I have some questions regarding output powers and cab impedances as I'm a little baffled! I tried a Warwick Profet 3.3 through a WCA411 pro at 4 ohms and it sounded great! I need a little more power but not a great deal more so I'm probably gonna get a Profet 5.1 whilest there still some new ones left and £85 cheaper than a 5.2. In terms of cabs though I'm not sure whether to get a 411 or a 410. I know the 411 has a total of 600 Watts power whereas the 410 has 300 so my 1st question is.. Does it actually make the amp sound louder? Personally I thought the only reason for getting a 600 Watt cab is to match the output of a say 1 KW head running at 8 Ohms. Is this theory correct though cos there seem to be a bunch of people using 411 cabs into 500 Watt heads at 8 Ohms so they're only using 50% of the cabs power handling. Supposing there is a difference in sound between a 410 and a 411 cab hooked up to a Profet 5.1 at 8 Ohms.. What would that difference be? Last one.. If a Profet 5.1 puts out 500 Watts at 4 Ohms then does anyone know what it uses at 8 Ohms? Thankyou!
