Anyone seen or heard a pair of these? Please share your views and comment.
Frequency Response 33Hz to 40KHz. Very heavy. Top scale at 90 KG per piece. Understand they are suppose to be a close "cousin" of the K2 S9800.

Since they do sport the blue fronts these are professional units. Perhaps some type of studio monitors. Could be a Japan only type system! Cheers

Not sure why JBL does this -- but another instance where a USA Made JBL speaker isn't available in the USA. I heard these were going for the equivalent of $12K a pair in Japan (1.6M Yen at the time).
Here's a blurb on them: "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." Bob
