1000 Ohm loudspeaker

Hi,
I've got some strange idea ...of >1000 Ohm loudspeaker. It can be done. It was done before (at least 500-600 Ohm). Is it worth trying?
To clarify my point - a quote from "Tube CAD Journal":
"The big problem tube OTL amplifier face is having to deliver the high current needed to drive the low impedance loudspeaker. One watt into 8 ohms requires a peak current delivery of 500 mA, as (0.5˛ x 8) / 2 = 1. Which means that a total of four EL509s is needed to meat the 250 mA idle current demand of the push-pull amplifier. If the load impedance were 285 ohms, then the same 500 mA peak current swing would yield 35 Class-A watts. What the world needs is a great 100 ohm loudspeaker!"
"The world needs a great 100 ohm loudspeaker" - well, what about great 1000 Ohm loudspeaker?
It can be done.
Any comments?
