Hi new to DIY and building speakers all together. My cabinetry skills far outshine my knowledge of building speakers. I am building a sub box for a home theater. I am however using a boston acoustics g1 10" car sub. Speaker choice opinions aside I have read that car audio boxes are spec'ed out differently because they go in your car. I built the recommended .5ft3 box and its ok, but just ok. I was looking to build band pass box or a box with passive radiation. I'm told not to do the rads though because of the Q rating. I'd love to go this way with a big radiator but if its unwise I won't. If not I am going to build a ported box. I'd like to build only one more box as this time it's going to get a veneer and finish. I'm attaching a link to. The spec page for the speaker, it is the g1104 model.

If anyone can help me find a good box size it would be great. I tried a calculator but it seemed like I did something wrong

Yep that is a design for a car and relies in cabin gain to get any low end.
For home use a large vented box (3cft) witha long port 5"x19" would work better.
Here is a simulation vs. the closed box.

Bjorno like I said not too keen on the technical side of building a box. Although I'm only on my phone. Ill have to look that over later
So if I'm going to build a box with a port that size it would be easier for me to do a slot. Given a width of 9.75 inches what would the height and width be on that? It would be below the regular box so not to ruin the volume
Inductor what size sealed box?also I googled the quarter wave and I like it, but how do you design that? How many baffles, size ect?
VB = 60.0 L for a QTC = 0.707.
I'm not an expert in quarter wave but bjorno is always posting a project for one.

An externally hosted image should be here but it was not working when we last tested it.
wow... lol so no im not going to build that. i do have two rather large pieces of walnut. id like to build a big box out of them. two sides and then black vynil wrap around the center... any of this construction is not an issue for me.
I'm almost sure bjorno post #3 is one of them. It's just too confusing for me. 🙂
At this moment (for my small math mind) I would just ask you for the thickness of the wood you're using (18mm, other?)
ps. At this moment OP is looking for a TLQW design for his speakers.
