My buddy and I are working on a sealed 15" Dayton Ultimax 4.0cu ft build. I received the the advice for that about a year ago here. He is a carpenter and I wanted to do a piano gloss black box. However, he has been extremely busy and we can't work together probably for a few months. We have the exterior cut and glued but I am halted at bracing.

In the meantime, I am dying with my current crappy old 10" 100W sub. I need to buy one of the pre-cut boxes and build a sub at my own home. I need advice on what direction to go. The 15" Dayton will eventually make its way here.

The current room is a basement thats 14X19x8' ceiling. However, I am more than likely to move out soon into an apartment where my sub(s) will not be turned up. Regardless I'd like good sound quality, because I can always sell them to a friend. Size of box is a concern because an apartment will not have a ton of space. Also, most of my friends are married or practically married and wives scowl at the big bass boxes.

I'm thinking 12' ported w/ some sort of iNuke amp. I'm open to suggestions if that is not a great idea. Thanks in advance!

Box size is is one of the variables in what is called Hoffman's Iron Law.
The other variables are: Desired Low Frequency Extension ) and how loud does it have to be.

So a large box is out: then you have to decide how to play the other 2 variables.
A small box and LFE means that it requires more power to achieve a target SPL vs a Larger box OR not going for LFE.

You could pick up a flat pack box for the Dayton 15" until you and your buddy finish the custom box. The 3 cu ft box is only $90.

Otherwise maybe an Anarchy Tapped Horn would work?

There are a number of boxes at diysoundgroup.com that will fit your needs.

the 4.0 cubic ported box seems nicely sized.

What do you guys think about that? Should I just select one of the two Dayton's recommended?

Amp suggestions?
