In professional auditorium, stage, and event sound systems, the speaker driver plays a vital role in determining overall quality and performance. Among the most respected brands in the professional audio industry is Eighteen Sound - an Italian manufacturer renowned for its advanced technology, exceptional durability, and precise sound reproduction.

In today’s modern context, the need for public communication remains, yet expectations have evolved -requiring better sound quality, durability, and aesthetics. Now, the spirit of those traditional loudspeakers has returned in a completely new form: FBT horn speakers.
