Active Crossovers

I have the horn and the 10 inch on the stock crossover. That crossover seems to have a capacitor and resistor to the 10 inch. Isn't that cutting the low frequency off?

Ist that your stock crossover, are my assumptions correct?
Are the drivers connected correctly?


A phase plug for 10" is difficult and has a greater influence than you think. I would search the internet for wooden buttons that close the central hole (dust cap)

P.S
Analyzing a crossover without having it in hand and drawing a circuit diagram is very difficult. It can be notchflter, zobel network and different edge steepness in this xover.

I don't understand???
Isn't there a difference between how low a frequency a driver can reach based upon its size and how its mounted, and the space it in. VS How much energy a amplifier is spending to send power to the driver at all frequency levels.. In other words, even though the driver can not produce sound below 120 hertz in a baffle, the amp might still be giving it as much power as it can to produce a 30 hertz tone. Essentially that ends up being heat and distortion.

Of course the amplifier also reproduces 30hz, but if the speaker has a sound pressure of -20db than at 120hz, that's no longer a load. If you want to free it from bass there are two options: active xover or reducing the size of the coupling capacitor in the tube amp
