The TrueLine TL.118SS 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 TL.118SS utilizes a direct radiating 18” 2000W 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 24mm 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 TL.118SS 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 TL.118SS comes with a multi-layered catalyzed Polyurea finish and is offered with a variety of color options. The TrueLine TL.118SS delivers the transparent sonic quality and easy portability necessary for the demands of professional audio today.

“Everyone at the church—including the clergy, music staff, and the congregation—has been extremely enthusiastic. The sound quality from the Worxaudio loudspeakers is clear and even no matter where one happens to be seated. The pastor, choir, and others on stage can hear clearly. Combine all this with a first-rate visual presentation and you have a recipe for success.”

“We’ve received a huge number of compliments from both church management and the congregation. No matter where you walk, the sound coverage is crystal clear and even. WorxAudio’s TrueLine X5i-P is a really unique line array system that offers tremendous bang for the buck and the TL118SSi-P subwoofers output a tremendous amount of low-end punch you have to feel to appreciate.”

“Both the administration and the faculty are really pleased with the new system. For the first time, people are able to understand what’s being said and when music is played, it sounds natural. The X1i-P’s dispersion is really wide and delivers consistent coverage throughout the room. With the school year’s assorted functions, everyone is looking forward to being able to understand every word!”

“This X1-P is very smooth sounding when crossing the room from left to right. The same cannot be said of many competing line arrays in this price range. With the X1-P, you hear clearly off-axis, and when you’re on-axis, the system doesn’t bombard you with high frequency harshness. It’s a very natural sounding system that isn’t the least bit fatiguing.”
