might have the drivers now, in theory
2x 4" as 'tweeters, and 2x 6" for the passband drivers
wired in paralel/series
crossover ? ......if lucky, maybe nothing, just running loose

new revised crossovers looks almost ordinary
but seem to work for this 'application'

yet another xo revision, just in case someone would be tempted to copy this magnificent speaker
since the woofer now got the long missing inductor, I will look at reversing phase on the mid instead of tweeter
and the mid inductor may be a bit too big now

this one is approved, and finished
works great now

spent a few hard days trying to figure out what went wrong when I implemented a trafo inductor on the woofer
reversing phase on the wrong driver completely screwed the whole speaker
and it screwed up my playing too

makes one wonder how many poorly performing bass systems there are out there

but mine works now, and makes me glad playing again

Just curious, why do you still use passive crossovers in a Biamped system?
Sort of defeats the whole idea of biamping.

me too

but was expecting to go active ... later

just wanted to know if it would be simpler when only for bass guitar
and I almost tend to say, it appears even more 'picky' than for music/hifi
there is no doubt that it affects your playing quite significantly
imagination alone wont do it

I choose not to use artificial effects
but it might have been much easier

a simple PLLXO line level xo should work nicely for this speaker
unfortunately my present solid state power amp have much too low input impedance
or else I would have tried it instead

but when I build the hi-Z pre out buffer I guess it will be a natural mate
and I also had this weird idea to mate the xo with baxandall controls
