• 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 our 148 & 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 Series) & 1.4 oz. (145 Series).
