SPL & SQ / Fabrication

Am trying to calculate the exact cu.ft for a wedge enclosure. I tried a few different sites and got anywhere from 5.8 - 6.0 cu.ft. Since I needed the exact size I worked it out by hand myself. Here are my dimensions and what i got. Can anyone double check this for me please? Wedge Design Outside Dimensions Height = 22" Depth 1 = 10" Depth 2 = 20" Width = 39" Formulas used: Rectangle L X W X D Triangle 0.5 (B X H X W) Since the design is basicly a rectangle and a triangle combination, thats how i calculated it. I got 4.12 cu.ft for the rectangle and 2.06 cu.ft for the triangle with a gross volume of 6.18 cu.ft. I also took into account that the 1.5"…

i just got a lightning audio storm x2.h15. v4 and ive been looking for a new recone does anyone know where i might find a new recone?

i made a box using RE box builder and this is what i cam up with i am putting a 18" night shade in it how much air space do i have and whats it tuned at i think iKnow but wanna double check with you guys first W=36 H= 22 TD= 24 Bd= 24 1"MDF port 1= 6" port 2= 4"

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

i already have a btl 18 in my magnum but am wanting to add another. what im wanting is some ideas on boxes, not sure what my max dimensions are. thanks for any ideas

So i am building a new box as of this moment i have 2.5 net volume without any sub displacement or any thing. The driver is 1 RE SE12 . My desired tuning frequency is around 32-34 hz. I want to know what the port diameter and length i have tried some calculators but they are to long for the enclosure.

I just received a phone call from Matt Borgardt at ID. Due to the fact that he is seriously ill, we will be unable to have the IASCA event on Jan 24th. The event will be rescheduled for some time in April. The next IASCA show will be February 15th at Beach Autosound in Huntington Beach, Ca. I apologize for any inconvenience this may cause any of you. Please try to spread the word so we don't have people driving in from out of town to show up at an empty parking lot. -Todd Woodworth

ok...im gettin a cae this summer...((gas mileage purposes)) and dont know really anything about doin subs in cars....ive done trucks forever and know all about them but im dumb when it comes to what cars sound good with what....so i wanna hear some opinions on what setups yall have going in cars tht put up respectable numbers thnks, zak

What is the best place to find 4" id aero ports that don't flare out past 6.75" maybe 7" that won't break the bank? What would be the best brand for the price? Is it better or easier to use schedule 40 pvc pipe or the tubes you can buy for the flares or get a whole kit? Will any flare fit pvc pipe? Would they work if the port inside the box faced each other about 16" apart, firing in opposite directions? Ps i will have 4 sa-8s in about 2.73 cubes before any displacement with about 500 watts going to each and i do not have enough room to use 6". And i want to have it tuned for daily use, anywhere in between 33-40 hz

I am just dreaming here. I plan to upgrade my substage, but due to a lack of cash, this probably wont be for another year or so. im just kinda tossin around ideas. I want to have a system that is "Clean n Loud", not geared specifically towards SQ or SPL. I listen mainly to rock, metal, but on occasion rap and R&B (so basically everything). I have a decent sized trunk but the entrence to said trunk is very small, hindering what can fit into it..... So far i am thinking of three ideas that would fit. The first would be to run 2 10" SSD's in a ported box, tuned to ~30 hz, the second would be to run 2 12" SSD's in a sealed box. Any recomendations on these two? Like i sa…

ok. i think i might have the box ready to go with all the deminsions. i play on putting 2 sundown nightshade 18s in my truck. i was told it need 12^2-16^2 inches of port area. so the box i came up with is 11.5 cubes, with a a port that is 33 inches tall and 5.5 inches wide, this will give me 181.5^2 inches of port area and i need 184 with the box size. its going to be tuned to 30hz. will this work out to be a good box? or do i need to do something different, just let me know

