PRV Audio 8MR450A 8" Alto Series Professional Midrange Speaker
PRV Audio's 8MR450A value priced 8" mid-range loudspeaker features 8 ohms
impedance, under 3-1/4" of mounting depth, and a high sensitivity of 96 dB for
more sound per watt. A triple roll cloth surround supports the cone for
detailed, smooth feedback. For lower distortion a copper sleeve is included on
the pole piece which reduces inductance to increase the high frequency response,
delivering professional sound and peak performance on a budget.
