reno12469 Posted January 18, 2012 Author Report Posted January 18, 2012 That is it to be able to slide into the trunk. I have an 05 Grand Prix.
reno12469 Posted January 18, 2012 Author Report Posted January 18, 2012 I get Torres calc for the most part. Only part I'm having trouble on is the port.
Joe X Posted January 19, 2012 Report Posted January 19, 2012 Ok here is the design suggestion, check the diagram below to see how parts assemble: Enclosure Specifications: Fb = 37,503 Hz Vb = 4,5 ft^3 Subwoofer Mounting = Flush Mounted External Height = 14 in External Width = 33 in External Depth = 25 in Port Width = 4 1/2 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 27 3/4 x 12 1/2 Front Internal = 27 x 12 1/2 Back = 33 x 12 1/2 Left & Right Sides: Side 1 = 23 1/2 x 12 1/2 Side 2 = 22 3/4 x 12 1/2 Top & Bottom = 33 x 25 L Port Internal Assembly Parts: Front to Back = 14 3/4 x 12 1/2 Assembly sample (generic dimensions): Let me know any comments or questions you may have.
reno12469 Posted January 19, 2012 Author Report Posted January 19, 2012 Thats perfect. What is the reasoning for doubling the front?
Joe X Posted January 19, 2012 Report Posted January 19, 2012 If the baffle is not steady the wave will go out distorted, power is lost and secondary resonances are created..
Sergeant_Skyrim Posted January 19, 2012 Report Posted January 19, 2012 Thats perfect. What is the reasoning for doubling the front? While it probably isn't necessary for the 2 CVR 12s if you ever choose to upgrade you could just re-use the box tbh. It basically strengthens the baffle though as Joe said so that you aren't losing any power, etc Build in progress
Joe X Posted January 19, 2012 Report Posted January 19, 2012 Removing the front internal panel would tune the box to 36.9 Hz.
ZachG Posted May 7, 2012 Report Posted May 7, 2012 I think ill build my box for my 2 cvx 12s like that one, How big is it after port? 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120. Box is 3.5cu tuned at 31.8hz sealed off from the trunk. 14sqft of Dynamat on the Rear deck top & bottom. Soon to be more for doors/roof. Gets low & loud Did a 140.5 Sealed at Battle of the boom in June 2013 dropping to 12.7v (need a alt mines going bad)
