The dual mids don't know if they should squawk or woof. It's sort of a similar limitation with the M3 and M50 but it seems more natural for a woofer to try to squawk than a mid to try to woof. I find the M3s and M50s are soothing while the M22s are irritating even with a sub. I'm hoping the M2s are better.
