Dennis Murphy and the orchestra.

Philharmonic Audio is a small American loudspeaker company built around one designer, Dennis Murphy. Its website describes him as “an economist by profession and a violinist and violist by avocation” who “has been designing crossovers for private clients and Salk Sound for over twenty years.” The company says it is named for the Washington Metropolitan Philharmonic Orchestra, in which Murphy plays in the viola section, and Stereophile reported the same in April 2025. Its earliest archived pages, from 2011, gave the name as the Washington Philharmonic Orchestra and promised the orchestra $50 for every pair of speakers sold.

The company says Murphy “launched Philharmonic Audio in 2012.” The record suggests a slightly earlier start: an archived copy of its website from October 2011 already lists three speakers for sale, at $1,600 to $3,000 a pair. We give both. In 2013 the site called Murphy “our owner” and quoted shipping costs from Bethesda, Maryland, just outside Washington.

From the start the pitch was engineering over ornament. The 2011 site addressed “an audio enthusiast who values serious engineering more than exotic wires, designer capacitors, or cabinetry fashion statements.” Its three-way towers used a dipole planar midrange in an open-backed cabinet, crossovers by Murphy, and transmission-line bass tuning by Paul Kittinger, a retired electrical engineer whom the company credits with transmission-line cabinets for Salk Sound and others, built on modelling software developed by Martin King. Murphy’s earlier crossover work, the site said, included designs for Salk Sound, Ellis Audio and popular do-it-yourself kits. In 2011 Kittinger and Murphy’s “Cavatina” speaker, the company says, won first place in its class at the Parts Express Midwest Audio Fest, a speaker-design competition.

From towers to the BMR, and a relaunch.

The range changed over the 2010s. By 2015 the website listed the Philharmonic 3, a tower with a RAAL ribbon tweeter, an open-back planar midrange and a Scan-Speak Revelator woofer in a folded transmission line, at $3,300 a pair, alongside a Slims Tower, a Philharmonitor bookshelf speaker and budget “Affordable Accuracy” models from $175 a pair; cabinets for the three-way speakers were “hand-crafted to order in the USA,” it said. By 2018 the lead product was the BMR Philharmonitor, a three-way stand-mounted speaker pairing a RAAL ribbon tweeter with a Balanced Mode Radiator midrange — a flat-diaphragm driver that moves as a piston at low frequencies and bends at higher ones, to keep its sound spreading widely.

In October 2019 the website told visitors: “We are unable to take new orders at this time.” Stereophile reported in 2025 that in 2020 Murphy announced he intended to close the company, and that Ken Lin, whose company Alexis Sonus had supplied cabinets and crossovers for the BMR Monitor and sold it in Taiwan, offered to take over operations, leaving Murphy the crossover design. The company now calls the result “Philharmonic Audio 2.0,” co-founded by Lin in 2020. Lin told Stereophile the line grew “from one product to six speakers and two accessories,” and that the website began taking orders directly in 2024; before that, buyers emailed and Murphy sent an invoice.

The current range, on its website in October 2026, runs from the True Mini and Ceramic Mini monitors through the BMR Monitor, from $950 each, and the Super BMR Monitor to the Cantabile, BMR and HT towers and an HT centre channel. The BMR Monitor’s front plaque reads Alexis Sonus, Stereophile noted; Lin explained the speaker as a joint venture between the two companies, sold in North America as Philharmonic Audio.

Design and documentation.

The seven names here are loudspeaker brands sold in America. The oldest is Altec Lansing, formed on 1 May 1941, English Wikipedia says, when the theatre-sound firm Altec Service Company bought the nearly bankrupt Lansing Manufacturing Company. After many owners, the name now appears on Bluetooth speakers and headphones; its website does not say who owns it.

Infinity Systems was founded in Los Angeles in 1968 by Arnie Nudell, John Ulrick and Cary Christie and has belonged to Harman since 1983, according to English Wikipedia; Harman now belongs to Samsung. Snell Acoustics began in Newburyport, Massachusetts, in 1976, moved to Haverhill and then Peabody, and ceased manufacturing in May 2010, its website said. Dunlavy Audio Labs, the physicist John Dunlavy’s company in Colorado Springs, was listed by Stereophile in 2008 as no longer in existence.

Two are small current makers. Fritz Speakers is the Southern California workshop of John “Fritz” Heiler, who has built speakers since 1973, trade press reports. Philharmonic Audio, which says it now assembles its speakers in Vienna, Virginia, was launched by the crossover designer Dennis Murphy in 2012, by its own account, and relaunched in 2020 with Kenneth Lin, who the company says oversees production.

PureAudioProject is the exception: it sells in the United States but is not an American company. Its 2025 terms name PureAudioProject LTD of Ramat Gan, Israel, with an operating company in Paredes, Portugal; in 2018 Enjoy the Music described a US arm in Iowa City.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

Assembled in Virginia, sourced worldwide.

On where the speakers are made, the company is specific. Its About page says every speaker combines components “made from different countries,” and that its team assembles and checks “the final products in our Vienna VA facility,” in the Virginia suburbs of Washington. Lin told Stereophile in 2025 that the BMR Monitor is “hand-assembled in the US,” with components from China, Serbia, Indonesia and Taiwan. Tracking Angle’s John Marks wrote in March 2025 that the speakers are assembled from mostly foreign-sourced parts and tested at Philharmonic’s facility in Virginia, and guessed from markings on the terminal plate that the cabinets came from China — a guess, as he made clear.

Reviews have been warm. Marks headlined his review of the BMR Monitor “The Loudspeaker Bargain of the Century — At least so far!” Stereophile’s Robert Schryer reviewed it in April 2025, and the company says it is rated Class A in the magazine’s Recommended Components; it also says The Absolute Sound named a $3,800 BMR Monitor system one of the five most inspiring systems at the 2022 Capital AudioFest. We give those two as the company’s claims. We found no published brand guidelines, and the palette here is our own.

For a design guide, Philharmonic Audio shows how a brand can carry its founder’s other life — the orchestra — in its name, and keep that story through a change of management. Compare Salk, the Michigan maker whose speakers used Murphy’s crossovers, and Spatial Audio Lab, another small American speaker maker. For this guide we use a viola-varnish brown and piano ebony with a serif, an unofficial interpretation; no product or logo is reproduced.
