Infinity Reference Standard RS II-B Vintage Ribbon Speakers with LF EQ, Near Perfect
These well regarded vintage Infinity speakers have one of the most unique driver configurations out there. There are 3 ribbon midrange drivers radiating front and back, two forward tweeters and one rear facing tweeter, and 2 poly woofers.
While these are not the most accurate speakers ever made, many connoisseurs love them for their musicality and ability to engage the listener. It is a full range speaker and is capable of deep bass. The controls on the back let you dial in all 3 frequency ranges to match your room listening position and taste.
These beauties include a rare matching bass EQ, which as the manual states, must be used with this model to achieve a flat frequency response and to dial in the bass precisely. I have seen these speakers sold many times without the proper bass EQ, as many folks seem to misplace it during a move or as the speakers trade owners.
Condition on these speakers is spectacular without a single noticeable dent or deep scratch. Quite the achievement for a speaker this size and age. Even the grills are perfect! I suspect this is because the original owner had them since new, and never moved them from their original installation location in his NYC apartment where we retrieved them.
They were powered with a McIntosh MC-275 which provided ample volume and power, and is a great match for these fairly easy to drive speakers.
