The PRO-X6.4BM is a 6.5" mid-range loudspeaker built for high-output car audio, powersports and pro audio systems. It handles 250 watts RMS and 500 watts max power at 4 ohms. A 95dB sensitivity rating converts amplifier power into clear, audible output efficiently, so you get more volume from the power you already have. The frequency response spans 100Hz to 10kHz. A bullet phase plug at the center of the cone widens frequency dispersion and adds structural strength to the cone assembly. Sold individually, so order the quantity your build requires. | Ds18 Audio | | PRO-X 6.5" Mid-Range Loudspeaker with Bullet, 250W RMS 4-Ohm | Best Buy
