Re: The French Bulldog - Tang Band W6 PR micro-sub

Oh, what did I start? ;) I gave you this formula to show you the relationship of the different components that make up this formula and how they affect each other.

It is not possible to generically use this formula to come up with an answer as to the precise value needed to achieve a certain x-over frequency as that depends upon the impedance profile of whatever follows. That said, your calculations are correct. If you are trying to achieve an 4 Ohm impedance at 80 Hz, 500 MFD would be required and for a 6 Ohm impedance at 80 Hz, 333MFD.

Just experiment by ear by plugging some different caps into the circuit and settle on what sounds good to you. The process is not that critical. It is similar to dialing in the right amount of bass assistance from your subwoofer. You increase the level to where it sounds good. You normally don't take measurements or perform calculations when you do this.

If there is an easy way to insert the capacitor in the circuit as Wolf suggests, so much the better. Start with a cap of 150MFD as he suggests and go up from there.
