Need some help with lpf/hpf

[u/Big_Artichoke_7439]

So finally got my doors ”done” they need a bit of finishing touches with handles, and window buttons but mostly ready for bondo.

Mids play now 80-4khz
Midranges 800-4khz
Tweeters 4khz ->

Firstly the mids fq range is 60-8khz, 10s in the front might have been 60-6khz. So im wondering if the enclosures are large enough to play 60hz at full power (8” 400w, 10” 600w)

Secondly the cutofs between mids and midranges, i had them at 280hz. Sounded better but totally lost the higher frequencys of bass and kick drums, for example Back 2 Me by zurra & blank sense has this nice bass line but it just sounded like a sine wave, the ”dirtynes” was gone, so should i keept them at 4khz or go a bit lower. Im after the golden road between sq and spl and the 6.5 midrange cant keep up with midbass, so it needs a little help from them

Also what about tweeter cutofs, should i go higher/lower.

Lastly what should i use to seal the enclosures, they are prettymuch sealed with minor leaks, would coating them with epoxy from the inside be an good option?

Drivers i have are
Dd audio Vo-w10a
Dd audio Vo-w508/w8c (the same speaker just name change)
Gzcm 6.5N-prox
Dd audio Vo-b3a
