Both the 8 ohms and the 4 ohms terminals sound good, the high end is lowered a bit in the 4 ohm, which brings out the bass more, but the high end does sound better with 8 ohms. Which do you all use?

I just checked the speaker impedance and I was getting something around 4.6 off the back of the speaker terminals (nothing attached). I thought the speakers were supposed to be 8 ohms, but it looks like I could hook them up to the 4 ohm terminal. Any thoughts? I found this thread from 2003: https://community.klipsch.com/index.php?/topic/27349-nominal-cornwall-impedance/

Wow, thanks GaryRC!

Here is a pic of the crossover if anyone is interested.

Thanks for the position ideas. Right now the Christmas tree is in the corner of the room and we have the entire stereo set up shifted over to make room for the tree. After Christmas is done, I will do some placement experiments. With respects to the crossover: In general, should I replace the caps on the crossover? I have spoken to two people that say no need to the those are fairly robust on the Cornwall, but I've read tons of places that 30 years is just too long for capacitors. I know there is one leaf cap, which is probably fine, another one in a can that looks like an AC fan capacitor, and finally a large 70uF one for the woofer that looks like a half stick of dynamite.

Thanks for the input, I will try some room placement options. I do have wood floors and I have a rug in the middle, the speakers are directly on the wood floor. When you speak of aiming, I assume in general you face them inward and not outward correct? Let me follow up with a question too: I typically have always kept my bass and treble adjustments at a flat 12:00, now with the Klipsch, I found that putting them around 3:00 to 4:00 really give me the bass I want. (I mentioned in my original post that those adjustments were not helping, I guess I was just not going extreme enough). I always thought that keeping your controls flat was the way to go and bumping any of them was somewhat frowned upon... any thoughts?

Hello, I just purchased a pair of Cornwalls with the B3 crossover, 1983 I believe. I bought them very spur of the moment from a shop as my wife was with me and gave me the ok (I am still in shock she said yes to be honest). Anyway, I hooked them up to my vintage mac gear (tube preamp) that I recently recaped and they sound 1000x better than my previous pair of speakers. The high end could bring tears to your eyes, but I am having some problems with the bass sound. Its there and its clean, but it just doesn't seem to be in balance with the levels of the high end. I want to keep turning up the sound to bring the bass out, but obviously that turns up everything (the bass preamp adjustment also doesn't fit my tastes). Maybe I am just not used to such high end speakers, but in a way my chest kind of feels empty when listing because i want some more low end to balance with the high end. So I was wondering if this was typical of the Cornwalls, if a recap would help, if I should maybe do a remod and add some resistance, or if I am just an amateur and need to appreciate real speakers.... Thanks for the input!
