The Omnidirectional MLTL By Joey Roth ($450) takes a small 2″ speaker and wraps it in a beautiful package that delivers incredibly natural sound. So why a transmission line speaker? Most mass produced speakers are housed in either sealed boxes or boxes with ports/vents. Both of these setups colors sound as a result sound waves bouncing off the cabinet walls and hitting the bass driver. These cabinets also suffer from high pressure that builds up behind the bass cone that results in a ‘canned sound’.
Transmission line speakers sound better because the line resolves the pressure issue and the issue of waves bouncing back through the rear of the driver, by forcing the air through an internal labyrinth. The TL also loads the bass driver and lowers its resonant frequency. This extends the low end while also reducing the work required by the driver. Joey Roth’s speaker is a mass-loaded transmission line that uses quarter-wave harmonics to extend that bass response.
Joey’s MLTL is 15.5 inches high has a 3 inch length and a 4 inch width. It utilizes a 2 inch Fountek FR58EX full-range speaker along with a wood ball that diffuses the sound in all directions. Additional features include a Bluetooth antenna and a TPA3118 amplifier setup in bridge mono. This speaker comes in either Raw aluminum or graphite and will look great in any environment.