Need suggestions on bracing for this box. Would a single 4x4 in the center of this box be enough bracing for top to bottom. I haven't added bracing from side to side or front to back yet. Total top width is just over 52 and bottom is just over 41 wide 38 deep and 18 tall designed for 4 12's

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

Since I have a Ford Taurus my trunck was totally sealed and no bass would come through and had to port my seat and my deck lid and am trying to locate some speaker cloth that will let the bass to travel through without affecting airflow. Do they make this. I did try the metal mesh grill like I saw in an Overhualing tv show but found it affected bass intensity and sound quality. I am a musician and know my bassists amp has a plastic type mesh (grill) that suppesedly doesn't affect sound quality. Just wondering if anyone out there uses anything specific?

hey guys, this is probably a noob question, but i have an 18" fi q in my car with the bp option. i have it hooked up to a hifonics 1610 1600watts rms, i am running about 1200 (i set it with a dmm). its in a 6.3 cubic foot box after displacement, and its tuned to 31 hz. my question is, why is it that when my doors are open it sounds alot louder than with the door shut. opening the windows helps when im driving, but its getting cold and i wasnt sure if there was anything i could do to make it loud with the doors and windows shut. any help would b great. thanx.

i wanna use a 6 inch port tube going up in my car from top of box and sub facing back cup holder whole in seat.I no wat size is optimal for the 10 xcon. But how long would the port have to be. I want to tune around 30. My space to use up (32L) (14H) (14D)

Hi, I am getting ready to switch my system from my firebird to my truck, so I can sell the car.. It's going in a 99 s10 ext. cab xtreme.. I have 1 12" pioneer premier 3002d4, It's in a sealed box now, but I want to build a ported one for it. I will be using a precision power 1500 amp at 2 ohms, so roughly 1000 watts to it. I know how to do the wood work, but I am not near as good with calculations.lol. A good slot port box design wood help a lot, if anyone has the time. I would like it to be tuned to 34hz, with 1.7 cu without the sub. For room in the back of the truck I have 14 1/2"x18 1/2"x50".. I know thats more than enough, but thats the total space I have. Also, wh…

I ordered my First 18in. btl on tuesday and i am ordering my second on friday. In anticipation I got to playing around with some designs. I am going with a wall build in my trailblazer and i got the front template all cut out perfectly today and threw it into sketchup. Double baffled 3/4in. mdf on the front and double baffle all around for the actual enclosure also " even though it is not shown in sketchup" After sub displacement it sits at 21.07cf. and no i am not counting the sub braces since i just put those in to see how i would set them since i dont have the actual subs yet. also i will be throwing in a couple of 45's to help so am i missing anything big/gettin…

When mounting subs like this, can you make the enclosure smaller than recommended? For instance, if the subs call for 1.5 cubes each ported can you get away with making the box 2-2.5 for both? What are the (dis)advantages to mounting subs like this? Or are there any?I know the polarity needs to be reversed with the sub mounted inverted.

I am thinking about putting 2 SA-8 in my truck. I have a reg cab 03 S10. I need something small cause of the room issue. The box calculator on the RE Audio site gave me some weird dimensions. Like the port only having .25 inches gap to the back plate with a fz of around 33hz. Does that sound right? Any ideas would be appreciated. Thanks

looking for some info on a spl ported box design for 2 15" dc level 4 or where i may look into getting one built????

the sub should be here within the week. it will be going in a 2002 cavalier. i have limits on the box, so i have come up with 36w x 17h x 13d with 2 3"ID ports tuning to 35hz. i read some where i could tune the box a little higher due to the fact i listen to a wide range of music. any truth?? sub will fire into the cab area. i have also read some where about sealing off the trunk. so, i would seal off the enclosure from the rest of the trunk and channel all the sound into the cab area?? any specifications on space needed in front of the woofer or ports??

I need help with a box spec for my 2 Sundown Audio SA-15s. Its going into a Izusu Rodeo. The box can be up to 41 inches wide. I looking for a box that i can use as a daily driver and for competitions. I would appreciate the help.
