The Martin USA TL-1450 is a vintage compact loudspeaker system from the 1980s, designed by Fred Martin and recognized as one of the smallest transmission line (using a proprietary "Transflex" bass loading system) speakers ever built.

Design and Engineering

• Enclosure: Uses a compact bass-reflex / transmission line hybrid system called Transflex.

• Dimensions: Exceptionally tiny for a transmission line design, measuring roughly 23–25 cm high, 13 cm wide, and 17–19 cm deep.

• Drivers: Typically utilizes high-quality Scandinavian components, famously featuring the Seas H149 (CA11RCY) woofer alongside a precision dome tweeter.

• Specifications: Handled around 50W nominal power (70W musical power) at 8 ohms, with a reported frequency response of 50 to 25,000 Hz.

The presented units are in a near mint condition. See comparison with other bookshelve loudspeakers to get an idea of the increadible small size of these great sounding speakers.
