If its so basic, why doesn't everyone do it? Why isn't everyone putting up great numbers? Why has 99% of this forum spent more on their setup as a whole and can't come close to a 150... and if they can, not at this low of a note. We are talking a 150+ even at 38hz....
This box wasn't $300, just a btw... This particular box was only $150. He provided the ports and didn't want carpet, and it was also a local build. I would charge exactly the same to anyone under the same circumstances.
I ask you this... lets just go off the vid here:

approx recreating the system would be:
2 type R 12's - $250
nine.1 - $300
box design from these forums - $15
(assuming you have the facility/ability/tools) materials for the box - $30-50
Also factor in the hours it will take to make a box, the less experience you have with wood the longer it will take.
That is about $600, could be as much as $700 or more if you have to buy the tools to make the box. Not counting the hassle of building it, going to the store and getting the wood... how much is YOUR time worth?
Now he pulled a 139 @ 48hz with the above setup, just about.
What he COULD have gotten if he would have planned on the TCAB box straight off is.... :
One type R 12 - $125
nine.1 - 300
TCAB box - ~$225 shipped
No work... get the box and put it in.
That comes to about $650, and thats that.
With a setup like that, he pulled a 142.9 (before he got the other box in there) at 46hz. If the box was designed to be in there on its own, the score would have been achieved at a lower note. I'd also like to add that the box designs are more advanced at this point... so now it would be even louder.
Now can you see where the VALUE of the box comes in? He would have been louder for about the same amount of $... saved space in his trunk... and had less hassle. It would have also been louder and sounded better from the start.
To the DIY guy who wants to sit in his garage all day building boxes, there is no point in buying a box... but to the guy who just wants a LOUD setup and doesn't want to deal with building or CAN'T build... a setup designed around the box saves $.
Also mods, don't take this as advertising... I just feel the need to stand up to the shyte being slung at me and my business by presenting a real world account //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
