does any one know of a box building program that works with apple computers ? all that i have found are for windows

i got a kicker l7 15 dual 4 wired to 2ohms into a hifonics brutus 1200. i just got my box built by one of my buddies who owns a shop. the box is roughly 5 cubes tuned to about 35hz pretty sure. i got everything together last night and spent all day today playing around and trying to tune it and it just does not want to put out those real lows in some songs. sounds like its just blowing air. None the less it tears apart the mid to high bass. i dont know what i could do to change it up maybe rebuild the port or something. not to good with this stuff thats why im asking you guys. inside of box dimensions: width 39 height 13.5 depth 18.5 its got 3 in wide slot port its just…

Hi guys Trying to get started on enclosure this morning for a Jeep Cherokee. Want to be able to see out of the back window. Listens to Metal/Rock. Tuning ~ 35-37hz okay Amp ~ Rockford Fosgate 40001 I now have these max internal dimensions to work with before speaker and bracing displacement. 40" W 23" H 24" D Thanks for any help Shizzzon I've sent you a new PM Goal is doing what it takes to get max air space so a ported enclosure is possible. Subs up port back. Box will also be double baffled. Can anyone double check my work and see what kind of port you come up with. Probably one rear chamber and one big port slotted and vented. Thanks in advance, Joe

Just to start off, I'm building this for the heck of it and recently picked up an inexpensive Memphis audio 15-ms84 to build a box around. This box might be placed in a car just to see what it will do but will stay mostly in the office. The pictures should give you an idea what I'm trying to do, and should show most of the specs of the box. Basically using an 8.25" x 1" slot port that is 23" in length with a tuning around 38 hz. The box volume is .59 f^3. The response curve seemed to have an nice flat-ish shape that hopefully will make it sound 'full' to the Fs. If I'm doing something completely wrong, please let me know - Gently please. Thanks John

Welcome to the fabrication forum......I am the Mod of this section.....Please keep it clean and respectfull in here.....and most of all...enjoy....

hey all just built my first 6th order and it came out beautifully. this was for an fi x 12 and pounds for what it is and what power im throwing to it. and illl be sure to have picks of it upp tomoro. also did my blowthrough and that was a succes as well. just wanted to say thanks for the help

Im tryin to see if anyone can custom fiberglass me some door panels, entire door panels for both of my doors of my car. I know some companies locally that do it but they charge extremely, i mean EXTREMELY large amounts of money for it. To give you an example, they charge $1,500 to do a 14cuft wall in my car.... i dont know why they told me that a while back but that's not what i wanted from them anyway because i know how expensive they are. I'm lookin to spend no more than $300 per door. Is that too low? I can't find anything for a Scion tC.

Just bought 2 of the old version BTL 12s loaded with the 3rd mag and everything. But Im trying to save space for more room for my batteries and amps. My amps are going to consist of a T40001BD and a T5002. Im going to do a semi blowthrough in the trunk of my Thunderbird in which the back seats do not fold down but Im going to cut out the rear armrest and use it to help let bass escape into the cabin. I wanted my enclosure to be subs and ports forward sealed off from the trunk. I'll have about 8" between the back of the seat and the front of the enclosure. My deminsions will be (double baffled) 15"H x 38.25"W x 23"D. After sub displacement,bracing, and 45 degree corners (r…

in a hatchback, anybody personally experienced a setup where the subs were within 3.5" from the glass producing over 2,000w of power? Is there any danger or am i worrying too much?

Okay got 4 Old ass but brand new in box, pioneer SVC 150 RMS TW-W33C subs from the local shop, for 100 bones. I figured it'd be a good start for 4 12's to mess around with. Well i built a Box the size of the Explorer XLT's cargo area. So thats 30" Deep, 40" wide, and 16" tall. (exterior demensions). Anyways made a port thats like 3" wide (give or take), and about 5" deep. Well what did I tune this thing to?? I have no theile small parameters, for the subs so it was just a shot in the dark for this project. Its almost as good as my 2 Vipers in 47hz boxes made for DD's. Anways this setup is prolly going soon. I am trying to get jcc's 4 Vega Vega 12's to put back there next.…

Yup I finally made a decision and the sub is in the mail!! My sx12 will be arriving soon and I need to build a box. I want to give it about 2.5 cubes after port displacement tuned to 34-35 hz. Building the box is not a problem, I got that part down. I just need help figuring port area/length. So any way you guys could help out would be awesome!! Thanks Tom

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!

