JBL 120Ti

Name: JBL 120Ti
Brand: JBL

The JBL 120Ti is a three-way, floor-standing loudspeaker from JBL's "Ti" series. The name comes from its titanium dome tweeter, a material JBL was promoting heavily in the mid-1980s as part of a broader push toward what Audio (August 1985, p.106) described as a return to fundamentals and an emphasis on accuracy across the line. Beyond that, the documented record on this model is thin.

Here is what the period specifications give. The 120Ti is rated at 8 ohms nominal impedance, with a sensitivity of 90 dB/W/m and a frequency response of 40 Hz to 25 kHz. The crossover points are 700 Hz and 3 kHz, which splits the band across the three drivers. Exact production years, original pricing, cabinet dimensions, and the woofer and midrange drivers are not documented in the available research.

It is a straightforward example of JBL's mid-80s engineering: titanium tweeter, sensible crossover points, respectable sensitivity. A collector looking for more detail on this model will find the paper trail quiet.
