Ok, theres a few problems here.
1) 1/2" MDF. Thats not acceptable to use in a sub box- period. 3/4" MDF or better- or go home!
2) MDF Caulk?

Whats air tightness?
Thats box is small, just way to small. You really cant tell what the build quality is, it has carpet on it! Whats the QTC on it? What all subs will fit in it? Just because its 6" to the back wall, you CANT shove a sub in there with a 6" mounting depth!
If you guys want boxes hit me up.

I build my boxes to your equipment (subs/amps) and tailored to the type of music you listen to adn to your expectations. From SPL to SQ, I can do it.
I will be stepping up my equipment (panel saw) and the lead time will be cut down.
I back my enclosures with over 10 years experience and literally 100's of boxes Ive built over the years.
Furthermore- in a few weeks I will be adding pictures of MY Alero install. Hell, check the FS section for my 8" 6th order Bandpass box
