SPL & SQ / Fabrication

I have an '04 focus Sedan and I want more midbass. I currently have some walmart pioneer 6x8s in the doors but I just bought some MLI65s and some peerless 2" fullrangers and I figured while I am taking the doors apart I should probably fix the giant holes. My doors look like this: http://www.reversestress.com/other/FocusDoorb4_293.jpg. Well not exactly, mine are red and they still have a bunch of foam on them. But anyway, my midbass sucks. How do I cover up these holes so I can better separate the back wave from the front wave? Oh, and I just bought an SAX100.4 to power them.

I have been pondering on what to coat my wall with. I was originally going to go spray paint but motha f that. I want a plasticy rubberized coating on the box. My friend suggested herculiner. Have any of you had any experience using this stuff? Is there something better that I can use that will work good?

hi, i am thinking about having woodlawn Cabinetry build my box for the 2 12" Icons and i am wondering if anyone has had any experice with them. i would build it my self my i have no tools and he only wants 205 dollers for it and thats with it carpeted and i wanted the baffle to be laminated black.

Heres me covered in sawdust Routing More routing O Bracing Triple top facia!

Can someone check these calculations? Height:20 Width:38 Depth:14 Port Length:25 1/8" Port Width:3" These are externals. Thanks for any help

I'm just looking for some pointers on where I could look for reputable information on designing 2 way passive, 2 way active and (after some practice) eventually 3 way active front stages. Just stuff like, what to keep in mind as far as driver selection, particular features to look for when choosing a certain driver, and how to design passive crossovers. I was daydreaming and hit a roadblock when I realized, what the hell do I even know about a quality front stage? I can't say much at all, other than, deaden, and airseal the speakers. So I feel like it's time to start learning, might even have some applicable tips on hand for when the new truck is ready I'm plannin…

Would this be a good box for 2 xcon 12s running a crescendo bc 2000d I'm planning on running it at 2 ohms because I'm hoping to run stock alt with an extra batt. in the rear for now. I was hoping to run sub and port forward sealed from the trunk so my max height is 18 and width is 32 and that's real tight. If someone else has done this I would love to see pics for reference. http://i1257.photobucket.com/albums/ii511/trpkkd/accordbox.png

anyone in here ever deal with Digital Designs or have a few M1 amps layin around?

so i think i wanna make some new boxes for my 18" BTL's they sound great in the boxes there in right now but i think i can gain a little more output with some new better made boxes. right now there in a 2000 dodge caravan. the boxes are 8.756 cubes tuned around 32-33hz sub up port up. i have been told by a friend that also runs 2 15" btls in a caravan that sub up port up does not really gain the maximum potential out of the cabin. so i was thinking about making the new boxes sub up port back. what do you guys think about differant setups like sub up port back sub up port side sub back port up which one do yall think would be the best? and can any one explain what port off…

hey, im going to be buying a VW rabbit in a couple months cause i got accepted to my #1 choice university!!!! i got a scholarship so now i have about 10 grand saved up plus i'll take out a student loan and im gettin paid to go to school (1600 bucks a month). I currently have a Fi Q18 tuned to 28-30 hz, and i hit 145.2 on my first try with some music. Im looking for some help on deciding what the best setup would be for a hatchback. Im thinking 2 12" BTLs with about 5000 watts. im really excited to get this project goin. my goal is to break the 150 mark but music is what the stereo will play, no farting. any help is appreciated!!!! thanks

I have been running 2 12" zcons for little over a year. 6 cubes 38hz 80cuin of port area. drivers side port all facing into cabin spray foam sealed of family car. trunk build. still have to load kids in back seat. seats fold down. Always been run at 1 ohm. I was using a saz3500v1. when I built that box and tuned it. I recently bought a B2 M1s to run on these subs. 7500w @ 1ohm. with the power increase I was looking for any help with what the new box would require as far as net volume. Looking for help????? suggestions???

