  • Page 2: Features

    Mica Filled Polypropylene with a Titanium Deposit Coated Cone An Ultra High Performance look that makes the Solo-Baric® L7 truly a statement piece. The cone gives you deeper and stronger bass at higher listening levels with less distortion due to less tendency to flex. Because, when a woofer cone flexes, there is a loss of out- put.
  • Page 3 ISD (Inverted Structural Dome  ) ) Kicker was one of the first companies to switch to the Inverted Structural Dome. We have designed a cone with a groove for the ISD to lock into, further adding strength to structure. When a cone reaches it’s peak it wants to buckle because it’s momentum keeps it moving out.

  • Page 6: Sealed Enclosure Applications

    Solo-Baric® L7 series woofers also perform well in any sealed enclosure between the Compa a ct and SQ sizes. These systems will exhibit some benefits of both (high impact and low extension) generally sounding more like the box to which they are most closely sized.
  • Page 7 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 offers high power handling, tight response and extended low end output.

    We’re talking truly awesome. If space is not at a premium and you want to get the most from your Solo-Baric® L7, try one of these designs. You won’t be disappointed. Note: You must add the port volume to the volume of the box! See the cut sheets.
  • Page 11 The trick in building a vented box is to get the right size enclosure and the right size vent. You can’t be to far off on either of these factors or your speaker’s performance will suffer. In particular, using a too-small box or a too-high vent tuning frequency can eliminate bass instead of increasing it.
