About: PRV Audio 69MR500-4 BULLET 6x9" 500W RMS Midrange Bullet Loudspeaker - 4 Ohm (Each) 

Featuring an Aluminum Phase Plug (Bullet), this mid is built like a professional mid range loudspeaker, but it has been designed for use in the mobile audio market, as we called it Pro Audio On Wheels!! By combining elements from PRO Audio and Car Audio, we have developed a NEW type of high efficient mid range that is able to give high levels of output for your custom door or rear deck.

The “bullet” phase plug is made from pure aluminum acting as a radiator cooling system for the voice coil and machined to perfection for even sound dissipation. Beyond good looks, this cone is extremely light, providing excellent damping to keep an incredibly natural yet accurate sound.

A triple roll cloth surround, combined with an optimized fiber pressed paper cone, ensure the speaker’s frequency response is smooth and extends to high range making an easy transition to a super tweeter, but according to customers, the high-frequency response from this speaker does NOT need support from a tweeter!

The suspension design of this mid range features a single layer spider – which connects to the coil former with premium stitched lead wires, all being driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling.

Its high-performance characteristics and high-quality components provide exceptional clarity, detail, and dynamics sound. You can expect outstanding sound stage quality and realistic sound reproduction for a great value. This is the new standard of value in high-performance bullet speakers.

Built to perform and able to handle 500 watts of continuous power, this mid range is the perfect option to replace that old 2-way or 3-way coaxial speakers. Engineered and designed to transform a stock system into a concert level, ideal for audiophiles seeking tremendous output without radical modifications.

Note:  

• Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
• Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation.
• Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
