Flatwound voicecoil advantages

[herculeshero 10+ year member]

So I've contacted PSI for a recone on my SA-10. When I put that I didn't need any extra power handling at 1000 watts(because I've heard of so many taking that daily) they responded in their quote that they would recommend upgraded voice coils for that power. Now I don't disagree with this, mainly because I know they've been doing this stuff much longer than I've even thought about it. But it did lead me to want to hear some discussion on it as they recommended 8 layer flatwound voice coil and linear roil spiders.

What advantage does the flat coil have? And do the linear spiders in theory help flat out the response curve? Sorry if these are easy questions, I just like knowing the results if I choose to do the recone. Honestly it sounds like my sub would be even better than it was before as I see a lot of these options on some more costly subs. Thanks in advance!

Flatwound coils basically allow the coils to sit right next to each other since they are flat. Reguar wire on most subs is round, so only the middle really touches so you can pack more wire into the same VC height using flatwound wire. This gives you more motor force and more powerhandling.
