6962, Viganello

Marvelous sounding vintage JBL speakers from the early 70s. This beautiful speaker was made for studio sound.

They feature a 2-way system with:
- compression drivers type 2420 with 2307 acustic lens for maximal dispersion
- 15woofers 2215B (just been REFURBISHED by audioconika with original JBL spare parts)

This combo delivers powerful dynamic sound with exceptional clarity and wide dispersion. You are gladly invited to come listen to them over a coffee!

Originally designed for studio use, they offer high sensitivity (~97 dB), making them easy to drive while producing great dynamics. Frequency response reaches approximately 40 Hz to 20 kHz, with tight, punchy but refined bass and detailed mids and highs typical horn systems. The 2307 lens provides excellent dispersion, creating a wide and immersive lively experience (concert like).

Housed in a large, solid cabinets (~39 kg each), beatifully painted grey, these speakers are built as professional equipment and remain highly sought after by collectors (especially by Japanese audiophiles!).

A rare opportunity to own an authentic piece of JBL history with that unmistakable vintage studio sound.
