Higher inductance prevents the amp to control easily the cone. When we connect an extra inductance (the second driver) in series with the first one, doenst the total inductance shown to the amp increase? Btw check out this link

Default nice link

cool link some good information there although the fourth paragraph is wrong; the force generated on the VC has nothing to do with the magnetic field generated by the current in the VC but instead by the simple fact that moving a current through a B field generates a force iL cross B or maybe vice versa.

It is interesting when dealing drivers needing high transient speeds ie. tweeters. Any high trasient signal is created, if we look at it in the frequency domain, by a large amount of high frequency informationwhich is filtered off by the cross overs.

Further significance is that for mid base drivers and mids there is an inductor in the loop for its Low Pass characteristics. This inductor usually swamps out the drivers inductance.

All said and done still some intersesting information on that site

Thanks

Take care
