My Box Build. Do I Know What I'm Doing?

[Posjr 10+ year member]

I'm making a sub box for the apt. My goal was to get as low as i can with min. space. Right now i'm at 1cube box tuned to 24hz. This is based of a infinity ref W860. Why in 8in? I got a grumpy old lady up stairs.....

Here is a pix of the tune i did with winisd. Also its a 12.5x2in port, 25sq inch port, and I think i'm at 110in length of port.

My concern now is am i wasting my time because its an 8in?

After tossing and turning last night i feel i should of went with a 10in...... You guys know any 10in subs that can be in a 1cube box? Rms under 500@4ohms Price under $200.....

I'm not trying to be loud just want to feel some 25hz. I'm not sure if this 8in will put out enough!

Also i have gone through a list of subs at 10in and cant get lower than 1.8cubes.

I wouldn't be afraid to use an eight.... Btw, your enclosure looks nice. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
