I have many Klaus Schulze albums, one of them made the loudspeaker impedance drop, when I had a 4 ohms speaker the impedance fell to a level my famous pro-audio power amp 4 ohms capable burn a diode, I afraid of 4 ohms speakers.

Tekton could connect these 4 ohms woofers in serial for a more easy 8 ohms load.

Don't redesign the wheel FRM, I'm sure the builder knows what they're doing. Series wiring (assuming they aren't already) changes other parameters. 

Even though they don't publish an impedance curve that I see, the builder said the 4ohm version doesn't dip below 4ohms.

They simply made available a different version for folks who have tube amplifiers that don't have a 4ohm tap or have high fixed output impedance typical of SET. Apparently, that version is a slight compromise in performance.  No need for the OP to compromise. The builder recommends they buy the 4ohm version.  :D
