SPL & SQ / Fabrication

Looking to get max spl in a trailbaler on a cadence a7hc. 1200 watts 1 ohm. I would like bass on all types of music. I have a 4" aero port laying around that i could use. Shoot me some ideas.

Made another video showing the rest of the kerfing process!

So I'm doing a build in my 2003 Dodge Dakota crew cab of 2 15" icons and would like to reinforce my roof. I'm getting 3/4-1" flex on one 10" incriminator I series and also headliner slap and it drives me crazy. I have a bulk pack of dynomat extreme I got for like 20 bucks. Would 3/8" MDF with kerfs And lots of pl then dynomat between headliner and wood be good? Just want to cut down roof flex and stop headliner flex. Any suggestions? I would rather not have to order stuff if possible as I'm tearing truck apart this weekend and shipping is slow Thanks

this is the box i decided to make for my 2 sa12's am i ready to cut it out or is there anything else i need to do? and does the cut list take the port into account? or is that a separate cut?

Hey guys i'm building my first my box for three fi bl 12's and want to tune it to 31-33 and was wondering which would be better? Sealed,ported, or banpass?? Any suggestions would be helpful

Just looking for some help I guess. Mostly with the stock classes. The organization i was preparing for is looking like its just about dead (dbdrag). So im thinking it may be beneficial to build towards the rules of iasca. Anyone with experience competing in this format, I wouldnt mind a bit of help.

I'm looking into building an enclosure that measures 34W (left to right) x 18.5D (back to front) x 14.5 in height. The speaker is going to sit on top, port firing back. This is an L port design. The port will be 3 inches wide. My question is, if I want to tune at 33Hz how long would the other part of the port have to be (the one that runs across the back of the box)? I used RE's calculator for my last box a few years ago and it couldn't catch the lows for nothing, so I know something is not accurate about that calculator. If someone could help me with this, I'd appreciate it.

ok so im designing a box for two 12 inch xcons, ported going into my 2007 scion tc(Hatchback). Right now i have a decent box but its time for a rebuild. My box right now is 40.5 inches wide, 20 inches deep, and 17 inches high behind the rear seats. Its tuned at about 29-31 htz(not too sure). It does a 143.7 on the meter sealed up on the glass. No deadening, no beauty panels. But my concern is that my port is an Lport on the drivers side, it only goes halfway across the box so one woofer is above the port and the other is not. Im worried that the sub above the port is loading off of it and the other is not. If it is i want to fix this, so a rebuild is underway. It has bee…

I am looking for someone who can design an enclosure for my trunk, max dimms are: H=14", W=38", D=38", Tuned to 30hz, Will be using 7000wrms+. Thanks.

Hey guys I have a Fi BL 15" fully loaded woofer on the way. I will be building my box very soon here. I'm going to be running a Sundown 1500 D amp to it. I will listen mostly to low HZ rap or bass songs. I am looking for 32 HZ. Few questions: - Can someone give me some measurements for a ported box that is meant specifically for a BL 15" with 1500 RMS going to it? - I have read that this sub woofer recommends a 3-5 cu ft box. Does leaning towards 5 cu ft box have any benefits in SPL? -Any internal box bracing necessary with 3/4 " MDF wood? - Any cotton material necessary inside the box? Thank you

This is what i have came up with, i have the wood, tools, and these are the specs I found most best for the sub and is wondering if this would work prime with the AA mayhem single 12" dual voice coil. http://imageshack.us/a/img22/3130/subspecs.jpg

I am looking for someone to build me a box for my SSA Xcon 10. Looking for something that will hit on all types of music. The sub will be in a Trailblazer with a cadence A7hc at 1 ohm so around 1200 watts. I would like to keep the size down as much as possible. Ported preferred. If anyone wants to build for me pm me and we can work out a deal. Thanks

I got everything ready to cut untill I forgot... What tall is the mayhem 12". I have it ordered but don't have it yet. On site says mounting depth of 7.75 inches. I don't know what that means.. Help pleaseeee

making a custom enclosure for two sundown sa12's. which would be the best box for them? no dimensions yet, not quite sure how to calculate the volume of a ported box. --obviously the port is not to scale with the rest of the box, just gives an idea-- i felt i could draw them out better than explain them, even though they are the common boxes. feedback? suggestions? everything helps.

Have a mock up design 6.73cubues net after port and everything wondering if i really need 29inchsa of port per cube or is that oclver kill trying squeeze 7cubes net orafter more ifthe possible. Also running a crescendo 3500bc at 1ohma on strong electrical so ill have the zcon moving displacing a good amount of air. Just a simple port area question dont want waste space .

Little problems nothing serious. Built enclousure for some 18inchrolling zcons limited on space but couldnt pass the offer up on some z's. Box is small for ported box and tuned high with a smallamount of port are, basically if you could mess a box up and screw yourself over in output this is the box. 180inchs of port area withc4.5cubes per 18 tuned at 40hz not that happy with the output even on a .5ohm load on a sendo with electrical back it up. My question iss would i see a day and night difference if i built a single 18 box the biggest i could build out of my space? Pics of the franksteinvbox xustom finish on it.

I want two 15 in icons in my trunk but idk if i have the room. I want a ported box. Trunk dimensions are 4x3x1.5. Amp is crescendo bc2k if anyones wonderin

So I will be ordering an OA-12v2 D4 very soon after selling my current system (Upgrading from a Fosgate Punch P2 12, 2011 model). I have a Rockford Prime P500-1d to work with, so the sub will see just over 500 watts. I have read in many places that the more power, the smaller that the box can be, and the less power, the larger you can build the box... generally. So I was thinking of doing a 2.5 cuft enclosure for the OA, on the 500w. It will be going in the trunk of my 2000 Civic sedan, most likely sub back, port side. Does this sound appropriate? Is there another way I should approach this? The box will be tuned to 30Hz via 4" aeroport. Thank you for any help, and I apol…

i have no experience in enclosure construction at all and have been tearing through forums for some helpful advise in enclosure designs. I am pretty confused at this point about some things and was wondering if anyone could clear it up? I am under the impression that if a certain speaker is in a smaller enclosure that it will handle more power and a larger enclosure will be more efficient (less box rise). so if that is true, will they be equal in spl if they receive the same amount of power (after rise) rather its in a "smaller" or "larger" enclosure? i have also heard of people covering ports to play with their tuning, is this just a solid cover reducing the height/width…

Wonderin whats.better for 4 12 sa's d4.They will be going in a 99 crownvic.thank u in advance

In my 2003 tacoma single cab and bench seats doubtful i can get two tens ported. Car audio dealer told me it wouldnt sound good with ports on side of box. So am think of one ten ported or two sealed

I want two 15 in icons in my trunk but idk if i have the room. I want a ported box. Trunk dimensions are 4x3x1.5. Amp is crescendo bc2k if anyones wonderin

I need a box for.4 12 sa ported to be put in a 99 crownvic can anybody.help me this and a set price would be nice i live in fla

looking to do a new box and wanting to know what yall think the best kind of box i sould do if im wanting to seal off my trunk, i have 1 15" zcon on 3000 watts, i was thinking of doing a bandpass where the subs sealed part of the box is where i open the trunk and ported through where my back seats fold down, any questions? sugestions? im wanting to do this because my box now is ported back and sub back and my trunk pretty much opens with the bass and can feel mass air coming out so i know i can get way louder if i seal my trunk off

I am thinking about getting someone to make me a custom box. Anyone know anyone that does this?
