Audio Chassis Mount
143-146 Series
Features
Small, economical, open, two hole horizontal bracket mount.
Insulated, color coded flexible leads, 4" long minimum (143, 144 & 145
Series) or 3" long minimum (146 Series).
For a similar, P.C. board mount version, refer to the 148 and 149 series.
Frequency response 150 Hz. to 15 Khz. (+/- 1 db, reference 1000 Hz.)
When operating at impedances below nominal, power capability and the
frequency spectrum are proportionately lower, conversely, at higher
impedances power capability and frequency spectrum will be
proportionately higher.
Net weight: 0.5 oz. (143, 144, 146 Series) & 1.4 oz. (145 Series).
