That has never happened at InDIYana, not even EQ’s incorrectly l-padded design. The Crowns we’ve been using since 2011 have never complained or shut down.
We have had venue panel circuit breakers trip for no reason at all, and also trip because of more than moderate output level attempts.
Use a large capacitor between 600uF and 1000uf, and a lowpass of significant inductance and/or higher DCR, and you should be of benign enough load. Solen Litz have inherently higher DCR if that helps.
That’s what I’m going to try with my 3way with the E150HE-44.
Soon as I find the right woofers, sir.
I have a bunch of amps that have no trouble with 2 ohms or whatever. When designing speakers, I do tend to avoid anything much below 4 ohms - mostly because I don’t want to be responsible for blowing up someone else’s receiver/amp. I’ve also spent a fair amount of time lurking on Pro Audio forums and tended to side with the “respect your equipment” camp, that avoided 2 ohm loads.
My Hafler DH500 ran a pair of 2 ohm ribbons for many years. I run my computer speakers with a vintage Proton receiver that’s rated for 2 ohms.
I had a design at 3ohm and ran it on some really cheap amps (<$20) and they all ran fine.
Probably sticking my foot in my mouth:
I figure it would have a good portion to do with current capacity. Though I wonder if there are also limitations on the damping that could push the circuit out of it’s stability range with too low impedance?
