Stetron

What Stetron does

Stetron International, founded in 1965 and headquartered in Buffalo, New York, with a regional office in Markham, Ontario, is a privately held supplier of acoustic transducers and integrated audio solutions serving OEMs worldwide. Its product portfolio spans four core component families: loudspeaker drivers (10mm to over 100mm), dynamic receivers (including HAC variants for hearing-aid compliance), electret condenser microphones (with waterproof designs rated to 200m), and integrated audio sub-assemblies featuring custom enclosures. Underlying technology is anchored by an in-house anechoic chamber and test lab using HATS, CLIO, and SoundCheck equipment for Thiele Small parameter, impedance, life, and load measurement, complemented by loudspeaker software simulation, component/system simulation, and 3D printing/CNC rapid prototyping for fast sample turnaround.

The company's go-to-market is a sample-and-contact-driven direct sales motion targeting engineering and procurement buyers at OEMs in Fire & Safety (UL1480/ULC-S541/UL217/UL464/EN54-24 compliant speakers), Medical Device (IEC 60601-1-8 compliant speakers for nurse call, AEDs, ventilators, surgical robots), Telecom (TIA 920 wideband speakers for conference phones), Industrial/First-Responder (high-temperature, IP67 microphones and speakers for SCBA and two-way radios), Personal Emergency Response Systems, and Consumer Electronics/Gaming. Pricing is quote-based, negotiated per project against customer-specified Estimated Annual Usage, Planned Start of Production, and Target Price, with a multi-year contract cadence typical of OEM supply arrangements. Distribution is augmented by online sales through DigiKey.com, and Stetron supplements hardware sales with Audio Engineering & Design Services covering custom enclosure design, full audio design, simulation, and a web-based Integrated Audio Solutions Design and Comparison Tool. The company is ISO 9001:2015 certified and markets through its own website (product catalogue, Audio Insights blog, Resource Library, mailing list), SEO, paid online ads, trade press, social media, and word-of-mouth referrals.

Revenue model

1. Hardware/component sales (speakers, microphones, dynamic receivers, audio sub-assemblies): Sale of standard and custom-designed acoustic components (loudspeaker drivers, electret condenser microphones, dynamic receivers, integrated audio solutions). Customers typically request samples and indicate Estimated Annual Usage, Planned Start of Production and Target Price, indicating project-based OEM supply arrangements rather than retail shelf sales. Also distributed online via DigiKey.
2. Audio Engineering & Design Services: Custom acoustic component design, component and system simulation, "fast to market" project optimization with CNC samples, and benchmark product investigation. Includes Custom Enclosure Design, Full Audio Design, and Integrated Audio Solutions Design and Comparison Tool engagements.

Core offering

Stetron designs and manufactures loudspeaker drivers (10–150 mm), dynamic receivers, electret condenser microphones, and integrated audio sub-assemblies, with custom acoustic enclosure and audio engineering design services. The portfolio supports OEM applications in fire and safety, medical, telecom, gaming, PERS, and industrial/first-responder markets, with in-house anechoic chamber testing and rapid 3D/CNC prototyping. Products are sold direct to OEMs via sample-driven sales and through DigiKey online distribution.

Product overview

Stetron is a single-company audio solutions provider that manufactures a portfolio of related component products and engineering services rather than a multi-module software platform. The portfolio centers on four core component families — Loudspeaker Drivers (Speakers, 13mm to over 100mm), Dynamic Receivers (telecom/headsets), Electret Condenser Microphones (ECMs), and Integrated Audio Solutions (audio sub-assemblies with enclosure design) — supported by Audio Engineering & Design Services, Custom Enclosure Design, and an Integrated Audio Solutions Design and Comparison Tool on the website. Featured and industry-specific offerings include the D0040008NM89WER low-profile IP67 loudspeaker (medical/portable), the EO401522240W7MGR IP67 ECM microphone, the D0050008NMX16GAR high-temperature mid-range speaker, the D0036004NC22AAR medical midsize speaker (IEC 60601-1-8), and the D5353004NR011WER / D0077008NU26DAR / D0077004FR060FAR wideband conference speakers for video and teleconferencing. The component families, services, and design tools together constitute Stetron's "One Source. Many Solutions." offering for Fire & Safety, Medical, Telecom, Gaming, PERS, and Home Automation applications.
