AR (Acoustic Reality) series xo... some theory please

[john k...]

Any one have the study done by John Krevs?

I found this link for my old web page in the internat wayback machine. Some figures are missing bu the discussion is there.

Thanks John K,

But the main question remains.

With a 4ohms woofer its possibel use AR SXO in capless version?

Will the impedance see by the amp drop to much?

Yes it will, we know it now.

(Resistor *woofer impedance)/ (resistor + woofer impedance)

Have any of you fine gentleman used dual woofers in series for a three way ar sxo?. I have tubed gear which will not run dual woofers in parallel.

If my LEAP program calls for an inductor of 18mH for this series pair of woofers, can I use this as my starting point for L3?.

Last question; I notice on a few diagrams there is a resistor in parallel with one of the inductors, why?.

I think is bafle step compesation.
