Slobalt7 Posted July 24, 2013 Report Share Posted July 24, 2013 This is what I have so far. I am about to draw it up in Sketch up but was wondering if anyone had any tips on how to make it better. The measurements in parentheses are the true measurements of the enclosure aside from the center wall which would be removing .75" from the center of the chamber 2 width. Also if it matters this will be made of .75" Birch and they will be on an AB VFL100.1 (1500wrms @ 1 ohm) at 1.33 ohms before rise. Triple Skar dual chamber bass reflex (ABC) Net volume: 4 cf Port(x3) dimensions and displacement: 4"x12.834" & .1 cf Sub displacement: .1cf Gross volume: 4.9 cf Chamber 1 gross volume and dimensions : 3.036 & 20W x 15.25H x 22D (20.75w 15.25h 23d 3.293) Chamber 2 gross volume and dimensions : 1.564 & 11.75W (10.5w 1.539) Gross box dimensions : 30.5W x 16H x 23D *Notes will have double baffle, measurements account for single baffle(+.75"H) *Orientation will be ports up side by side, subs up in triangle pattern in chamber 1 Yeah, it's slower than your bowel movements.

SnowDrifter Posted July 25, 2013 Report Share Posted July 25, 2013 I'm by no means an expert on this type of enclosure, so I can't really say much... But at a glance: that port area looks looooowwww ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Slobalt7 Posted July 25, 2013 Author Report Share Posted July 25, 2013 I think so too at 12.56 sq in per port tube but any bigger and I can't fit the tubes for the tuning I want. I can't make it any taller and they are about 2-2.5" from the bottom of the box. I figured since they are recomended for .75cf each but I gave them a bit more they could use the smaller ports to an advantage when it comes to cone control at the sacrifice of chuffing. If there is anyone who could help me solve this issue I am all ears. Unfortunately those are about the max dimensions I am willing to go w&d wise too. Yeah, it's slower than your bowel movements.

SnowDrifter Posted July 25, 2013 Report Share Posted July 25, 2013 Maybe a more conventional ported box is in order? I'd rather do a proper ported box than a more complicated box that I can't fit properly. As for port length: why can't you bend it? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Slobalt7 Posted July 26, 2013 Author Report Share Posted July 26, 2013 I have been thinking about it and I am actually going to model removable ports, run my 4" for daily and make some 5" for competition use and model square ports. I can bend square ports easily. I don't like bending pipes, IMO it isn't perfectly linear. Yeah, it's slower than your bowel movements. Link to comment Share on other sites More sharing options...
