Preface:
Sporting dimensions of 9.5" x 43.5" x 16", with an internal volume of 90 liters. In spite of its relatively low Q the MLTL provides impressive low end extension, with a modeled f3 of 40 Hz, and an f6 of 30 Hz.
Certainly they provide sufficient extension and SPL for most civilized music reproduction.
How do they sound? Like a gravitational singularity, they draw you in.
