Isolde AP108a is a powerful, compact, active 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 AP108a to do double duty as a compact wedge monitor. A range of wall, ceiling and pole mounting options underlines Isolde AP108a’s readiness to perform wherever high SPL is needed in a small package.

Intuitive SCiO software enables remote control and monitoring of AP108a’s integral amplifier from any device.

Isolde AP108a is made in Belgium using birch plywood for peerless rigidity and audio transparency.
