Designed as a dedicated top-box, M14T is an ultra-compact, lightweight speaker designed for high quality live sound reinforcement. It features a high output mid/bass driver with excellent output and clarity in the midrange as well as a 2" compression driver with a 3" diaphragm. The mid-bass driver has a 3" voice coil with windings on the inside and outside of the voice coil former. As a result the driver has a very balanced mass with excellent clarity and stability when driven hard.
The compression driver features a titanium diaphragm with a polymer fiber surround on a Kapton former, which enables the frequency response to extend to 20kHz with very low distortion. Power compression is kept very low by the use of a flat wire copper voice coil. Weighing in at only 31kg, the M14T has been designed for use with the Mach M181T or M218T subwoofer.
As a dual 18" front-loaded subwoofer, the M218T is designed to support the Mach M14T or M30T. To achieve high quality sub bass reproduction while maintaining clarity, M218T has been designed as a bass reflex cabinet. The woofers feature a 4" interleaved sandwich voice coil with windings on the outside as well as the inside of the voice coil former. The result, say Mach, is a balanced coil with uniform distribution of mass and motive energy that provides an extremely linear motor assembly. In addition, the motor features the use of double demodulating rings, which nearly eliminate intermodulation and harmonic distortion while improving impulse and transient response.
In order to achieve maximum strength and reliability, the diaphragm is reinforced with carbon fibre. The design of the basket and the double spider offer excellent heat dissipation and thereby very low power compression.
