for the specs they recommended? First I want to say Thanks in Advance to anyone who can help me with this. I don't really understand car audio too well, so I am having a professional company online build my box for me. I hear the box is crucial to getting good bass from your system. I want to make sure I get the correct box with the right specs...since I just paid a lot of money for my sub, and it's a very high quality sub I hear...so I would hate to see it go to waste. Here are the specs given by the company (Treo) for my particular 12 inch sub (and I only have one sub) Ported- 2.25 cu ft net, 35 sq ft vent, 18.5" long, F3=31.8Hz
--Now when I went to fill this info out on the custom box website, they never had anywhere for me to put in the 18.5 inches long for the port. I will copy and paste here what I see on the final page right before I am about to place my order for the box- Subwoofer Information
Subwoofer Size: 12 inches
# of Subwoofers: 1
Cutout Diameter: 11.125 inches
Mounting Depth: 6.375 inches
Enclosure Details
Port Type: Slot Port
Port Tuning: 31.8 Hz
Port Dimensions: 13.125 x 2.75 inches (Height x Width)
(port length is not displayed) NOTICE HOW IT SAYS PORT LENGTH NOT DISPLAYED?? I WAS NEVER ABLE TO ENTER IN A PORT LENGTH...so will this be ok for the sub? I don't understand..unless the Square Inches of the port automatically determine this I would assume?
Port area: 36.09375 square inches
Number of Ports: 1
Net Internal Volume: 2.25 cubic feet
Port Volume: 0.9288 cubic feet (includes displacement of port materials)
Subwoofer Displacement: 0.2000 cubic feet per subwoofer
Total Internal Volume: 3.3788 cubic feet ($15.75 extra)
Number of Terminal Cups: 2 per subwoofer ($5.00 extra per subwoofer) NOTICE HERE I SELECTED THE OPTION FOR 2 TERMINAL CUPS...WOULD YOU RECOMMEND THIS?
Front Baffle: Dual-Layer Front Baffle - 1.5" Thick ($15.00 extra per subwoofer) AND HERE I SELECTED THE EXTRA THICKNESS OPTION. IS THIS THE RIGHT CHOICE? OR SHOULD DO I NOT NEED THIS, OR WILL IT JUST TAKE UP MORE SPACE?
Box Dimensions: 26.5" (w) x 20.75" (d) x 14.625" (h)
So, that is basically the custom specs I put into the website, so they can design my box accordingly. I just want to make sure I get the correct box for this sub, so that is why I am asking these questions. It seems that I put everything in right. My main concern is the port length, which it never did give me any option to enter it, and it won't display it so I don't know how much it is. And then about the woodthickness for the extra 15.00...is is needed? Thanks again. PS- the company/website I am ordering through is called klausaudio.com It's the first site I found that will design the custom box for you. Most sites I see just have prefab boxes.
ONE OTHER CONCERN I have that I just noticed was where it says (and I will copy/paste) ""Total Internal Volume: 3.3788 cubic feet ($15.75 extra) ""
But my concern is that the specs said I needed 2.25 cu. ft net. Why does it say 3.3788 cubic feet? I entered in 2.25 when they asked during my box creation. Maybe I am just a little too over cautious, but just want to make sure this is right and that there are no errors here.
