SPL & SQ / Fabrication

I have a 1989 Dodge B250 Van. I removed the backseats and built a platform to hold a setup I am getting ready to build. I will not be building a wall. The subs were going to be facing the back of the van and my plan was to have the port on the back of the box. Do you think that would work properly or should I move it to the front. The speaker box will more than likely 21-24cubes and tuned around 32hz. It is supposed to be for 4 18's or 6 15's. I am leaning towards the 15's.

Whats the best agent to apply ur carpet to your enclouse?

plan on making a box for a box for a DC level 4 18" what do you think?

So i was trying to look for some pictures of a box terminal made out of ring terminals, nuts , and bolts. So i can have a idea on how to do it. Thanks.

so i did a quick little search, but i am a bit slow and tired and i didn't find anything. i haven't built a box before, nor helped anyone build one.. but i've pretty much decided for my first box to tune it at 32hz, and on the Fi section of the forums they recomend "1.8-2.5 cubic feet".. what does each mean, like how do i know what i prefer. basically waht i'm asking is when the box is smaller, what does that mean? tighter bass? higher notes (roughly)? what. and then it recommends 32hz, so i'm going with that.. but how do i tune it to 32hz? i don't understand how to tune it using the box. or is it a setting on the amp/sub. if you couldn't tell i've never done this before,…

This is my most recent sub enclosure, I designed and painted it. Looks way better in person too. Tell me what you guys think of it. Thanks.

wtf makes it a "nice" or "right" enclosure? like everyone says that my 12" Q will sound amazing in the right box. how the hell do i find "the right" box without building multiple boxes? any suggestions? i just see it everywhere but i don't know where to start on building a good box to get alot out of the sub? i know the obvious, such as size. if iw as to go sealed, wouldn't pretty much any sealed box sound the same? if they were the same cuft that is. and i know theres alot of variables for ported boxes, but how do i know what sounds better then others? i just wonna do it right the first time. i'm currently in a 1.5 cuft sealed enclosure that a local audio shop "custom" b…

ok so one night i was sitting around thinking up some new box ideas. i really want to have my sub facing forward into the cab of my car, and have the port be on top of the subwoofer. so i was doing some concepting and came up with this, Pdf of box idea. I just want to know if it will work before i start building i forgot to put notes so.... notes: 1. double baffle front plate 2. round port edges 3. 2.8 ^3 feet of airspace after all displacement 4. 3/4" mdf or particle board used. its going to be firing forward with the trunk sealed from the cabin. thanks, Anton Miller

my sub amp is a kenwood excelon. u cant bypas the xover... right now i just cranked it 200hz at a fixed 18db slope. and use an 80 hz 18 (or 12) on the hu. i forget if the 2 frequencies combine or if there separate of each other.... i think it was explained to me once awhile back that they somehow combine so i would have like a 75 hz with 36db slope.... what would u recommend i do...

I'm building a ported box at 32hz for my 15 BL, it will be 13 3/4 Deep 37 1/2 Wide 20 1/2 Tall. I have never built a screwless box. So what glue will i need? any tips on how to go about it? I have built about 5 boxes and they came out great so i do have the "skills" Thanks, Justin

Been bumping my 15" SSD for a while now and I'm still loving every second of it except for one thing. The rattle. Its not the trunk rattling its my back deck speakers, and the reason their rattling so bad is because the sub is firing up towards them. My dad had to buy a special bolt and locking nut to keep the screws from backing out because every time i listened to it the screws holding the back deck speakers in backed out about 2 inches. Its really annoying, you either have to listen music with the bass so low it doesn't rattle them or so loud you can't hear the rattle. *And I'm not taking the back deck speakers out they help fill the cabin with highs So here is my plan…

Just a for instance: Say you have an enclosure 40" wide x 32" long x 30" high, The port is 38.5" wide (facing forward), 6.5" in height, and 24.5" in length - tuned to approximately 34Hz (I'm assuming a driver XMax of 20mm.) The Net enclosure volume is 14.40 cubes, less driver displacement. You have the option of placing (4) 15" subs on the top baffle, or (9) 10" subs. Which do YOU choose, and why? What subs would YOU do? Roughly 1.5 cubes each for the 10's, or 3.37 for the 15's. Either way, it would be possible to run whatever amp at 1 ohm Mono - Strapped SAZ3500's, anyone? I'd be VERY interested to see/hear/speculate what the XCONS would do......

