Dayton BR-1 Crossover Question.

RDV · 6th June 2006, 08:35 PM

In the manual for the Dayton BR-1 they make this statement:

"The high pass filter is comprised of C1 and L1, and is also a electrical 2nd order yet it yields approximately a 3rd
order acoustic response. R2 and R3 attenuates the tweeter’s output 6 dB to match the woofer’s level."

How is this true without the second cap from a 3rd order network?
Is it because the pad resistors have some capacitance, or capacitive properties?

I'm thinking of sort of copying this crossover for a project and I don't understand how this is crossing at 2100HZ.

Thanks in advance.

I beleive the 3rd order response that the manual speaks of is the combined response from the crossover and mechanical effects from the enclosure.

The 3rd order acoustic response is the combined electrical 2nd order response and the driver's innate rolloff.
