Bandpass Enclosure Design
Bandpass enclosures are extremely ecient, creating maximum bass output within a specic
frequency range by increasing the acoustic load presented to the driver. The low distortion
bandpass design utilised in the TLX212L reinforces the bass musical instrument frequencies and
steep cut-o slopes ensure an eective acoustic transition for use with TLX43 line array elements.
For low-frequency bass extension, the recommended cabinet ratio consists of one TLX212L
subwoofer per 3 TLX43 elements. For reverse cardioid subwoofer congurations, multiples of three
TLX212L enclosures are recommended with two front-ring enclosures and one rear-ring enclosure.
Acoustic Simulation Tools
EASE GLL les are provided for the EASE Focus Acoustics Simulation Software, which is available
for free download. This allows accurate calculation of both acoustic coverage and selection of
suspension pick point for tilting and aiming the array at the desired angle.
Construction and Connectivity
An integral suspension system engineered to meet BGV-C1 specications is provided for suspending
or ground stacking TLX212L and TLX43 elements with a 10:1 safety factor. Designed for speed and
simplicity of use, custom-engineered ybars and wheel boards are available as separate accessories.
Finished in hard wearing semi matt black paint, the cabinet is constructed from 15 mm (⁄")
birch plywood and includes a rugged powder coated perforated steel mesh grille backed with
reticulated foam. The rear panel connector plate carries Neutrik speakON* NL4 connectors for input
and link connections to additional enclosures.
