okay thanks for the response, I think my best bet is building a lighter box for my 18 and sell the 12 as it is. Ive tried selling the 18 before and everyone seemed scared of it

Good luck finding 1" mdf at most stores. Really informative, thank you. If you read what I said, you'd realize that I've used past-tense and that the box has already been built. What do you suggest I do with the woofer then? put it in bandpass?

Well it sounds great and I couldn't ask more for SQ. I was very surprised at how loud it can play the low notes in the sealed box. I was just trying to achieve some weight reduction from a ported 18" Q to a sealed 12" but the loss of dBs isnt worth it. The 18 was flexing my sound deadened panels and making me say holy shit everytime I listened to it, the 12 in a sealed just feels like a waste of the system. I will forever love ported enclosures and laugh at sealed.... gunna make a ported box for the 12 and see how it goes. I built the sealed enclosure to the cut sheet dimensions plus 3/4" all around (used 1" mdf and added 1" to the dimensions). sealed it all up with silicone ect, there are no leaks

Okay, I've built a lot of ported boxes. Making this wayyy too complicated I guess lol

What about 45 degree pieces in the corners?

Oh thanks for the heads up, I havent looked at those before. I'll adjust those dimensions a bit and see how it goes!

I just received my fully loaded 12" Q with high qts option. Was wondering if anyone has been trying or testing sealed enclosures and has some recommendations/tips? I love lows. Had an 18" Q tuned to 28hz for a while but the box is just far too large and heavy for me. Im thinking of building it 1.5-1.75cuft while empty and putting some poly fill against the inner walls... not sure how the box size is affecting the woofer's output exactly.
