PDF Jl Audio 12w7 Anniversary Edition designed-from-scratch W7 subs. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\n\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. The problem with big surrounds is that they begin to encroach on the effective piston area of the driver. The W7's are built in the USA and the manufacture date on this one was 2/22/2018. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A. The obvious ones are using a thicker material and/or a stiffer material. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) Not only are its ingenious technical solutions impressive, but also its sonic abilities which leave no desire unfulfilled. The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. Never smelt a burnt coil or anything. To commemorate the occasion, each W7 model is now offered in special “Anniversary Edition” (AE) trim, with a satin black frame finish, a bright-anodized trim ring and special badging. Still have plenty of room to bump even harder but my 500 watt gets the job done nicely. Coverage may be invalidated as this date is previous to purchase date. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Prime Carrello. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Calculate ports as solid, not hollow objects.\u003c\/p\u003e\n\u003cp\u003e* The W7’s employ a pole vent to remove heat and pressure from the inside of the speaker.This vent is located at the rear of the speaker. This means that their use accepts the compromise of added moving mass on the design. This delivers intensely valuable information compared to traditional modeling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. The JL Audio W7 speaker sizes range from 8 to 14 inches in diameter without a housing or enclosure. ft. (38.9 l) sealed enclosure, or a 1.75 cu. Its main catalyst is the driver's Ultra-long Voice Coil, that allows extreme linear excursion, phenomenal power handling and control, control, control. Freight damage on returns is not covered under warranty. This improves power handling and reduces power compression effects, leading to more linear performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eThis technology differs from a conventionally vented pole-piece in that the air flow is capped off at the top of the pole-piece and directed through machined holes on the outer wall of the pole-piece to the region directly behind the voice coil. Another is ensuring that the leads do not short one another or the frame of the woofer. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area. Atrend JL Audio 12W7 Subwoofer Box (12W7SV), Bundle Savings of Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, \"big-picture\" solution.
