The team at JL Au­dio in­vited us down to check out their mon­strous pro­duc­tion fa­cil­ity in Mi­ra­mar, Florida, where they build, as­sem­ble and ware­house their speak­ers, en­clo­sures and Stealth­box fiber­glass en­clo­sures. While we were in Florida we were also among the first to see and hear the com­pany’s new VXI amplifiers with built-in, high-end DSP ca­pa­bil­i­ties for au­dio­phile sound qual­ity in vir­tu­ally any car or truck in a small and ef­fi­cient am­pli­fier.

Each am­pli­fier is equipped with a cus­tom­ized, triple-core AKM DSP en­gine to pro­vide a com­plete suite of DSP set­tings and op­tions, in­clud­ing cross­over and equal­iza­tion set­tings as well as time align­ment. Tun­ing is han­dled on a com­puter, lap­top, tablet or smart­phone us­ing JL Au­dio’s TÜN soft­ware. One, two, four, five, six and eight-chan­nel mod­els are avail­able in power out­put lev­els from 400 to 1,000 watts to power com­po­nents, sub­woofers or a com­plete sys­tem with one or mul­ti­ple amplifiers. We were able to lis­ten to three dif­fer­ent sys­tems in demo ve­hi­cles in­clud­ing a Cadil­lac CT6, Jeep Chero­kee and Ford F-150; all three of the ve­hi­cles used the fac­tory head units in­te­grated with the new VXI amplifiers di­rectly. Now that the Su­per Duty shares cab con­fig­u­ra­tions with the F-150 and know­ing that an F-150 diesel will be com­ing down Ford’s assem­bly lines soon, we paid spe­cial at­ten­tion to the truck. With two small amplifiers mounted be­low the seat along with a Stealth­box en­clo-

sure and JL’S C7 3-way com­po­nents in­stalled up front, the sys­tem sounded great and of­fered in­cred­i­ble dy­nam­ics with au­dio­phile-level stag­ing and imag­ing thanks to the DSP tun­ing built into the VXI amplifiers.

While tour­ing the fa­cil­ity we saw the speaker pro­duc­tion lines as well as the fiber­glass and wood shops where the stan­dard and Stealth­box sub en­clo­sures are built. We also saw the ware­house and ship­ping fa­cil­i­ties that al­low JL Au­dio to ship its prod­ucts to deal­ers around the world and to en­thu­si­asts like us. If you are look­ing to up­grade the sound sys­tem in your diesel truck, be sure to give JL Au­dio a look and lis­ten be­fore mak­ing your pur­chas­ing de­ci­sion. UDBG

JL Au­dio’s fa­cil­ity in Mi­ra­mar, Florida, houses speaker and sub­woofer man­u­fac­tur­ing, en­clo­sure and Stealth­box pro­duc­tion, and ware­hous­ing, sales, R&D and train­ing fa­cil­i­ties at the sunny south Florida lo­ca­tion.

Us­ing a heat gun and high-qual­ity car­pet, this em­ployee care­fully wraps and molds the car­pet to the Stealth­box en­clo­sure be­fore the sub­woofers are loaded into it at an­other sta­tion.

In the fiber­glass shop, techs hand-lay the fiber­glass mat in the molds to make the fa­mous Stealth­box ve­hi­cle-spe­cific sub­woofer en­clo­sures, which are a di­rect fit in many pop­u­lar ve­hi­cles, in­clud­ing sev­eral of our fa­vorite diesel trucks.

Even the small ba­sic sub en­clo­sures are hand-made here in the JL Au­dio fa­cil­ity. Here, an em­ployee loads a sub­woofer into the en­clo­sure that was car­peted and as­sem­bled at pre­vi­ous sta­tions in the assem­bly line.

All eight of the new VXI amplifiers were on dis­play at the JL Au­dio train­ing event we at­tended. The line in­cludes 600- and 1,000-watt monoblocks, a 600-watt 2-chan­nel, 400-watt 4-chan­nel, 600-watt 6-chan­nel, 800-watt 8-chan­nel and 700- and 1,000-watt...
