I agree that this is fundamentally science. But for the layman to pick up and build a speaker without a degree requires some shortcuts in the knowledge. Nevertheless, on ejp's advice, I did find a design that replaced the L-pad with a series resistors after the crossover that is a modest value that preserves a good response. 8 ohm filter impedance on both low pass and high pass, 2500hz crossover, and only the series resistor to ground after to attenuate the woofer. What did I screw up here:
That mostly explains the origin of the thread, which isn't the First(and won't be the last).acoustic matters
To understand the baffle step concept you must know what an enclosed woofer produces, in terms of sound field
Or Just consider the emission in half space, same as positioning the speakers baffle in the wallTo understand the baffle step concept you must know what an enclosed woofer produces, in terms of sound field
Please tell us what the graphs are purporting to show.
And you do realize there is no such thing as a 1.06uF capacitor? And that for the same cutoff frequency you can use the same L and C values in both crossovers, just interchanged as to series and shunt?
And 'series resistor to ground' is a contradiction in terms. I thought you said you had a good background in electronics? Your 1-ohm SHUNT resistor will blow up the amplifier.

Yes, theory says that. but the load Is different: Just compare the voice coil assembly of a woofer and a tweeteruse the same L and C values in both crossovers, just interchanged as to series and shunt?
Well...er...and the acoustic resistance that the associated membrane seesYes, theory says that. but the load Is different: Just compare the voice coil assembly of a woofer and a tweeter
