Purely speculative at this point, but if I wanted to add a second 4 ohm Barefaced retro 2x10, what amps are out there that could handle it? I know I could run the cabs in series for 8 ohms and ANY amp could handle it, but i need real welly here! Talking 500 watts and above.
My fav amp of all time is the pre-EVO Ashdown ABM so top of my list of possibilities is the ABM900. Second favorite amp is the Orange Terror Bass, which I've owned twice, and it could handle the cabs in series for 500 watts at 8 ohms (there's also the rarer 1000 watt version that would do 900 watts at 8ohms).
Can anyone suggest anything else? Budget would be under £400, new or used - I know Thomann still have some Orange TB500s in stock.

Just to clarify, you'll need an amp that goes down to 2ohm if you want to use two 4ohm cabs.
The vast majority of amps out there will only go to 4ohm through 1x4ohm cab or 2x8ohm cabs.
You run the risk of damaging your amp if you hook up two 4ohm cabs when the amp can only handle 4ohms.
