BANDPASS ENCLOSURES WERE THE MAGIC BOX FROM THE LATE '80S THROUGH THE '90S, BUT AT THE TURN OF THE CENTURY THEY BECAME ALL BUT OBSOLETE

摘要

They were a finicky bunch and Had 'to be designed with great precision. This required a good dose of mathematics and an understanding of how bandpass enclosures respond acoustically to a vehicle environment. When done correctly, the output gain of the sub could be substantial, often offering three to five decibels of gain over the same woofer in a sealed enclosure, and sound quality that was fairly uncompromising. In retrospect, bandpass enclosures were often significantly larger than a sealed box, and therefore less desirable. But the single largest contributing factor to their abandonment came with technological advancements in speaker design that allowed newer subs to work in ever-smaller enclosures with greater efficiency.
