Welcome to Philharmonic Audio Loudspeakers. If you are an audio enthusiast who values serious engineering more than exotic wires, designer capacitors, or cabinetry fashion statements, you have come to the right place. 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, HT2-TL, and the popular ER18-MTM 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 from $2500 to $3500 for our floorstanding models. Each speaker is available in either the old cabinet style (roundover on the edges) or the new cabinet style (chamfered edges with an angled front baffle on the bass cabinet). All cabinets are custom built in the USA and use only premium drivers. Please click below for more information.
Please contact firstname.lastname@example.org to place your order and with any questions. The deposit for any Philharmonic model is the cost of the cabinets, which is $700/pr for the older style,and $900/pr for the newer style with a sloped front baffle and chamfered edges. Standard veneers include straight cherry, mahogany, walnut, maple, and oak. Custom veneers and staining are available for a premium that generally runs from $100 - $300 a pair. The deposit may be paid either by personal check or PayPal. You will be invoiced for the balance plus shipping about a week before the speakers are shipped. Fed Ex Ground charges generally run from $100 to $200, depending on how far you are from Bethesda, MD. The preferred form of final payment is by personal check, but PayPal may be used for a two-percent service charge.
A 14 day in-home trial is available for standard finishes. Buyers are responsible for all shipping costs and any damage. Please contact for more information.
For every pair of speakers sold, Philharmonic Audio donates $50 to the Washington Philharmonic Orchestra. This is something near and dear to Philharmonic Audio and our owner Dennis Murphy. Dennis is the assistant principal violist in the Washington Philharmonic Orchestra and also plays lead violin in two tango orchestras.
