[QUOTE="David12460, post: 5362131, member: 584046"] If anyone has some free time and would like to help me with designing a enclosure I would be greatful. I struggle designing ported enclosures. I have 4 Sundown E8's on the way and want to build a ported enclosure tuned roughly to 30hz. This will be going in a ext cab S10. I would like it to stretch the length on the cab. Size to work with: These sizes can be modified to be less but no more. These are the max dimensions I am willing to give up. 45'' Wide 12'' High 15'' Deep Here are the specs PARAMETERS AND BOX SPECS: Re = 3.37 ohms (4 ohm nominal) Fs = 34.9 hz Qes = 0.5323 Qms = 6.93 Qts = 0.4943 Vas = 7.6 L BL = 13.3 N/A Mms = 127.7 grams Cms = 162 um/N Xmax = 12mm one-way linear (70% BL method) Rated RMS Power = 200 watts Depth = 4.25" OD w/ gasket = 8 5/16" Cut Out = 7" Sealed Box: 0.280 ft^3 w/ F3 of 50 Hz (Qtc = 0.707) Ported Box: 0.60 ft^3 tuned to 30 Hz F3 of 25 Hz Thanks [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
