It is not easy!
A week working right, that measures be exact.
But it is very rewarding.

I just wanted an idea of the position of foams.

Good work Nelnar!

I never use foams to lime the walls in a TL but instead different felt= dense types up to an inch of thickness. The given material for damping the enclosure should be of ordinary polyester type that can be adjusted to different densities.

It is very gratifying a compliment coming from you.
Thank you!
But, you are responsible for my success.
Then take half of the TL, what do you think of fiberglass filler?

Fiberglass will work too. but when used for bulk volume stuffing, leave at least 25-50 % of this volume without, i.e. e.g.:Use 2inch battens in parallel with a 1-2 inch free air passage until paralleled with more battens.The arrangement should look like an soundproofed ventilation air duct.

PS: I my previous post I wrote: ' never use foams to lime the walls'. Should be: I never use foams glued to the walls.

Default crossover 1 way

Does anyone have a schematic for a crossover of a subwoofer 1way, this up considering the potency 300/400w rms 3ohms.