I lined my box with fiber glass and mat, and it came out very bumpy, tried to smooth it out and did an ok job at removing some. My question is how smooth does it have to be, does it affect the over all sound pressure.

i will have 2 or 3 amps in my truck to power my speakers. I want to remove them from under the rear seat and build some type of mounting device for them. i have an 8 cubic foot box for my SP4 - could i mount the amps on the side of this box or on some wood attached to this box OR would the vibrations be less than ideal for my amps?

i have a 2005 tahoe with two orion hcca 15.2 and want to build a box like the one steve meade has for is 4 18's here a couple of links...sorry dont know how to put picks up https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&docid=x6V8eu8o53qyjM&tbnid=EQYYPTVbyxj2eM:&ved=0CAUQjRw&url=http%3A%2F%2Fstevemeadedesigns.com%2Fhome%2Fmemberbuilds_5.php&ei=Js_tUumTLOqe2QXA8oHYDg&bvm=bv.60444564,d.b2I&psig=AFQjCNEvJXWf_OhHZbJlaEYPPEtNZET1bA&ust=1391403157918733 http://cs12828.vk.me/u109393749/video/l_a71dab0b.jpg

i got test tones from 20 hrtz to 85 but i fail to find a sweep for free. any ideas?

Starting a box for a friend tomorrow. He has 2 12in kicker cvr's in a prefab box with the ports stuffed with towels because it's way to small to be ported. Lol I will be building a 5 cu box tuned at 32hz. Dimensions are 36w x26d x15h, port is 5in x 13.5in and around 26 in long. It will be 3/4, double baffled and 1in dowel braced. He doesn't have much power JLa1400 (500rms) Should be good for when he can get some real subs and a bigger amp. It's going in a Cadillac deville trunk rear facing. Opinions are welcome., although after spending about a hour making the cut sheet I am pretty set on it, lol. Can post pics during build if anyone wants to see it, should be a huge i…

Hey I want to build a ported box for 2 12" SDC2.5s, but I've never built a ported box....and it confuses me On the Audioque site it says each sub should have 2.5 cuft and that includes the port and sub. But what should the port length, width etc be? I've searched and read up on a lot of stuff and other peoples' builds, but still am not sure what do.

if ny one has ann ideas for a box design that would be helpful please post them!!!! i need a good idea for the SPL competition!!!!

Besides the obvious, what is the difference between front fire and down fire enclosures? Is it just a prefrence issue or is there a sound quality difference?

Alright, so I'm planning a build for my S10 reg cab, and need help designing the box. It's going to be 2 SA-10's in a 2 cu. ft box net, ported, tuned to 33-35 Hz. Also powered by a SAZ-1500. My max dimensions are 50"L, 22"H, 9"D bottom, 5"D top. I made up a box using the torres box calculator, but I was having problems with the port. I'm planning on using aeroports, but they were needing to be too long for that tuning in a small box. Not sure what diameter, and how many I would need. If anyone can help me out I'd appreciate it!

alright, so i have a FI Bl 15" with, cooling,daily, universal d1. I am planning on building a new box because my current box only takes up 1/2 of my trunk which is in fact bad. Due to the trunk and how it is made there are two metal bars coming across the length of my trunk, and it makes my sub box aprox. 1 foot away from my trunk lid, which i think lessens the well initial BOOM, when i had my MTX JH55's in they sounded much louder when they were pushed back so i thought well "why the hell not build my own box" here are the specifications, i even made a pretty picture for you guys. ports from eD. (made in Google Sketchup!) Ideas, comments, suggestions? (some insight from…

im wanting to run a pioneer ts-w304r i want to run the sub to its best potential.the box measurements can be 5 inches deep max at top and 7 inches deep at the top.up to 15inches 45 inches long it will be in a single cab s10 want to be ported if you can help me please thank you

I know it may take some time specially being designed in mm (As I live in Aus) but can someone or as many people as possible confirm roughly these figures??? Also, feel free to use this design and enjoy!!! BOX HEIGHT IS 260mm, 224mm are Internal Dimensions as all pieces join to TOP/BOTTOM ------------ --------- Also I designed this for a 8" Rockford Fosgate P2D28 sub w/ a bit of extra port area for sub upgrades that may have up to 13mm in XMAX such as say a DD sub (P2D28 has 9.5mm)

This is my first go at trying to design a ported box so just want to make sure I got the numbers right. This is for a coworker. The sub is a DD 9515. According to their site it should be 3 cu with 48"^2 of port. Here's what I came up with: 24" x 22" x 15" and the port 3 9/16" x 13 1/2". If I follow the "rules" and make it 20" long it'll be 38ish tune. I appreciate any input you can give. 15" height is to keep it under the window line and cannot be modified. Other than that any suggestions welcome!

If the port area is 32.5in^2 how long do I need to make it to get 30-31hz??? This is for my 12" DCON.
