Newbie Question: Cheapest route to 2 ohm stable

[Ignite]

I'm wondering about how I could drive a 2 ohm impedance without burning out an amp. It seems to me nearly all 2 ohm stable amplifiers are ridiculously expensive, so I am wondering if there is other means. Would it be possible to use a 2:1 transformer for this and use a 4 ohm stable amp? I'm looking for very high wattage (~500W into 2 ohms) and an amp with house AC power supply.

A friend of mine drives a very difficult 2 ohm load with his Leach.The rails are 63V.His has three pair of MJ15011/12 vs the stock one having two pair of MJ15004/04.Today I would use MJ21193/94 for outputs and the MJE15030/31 for drivers.I can provide heatsink tunnels drilled for a stereo amp if you need them.I also have power supply parts.

If you can find copies of Elektor magazine for October and December 1992 they contain a project "Output amplifier for ribbon loudspeakers" .

If my memory serves it was designed to drive 2 ohm ribbons.

2 ohms stability

if you use a transformer, you wouldn't gain any more power, mearly loose it. just get another set of speakers, wire them so it presents a 4 ohms load

You didn't say how hard you want to drive this
load, or whether it is truly 2 ohms or simply
dips to 2 ohms.
