SPL & SQ / Fabrication

Hey guys! I did a bit of reasearch but couldn't find a good topic about this. What do you guys reccomend for some good box building tips for the best box possible? Not like designs so much (Although if you wanted to post set-ups such as like...Explorer, sub up port back (as an example) that might be helpful to some), but things to do in the box. Things like: Rounding the port edges to flairs 45 degree angles in the corners for standing waves placing the subwoofer so its at the back of the port length where to add braces so that turbulence is minimized (or using rod threads or your favorites) those were a few I could think of as example and I'm not even sure if they're al…

I've got a 2.4 cube box tuned to 30 hz with a 3" aero port. The sub is a Fi Bl 12 getting about 750 watts off a Powerbass ASA1500.1. I went to comp last sunday and did a 136.8 at 44hz. If I made the port tuned to 35 hz, or even 38 hz, would my score go up? I'm not too worried about the competition in my class since I am sitting in 2nd place in the circuit, but it's always nice to be louder.

I was just wondering if anyone can design a box for my fi q 12 that will get low and loud. . . its for a blow through in a single cab chevy old body style and max deminsions are 48 width 17 high and 70 long. . . i just want to get something the will sound like more than one twelve back there till i get money to actually by more ill give 10 dollars pay pal for whoever does this. . . Also i heard 6th order was the way to go cause i have a 4th order right now but i made it to big so i need someone with some sense to make me a 6th BP if possible if not so input please on best box design. Thanks Everyone Thanks, Teddy

Hello, first of all please excuse my english, I am from Romania. I just received a fi Q 15 ( no options ) and I am trying to calculate my speaker enclosure. I want to go for sealed enclosure because I don't have much space in the trunk ( BMM e46 sedan ). Recommendations for fi q box is 2-2.6 cu ft. With my calculations I am about 2.5 but I want to be sure I calculate it right before I give the blueprints to the box builder This is my result, I am happy because it fits inside the trunk perfectly. I made a dummy box to see how it will fit inside the car. Wood is 1 inch thick.

I've recently wanted to start making a horn style box, I've build one on accident before, but didnt know it was a horn box. Now im just needing some advice or basic tips on building and tuning of them.

hey guys i need some help figuring this out.. i have a box with a slotted port.. the port will be 15.5 tall and 4.5 wide the question i have is how deep does it need to be? i want the box tuned to 38 hz the dimensions are 17x30x25.5 (HxWxD) for a total of 5 cu ft im waiting for this i have all of the box cut and ready to be put together other than the port.. btw this is for a mach 5 spl-15 i'll get pics of everything when im done too

What resonant frequency of this car(honda civic 4d 2007)? Your recommendations for construction of the ideal box(spl), for Solox 12!

Are there any SQ comps that are regularly in NC? I see that a lot of you SQ guys are from VA, where do you usually compete? Any local organizations or the like? I have never competed before, so I would appreciate it if someone could point me in the right direction. While I'm at it, what are the different SQ classes, and their requirements?

Have this started on a couple other sites. Been out for awile (5-6yrs). Wanting to get back into comps. I already have 6 MA HK4000ds and a VW Golf hatchback. Also have a buddy selling a couple Americanbass VFL400.1s for a good price. Would prefer to stick with the MAs because I have them. Looking to do 2-15s in a wall. Prefer the street class to save $$$. Have about $3500 to spend. Also what would be some good sub options. I used to run some Apxx's and have seen several motors forsale. Also the RDs I have seen do really well.

It was around 1990 when I helped install two 15"inch subs (i believe they were Pyramid) in a Chevy Cavalier, and installing a 15" MTX in a Mustang hatch back. Both systems were running around 300-400 watts or so and were extremely loud for the time. As car audio has become more popular, I've seen the trend go to the bigger and loudest SPL system you can get (Is there really a 2-way system that can keep up with a 2000-4000 watts sub system and sound good, and not have to have 8 mids and 12 tweets?). The thought of thousands of watts in a system were unheard of. As Im getting older, the trend still keeps expanding. Now you have people installing a sub stage with thousands…

I built my box fits good....but the damn thing is to tall lol so i got to rip it aprt cut the rabbits and fix it pisses me off took 2 weeks to make and i fudgeed up but owell itsmy first box

