To be "frank"..
Ok, I found this article and the value of a 6.5 and a 6.2 ohm speaker would be called 8 ohm's nominal e impedance,If this is not corrct someone correct me Please.

I saw that dayton woofer and did a side by side with the peerless,I tham going to get the peerless.
In my applications, the rating although mathematically is lower than 8ohms, at the crossover, due to inductive and capacitive "reactance", the load is seen at the amp as near/8ohms.
Not sure why this is.... but in all my crossover designs, it did not cause operational issues. Now if the a speaker without a crossover is 4ohms.., and you have an amp rated at the terminals as 8 only, you will have issues.
I have found the compensation for impedance delivered by most crossovers to be impressive.
Again, this is a discussion in other forums I have found most interesting because it involves sometimes three to five variables.. RE: Amplifier, speaker, crossover, operational demands, and then the original spec for each element.
I can only speak of the last two crossovers I used and those speakers connected. In both cases, the speakers were of various nominal ratings, yet the overall performance expectations were met:yes:.
To be "frank", I am more concerned with individual speaker survivability, this in terms of protection. There are various ways of doing this and I chose to use the Parts Express, "in-line" protection for midrange and tweeters.
However... you are doing yourself a great service by reading the specs thoroughly.. as I have found, no two speakers are the same.. nor suitable for "one-size-fits-all".
