basketball_00011 Posted October 31, 2017 Report Posted October 31, 2017 Hey everyone. I recently acquired 2 Digital Designs 9512's along with 2 MMatts Audio D3000.1 amps. I'm looking to build a box for my yukon. I'm looking to be tuned around 33-34 hz. and about 5cubes after displacement. DD's site says each sub is .28 cu ft. so .56 cu ft total. My question is does this look right. After displacement will i still be tuned around 34hz? Thanks! Brandon - Bassless since March 2010.
camshairtricks Posted October 31, 2017 Report Posted October 31, 2017 looks good to me . but if it were mine i go with 65 sq of port area an tune it to 30hz
MrSkippyJ Posted October 31, 2017 Report Posted October 31, 2017 You would change his personal preference on tuning frequency by 3hz? F150: Stock 2019 Harley Road Glide: Amp: TM400Xad - 4 channel 400 watt Processor: DSR1 Fairing (Front) 6.5s -MMats PA601cx Lid (Rear) 6x9s - TMS69

ckeeler11 Posted October 31, 2017 Report Posted October 31, 2017 Using Torres I come up with tuning of 38.68. You really using 1.5" mdf?
basketball_00011 Posted October 31, 2017 Author Report Posted October 31, 2017 Well that was one of my questions. Is doubled 3/4" mdf overkill? Should i just do a double baffle? I have heard that these subs like smaller enclosures with a larger port area. That true? Brandon - Bassless since March 2010.

I have heard that these subs like smaller enclosures with a larger port area. That true? I would definitely double baffle but if you do a little internal bracing no need to double the whole thing.
