Reflex Transmission Line Loudspeaker

TDL Electronics RTL 3


Two bass units within these 'reflex transmission line' loudspeakers further enhance bass performance, contributing to increased sensitivity and additional power handling.

The TDL RTL 3 is the perfect partner for a larger room. Retaining the fine stereo imaging of their smaller counterparts, room position is not critical, neither are they difficult to drive.

Indeed, they possess the ability to portray accurately the original performance at realistic sound levels, especially when coupled with powerful amplification.
