I managed to get some time to do a little prototype of a 8"+1" cab.

Im quite pleased with the results, want to do a few tweaks tho. 
I gave it quick smaarting, to see when its at and as a reference for post tweaking measurements.





Dark red =LF,  Blue=HF, Green= resultant

Very cute!

I assume its the prototype as even little 18mm MDF boxes weigh a bloody ton!

what drivers are we using in this project? And are we gonna try for a passive in them so you wont need to bi-amp?

If it sounds like a gorilla is trying to escape, turn it down.

Indeed used MDF as it the prototype but planning on using 18mm ply for the finished units.

I've used a Fane sovereign 8 225 and a BMS 4524 on a Faital STH100.

Indeed also planning on a passive and maybe a 12" sub to sit under them.

For a little box, you'd probably be ok with 15mm - unless of course you have some 18mm knocking about - with smaller panels and less stresses from the drivers, your back will thank you for it one day :)

I do have enough 18mm lingering about to make 4 of them. It weights 10kg at present but also like the idea of over engineering them bit tho.

Give it a go.
I've done the cab to suite the driver and the passive crossover will also be suited to the cab and driver combo.

Do you have plans I would build these 15 mm I have 2 X 48"X96" BB in my garage. Also will your passive crossover work with my combo as stated above? Can you put up a video on youtube how it sounds your current build rpototype? Be waiting thanks!

After a bit of listening I though the sound was bit looser/slower that I'd like.

To tighten the sound I cut the port down to tune it a little higher and added more dampening.

It lost a few Hz of low end but resulted in quicker/punchier sound to my ears. 
Gave it another quick smaart so see where its at.  

Red=8", Yellow=1", Blue= resultant (Green=previous resultant)

For the passive crossover I'm starting to think of doing a simple crossover and use DSP to optimise the enclosure (in a next style)
