Dajulez Posted April 2, 2018 Report Share Posted April 2, 2018 Greetings all, Looking for advice on enclosure measurements for 2 skar vd10's. I have an 02 ford focus wagon. I'm building a ported enclosure for sound quality. I would like it to play as even as possible as well as low. Though i have a wagon, i also have kids and activities, so the space i'm working with is about 34'Wx16'Dx15'H. I've traded box work for a couple of subs i wasn't using and the guy doing the box work has suggested a box with Net volume of 2.5 ft^3 with the port measuring 10Hx1.25W and 20.125L. Tuning is around 35hz. Does this sound right? I've run this through WinIsd and i wish the modeling showed it would play louder lower. Amp is Skar Lp1000.1d. Also, not sure about the TS parameters for the VD10d4 i.e. the skar site shows different parameters than sonicelectronix. The below sub parameters are from the skar site. Please let me know if i have left out any needed info. Super kind thanks in advance.

NorCal SPL Posted April 3, 2018 Report Share Posted April 3, 2018 We did a build for 2 of these in a 63 c-10 sealed behind the seat on a skar sk1500.1 at .5 ohm, and they sounded great! Since you are running the 1000 at 1 ohm, I would suggest going a little bigger than the recommended 1.25 cubes per. I personally would go with 3 cubes for the pair and have the port area per foot in the 13-14 range. www.LowHertzCarAudio.com IG: LowHertzCarAudio Facebook: Low Hertz Car Audio www.lowhertzcaraudio.com 2015 Top Dog Champion Limitless Lithium West Coast Warehouse Link to comment Share on other sites More sharing options...
Dajulez Posted April 3, 2018 Author Report Share Posted April 3, 2018 Thanks for the quick reply Norcal. Is that 3 cubes net? Link to comment Share on other sites More sharing options...
Joe X Posted April 3, 2018 Report Share Posted April 3, 2018 From the specs suggested to you 2.5 net @ 35 Hz would be OK where it goes wrong is port area 10x1.25 = 12.5, it should be like 16 square inches per driver or 32 square inches for both on rated power, since it's a larger vehicle and smaller low power subs you may not get loud enough, at the risk of being peakier you might want to try 3@34 with 34 square inches of port for improved output.

Dajulez Posted April 3, 2018 Author Report Share Posted April 3, 2018 Thanks Joe X. Ok, I'm willing to commit the space needed for 3 cubes. Would you be willing to suggest some dimensions? Link to comment Share on other sites More sharing options...
Joe X Posted April 7, 2018 Report Share Posted April 7, 2018 So here is a suggestion, very close to your max dims, power: to sub(s) rated, amp subsonic filter to 31 Hz, minimum port clearance 2 3/4", figure is just an assembly guide: NOTE: box is subs up / port back, best if the box is placed close to the rear gate.
