The TrueLine X115 is designed to satisfy the need for an extreme high SPL extended bass loudspeaker system. Components have been selected solely for their performance.

The TrueLine X115 utilizes a single direct radiating 15” 1000W continuous power handling cone driver in a tuned enclosure, which provides maximum output with minimal distortion and smooth extended low frequency response.

The tour-tested 13 ply Baltic Birch highly braced enclosure and 15mm thick baffle board construction provide unsurpassed rigidity and strength. 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 X115 is designed to be used for low frequency sections in multi-way speaker systems.

All X-Series or bass section in any sound system requiring low frequency response and quality audio reproduction can use the TrueLine X115. The TrueLine X115 comes with a multi-layered catalyzed Polyurea finish and is offered with black and white as color options. The TrueLine X115 delivers the transparent sonic quality and easy portability necessary for the demands of professional audio today.

“The new sound system makes a world of difference. No matter where you sit, the sound is clear and consistent. The system does a great job reproducing music and, equally important, every spoken word is easy to understand. Music is very important at this church and the system really helps make services relevant to everyone in attendance. We couldn’t be happier.”
