Thank you for your support of Kicker products, and especially our Solo-Baric ® L7 (patent pending) square sub- woofers. The SL7s are truly unique pr oducts in a world of round subwoofers. Our technical and R&D staf fs have designed some extreme enclosures beyond the small sealed boxes Solo-Barics ar e famous for .
Sealed Enclosure Applications The Kicker Solo-Baric ® SL7 woofers are designed to give more output than an equivalent r ound speaker . The SL7 is amazing when used in the recommended sealed boxes. These sealed enclosure SQ r ecommendations will give the smoothest response with the most energy at r eally low frequencies, around 20 to 30 Hz.
Characteristics of Sealed Enclosures The most basic and simple of all speaker enclosures is the sealed box or acoustic suspension design. The acoustic suspension design has several advantages; it is easy to build, easy to tune and of fers high power handling, tight response and extended low end output.

P orted/V ented Enclosure Applications Ported Solo-Barics incorporate massive slot loaded ports with ultra low air velocity for ground pounding street bass that will make your hair stand on end (if you have any left)! These are the enclosures of choice for outrageous street bass and high performance SPL contests.
Characteristics of V ented Enclosures A vented enclosure is not much more complex than a sealed box. It consists, basically , of a box with a hole in it. However , despite its simple design, vented boxes are considerably harder to get good performance from than sealed boxes - although many times the extra ef fort can be worth it.

All the cubic feet numbers given in the supplied charts include the displacement of the woofer . For the port- ed boxes the displacement of the port must be added to the final design. It will be impractical to use round ports for these designs. The rectangular port information given will yield the best r esults.
