Speaker Efficiency in IR's?

[AndyOrr]

BITD, I tended to swap out my speakers pretty often (largely based on my attraction to nothing more than that company's ad copy, I suppose). One of the first things I always noticed after the swap was how much the speaker selection affected the amplifier's volume and the level at which I could achieve some break-up. I haven't noticed this same phenomena when selecting the various stock cab blocks in the Axe.

Is speaker efficiency taken in to consideration when the IR's are recorded?

Is there any difference in the aftermarket IR's?

Are there any stock cabs that break up earlier or stay cleaner longer?

No. With real speakers, you can have differences of up to 6db in sensitivity, which is the same as going from 25w to a 100w amp. IR is just data of the speaker's tone, not volume, and they are normalized to the same volume. And there's no distortion changes in the IR if you change levels.

Thanks Aziz. I suspected as much but have never used the aftermarket IR's.

There are parameters in the CAB block that would add non-linear things but the SPKR page of the AMP block is where this type of thing is modeled.

If you want to play with break up on speakers add motor drive in the cab block .

I wish the motor drive would get an overhaul. It just make the speaker sound like it's blown!
