View Full Version : Possible stupid question about 2226 G/H/J

I was assuming they were compatible, meaning that you could drop a C4R, C8R or C16R2226 in any basket since the motor/frame was basically the same, a 2226, period.

(Thanks Earl K :))
I found that the flux is different for the 4ohms version so it makes me wonder :blink:
The magnet gaps would be different?

P.S., yes I searched before asking and I didn't find a definite answer. ;)

Questions are never stupid, answers can. :dont-know

Gaps the same.

Gaps are the same, BL/Sensitivity/Le and other specs will change, however. They're largely a "box drop in", meaning similar/equivalent acoustic performance, but different crossover requirements.

That's what I tought, but why would the 2226G have 1.05T flux instead of 1 like the H and the J :blink:

That value has nothing to do with voice coil or cone or mechanics.

Hmm.. my guess was the G model came later and someone retested/remeasured,
so that the new T/S table row got entered as measured...
and there really is no difference. Emphasis on [also just a guess]. :)

Agree...this is most likely the case...they wouldnt make different motors

Right. Same motor. Just upping the flux isn't that simple- they operate the motors with the most flux density they can get for a given assembly. Need less flux, shrink the magnet.

Thanks for the answers!
