•
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 & 146 Series) & 1.4 oz. (145 Series).
