Unless you've been on active duty in the Middle East, you're aware that Mobile Fidelity Sound Lab is back in business. During Stereophile's Home Entertainment 2003 show in San Francisco last June, Kal Rubinson and I played hookey to visit MoFi mastering engineer Paul Stubblebine's recording studio, at 1340 Mission Street. As we sat spellbound, Paul played the original four-track, ½", 1-mil master tape of Stanislaw Skrowaczewski and the Minnesota Orchestra's legendary 1974 recording of Ravel's Boléro and Daphnis et Chloé (footnote 1). Stubblebine fed the four discrete channels from the specially modified ReVox reel-to-reel deck to a modern surround system. The master tape produced the cleanest, purest sound I had heard in a long time.

During visits to the suite, I also heard Jake Shimabukuro's ukulele playing, which was outstanding, and then a recording of his performance played back over the Nagra HD monoblocks…

JBL was founded 60 years ago, by Jim Lansing. Its history has been amply detailed in the book The JBL Story: 60 Years of Audio Innovation, by the late John Eargle's (JBL Professional, 2006). Although it is primarily known for its pro-audio loudspeakers, the Californian company has offered a steady stream of high-performance domestic loudspeakers to the home market, including the 1971 Paragon, the L100 bookshelf speaker, and the JBL 250Ti floorstander, all of which remained in JBL's catalog for 20 years. In 1990, JBL produced the Project K2 S9500 flagship speaker for the Japanese high-end market. The K2 Project culminated in the $60,000/pair DD55000 Everest system, with its cross-firing asymmetric horns, and the subject of this review, the Synthesis 1400 Array BG, was a spin-off from the K2 project. It features horn-loaded midrange and tweeters to attain a flat response out to a claimed 48kHz.

Carl Kennedy, director of JL Audio's Home and Professional Sales division, leaned forward and quietly asked, "Would you like to review our Fathom f113 subwoofer?"
