SPL & SQ / Fabrication

I am looking to get a 15"or 18" to go into a sealed box for sq. Leaning towards the 15" at the moment. Car: 98 Mustang Location: Trunk Amp: MTX te1501d (birthsheet @ 1 ohm is 1556 rms @ 13.8 volts) Wires: 0 gauge on big 3, main battery to second battery in trunk, & from second battery to sub amp. 4 gauge to highs/mid amp from second battery. Stock 130a alt. but I'm getting a 270 Mechman and xs 3100d( will be under rear seat) when i order the sub or shortly after. If i go with the 15 the box will be 26.5L x 26.5D x 11H about 3.5 cubes before displacement. Sub will be upward firing. I'm tossing up the idea of the 18" but don't have experience with 18's. Any idea's if t…

Is it possible to to a T shaped slot port? I'm designing a box right now with 2 woofers and no divider. I was planning on making a L shaped slot port off to one side of the woofers, but got to thinking about putting the port in between the woofers and making it shaped like a T without a divider in the middle. No clue if this would work or if the velocity of the air coming from each side would create turbulence where they meet and make the port less efficient. I would put a divider in but I'm limited on space and a divider makes the port length longer per side and cause me to increase the size of the box to stay optimum and the dimensions are larger than I have to work wit…

Lately I've been pretty frustrated with my sub stage in my vehicle. I am not any kind of box designer but I can and have built my own from others blueprints. I've always helped my friend with systems in his 08 Grand Prix. I have installed a lot of my enclosures in his vehicle with good results. Then I put the same boxes in my vehicle and get something totally different. Every vehicle is different I understand this. We both have trunk cars. Mine is an 11' Malibu. He clearly has a slightly bigger trunk than I do. What I'm looking for is a better low end. The boxes I've used have all been tuned around 30-32ish. What do I need to take into consideration to build a box to ex…

I got a cut sheet from skar audio, and i want to know others opinions on it. Ive tried to draw it up on paper to visualize, and ive done some calculations to help someone who knows how to use the info. Its for a friend so i don't wanna waste his cash on a shit design. Ok so he has a 97 Jeep grand cherokee. 90a alternator, I did the big 3 for him in some 4 gauge stinger pro i had laying around, and he had already bought a Rockford amp kit 4 gauge also...pretty nice wire. Ok the max dims are 36" wide, 36"deep and 30"tall, this leaves plenty space for the port to breath either up our back..The subwoofer is a skar audio ivx15 V1. Its a d2 coil. Here's spec off woofersetc.co…

So ive currently have got an Fi SSD15 in a 3 cube box, ported tuned around 31 hz. it murders the lows, and theres no port noise that i can tell despite it having only about 11 sq inches per cubic foot of box volume. the problem is, there seems to be cancellation in the 50-65hz range. it hits great below that and even gets louder over 65hz until it starts rolling off around 85hz. this is in the trunk of a 2001 BMW 525i. i have the sub fired up with the port back. im very frustrated with this lack of a crucial sub bass octave. i'm about to build a new box, in the neighborhood of 4 cubes with a port tuned around 35 hz, with at least 14 sq inches per cubic foot of interna…

Ok I have a few questions about the closure that I am designing. First is this a slot port design? Second do i need to throw some bracing in the inclosure or is it good as is? Third Have used various calculators to calculate port size for tuning is this correct? The box I have designed is 20"L x 48"W x 15"H puting the box at 5.3 without bracing. The subs will be facing the rear door and the port will be facing up on the back wall. Port will be 4"H x 20"W x 22.21"L. The port Vol is 1776.8 the port area is 80" square. Any and all help with this will be great Vehicle : 1999 Chevy Tahoe Location in the vehicle: Rear Space available (Length x Width x Height): (x)…

IM abiut to dig in and start my own center console here in the next few days. Any tips and things to look out for? I want to incorporate this touch panel that ive been working on...also some clean plexi....my tablet and possibly an armrest/compartment for random stuff. Ive seen some awesome stuff on Google....shoot me some info. Thanks!!!

Can anyone design me a box for two 15 inch subwoofers? Two 15 inch SHOK minis. I can go 16 inches tall, 36 inches wide and 18 inches deep. These right here. Thanks in advanced.

I have been looking in to these two subs for months now reading everything I can. I am still stuck maybe some smart people can help me out. ok I am looking for high quality, clarity, accurate, punchy sound not so much loud. mainly SQ. I had two Pioneer TS-W309D4 in a sealed box at 1.15 Cu. Ft. Air Space per sub. powered by a Pyle PLA2678. I liked this sound it sounded nice punchy. but I wanted something better so this guy told me about FI and Audio Pipe amps . so then I got a FI SSD 12 with only interior leads. powered by a AUDIOPIPE APSM-1500 and in 2cu ft. of air space. tuned to 32hz ported. it got so loud my nose flap would shake and it was awesome and still …

My 15 will be here today, and ive spent the last week drawing up designs but before i commit to any, does anyone have a more accurate box calc than Re.com? My friend used it and his came out nearly a 1/4 cubic foot bigger and tuned like 4~hz higher than what re box calc told him.

