Electro-Voice 409 Series Specifications

General Product Description
®
The Electro-Voice 409 series loudspeaker systems are
two-way loudspeakers with 8-inch low-frequency cones
and high temperature voice-coil assemblies coaxially
mounted with wide-dispersion cone tweeters. The dual
magnet construction allows each speaker to be structurally,
magnetically, electrically and mechanically independent of
the other. The 409 series utilize a single section crossover
network, centered at 2500 Hz, providing 6 dB of attenuation
for each element outside the operating range.
The 409-8E is an 8 ohm, 32 watt speaker. The 409-ST (with
15700 transformer) and the 409-4T (with 15704 transformer)
both offer a selection of 0.5, 1, 2 and 4W. The 409-8T (with
15708 transformer) offers a selection of 1, 2, 4 and 8W. The
409-16T (with 15716 transformer) offers 2, 4, 8 and 16W
and the 409-32T (with 15732 transformer) offers a 4, 8, 16,
32W selection.
