A 392 oz ferrite motor driving 12 inches at 1,500W RMS.
The OGX121500AD4 packs 1,500W RMS (3,000W Max) into a 12-inch Silver driver built for hard-pushed systems. Its 392.1 oz ferrite motor and a die-cast aluminum basket that eliminates flex under pressure anchor a 3.0-inch CCAR voice coil wound in 4 layers on a black aluminum bobbin. Every unit is SPL-tested and competition-certified before it ships. Dual 4-ohm coils give you two final loads to work with, 8 ohms in series or 2 ohms in parallel, so you can match your monoblock amplifier's stable load.

Questions
Reach the OG Audio team for product questions, order support, warranty claims, and tuning help.
Choose a monoblock that delivers about 1,500 W RMS at the final load you wire, 2 ohm in parallel or 8 ohm in series. Size to the RMS rating, not the Max.
Parallel gives a 2 ohm final load and series gives 8 ohm. Match the load to your monoblock's rated stable impedance, and confirm it before wiring to 2 ohm.
Rated response is 45–300 Hz at 84.8 dB sensitivity. Free-air resonance (Fs) is 45 Hz and maximum linear excursion is 0.63 inch.
Overall dimensions are 12.28 × 10.62 inches and it weighs 25.4 kg (56.0 lb). Check both against your baffle and box before you cut.
