If it ain't broke...

If you wanted a compact version, how about a coaxial driver?
Or maybe the Eminence Beta 12LT that people seem to like? (no XO needed for that one)

Can you measure the voltages going to the tweeter as you play the full range of your "effects".

It may be that the bass guitar has almost no tweeter content.

Or switch off the bass and mid speakers and listen to the tweeter alone (don't adjust the volume). That should show what the treble content is and why you "hear" that effect.

not much I guess
even so, tweeter phase is still affecting other drivers in the system

but you know that strange and worse things might happen when 'something' rolls off rapidly
tells us about it, please

btw, I have tried a big light coned woofer
and just hated its squeaky midrange
I suspect caused by a too big, stiff and light cone
well, muffled aint too good either
its not so easy at all

hey, I love my new speaker, no doubt about it
and my bass is vey cheap, and a better one ought to give better sound
right now I fancy a 5-string Steinberger

ahh, found I had a bigger inductor, amd changed the paralel curcuit on tweeter

WOW, the whole speaker sings nicely now

well, it is a big surprice it actually works that way, and not much differnet from a hifi speaker
proves my worst fears
will post xo schematic later

crossover, but still preliminary
not looking perfect at all, but it works
because I have made multiple changes and adjustments, and all resulting in improved precison and playability, I would say it is getting quite good now

but I need to buy more components to any further
still surprising how much a tweeter xo affects the playing

shoot, paralel inductors were shown/drawn with wrong connection

corrected, and a bit different

btw, I shot a few new and better pics of my project
I think you can take it just once more
Im beginning to enjoy it, and it more and more every day
got nice tune, and rocks, its good

crossover change/update

less noise/hiss
and now the 'onboard' tone control pot on bass guitar actually works
makes the sound more airy, instead of just 'nasty'

and even better tune, improving playability further

compressor pedal arrives in a few days
will be interesting what that will do

I compressor will help if your playing seems to be inconsistent.
I once recorded a bass player where his playing was right on but the levels of him hitting the strings were all over the place.
I had to ride that channel a lot during the mix down so adding a compressor fixed most of it.
This is the very reason why some bass amps have compressors built in to their preamp.

Nice Job on that Speaker, tinitus !!!

very nice of you, thanks

I have now tested it with hifi music
better than expected, given the poor xo
but not much to write about either

but the tweeter is the really big surprice
and indicates that my tweeter xo might work
sounds very 'hifi', and clearly points the direction for my future home hifi

the next positive surprice was woofer lower midrange
but also clear that the early bass rolloff result in wimpy 'cardboardbox' bass
only way I can describe the effect

even so, for bass guitar it still produce very good and low bass
at times maybe even too much
just one of those weird things I guess

as for the rest...well
have to work on upper midrange(bigger inductor)
