About

Welcome to Philharmonic Audio Loudspeakers. Founded in 2011 to provide the audio enthusiast who values serious engineering more than exotic wires, designer capacitors, or cabinetry fashion statements, with one of the best values for their dollar. We strive to provide the most accurate loudspeakers possible at an affordable price.

We currently offer three loudspeakers that differ only in their ability to produce the extremes of the audio spectrum. All of these speakers are three-way designs employing a dipole planar midrange driver that operates in an open-back cabinet to provide added depth and spaciousness to the sound stage without imposing restrictions on room placement.

Our speakers feature transmission line tuning optimized by Paul Kittinger, based on precise mathematical models developed by Martin King. Paul also designed the transmission line cabinets for the popular Salk Song Tower and HT2 loudspeakers. The crossover networks were developed by Dennis Murphy, who has a proven track record in crossover designs for Salk Sound, Ellis Audio, and many popular public domain kits, such as the MB0W1 and CA0W1. Paul and Dennis recently won First Place in the ">$200" category of the country's largest loudspeaker design competition, with the Cavatina.

Our speakers range in price from $2500 to $3500 a pair. For every pair sold, Philharmonic Audio contributes $50 to the Washington Philharmonic Orchestra. (Dennis Murphy is a member of the viola section.)

You will find complete documentation and measurements for all of our speakers on this site. In addition, purchasers will receive frequency response, distortion, and impedance measurements for their individual speakers.
