The different projects


I used the nonmatched 1 and 4 horns for the actual loudspeakers. The serial resistor is a 15 ohm and the parallell is a 4W 8 ohm. For a more high power application a higher rated resistor would be better. The serial caps are 2.2µF vintage electrolytical bipolar 50 Volt types. That is hardly the limiting factor in this setting.

When measureing the impedance the pair matching is very good and the tuning is at 40 Hz, I will make some measurements of frequency response as soon as it works with the WAF.
