The TrueLine TL218SS is designed to satisfy the need for an extreme high-SPL sub bass loudspeaker system. Components have been selected solely for their performance.
The TrueLine TL218SS utilizes a direct radiating 18-inch, 4,000W cone driver in a tuned enclosure, which provides maximum output with minimal distortion and smooth extended low frequency response. The tour tested 21 ply Baltic Birch highly braced enclosure and 24 mm thick baffle board construction provide unsurpassed rigidity and strength.
Built to last.
The enclosure is built to truck pack dimensions for efficient transportation of multiple units, and should be arrayed to increase performance in large or outdoor venues. The TrueLine TL218SS is designed to be used for low frequency sections in multi-way speaker systems, or as a sub bass section in any sound system requiring extended low frequency response and the highest quality audio reproduction.
The TrueLine TL218SS comes with a multi-layered catalyzed Polyurea finish and is offered with a variety of color options. The TrueLine TL218SS delivers the transparent sonic quality and easy portability necessary for the demands of professional audio today.
