Default removable bottom to mount and access crossover?

How to most folks address crossover location and accessibility? I am building some 3-way monitors with curved sides similar in concept to the curved cabinets from parts express and the only place with enough area to mount the X/O is the bottom of the speaker.

To do this would require that the bottom be removable...How is this going to impact cabinet resonance since I can't brace it if it the X/O takes up the whole floor?

THX

Since it is DIY I always advise to put it externally . Different from buying a 'black box'.
BTW I was reading today ( guess what sort of readings .... )
that the box servers for two purposes : protecting the speaker and containing the crossover

There's no law that says that a crossover all has to be in one lump. You could split the individual sections to form smaller boards to ease mounting. Or, as Pico suggests, mount it externally for easier tweaking. You know you will.

Do most folks use a removable access pannel or go in through the woofer cutout? I will have a 6" cutout but with 3" of height on the crossover I don't think (it) they can get through.

Doesn't seem much point in only going with a 6.5" driver for a three way. I'd at least make it an 8", and a 10" would be even better.

mmmh
Some say that a 6.5" at home is a gigantic size . The maximum allowable.

The fact is that the loudspeaker must be able to put the listener in
the situation to make him(her/it the cat/dog) live again the recording,
and it's a matter of wavelenghts and reverberation ( of the original environment superimposed to the listener's one ) and to make him
to discern ,at every instant ...something like a decoding technique , what is playing and which instrument . That is valid mostly with classical music
where there is an established reality to compare with, it is not valid with electronic music or heavy processed one , so one can give attribution to
sounds and where they come from .
The size of the bass unit is referred mostly of how it is related to many
other magnitudes, such as the box size, shape, position in room and necessity
to play at the desired volume what the composition must express,nothing more nothing less, so there's no 'bomb the bass' or something else effect.
The size of normal rooms for normal audience ...2 or three people max
and positioning of the listener...which is presumably 1.5/2.5 m from the speakers , and the relation to the other (2 ways) driver units suggest that for a correct attribution to each instrument the size of the bass unit must not exceed 6.5" -

Nope, don't agree with that at all.

Sorry for the Off-Topic Koosh.
