TDL Electronics RTL 1


The TDL RTL 1 are full 'reflex transmission line' loudspeakers, yet within enclosures sufficiently small to be considered bookshelf speakers.

Equally suited to that position, or placed on stands, they possess the sonic stature and power handling of much larger speakers.

Indeed, the aural illusion of the RTL 1 is of far greater sound sources, thus making them an ideal complement for the RTL 2 or RTL 3 in a surround system.

Amongst other speakers, the TDL RTL 1 should be the first to be auditioned.
