Wondering if anyone know who would manufacter a 250 watt amp at 2 ohms.

I believe most of the DCA line of QSC amps will go down to 2 Ohms. 1222, 1622 will both work at low impedance unless you run them in bridge mode. Also 1644 four channel amp.

Another ex Ashly user I presume?

If you need at least 250 watts and don't mind more, the entire QSC DCA 2-channel line does it and more, starting at 600w/ch and going up to 1,700w/ch.

The DCA 1644 is NOT recommended for 2 ohms but the DCA 1824 is, at 450 w/ch. Both are 4-channel amps.

They have a new "CMX" Series which starts off at 430w/ch: (RMX Series also starts at 430w/ch)

If you don't mind the weight, old Series One chassis profile, and Hecho in China, the ISA Series starts at 430w/ch:

And finally, the old MX/MXa Series does 2 ohms, starting at 350w/ch

You have lots of choices just in QSC's line. Other manufacturers also have amps capable of 2-ohm operation.
