The frequency response of a 209 in a typical 0. 25-cubic-foot and 1. 8-cubic-foot back enclosure are shown in Figure 1. Mounting The 309 may be front- or rear-mounted against either surface of its mounting flange and requires a 18. 4 cm (7. 25 in. ) diameter cutout and a 19. 5 cm (7. 68 in. ) bolt circle. Normal fasteners up to 5 mm (0. 20 in. ) will fit through the eight holes in the frame. The 309 is designed for mounting on standard ceiling speaker baffles. Figure 1, One-Third-Octave Polar Response Charts Measurements were made in a 1. 5 ft3 closed enclosure. 309-4T 25V 4. 0W 2. 0W 1. 0W . 05W Common 8 Ohms Common Brown Red Orange Yellow Black White Black 70V Yellow Green Blue Violet Black White Black 100V Green Blue Violet N/A Black White Black 309-8T 70V 8. 0W 4. 0W 2. 0W 1. 0W Common 8 Ohms Common Brown Red Orange Yellow Black White Grey 100V Red Orange Yellow N/A Black White Grey Wiring Diagam Dimensions Distortion Beamwidth vs Frequency Impedance Response Amplitude Response Directivity and Q 309-4T, 309-4TWB Power 0. 5W 1. 0W 2. 0W 4. 0W 8. 0W 10, 000 ohms 5, 000 ohms 2, 500 ohms 1, 250 ohms N/A 70V Yellow Orange Red Brown N/A 100V 20, 000 ohms 10, 000 ohms 5, 000 ohms 2, 500 ohms N/A Green Yellow Orange Red N/A 309-8T, 309-8TWB 70V N/A 5, 000 ohms 2, 500 ohms 1, 250 ohms 625 ohms N/A Yellow Orange Red Brown America: USA: Telex Communications Inc. 12000 Portland Ave South, Burnsville, MN 55337, USA, Phone: 952-884-4051, Fax: 952-884-0043 Western Canada: PAG Canada. 23 Hawkesbury Crescent, Winnipeg, MB R3P-1Y6, Canada, Phone: 888-850-8811, Fax: 204-489-7614 Eastern Canada: PAG Canada.
