Thank you for your support of Kicker products, and especially our Solo-Baric® L7 (patent pending) square sub-
woofers. The SL7s are truly unique products in a world of round subwoofers. Our technical and R&D staffs have
designed some extreme enclosures beyond the small sealed boxes Solo-Barics are famous for. They have
unleashed the awesome capabilities of the L7s.
In this paper we will explore some applications for the Solo-Baric® L7 complete with box drawings and cut sheets
plus some important information regarding the break-in period for this ground-breaking speaker.
Important Break-In Information
Due to the complex nature of the Solo-Baric® L7s they require a little extra time to break-in. Especially in sealed
enclosures, break-in is a must in order for woofers to produce optimum low bass response. Due to the high per-
formance suspension system incorporated in the Solo-Barics they are very stiff “out of the box”. Approximately
two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. The “broken-in“
sub will exhibit stronger bass performance, smoother response, and greater low bass extension.
For those of you with more sophisticated audio equipment, the Solo-Barics can be broken-in on the test bench
overnight with the following procedure.
Solo-Baric Freeair Break-in Procedure
1. Connect the speaker to a power amp of about fifty watts or more. The speaker should not be mounted in any
enclosure - just freeair.
Please make sure it will not walk off the bench while it is playing!
2. Connect an audio generator to the input of the power amp, and adjust the generator to approximately 45Hz for
the S8L7, 35 Hz for the S10L7, 30 Hz for the S12L7, and 20 Hz for the S15L7.
3. Now adjust the gain on the amplifier and generator so that the cone is moving to Xmax. This can be determined
visually by looking at the “blur depth” of the logo on the ISD. A close approximation will do. On the S8L7 this will be
about 3/4”, on the S10L7 about 1”, on the S12L7 about 1”, and on the S15L7 about 1 1/4”.
NOTE: Keep in mind that as the speaker is used under normal conditions the break-in will continue, so if you don’t
have time for the complete break-in period the speaker will still break-in itself under normal usage.
