Sub Bass Enclosure

1x 18″ Sub Bass Driver | Class D Amplifier Module

The BB03.5A professional self powered sub bass loudspeaker system provides strong clean bass response with great sonic impact, while retaining warmth and definition well into the upper bass registers. The loudspeaker system employs an efficient, lightweight neodymium 18″ transducer in an optimally tuned and ported cabinet with a low frequency extension to 35Hz.

The BB03.5A is powered by a sophisticated Class D Amplifier Module complete with a fully integrated Switch Mode Power Supply and onboard Digital Signal Processing. BvNET hardware and Podware software provides complete control and monitoring of the BB03.5A´s amplifiers and internal DSP system and facilitates networking in multi-cabinet systems. Acoustic Technologies manufactures a wide range of loudspeaker systems which incorporate BvNET / Podware, allowing a fully networked system to be controlled and monitored from a single convenient location. For even greater capability Podware can be used as a plug-in with AFMG SysTune audio analysis software.

The BB03.5A is constructed from the highest quality 18mm & 24mm Finnish Birch Ply coated with Acoustic Technologies proprietary elastomer AcoustiCoate protective finish. A powder coated steel grille and pole mount adapter complete a robust, durable and versatile touring cabinet.

The Acoustic Technologies BB03.5A´s compact cabinet dimensions, high power handling and light weight make it ideally suited to all manner of professional audio applications including arena scale Touring Concert Systems, Dance Clubs, Cinemas and Houses of Worship.
