My new-to-me 820s

I'm gonna do Iron cores on the LF side and Air core on the HF side. I didn't like how the air cores sounded on the LF side. And not real happy with how Iron cores sound on my HF side. I have iron core on both now but the air cores for the HF side will be here Tuesday.

That is a useful observation. I guess I would have expected the opposite - since the high power, where saturation might be an issue, would be on the bass side.

Which air cores did you go with?