Big dilemma, trunk car im working with. I have 7.445 Cu Ft internal area for use if i fire up but the box will be removabable so i can grab my spare tire if i need to. Will up firing in a trunk lose me alot of spl or clarity? Which direction should i fire the port if im making this setup. Also for two RE SX 15's how much port area should be used? The port area is a very limiting factor as its robbing the little amount of area i have. The other way i can do is rear firing but i must make a two piece box to fit it in the trunk. The subs would only be 2 inches from the rear lid of the trunk. I gain .2 cu ft from switching but the amount of work would be substantial and i wou…

first thing sorry guys ive tried posting this in the fi section didnt notice it was in the wrong place but im trying to find out the cubic feet on this box and its tunning cause i made it but in order for it to fit i had to chop it down 2 inches if anyone has any ideas or any help it would be great and its for a fi bl 15 and again sorry for the double post

As the topic says. I need to know can't fid it anywhere.

to seal this gap inside my box....if i glass it, whats the absolute BEST way to approach this, so the glass doesnt ever pop off from the bass over time?

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…

Would it be possible to make a transmission line box for 2 18 Q's in an area that's 16" tall x 39" wide x 70" long with an additional area of 22" tall x 52" wide x 10" deep OD? Like this: Would having the subs mounted off center make it not work?

Hey everyone, been a member here ever since I bought my saz1500D last summer, and I Love it! been running it at 2 ohms to a pair of the older type r 12's in a sealed box since then. Around the time I bought the amp I got 2 of the new R 12's and now its come time to try and build a box for them, this is the first box I'll ever attempt so I dont really know how to get proper dimensions, ive tried the re calculator, but im still unsure if im right....so I figured I'd ask. but anyway vehicle is 98 gmc jimmy so space isnt a huge factor if need be, i can take some measurments of max size subs Type R 12 dual 4's x2 amp sundown saz1500D@ 1 ohm I'd like to have subs firing up slot…

I THINK ITS A REAL SHAME THAT TEXAS BASS PRODUCTION GIVES ITS PLAYERS A FALSE SENSE OF SECURITY MAKING THEM THINK THEY ARE BETTER THAN THEY REALLY ARE BECAUSE IF THEY WERE TO GO TO A USACI OR IASCA EVENT THEY WOULD HAVE THEIR ASS HANDED TO THEM BY THE HEAVY HITTERS AND LORD BACCUS IF YOU WANT A RING GO TO SOUTH PADRE AND EARN ONE... CHEF

Hey guys, I have been talking to a member on here about some calculations I used from BCAE1.com, and something just isnt adding up right.. here is a pic of the box I HAD DESIGNED by a member, so I trust this will work, but I just wanted to enter in the info on BCAE1 to see if they would give me about the same specs.. NOPE....>>>>>>>> This is the box I want to build... but when I put the specs into the BCAE1 site... it tells me to build a 1.3" port... what am I doing wrong here with this program????????? Height? =15 Inches Width? = 39.5 Inches Depth1? =26.5 Inches Depth2? = 26.5 Inches If the above dimensions are OUTSIDE dimensio…

i have 3 300amp breakers now... im popin one of them somtimes.. the onw between my amp and my rear cells,.. i know that once thay pop thay pop easyer... i bought a new one on ebay... i was stoned and bought another 300 amp!..... so now im looking for a 350 amp or a 400 amp CIRCUIT BREAKER... any ideas?

Anyone know if there are any major/non major SPL competitions in NJ area. I would like to go up and watch and maybe participate in the future. But mostly just watch in awe. Curt

I think i wanna run a buss bar only across the ground terminals of 3 batts in the rear of my vehicle. I can't safely run one for both power and ground if you are wondering. Anyway, the reason why i would want to run one for ground is so i can just run all 3 of my amps ground out to the batt's ground buss bar. This way i can run multi runs of ground wires off of the buss bar, let's say 2 runs of 1/0 off the left and 2 runs of 1/0 off the right. Where exactly do i go to get one and how do i know if it's thick enough... if it'll fit on my batts, etc... they are for kinetiks so i know i can take the posts out of the batt to bolt it back down. I found a site that was selling a…

Getting ready to do a little sound deadening this weekend. This is going into an 07 Altima. Do I need to remove any factory deadener that is glued to the floorboard or any other place. I'm not talking about any jute carpet or material that can be easily removed with my hands. I know that some cars have factory carpet/rubber like padding on the floorboards, does this need to get removed or can I just deaden around it? Thanks. Thanks!!! :drink40:

just wanted to get some thoughts on bass box 6 pro..is it user friendly for a noob box builder like me and if so does n e one have it avail for a small fee
