Above is an illustration of the new JBL 4348 Studio Monitor. This is the replacement for the 4344MKII. It adapts new technology developed for the K2-S9800 in the same configuration as the 4340 series monitors. In other words, it is a four-way system with a 15" bass driver, 10" mid bass, compression driver mid and compression driver UHF.

The bass driver is the new 1500Fe which uses the same basket as the 1500AL with a ferrite motor. Midbass is handled by the 10" pro 2251J which uses a differential drive motor. The midrange compression driver is the 435AL which is a consumer conversion of the 2430. This is the same motor as the 2435/435Be but uses an aluminum diaphragm instead of beryllium. The acoustic lens is gone, replaced by a small biradial horn. The UHF is the same 045Be from the S9800. Pricing in Japan is rather high at 16,000,000 Yen or around $12,000US/pr. No word yet on whether this system will be made available domestically.

The photo is extracted from the current "Summer 2002" issue of Stereo Sound Japan. The text is in Japanese, but there are a number of illustrations of the various components and construction details. Since this issue is just hitting the newsstands, I won't be publishing any further illustrations from that article. If you are interested in more details, it is worth ordering a copy of this issue from Stereo Sound at this link.
