JBL 3106
The JBL 3106 is a compact two-way loudspeaker from JBL's consumer line. The exact production years and original pricing aren't documented in the surviving record. What is known comes mostly from period equipment listings. It pairs a 200 mm woofer with a 25 mm dome tweeter, crosses over at 2500 Hz, and is rated at 50 watts maximum power with 88 dB sensitivity. Both hifi-wiki.com and vintagewiring.com agree on a frequency response of 58-20000 Hz and 8-ohm impedance.
The cabinet is bookshelf-sized at 26.7 × 46.4 × 22.9 cm and weighs 9.1 kg. It has simple two-screw terminals and a dust cover over the front. The sources disagree on the enclosure type. One lists it as closed (sealed), another as bass reflex, and without a manufacturer manual nobody can settle it. The unit came with mounting hardware and a 2-meter cable.
Beyond the basic specs, the record is thin. No period reviews, owner commentary or word on where it sat in the JBL lineup have surfaced. A single Canadian listing from a private seller asked $195 CAD for a "very good" pair with grilles, original manual and one-owner history. That at least confirms these were sold with fabric covers and that a manual exists, even if nobody has digitized it.
