Selecting An Enclosure - Soundstream RUBICON 10 Owner's Manual And Installation Manual

SELECTING AN ENCLOSURE

There are several different enclosure designs for different applications.
The RUBICON subwoofers work very well in all the following enclosure
designs. It is up to you to select the specific enclosure that will work
the best for your particular application.
Infinite Baffle
Infinite baffle is the simplest type of subwoofer installation. In this type
of installation, the woofer(s) is mounted to a baffle which is then
mounted to either the rear deck or back seat of the vehicle. The best
results are achieved when the trunk area is virtually airtight and
isolated from the passenger compartment.
Pros
• Excellent low frequency extension
• Excellent transient response
• Uses almost no trunk space
Sealed Enclosure
Sealed enclosures are relatively simple to build and
install, as all that is required is an airtight box. The
larger the sealed enclosure,
performance resembles that of an infinite baffle
Pros
• Very good low frequency • Medium efficiency
