Акустическая система Acoustic Research AR48s ( Made in USA)
250mm acoustic suspension woofer
100mm acoustic suspension midrange with a mechanically-inert diaphragm of GPS (unit in its own subcavity)
25mm liquid-cooled dome highrange driver.
Efficiency-1 watt produces 87 dB SPL at 1 meter on axis.
Power Handling Ability-May be used with amplifiers capable of delivering up to 100 watts continuous power per channel, being driven into clipping no more than 10% of the time on normal speech and music source material in non-commercial applications.
System Frequency Response- -3 dB (half power) points at 45 Hz and at 32000 Hz.
Impedance-6 ohms nominal
Crossover Network-Woofer and midrange use a series network which is combined with a second-order parallel network on the upper end of the midrange. High range has a second order parallel network for a 12 dB/octave slope. Network uses air core chokes wound with low-loss copper conductor and high-grade bipolar electrolytic capacitors.
Crossover Frequencies-400 Hz and 2500 Hz.
