Installation
The Space subwoofer can be installed in a variety of different ways, the most suitable will depend upon your application.
Free-air installation
The VIBE Space Subwoofer can be mounted free-air, but this does not mean that the woofer can work without any form of
enclosure. What it does mean is that the enclosure can be very large and therefore the subwoofer can utilise the vehicles boot as an
enclosure.
The Subwoofer needs to be mounted to a rigid panel as excess vibration will result in poor sound quality. The panel or baffle, should
also seal the output from the front of the Subwoofer from the output from the rear otherwise poor sound quality, known as phase
error, will occur. This simply means that the output from the rear of the woofer will cancel out the output from the front resulting in a
loss of bass.
As the enclosure in free-air applications is so large it is worth noting that the power handling of the Subwoofer is reduced to half that
of the same woofer in a measured enclosure. Please take this into account when choosing your amplifier.
The sound quality of a free-air mounted Subwoofer will not match that of the same subwoofer mounted in a measured enclosure.
However in applications where building a traditional enclosure is impossible, free-air mounting will add increased bass response to
your system.
