4.0 cu. ft. box suggestions

[Big Dee 10+ year member]

OK I'm building a slot ported 4 cu/ft box for my TC-1000. I have it in a sealed box now and it doesn't have the low end that I thought it would.

So. What is ideal for the thickness and bracing? Double thick walls and bracing, just double thick baffle and bracing? No bracing and 1.5" walls?

Thanks

I'm using .75" MDF btw.

what size sealed box. 4 cube sounds big for 1 12"

I'm using a 1.4 cu ft box right now.

4 cubes is what TC recommends for home audio, and car audio they recommend 3 cubes, but I have the space so I'm just gonna use 4.

Here is the link to their site. Scroll down for box recommendations.

what do you want louder, or just lower?

just use 3/4" or 1" MDF and it'll be ok and i'd stick with the 3^3 recommended size

3 cube tuned to 28-30 hz would give great low end

I want the lower to be louder //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.

The sealed box gets down to 25 hz, but it's pretty weak.

I want to give a boost to the low end, ie. 25-35 hz. and I think a low tuned ported box would work great for that.

With bracing though, correct?

you don't need any bracing for that sub, i had my 15" XXX in 4.0 box with no bracing, just a double front baffle and that sub weighs twice what tc-1000 does and handles about 4 times the power, so you certainly don't need to worry about flex or anything.
