2123h..j why care?

[Windsor2k1]

Folks--I've been working on a custom speaker setup and I want to use 2 10-inch JBL drivers.. 2123h/j, or 2012h... on each side. If i used 2 speakers on each side obviously that would cut the impedence in half. If i used h's (8 ohm)... and ran them in series then i would have a 4 ohm load. If i used j's and ran 'em in series it would be an overall 8 ohm load... Why care? Other than it is easier to power a 4 ohm load... Why should i care? I have heard that running the 16 ohm drivers in series (so the overall impedence is 8 ohm) is best. Just curious why that is... Thoughts, theories?

Series adds 2x8 is 16ohms, 2x16 is 32ohms. Parrallel divides in half. 2X8 is 4ohms and 2x16 is 8ohms. If you run in parrallel you need to look at an impeadance curve to see what the minimum is and where. Most home amps and recievers don't like loads under 4 ohms.

Pairs of 16-Ohm drivers are often used in parallel to match the typical 8 Ohm impedance of passive crossovers. If you're doing active, it shouldn't matter, as long as you can successfully drive the 4-Ohm load....

Thanks guys... parallel is what I was referring to... thanks for the correction.
