6.5" On Axis Frequency Response
The Drivers
Included in your kit are two each of the #295-305 6.5" Dayton mid-woofer and the #275-070 Dayton 1-1/8" silk dome
tweeter. Both units have been a hot bed of discussion on the Parts Express Tech Talk board and are good candidates
for this project. The woofer incorporates a treated paper cone, coupled to a rubber surround. The response is generally
well behaved, but does exhibit a peak centered around 3.3KHz.
The Dayton 1-1/8" silk dome tweeter is hands down one of the finest tweeters available in it's price range! The
response exhibits some peakiness, and the driver seems to have a ‘wandering’ Fs, but the sound is on a par with
tweeters that cost far more.
6.5" Impedance Sweep
The impedance is smooth, but due to the rather large amount of voice coil inductance, rises sharply. Note in the
2KHz area, where this driver will be crossed over, the impedance is 25 ohms. For this reason, an impedance compen-
sation network will be used.
