Sealed Enclosure Explanation
A sealed enclosure is the best option if sound quality is of primary concern. It will offer the best
overall response across the low frequency audio spectrum, great transient response, and will allow for
the most seamless integration between the subwoofer system and front speakers. It is also half the
size of the sound quality ported design minimizing the space that needs to be dedicated to the
subwoofer enclosure.
