Isolde AP108x is a powerful, passive, compact point source loudspeaker with the versatility to excel in countless short throw live and installation scenarios. A premium 8” LF transducer incorporating Tetracoil technology ensures best-in-class SPL and massive headroom. The chosen neodymium magnet 1.4” exit throat / 2.4” voice coil HF transducer is from the exceptional family of drivers employed in our flagship touring series, sharing the same acclaimed intelligibility and audio signature across the range.

As a 2-way loudspeaker, Isolde outshines rival coax designs with superior control and directivity. This precision is augmented by a custom engineered, 3D printed horn concept, enforcing rigid control over the speaker’s coverage pattern.

The ability to quickly rotate the horn through 90°, coupled with its unique cabinet shape, allows AP108x to do double duty as a compact wedge monitor. A range of wall, ceiling and pole mounting options underlines Isolde AP108x’s readiness to perform wherever high SPL is needed in a small package.

Isolde AP108x is made in Belgium using birch plywood for peerless rigidity and audio transparency.
