any more pictures of enclosures? I want moooooorrree!!!!!!
also I want to build an abc for a 1 15w3 (daily driver box) I got about 6 or so cubes to work with after displacements. unless I face my sub and ports up, then I have more.
Mr. Flamboyant any tips for a 1st timer?
thanks,
scooby
p.s. will it still be pretty loud if I face the sub and ports up? I love pressure

Hey all, How well would a ABC box work for a 18" Stroker? I was in the middle of redoing my install (took out my wall) I just want to do a back seat install so theres tones of room to have fun with. I couldnt get the very 1st post link to work so im lost still on all of this.... Will some one be willing to help me desing a ABC box for my stroker?

Stroker 18" ABC: - big chamber: 4,83 ft^3 (incl driver and port displacement) tuning freq ~27 - small chamber: 2,49 ft^3 (incl port displacement) tuning freq ~38 - all ports: 6"(Ø) 23,3 long. - the big chamber must include the driver and one port.
the small chamber must include one port.
the third port must connect the two chambers. - I don't know how this will sound. but i think it'll be DEEP...

Thats not what I want to do anyways.... Im just looking to build a new box. the ABC sounded different so I want to try it. it would be mounted between the front seats and the rear dash somewhere..... I was just going to do a ported box but why not a ABC its pretty much ported with a kick

yes that is an abc. one thing that i wus told by an abc master (mr flamboyant) is that u should put the third port a couple of inches away from the back of the driver and not as much towards the back of the box.

Ok, so for size what about 5 cu ft for driver chamber and 3 for empty chamber with all ports 5" x 5" x 18" ? this is without driverand port displacment

that's not a 1/3 & 2/3 division... it would need to be 5 cubes and 2.5 cubes... also, have fun maintaining that 1/3 & 2/3 division, when it comes time to factor in the sub's displacement... and determining exactly where the divider board needs to be placed, in order to maintain this division...
its fun playing around with this type of box... i used round ports on my first few... this way i could change out different length ports, and change the tuning.... it helps to have enough airspace, rather than too little.... can make them actually unlistenable (if thats even a word)....

Okay guys, another ABC question. How do I graph the box in winISD? I tried taking the total volume of both chambers and tuning them to the desired frequency, and then opening another box (so as to graph both at the same time). On the second box I made it the volume of the larger chamber and tuned it to 1.9 times the lower frequency. However, when I am graphing both of these I get a HUGE spike a little above the higher tuning frequency. What would be the proper way to graph one of these boxes? Thanks for the help Posts: 68 | From: Tampa, FL | Registered: Apr 2000

Right, but that'll just show the response when the sub is utilizing the entire box and the low tuning frequency. How can I graph it so I can get a accurate graph for all of the frequencys in the subs range? I thought that I could just punch in the dimensions for the larger section of the box and the higher tuning frequency to plot the upper range, but that doesn't seem to be the case... I don't know, I'm confused My entire question is really just this: How can I get an accurate graph in WINisd for an ABC box? That is, plot all frequencies accurately so I can see the response I'll get from the sub/box combo at all frequencies in the box/subs range. I'd really appreciate any help.
this is the box as a whole...... and just the smaller chamber.... to get the response curve of the smaller chamber, all you have to do is enter its volume, and port size (1 port, and 1/3 of entire box).... try it...
the sub 'plotted' in that link is an Image Dyanamics IDMax 12.... a very nice response curve
