The Speaker Factory grew from Ray Indris’s 1959 hobby into a long-running custom audio business in Gaithersburg, Maryland. Today, the company builds made-to-order high-resolution speakers under its Quanta Technologies brand while helping local audiophiles repair or improve systems they already own. Its defining character is a hands-on, engineering-minded approach that treats speaker cabinets as worth preserving rather than casually replacing.
Bache AudioBache Audio is a small Brooklyn company that handcrafts high-fidelity speakers and single-ended amplifiers, an effort that began when founder Greg Belman built audio equipment for his own listening. Its designs favor wide-band drivers, quasi-coaxial alignment, and straightforward circuitry, while custom finishes and made-to-order builds let listeners tailor speakers to their rooms. A Brooklyn listening room offers customers the chance to hear the speakers before buying.BROOKLYN, NY
