Largest Singl 12" Box you Have Seen?

Just wondering whats the largest box for a 12" you have seen. Because I saw one that is about 9 or 10 cubs and the port prolly was 1 1/2 ft w x 1ft h x 4ft d..........It took the whole back of a 2door tahoe! And the sub that was in it was a big bang 12".

Folded horn or Transmission Line enclosure. More than likely a T-Line of some sorts.

8th order could possibly be bigger than that, but off top a 4th order on a 12 is the largest I've personally seen.

Ummmm. roughly 6 cubes.

9 or 10 just seems crazy to me. My box for 2 15's isnt even close to that big.

Unless its a tline.

i had one that was just under 6 cubes and i thought it as to big i couldnt imagine something bigger without going bandpass

One of my friends had a single Savard 12" in a bandpass enclosure in the 90s. IIRC the external dimensions of the enclosure put it at 9 cubic feet and it barely fit into the trunk of his Chevy Cavalier.

Ya this guy built the box to fit in the bed of his truck. I havent got to see the inside of the box so i dont know if its a t line or not but its big!

Keep in mind, the box may have been 9 cubes GROSS. For all you know, he could've have like 90 sq. in of port area and to be tuned to whatever he wants it would be super long and take up a shitload of volume in the box. There also might be an extensive amount of bracing and maybe double sided walls on the box which would leave even less net volume for the sub. With all those displacements taken into consideration, that may be only seeing 5 of those 9 total cubes which isn;t all that hard to believe. I was looking at the stats for the Soundstream T5 woofer and they reccomend 2-4 cubes, so for an extremely beefy high excursion 12", I'd believe it.

Drrr... I fail at reading, disregard my last post. Well YEAH! Of course it would have to be that big of a box, that port displaces more volume than my box has total, so the total volume would have to be HUGE for the sub to have sufficient volume.

what kind of 15's do you have i have my single 15" in 8.008 cubes and it gained me 6dB over a 3.78 cu box. (both ported)
