Peavey Low Rider 18" Speaker

Features:

The Low Rider driver series represents a milestone in highpowered sub-woofer design. An incredible 1,600 Watt program rating and extra-long cone excursion provide maximum amounts of amazingly clean, deep bass. The Low Rider is a superior choice for the bottom end of any highpowered sound system, from DJ rigs to the largest professional touring shows. DESIGN The Low Rider utilizes a variation on the existing Kevlar®- impregnated cones used on all Black Widow® speakers. The cone is stronger and tougher and uses an innovative asymmetrical -M surround for superior excursion and motion control. High quality spring terminals accepting large gauge wire are attached to large diameter highcurrent tinsel leads with silver solder to withstand high currents, high temperatures and long excursion. The massive new voice coil uses polyimide-insulated copper ribbon wire, edge-wound and bonded onto an incredibly durable and heat-resistant polyimide composite former. The coil’s winding length of 1.150” is an amazing 80% longer than Peavey’s standard Black Widow coil. The long coil has a large surface area to dissipate heat, and its increased length drives the cone to a far higher excursion. The coil is over coated with a tough thermoset epoxy for added durability, abrasion resistance and heat dissipation. The coil wires are solderless diffusion welded to highconductivity OFHC copper ribbon leads, which are embedded inside the former assembly and soldered to the tinsel leads with high temperature silver solder. The solder joint is then coated with a special, thermally conductive silicone adhesive for encapsulation and heat dissipation. The voice coil assembly is bonded to the Kevlar cone and new, incredibly tough plastiseal-coated Nomex® progressive-roll spider using a thermoset epoxy originally developed for attaching nose cones onto ICBM missiles — truly an aerospace grade adhesive. The spider and surround are bonded to the frame with a strong, toughened cyanoacrylate adhesive, which is also used to bond the dust cap to the cone. The magnet structure is all new and was designed using extensive Finite Element computer modeling. The back plate/pole piece is cold forged from a single massive billet of ultra low carbon steel, included Peavey’s patented Focused Field Geometry and is undercut to allow greater coil travel. The pole is extended beyond the front plate to improve coil cooling and make it more magnetically linear and the front plate is 10mm thick to match the long voice coil and provide a better path for heat and magnetic energy. The result is 50% more total magnetic gap energy than can be found in the standard Black Widow Super Structure magnet assembly. A patent pending vent plate greatly improves voice coil cooling. This heat conductive, ported and finned aluminum ring delivers cool air pumped by the spider directly to the voice coil to keep operating temperatures under control. The improved cooling increases power handling and reliability and reduce power compression. The cast aluminum frame is tough and rigid and has the strength needed to hold the cone and huge magnet assembly in perfect alignment. The deep dish design and large spider clearance make high excursion and high output possible. These dynamic new drivers also utilize the user friendly Black Widow replaceable basket assemblies with Rubatex® gaskets.
