So if running two 8 ohms speakers then you get 2 x 225 watts (450 watts). It gets a bit more complicated after that if running 2 x 8 ohm speakers as a 4 ohm config or 2 x 4 ohms speakers.
Now do I get the LH1000 with either 1 x 8 ohms speaker (750 watts) or 1 x 4 ohms speaker (1100 watts) or the £50 cheaper LH500 with 1 x 4 ohms speaker (500 watts). Not sure if running just 1 speaker with that much output is the right thing to do.[/quote]
Bridge mode - 1 x 8 ohm or 1 x 4 ohm or 2 x 8 ohm daisy-chained
Dual parallel - 2 x 8 ohm or 2 x 4 ohm, each plugged in to the amp seperately
I'm sure I read something about not using just one side in dual parallel mode, but I can't find it now!

I have used the 1000 bridged into both the Barefaced Big One [6 ohm] and Compact [8 ohm] - the Big One was obscenely loud and I struggled to get the volume above 5 or 6 even in a fair sized arts centre 'cos as Alex has said, the LH heads really take off at about 6. I gigged at 1 and a bit. The Compact was quieter but still very loud and clear and just about made 6 in a small rehearsal studio. I rehearsed at 3. The sound was totally clear and the cabs had much more to give. I could probably got away with the 500, but hey - I want it to be the last amp I buy for a good while.

I believe I have one on order
