RE: FE208ES-R & T900a Specifications

Tom

It looks like it's time for some Cowboy Engineering: try it, see what happens. You can get good quality audiophile XO caps from MCM or Parts Express for not much money. In spite of the nay saying I have been doing regarding this, one thing which will let you pull it off is the very good impedance behavior of the T900 shown in the graph here. This is typical for a horn loaded driver. As a contrast, imagine trying the same trick on the FE208ES, that is to say using a series cap with the intention of attenuating the driver a few dB so that it can match a subwoofer you happen to have at hand. You will run into that rising impedance mountain that peaks at the 38 Hz Fs and goes way past 64 Ohms, in addition to the rising impedance toward the treble end due to voice coil inductance.

Anyway, let us know how it goes.
