HERTZ EBX 250.5 Bass Reflex Sub Box

$329.99 USD
EBX 250.5

Designed to provide bursting dynamics and to minimise size requirements, EBX 250.5 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.
