[QUOTE="Buck, post: 8767461, member: 591582"] Yeah man, like a lot of microwave ovens are 1000-1500 watts. Think about how much heat those can make. I totally get what you mean when there's no replacement for mass. That's a really good post you did there man, I like that. I know with some subs without pole vents, like my older Fi BL's (like 2008 versions), that some people complained about a popping sound or potentially a weird sound on high xmax where there was a bunch of pressure like above the motor pole / behind the dustcap. I never noticed that, personally. I know I popped one of my DC dustcaps off, and they did have a pole vent lol. This is just another "pick your brain" question: what do you think about the heat dissipation difference between shorter 8 layer 3" coils vs longer 4 layer 3" coils? Do you think the longer 4 layer coils have better heat dissipation? IIRC, that might be one of the design changes between the Zv5 and Zv6 is the Zv6 may be going back to a shorter 8 layer 3" VC vs the Zv5's 4 layer longer VC, but don't quote me on that. That's just a "maybe iirc" comment. I might not be remembering properly. Neo's do seem to have inherently better cooling properties, there's less motor mass around the coil and often plenty of raw, open air for the coil to interact with.
