Impedance and Sound Quality

4.62 ohm sounds a lot better than 3.48ohm

4.01ohm is the best compromise between SQ and SPL.

True and tried!//content.invisioncic.com/y282845/emoticons/blush.gif.99bc659ee2012b7d826165e26fb5eebe.gif

Well, and ofcourse that means all speakers sound absolutely horrid at resonance..........

confusing noobs again are we? //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

But seriously don’t worry about it... Just make sure your amp is happy //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Also remember that series resistance will alter things more with a lower impd load... so if you are using those shitty 20-22awg stock wires that your car was wired with from the factory... this is an issue... otherwise don't worry about anything whatsoever... so long as your amp is happy (not driving too low an impd load) //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

in the amplifier.....which if it's within it's linear range will still likely be an inaudible amount //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I agree. I was more or less speaking in general. I said inaudible on my first post.

Thanks for the feedback guys. So I can run a pair of 4 ohm speakers out of two channels of my amp, and a pair of 8 ohm speakers out of the other two, and there's nothing I have to set up with the amp? I'm assuming it would just be running the 4 ohm pair at a higher current than the 8 ohm, and therefore working the amp section that's powering the 4 ohms a little harder than the other?

And on the Adire Extremis speakers - if I were to stick them in the back panels as mid drivers and run all the treble through the MB Quarts in the front would I be wanting more mid-high and treble? With a sub installed would rear mids even buy me any additional punch for the money?
