Designed to provide bursting dynamics and to minimise size requirements, EBX 300.5 car audio subwoofer box result from long studies about car compartment acoustics. These boxes have an inclination wall; they are made of very thick MDF, in order for them to be inert and stable. Xponential Flanged Duct is a proprietary raccord style vent, reducing air turbulences to a minimum. The terminals were designed with special attention paid to ergonomics and efficiency. They are flush mounted into a milled recess in the enclosure itself, improving the integrity of the installation. Thanks to their unique pressure contact design, a low resistance transfer of power is ensured, without damaging the exposed wire strands. Two ergonomic handles, covered in anti-slip rubber, aid in the removal of the enclosure from the vehicle and the ease of its transportation.
