Doing math is useless. But I can "try" to take the numbers right off your own measurement thread,
although you never tested the sustained figures for stereo 4-ohm vs bridge 4-ohm on the same model of fp14k (or if you did, you never posted it. i.e. for the 2-ohm stable one obviously.)
You only posted the burst figures, from the older model vs the newer model.
So that's all we have to go off of I guess...
Your posts aren't clear if that's 6kW or 3kW per channel. So again we have to make additional assumptions.
If it's 2x 3kW burst, then 13.1kW burst is more than double per cone.
If it's 2x 6kW burst, then 13.1kW burst is more than double per cone, still...
I'd imagine sustained won't be too much different, as far as making double power at least.
You never mentioned what the sustained power of the 2-ohm stable version was/is.
But based off the old one we could assume it's likely to be 2x [email protected]
and 1x [email protected]
based on your comments about sustained power of the old version in stereo mode.
You'd probably know more about the precise-figures, after all, you're the one who tested like 4 different variants of the fp14k.
Had you posted the burst and sustained powers for all variants, we wouldn't have to speculate or guess what the sustained power of the 2-ohm stable version is in stereo 4ohm vs 4ohm bridged. So: do tell...
Until then, I will continue to assume bridge-mode is "nearly double (or better...)" than stereo mode.
and additionally that: the bridge-mode of a 14k will "easily out-do" a single mono channel of a 10k, 20k or 14k LOL
I can't see how double the transistors into half the ohms won't produce WAY more power (for the models rated for running in that mode, I might add...)
