At 112 dB this driver sits above the midrange without asking for huge power. 51.6 mm / 2" voice coil, CCAW wireThe coil measures 51.6 mm / 2" and is wound in CCAW (aluminium). That is the part that turns 400 W RMS into pressure and then has to survive it. 25 mm (1") throat, your hornThe throat is a standard 25 mm (1"). You choose the horn: flare, dispersion and look are your decision, not ours. 600 Hz – 20 kHz, 34 oz magnetRated from 600 Hz to 20 kHz on a 34 oz magnet assembly. A wide usable band for a front stage or an SPL wall. “Continuous RMS only. No peak, no burst, no marketing watts.” 03Look at it closely 01 · the throatThe 25 mm (1") throat, where your horn screws on.

Never full range. A compression driver wired straight to the amplifier does not survive. Use a crossover, or at the very least a capacitor in series. Do not cross below 600 Hz. 600 Hz is the lowest frequency this driver is rated for. Going under it, at any power, is the fastest way to tear the diaphragm. Do not go below 4 ohm per channel. 4 ohm is the minimum load. Two drivers in parallel on one channel give 2 ohm: most amplifiers will heat up or go into protection. Add a horn before you play it. This driver ships without one. Mount it on a 25 mm (1") horn, aim it at the listener, then bring the gain up slowly. Clipping kills compression drivers far more often than power does. 08Questions installers ask How much power does the SP DRIVER 50 handle?400 W RMS continuous and 800 W peak. The price on this page is for one piece. Is the horn included?No. This driver is sold without the horn. You mount it on a 25 mm (1") horn of your choice. Do I need a crossover?Yes, always — a crossover or at minimum a capacitor in series. And never cross below 600 Hz. How big is the throat?25 mm (1"). One or two?One.
