Default Crossover help!

First foray in to proper crossover construction, And, ive discovered there is much more to the black art than meets the eye, In short i'm lost after reading everything applicable online, Ive upgraded factory X overs before so i'm familiar with the mechanics.

The cabs are transmission line three way consisting of these drivers...

2x Hi-Vi RT8II 6ohm 95db recommended crossover frequency @ 1700 hz

2x 6" c'cam rst alloy mid bass drivers ( nicked from monitor audio silvers) 6ohm 90db.

2x yamaha 10" ja25 woofers 8ohm 90db, 50hz to 700..

All pretty well matched as far as efficiency, apart from the yamaha's ohmage, but these can be replaced if its a problem? But i like them because there easilly driven, detailed and produce lots of bass!

Ive enclosed ( I hope) a pdf of the cabinet plans already built.

Ive looked at passive crossover calculators and managed to work a few 1st order and 3rd circuits then found such wonders as bandpass gain, etc must be taken in to account for a proper solution

Was ideally looking for something not too complex after my original thoughts of building quarterwave horns.

Any advice from the constructor buffs hugely appreciated to stear me in the right direction!!!

I'm loathe to use a pair of mission 3 way x overs whispering at me in the corner lol


Oh, room size 25' x 16'
