Kicker Ships L7T Thin Square Sub

Kicker-L7T

Press Release (Unedited): STILLWATER, USA – KICKER® has combined the mounting flexibility of a thin, true subwoofer to the added cone area of its iconic Solo-Baric® L7® square subs.  Six models of this new L7T™ Subwoofer line have now begun shipping to Authorized Dealers in the United States and are available both in-store and online.

The unique square cone provides up to 20% additional cone area compared to a standard circular sub of the same size, making a 12-inch square sub perform like a 15-inch round subwoofer, without requiring a larger frame or motor. The consumer enjoys more volume, deeper bass and greater overall value, and in the case with the L7T, the ability to fit into the trickiest installations with its thin design.

The extended top plate has a patented “bumped” design, allowing extra excursion and long throw for deeper overall bass, despite its shallow makeup. KICKER’s UniPlate™ combines the pole piece and backplate as a single, seamless unit meant to pull damaging heat away from the sub. Perimeter venting is also used above the top plate, bringing additional cooling air in and around the motor.

KICKER’s SoloKon™ technology employs an injection-molded polypropylene square cone and 360-degree back bracing as a single solid unit. The unique design assists in both cooling the motor and eliminating distortion. Patented ribbed corners are incorporated into the high-roll Santoprene® surround.  The corners allow the square suspension to move smoothly under high SPL requirements, providing a loud, accurate response. KICKER then stitches the cone to the surround, providing an additional level of integrity.

  1. Our claim that a square 12″ woofer performs like a 15″ round was very bad math on our part. Please accept our apologies. The correct math is that any square cone with the same dimension across as a round cone will have 27% more cone area. We deduct a percentage for some rounding in the corners of a square cone, so our standard statement is that the square has up to 20% more cone area than a round cone. I hope this helps.

  2. I would have to concur. A typical 15 sub will have 120 – 132 sq. in of cone area, which is approx 50% larger, compared to an average 12 has.
    So 20 – 25% increased cone area, which is very similar to typical 13” piston area (100 sq. in), willl only offer very modest increase in output, and simply not come close to what 15-in cone surface area provides…

  3. Really? Thats an amazing bit of disinformation there —
    The SD (cone area) of a 15” sub is at least 50% greater than ANY 12” woofer.
    So even IF the cone area of a square driver is 20% more (vs. round driver), which
    it absolutely is NOT, then the purported math claimed here is both 30% ‘short’ and
    totally bogus.
    So the fact is, no 12” L7 driver will perform even close to “like a 15” round subwoofer.”
    Enough!
