0.72 inch of Xmax and 1,500W RMS behind a 15-inch cone.
The OGX151500AD4 is the 15-inch Silver driver for builds that need serious cone area behind 1,500W RMS (3,000W Max). A 392.1 oz ferrite motor, a 3.0-inch CCAR voice coil standing 2.36 inches tall, and a die-cast aluminum basket that eliminates flex under pressure make up the build, and every unit is SPL-tested and competition-certified before it ships. Its 0.72-inch Xmax gives the cone room to move serious air. Dual 4-ohm coils wire in series for an 8-ohm final load or in parallel for 2 ohms, 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.
3,000 W Max is the burst ceiling above the 1,500 W RMS continuous rating. Match your amplifier to the RMS figure, the level the driver is built to hold across a sustained run.
Rated response is 46–300 Hz at 86.9 dB sensitivity. Free-air resonance (Fs) is 46 Hz and maximum linear excursion is 0.72 inch.