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 …

I decided on a vehicle, and am just waiting for my check; In the mean time, I have some money set aside to start on the system in the new truck. So far i've decided on the equipment for the front stage (Zed and Crescendo speakers) just not how many lol. I think $1250-1500 is fair for a setup; and that's what i'll put towards the subs. (tax money will pay for the front stage ) My goal is as loud as possible below 40hz. I sold my BTL this morning, bittersweet, I only got to enjoy it for a few days before losing my truck But the new plan is a bunch of obsidians on a hifonics BRX 2400. I'm thinking four 18's, 24cubes @ 30hz. That is about half the budget there, plus…

Bass race death match was awesome to, I'll get the video later. Anyway, I built for this thing and I won, it ended up with a 146.1 for a 5min average. It could have been higher but there was no need to turn it up (as you'll see i started at a 148 and backed it down) This was taken this past weekend in Augusta, GA at one of the db drag events. Car off, 5minutes, four loudest street cars at once! I started high, and then turned it down just above the guy next to me. The guy with crx got a late start, so he only did a 138(burps a 151), the guy in the red truck had 2 L510's and a Orion 1200D and held a 138 for the 5min. Not bad! It was a looong five minutes sitting inside …

Please contact Josh at http://www.facebook.com/#!/josh.w.hart or http://www.facebook.com/#!/groups/449888281732464/ and PLEASE tell him I sent you! He is truely a great guy to deal with. I was sent to him from Duran. He responds very fast, and is easy to deal with. He has just finished up my design for my 18" SSA Evil and really went above and beyond my expectiations. This is not just any ordinary designer who build an enclosure around your limited space. He actually aims for your goals and utilizes your intended goals into every aspect of the enclosure. When you message him, I would suggest to include any additional information that you may think that could help the desi…

Hi all. Just wanna show you vids of my new daily system. As shown in title we have 12" Fi BTL N3 and MB Quart Discus 2000.1. Sub connected 0,7 ohm. Box about 2.2 cuft tuned 36-39 Hz. Battery 65 Ah noname . They do more than i expect . Feel free to comment ! Watch until the end and use HD.

I just got done discussing with someone what i am doin with my wall in the car and have found a solution, a very cheap solution. I need to have my wall flared on the inside and outside to try and achieve higher pressure levels. My port area is 16.5" wide x 11.25" tall. Look at the bottom pic to see what a Bellmouth port looks like- for my application - There is a guy around town that can make me ANY custom size, flare, etc for my wall so i told him to hold off for a couple weeks while i test other things before i venture in flare port testing. I have some questions though so i can get him to make the proper size. The outside flare can stick out of the box a MAXIMUM of 5…

Just waiting on getting my two 15" icons and, since I have nothing better to do I was wondering if there was any box type or orientation you'd like to see me try in my 2004 Impala. I'm going to try a ton of different boxes and orientations with a lot of testing to see what works out best in my application and I wanted to have some fun with it. I'm NOT doing a wall, but ill be pretty open to anything else you'd like to see me try. I might actually end up using your idea if it works out the best! -Mike

hey im putting 4 l5 15's into my van but was wondering iwhich way i would be louder, if i had 2000 watts going to all 4 so it would b 500 a piece or just do 2000 and only hook up two for 1000 watts a piece , in my spl class for this year i cant exceed 2000 watts

I have a sundown sae 1200d, which can handle 1500 at 1ohm..... I also have a 12 inch fi bl fully loaded. Would i have to get an extra battery or do the big 3. Will i be fine if i just do the big 3 upgrade? I have a zero gauge amp kit.
