3Solo-baric L5 SubwoofersFeaturesFeatures SoloKön™ is an ultra high performance composite, whichremains rigid, minimizes cone flex and lowers harmonicdistortion. The SoloKön™ consists of a unique one-piece,aluminum vapor-deposit material that moves as a lightweight piston, exhibiting power and control. Rear Cone Brace integrates into the SoloKön™ with acontinuous contact perimeter weld, which offers unmatchedstrength and resistance to deformation under pressure. Increased Santoprene™ Surround Radius allowsextended cone excursion for additional bass output and higherSPL. Santoprene™ is the next generation of surround material.It offers unmatched UV protection and gives the SoloKön™maximum EXmax™ (effective excursion) potential. Stitched Surround adds a mechanical fastener to thechemical adhesives. This duo prevents the cone and surroundfrom separating in the harshest conditions. New Enhanced BAM (Basket and Motor) Assemblyutilizes a high strength steel basket, features a low-profile opendesign, and provides a solid foundation for theprecision-aligned motor assembly. Perimeter Venting in the BAM relieves pressure fromunder the spider, supports a linear excursion, and helpsdissipate heat from the voice coil and motor structure. Dual Ultra-Length Voice Coils sustain enormous coneexcursion and provide flexible impedance matching options. High-Temp Polyimide Film Voice Coil Formerimproves sonic and conductive properties, and preventsthermal-electrical meltdown. One-Piece Uniplate™ with Vented Hyper-ExtendedPole Piece and Backplate1. Optimizes heat transfer efficiency for cooler operationand maximum power handling ability.2. Eliminates erratic magnetic flux from the voice-coil gap.3. Releases pressure under the suspension for uniformcone movement and responsive low bass.4. Prevents the voice-coil from bottoming out andcorresponding damage. Sleeved High-Power Tinsel Lead Wires eliminatebroken leads and power loss, due to the common use of“insufficient-gauge” lead wires. The lead wires are terminatedwith multiple polymer-based strain-relieving mechanicalfasteners. Spring-Loaded Nickel Plated Terminals flawlesslyconnect medium to heavy gauge speaker wire to the sleevedhigh-power tinsel lead wires.
