GPA Maestro LogoOur 3000-series of Low Frequency Loudspeakers were specifically designed for sound reinforcement applications, and have also found their way into home theatre and many other types of systems. Outstanding performers, they offer extremely linear performance at low distortion within their rated bandwidth.

Each LF speaker in the 3000-series is designed for a specific application -

GPA 3184 WooferOur 18" Model 3184 Low-Frequency Loudspeaker is, quite simply, an fantastic woofer. Designed for use as a sub-woofer, when used in our Model 8184 Enclosure, it produces a whopping 117 dB of SPL with a mere 300 watts of audio power. Yet, with all that output, it is amazingly linear and exhibits very low distortion. Great for large sound systems and home audio systems where performance takes priority over space limitations.
