For sale: A pair of vintage Infinity Reference Studio Monitor 3-way speakers in great cosmetic and functional condition. The RSM’s were manufactured by Infinity from 1979 to 1984 as part of their Reference Standard series when Infinity had the reputation of being one of the most innovative speaker companies around, before they were acquired by Harman-Kardon and that reputation was diminished.
The driver compliment is as follows:
1 - 12” clear Polypropylene Woofer
1 - 5” clear Polypropylene Midrange with rubber surrounds
1 - EMIT Tweeter
Specifications:
Nominal Impedance: 4-8 ohms
Power Rating: 30-250 watts RMS
Crossover Frequencies: 500Hz and 5,000Hz
Frequency Response: 42Hz-32kHz +/-3db
The dimensions are 26.5”H x 15”wide x 10” deep
In 2014 when I purchased these RSM’s, I re-foamed the woofers and re-capped the crossovers using high quality Solen brand audio grade capacitors exclusively. The speakers were in service until recently when I decided to sell them as part of a speaker collection downsizing effort, but are still available for demo.
The price for the pair is $850 cash with local pickup only.
