Easy enclosure for tiny alnico speakers

Anyway, I thank you so much for your very clear and educational explanation (I'm not kidding at all).

.........I'll try a smaller baffle (cm 20x30) with back and sides made out of pegboard as you suggest. In this case I think that I haven't to line perforated parts.

You're welcome!

Yes, you need to damp them even if perforated.

As a general rule, I agree since mass loading the driver to the cab as well as mass loading the cab to whatever surface it sets on improves the driver's acoustical-mechanical efficiency.

I'm not familiar with this particular box, but its constrained layer construction should work well with smaller cabs using higher Qt drivers such as yours apparently are.

Then I filled the box with some fabric. Hmmm...

So I'll definitely go for OBs, maybe 40cm x30.

'Fabric'? This doesn't indicate a suitable damping material and with rare exception, whatever is used shouldn't fill the box when ~'FR' drivers are going to be used for most/all of its BW.

For sure, all drivers sound their best on OBs since both sides of the driver is 'feeling' a near identical acoustic load.

GM:

Fabric? Actually I put a T-shirt in the box as I were disappointed by speakers sound!

Anyway, I see we all agree that OBs are the best option.
Thank you again.

You're welcome!

FWIW, a t-shirt (even a child's) would be way too much for a small driver/box combination.
