and fatigue the surround, eventually requiring reconing or driver replacement.

At what point does the PRORECK 712D4x2 hit its thermal limit during sustained playback?

Continuous operation at the rated 800W RMS will cause voice-coil temperature to rise until the thermal limit is reached, triggering power compression and protecting the windings from damage.
