A Heritage of Innovation and Patents

Phase Technology’s history is synonymous with the history of modern audio. Founded in 1955 as United Speaker Systems, the company was led by industry legend Bill Hecht, the inventor of the soft dome tweeter (US Patent #3328537). This single innovation became the global standard for high-frequency reproduction over the last half-century.

Their commitment to engineering excellence continues under the leadership of Ken Hecht, who has integrated aerospace-grade materials like Kevlar and titanium into the product line. Key patented technologies available to Security Supply customers include:

• Self-Damping Woofer Voice Coils: For superior thermal management.
  
• Silicone-Injected Drivers: To eliminate unwanted resonance.
• Positive Clamping Systems: The ubiquitous "dog ear" mounting tabs—industry standards for secure, vibration-free custom installations.

Precision Engineering & Quality Control

Unlike many "brand name" speakers that are merely assembled, Phase Technology is one of the few fully vertically integrated manufacturers in the United States. From their state-of-the-art facility in Lenexa, Kansas, they produce their own:

• Drivers and Crossovers
• Voice Coils
• Custom-tooled Cabinets (utilizing 8.5-ton CNC routers)

Each speaker undergoes rigorous testing in anechoic chambers and evaluation under Dolby Digital and DTS standards. This meticulous "tweaking" by ear ensures that every unit delivered by Security Supply meets the highest standards of tonal balance, clarity, and dynamic range.
