Speaker Impedance: Resistance and Phase Question

Thanks very much Larryi and Al. When I stated speaker phase shift I meant to say phase angle. Given the relative 'lameness' of my question, I was provided exceptional feedback. It came as no surprise given the authors.

I wish to provide a little feedback on myself and my equipment given the the kind responses I have garnished. I have been involved in this hobby since I was 20, some 44 years ago. In that time I have developed only 3 systems, all on the budget end. My current system: Esoteric MG10s, Bel 1001MK5, Jolida Fusion 3000, Arcan DV137, PS Digital Link III w/Hiface USBtoSPDIF, Sonographe turntable (bought in 1983), Bluepoint N0. 2, Lounge phonostage, Kimber and Audioquest cables. Looking to replace the DAC and USB converter as evident from some of my other posts.

I only became involved in this forum this year and have enjoyed it immensely.
Thanks to all.

I should add to my previous post that I first became aware of the importance of speaker reactance via John Atkinson's writings and that aspect of Stereophile,s speaker evaluation I find most informative. I have long known that reactance =resistance+inductance+capacitance however am gaining a far better understanding. Would it be fair to say that capacitance becomes a most critical issue over inductance or resistance in regards to speaker and speaker cable interaction with cables having adequate isolation between the = and - strands and of an adequate gauge?
