JBL crossover / impedance interaction

[Tom Loizeaux]

In looking at the JBL 3110 and 3120 passive crossovers, I have noticed that the 3110 (800 hz) is listed as being set up for a 12-16 ohm woofer while the 3120 (1200 Hz) is listed as being for 8-12 ohm woofers. Those numbers vary a little from one JBL publication to the next, but it seems to indicate that the 3110 was designed for 16 ohm woofers and the 3120 was designed for 8 ohm woofers.

My question is: How will the crossover curve be affecteed if you were put an 8 ohm woofer (and the correct 16 ohm HF) on the 3110 crossover?
...I suspect that the woofer might extend a little higher, passing a little more high frequency and I suppose creating a slight rise in the overall response around 1K. ?

Any explanation on all this and what I will get using this 3110 w/ an 8 ohm woofer?

Thanks,

Tom
