High Output Ported Enclosure
High Output Ported Enclosure Explanation
As the name suggests, the high output ported enclosure will play the loudest of the three designs. Its large internal
volume combined with large port area delivers great efficiency for very high output. Tuning is higher than the Sound
quality enclosure bringing the peak efficiency point of the enclosure much closer to average vehicle resonance but is still
tuned low enough for good musical reproduction.
