PRM 165

Passive Reference Monitor

Being ruler-flat over nearly six of its eight and a half octave range (measuring ± ¾ dB from 300 to 15kHz), exceptionally well-matched pairs of 165's are consistently generated, providing extraordinary imaging and ultra-smooth response for extremely non-fatiguing long-term critical nearfield monitoring. A unique hybrid alignment tuned to 40Hz yields dead flat response to below 60 cycles functioning essentially as a sealed second order system down to the cabinet resonance, beyond which it rolls off rapidly fourth order. This technique provides a "no hype" bottom end with increased definition, extension and depth of image, while significantly reducing group delay. Although computer-modeled and tested in the laboratory, the 165 is optimized for the flattest, most accurate presentation possible in real-world studio environments. The shielded 6.5" long-excursion woofer was chosen for its neutral, uncolored extended midrange characteristics, as well as its robust low frequency performance. And in conjunction with its ultra-low distortion recessed 1" dome tweeter, hand-wired crossover, minimal front baffle area and heavily braced rear-vented satin black enclosure with all edges broadly radiused, the PRM 165 provides pinpoint imaging, wide bandwidth and excellent transient response in a 25 pound nearfield package.

Typical 1 π 1/4 space in control room response lowers the 3 dB point to below 53Hz, with bottom octave reinforcement in the 5 to 10 dB range, depending upon proximity to adjacent boundaries.

Although the 165s are very easy to drive, high quality amplification of at least 100 watts per channel into 8 ohms is suggested. PRM 165s are generally packaged with Hot House model Four or Six Hundred stereo amps, or a pair of M500HV monoblocks. The massive current and headroom provided by our two kilowatt dual-mono block model Two Thousand ensures the ultimate nearfield rig, and is recommended for its extra voltage swing when utilizing the 165's as mid-high components in conjunction with our ASB active subwoofers for ultra-wideband (10.5 octave), truly dynamic nearfield applications.
