High performances multi-purpose

Two-way bass-reflex
1 x 15" Neodymium cone driver
HF driver 1.4''


The APG SMX15 is a two-way coaxial speaker offering high performance as well acoustically as ergonomically. The low frequency section uses a new generation neodymium 15" cone speaker mounted in a ported enclosure.

This new loudspeaker takes advantage of a proprietary technique of forced thermal transfer, which drastically reduces thermal compression effects, resulting in exceptional sound pressure capacity down to 60 Hz. The high frequency section uses a neodymium compression driver offering extremely low distortion and frequency extension up to 20 kHz. The specific shape of the cabinet, combined with the unique AST (Aiming Tuning System) allow the speaker to be tilted at 5 different angles, each position offering the lowest possible profile. A total of three integrated handles answers all needs in terms of lifting and handling.

Like the other speakers from the Dispersion Series, the SMX15 uses the coaxial technology which confers a perfectly coherent sound field to it on a conical dispersion of 85°. Connectors are located in two recesses, one on each side, providing protection when in use. The frequency and phase response of the SMX15 are perfectly linear, resulting in exceptional feedback reduction. The SMX15 operates in bi-amplification only, with a dedicated active processor DMS48F. For low frequency extension, use APG subwoofers series.