Hope this image works. Its a very rough sketch of what I'm planning. It's roughly 2.5 cu. ft after port and before sub volume is removed. Subs firing down, port forward. This is roughly the outside dimensions I have to work with and am open to other sub/port configurations if they make sense. Subs will likely be SA-10s or maybe Gcon 10s. Torres calculator showed 32 hz tuning frequency, but I'm confused why it asks for a port diameter and port dimensions for a slot port?? Any opinions?

Hello world, after much research and consideration I have finally decided to become an SSA consumer, I plan on buying a DCON series 15in to run with an Alpine MRP-M650. I plan on designing and building a custom ported enclosure for the sub, and this yields the question, what is the recommended volume for said enclosure? I know the SSA Store gives recommended box dimensions, and I have seen them for the DCON 12, but the fields are empty for the 15 D: Any help is appreciated. My guess would be somewhere around 3-4 cubes? But it's my first build so I feel like I need some reassurance. Thanks

There are 2 drivers in each side wall that would acoustically, i assume, act as port length. So, if that's true, does leaving just the opening in the back act as length of the side walls which is ~25" long? also, i've never had the time to question these types of designs but does anyone have anything negative to say about drivers in the side wall like that? I've seen pretty much all different kinds of setups throughout the years and this particular one is not new either. I just don't understand what actually is going on when the front wave of these side wall drivers interacts with the port(2nd question).

how many sheets of mdf would i need for a 4.25 to 4.5 cu ft box for two 12's and 2 cu ft per chamber and a 30hz tune going to build a box tomorrow so please let me know asap

*hint hint My buddy is looking to build a center console box for an IA Lethal Injection 15. Looking at 3.5 cu ft ~50 inches of port and tuned to 32 Hz. Looking for suggestions and possible cut sheet. Going into a single cab dodge. From the back wall to as far forward as possible without losing cup holder is 48", between the seats is 14.75" and we're hoping to stay as low as possible for a custom arm-rest. Is this possible? How should he mount the sub? Trying to get as much SPL as he can for daily music listening. Driver displacement is 0.15 cu ft. I'd appreciate the help guys.

So I'm good at building enclosures.....calculating ported enclosures? Not so much. I've just bought a new tow vehicle and using some budget equipment to put a nice setup in it. These are new items I've had laying around to put into a project car I'm building that won't be finished for a while.

As title says, there's a few shops here but nothing I trust..... I want a box built and designed around my cars cabin gain... Not a box just built to specs

not sure if I should post here or the head unit processing forum so sorry if the wrong place I did a forum search with the word active with no real results I am going to be purchasing a 80prs by pioneer here pretty soon and am very intrigued on what exactly active is does anyone have any good quality sites you could link me to with good information not common rumors or otherwise so I can begin my journey of discovery I don't mean to try and be spoon fed but we all know google isn't the most credible source so I would like to get credible sources from the experts first then after I research those and learn something then I will probably come back to this thread and pick yo…

So I've had the car a year, and after a spring break trip to Florida, I found out that it's cramped with three passengers and luggage for a week. My brother should be getting a car within two years and he wants the current set up, so I'm getting a head start on my planning LOL, ready to pull the trigger when I get the money to do so. I built my own floor for the extra battery and some storage space. The sub box currently fits across the whole trunk from the back to the break in those side pieces. I want to put together two separate boxes, each to house either an SA-8 or an SD-8, sub facing back. I still want to keep access to my spare, so the cover I made for it …

Hey guys. i just purchased a 15" Fi.BL sub and before it gets to my house i was hoping to get a box design built.

From what I have read here the port area per square foot rule is just a myth, port area has nothing to do with the size of the box. I tried searching more and all I could find was that port area is determined by the parameters of the sub, tuning, and amount of power. So I am curious what formula is used to actually calculate how much port area you need? I am currently designing a new enclosure for my 15" Fi SP4 which is run off an AQ3500. My old box was designed to fit in a trunk but now I have a Tahoe so size is not as big of a restriction for the new box. It was 3.83cuFt @32.25Hz (after displacement). I like the low end but actually would like to try tuning lower. I …

Im designing a box for my new improved build and i jus want to verify that im doing it all correctly. The box will be for two 15 inch SSA EVIL series subs. But for right now i have two dc lvl 4 15's that will go into the box temporarily. So it will be designed mainly around the EVIL's. The car its going into is a 2007 Scion Tc. I measured out max dimensions and came up with a box that i think turned out very well. i wanted it tuned low, mid 30's and low 31's maybe. Heres what i came up with::: Pic from sketchup (Copied and pasted from MS word) Box Measurements Maximum limits for the SCION TC Width = 37 inch max (pushing) …
