bass speaker help

[tinitus]

I was thinking of the small type of effect devices
some doesnt cost much, if one doesnt know how to

one problem is to figure out which one is needed
and I still havent
compressors, and whatever else is needed

which is why I have decided to buy a plug and play head amp
one that works properly, but still affordable
I dont understand the electronics involved here
instead I will put my DIY efforts into the guitar building

this instrument amplification/speaker setup is far from so straight forward as thought it would be
seems like nothing much of my hifi expriences is any good
different world, it seems
well, live and learn, they say

A compressor is certainly needed for a clean bass tone. My guitar amp knows that. Hooked it up to a bass guitar, cone excursion was very peaky, but went to maybe 8mm p/p. With just the note ringing, it was down to more like 3 or 4mm (this was with a 10" driver open backed, on maybe a couple of watts). Getting rid of that initial peak is important for your speakers and your amplifier, as it will eat up mechanical and electrical headroom.
I think I'd clone something like this Marshall.
That way, you have enough power to drive external speakers if needed, and you can try tweaking different things and learning what everything does, without having a huge, complicated rig to mess with.

finally decided on a design

I have the woofer, a 15" with highish 0.55 Qts
and relatively big and cheap horn, with a cheap CD

if it sounds OK I might build another one, so that it could be used for other purposes

Wheels? Are you in a sixties cover band? Will it be covered in gold Fablon?

yeah, wheels are cool ...nah, makes the drawing look more real

but I have some funny little wheels you barely notice

[tinitus]

change of plans, again

[tinitus]

shoot, more ideas

now Im getting really indecisive

any opinions that could help me choose one ?

well, version A would be a really easy build me like it

What are the triangular lines either side of the bass driver?

[tinitus]

oh, ok, ofcourse thats not very clear

those indicate inner baffles

and, the box is open at both sides, in all drawings

BVR, midbass horn, folded dipole, open bass bin
I have no idea what to call it

Hmm, I'd guess a rear loaded horn. A compression chamber in the centre, loaded by two slots at the top and bottom that drive short mid range horns. Might well be quite crisp with all that upper mid, I'd knock up a test box if I were you.