Looking for a tutorial or some instructions on how to build the covers for door pods. I can build the pods, just was wondering how to go about making custom grills/coverings for the pod. Thanks for the help

whats the max dimensions that will fit through a trunk of a mustang trunk opening... wiered ass trunks

I was told by a former "audio guy" that althought 3/4 MDF is used in car audio enclousers, 3/4 partical board could be used to reduce the weight of the encloser. How tru is this?

Hi Everyone Need Advice On How To Make My Box Look Good. I Want A Quick Project Do Do Under $60 Carpeting,Paint,Stencil, Spray On Bedliner ? Let Me Know If You Have Any Ideas. Here is A Pic Of The Box. Thanks ~ Kent ~

for thoes who have compeated in iasca or usac sq the question i have is where should the center of the stage be in the car. my personal prefrence is center of the steering wheel. i want to know if it should be right in front of you in front of the steering wheel or the center of the dash as you would need to look at the middle of the dash to imagin thats where the voices are coming from. which is the correct answer for competition i am runing 3way active and have time alignment to play with

How could I brace my port more, or do you think it needs to be braced? Here is the bracing of the entire box, but it is also for an idea of what the port looks like... also, do you think a 45 would be helpful in my port? I don't think it would make much of a difference....

I have a 2000 Toyota 4runner.. Throwing in 4 old skool 15" ROCKFORD FOSGATE HX2. Sorry, I had to put the name in caps for respect!! Anywho, I got some measurements here... I want the box 40" (width from wheel well to wheel well) x 36" (length from back seat to back door) x 20" (from bottom to top). So measurements are 40"x36"x20", outside measurements (roughly 16 cubic ft) . Here are my questions... Has anybody had 4 15" subs facing down towards the floor and had rectangle port facing up? My reason is, if you look real close at my pic, you can see 2 6x9 Kenwwods bolted on top of box. Also, I usually haul wood and crap for my work and would really hate to get a sub busted…

I recently purchased an A.P. Axis 15 and was suggested to make this box. Box is to be 3.0 cu. ft. net and to use 4 - 4" pvc ports. Because of box dimensions I'm not able to use flare ports so this is gonna be straight 4" pvc. I'm told the beauty of this type of box it the ability to change tuning and also seal up the box using plumbing inside pipe plugs. A ported and sealed box combination. My concerns is port noise. When I brought this up I was told that I would not have that much and that I would certianly not hear it while playing normal music, just on bass tracks. Is this accurate information? I think this box concept is great but if it's so great why isn't …

Well I was bored so I made a couple vidz. Hope you enjoy :bigclap: Up first is a vid showing air movement from drivers window Breaking the lil guys in. Strange noise is not the subs. The closer the mic gets to the port the worse it gets. Lastly my no flex flex vid LMAO!! Will post more if ya want!

Well the classes are now set and instead of using 4 ohm ratings since there are too many Grey areas I am using rated maximum rms power at the amps lowest rated ohms. That way a 1 ohm 1000 watt amp is still in the same class as a 2 ohm 1000 watt amp. This will also make people see the difference between the swap meet power amp they bought compared to a real rated power amp in the same class and should bring those customers to the retail store instead for their next purchase especially if the retailer explains why his B.S rated amp just lost to the real power rated amp.The classes are more geared to the normal customer more than the bigger powerhouse systems but still allow…

I am wondering if the Mach 5 SPL-12s would be any good in a T-Line? I have been told they should be good, but the fs is sorta high. I am planning on doing this with my camper shell but with a different box... the box can run the length of my truck... I plan to make up some metal frame for the box to sit on inside the bed. Having the box above the floor will give me room for my air ride when that gets installed..

a great ssa member put this togather for me.... thank you sir!
