SPL & SQ / Fabrication

Hello all. I was hoping to get some advice from the SSA community. I have a 2009 Sierra Ext Cab. Currently for substage i am running a 18" Zcon and AQ2200d. The box is 6.6cu ft. net @ 28hz. with 112sq in port area. Sub is firing forward behind drivers seat, port is up. The whole truck has been deadened other than the roof (not too much flex). Pics can be seen im my build thread. Since the pics i have added the AQ2200d and changed the tuning from 34hz to 28hz with a port extension. (the port now fires up from the top front instead of the top back) Changing the tuning really helped with my lows but its still not quite where i want it to be volume wise. Some songs that slamm…

After comparing torres to the RE calc, I realized that it was off (re) by a lot more than I had expected. About an entire cubic foot off. So I think now would be a good time to build a new box. The main question I have is in reference to the "Port Top/Bottom" measurement, I'm not sure where the 4.50" comes from? I'm also not quite sure about how a slot port with no bend's would act since I don't think i've seen many people build one without bends. Main goal is to have the Hifonics brz15 laying face up and the port facing either the trunk or in the cabin, and to be removable (the box). Are there any real advantages to an inward facing port? I've heard that you would want y…

Want to build a series-tunes 6th order for a Single Fi Car Audio SSD 18. Not sure where to start I know 6th orders are more complex to design and more of a trial and error build but if I never try it out I will never learn. So of course the goal is to successfully build a 6th order but depending on the final results if it does not meet expectations there will be adjustments. Also if non of the revisions succeed I will fall back on a standard Ported Enclosure . Please if you have any useful information on 6th order designing/building It would be awesome if you can share them with me . Thanks in advancez max dimension - height 30” - depth 21” - width 38…

hello all! I have a 99 single cab Silverado. I'm wanting to put my 15" BTL N2 in the truck but i've never done a blow through. my concerns are how big to cut the hole out through the cab, should I make it as big as the box? or can I get away with having a smaller hole (only a few inches smaller) I have another BTL that needs to be reconed but, I don't have a amp that can push them both. so for now I want to just put this one in. would a 4th order be a good design or just a slot ported box work better (I'm not a fan of aero ports)

I recently got a great custom box by Audibel Customs for free but I was thinking about building my own fiberglass/mdf enclosure. The only reason I went with Audibel Customs was for the free enclosure if not I would have gotten the Mach5 IXL's. But the Custom box Quentin built is great and hits hard. I just need more space. What I plan on doing is making everthing mdf except for the base/feet of the box. The reason is because my truck has a lot of bumps/curves on the bottom behind the seats and I can gain some airspace in order to do 2 SSA Icon 10's in the future once money comes. I have learned/researched alot of other build logs on fiberglassing and think I have the capa…

Lets see em guys. I wanna know how you guys cram bass into these small areas. Post pics of your single cab setups: amps, speakers, whatever...

*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.

hey all i just got metered at the florida spl/ db drag event in clear water and managed to hit a 133.6 on the TL with an fi x 12 and 350 watts. ooo and everyone should really experience mp3 pimps car first hand it is REDICULOUS!!!!!

Wrong section, sorry.

Pic of specs (or really close to, but hows the design, first ever, opinons, ideas, positive feeback.... will it work?? lol thanks guys!!

I want to have a smaller sub for when I travel or haul things. I currently have a 4 cu ft box with an re sx15 firing up and port back. It doesn't leave me much storage room in the back. Since I can't stack anything on top of the box, or by the port. So I'm thinking about a downfiring rear firing box for one Skar vvx12. It would be on the drivers side. Aprox 14" wide, 13" tall, and 27" long, with 4-5" feet on the bottom. The port would be about 4" off my hatch. I'm thinking about a slot port 2" high and 12.5" wide. Net volume 1.7 tuned to 32 hz. This is for daily listening at reasonable volumes. I'm looking for a 5-600 watt amp to run it off of. How much room should I ha…

I was wondering if anyone would be able to make a sketchup for this box. and please correct me if my tuning is off. box is 4.33384 after sub displacement. W. 30 H. 20.5 D. 16 wood thickness .75 and the port being 32.5in long tuned to 32 hz with a kerfed radius of 3.

I need to build a slanted box and obviously the port is going to need bending. Should I go with a labyrinth port or an l-shaped port ? How do I calculate the lenght of the port, because the top part of it is going to be shorter than the bottom. Should I average the lengths ? A couple pictures might help... To my understanding that would be an overall length of ~40cm. Am I right or am I terribly wrong ?

wondering if anyone else is going to do SLAP this year, I am not sure because there are not that many shows near me, and I am tight on money to build for competition

Wanted to get a few opinions on what you think is better for a spl box, slot port or areo ports?

I am looking to do 1.5 ft3 with a slot port. I am thinking 20x14.25x12.5 with a .5 wide port by 9.8 inch. For the slot is it as easy as it seems just make 13.75 x 9.8 and keep it a half inch off the side wall?

im building a box for a Pioneer TS-W1207D4: 1.65 cu ft 3"x5.5'' port displacement: 0.076 the box ive built is about 1.9ft^3 without any displacements. i'm assuming the 3"x5.5" is the port area and i just need to calculate the length? if so, how long do i need the port for ~35-38hz?

Hello everyone. I am redesigning my enclosure for my 15" ethos for different mounting options. When I use the Torres calculator I am using the total net feature with 3 cu ft and also 3 common walls since it is a slot port. Using a port that is 4x18.5 at 56" long gives me a tuning of 31.94 hz and 74 in2 of port. Then when I use the same size port in the carstereo.com calculator it tells me 48.5" of length is required to give me 32hz tuning. So my question is which one should I use. In sketch up I am designing the port by measuring down the center. Thank you in advance for the help.

What are the pros and cons of the 2? I have a box design for my 8 12's with a slot port but i have heard aeros are solid as well? some1 shed some light on this ^^^ original design

Is the opening of a slot port supposed to be on the face of the enclosure, same direction as the sub is facing? All the boxes I have seen have them there...is that the requirement, or, just common way to build it?

I looked at a couple of websites but am still confused as to how to tune the port to the frequency you want. And how does the length, width, height of the port affect the tuning?

i know ive been asking a lot of questions but ive finally decided on all my equipment the only thing left is getting the box right. it will be a 12" type r fifth gen on an audioque 1200. ive built aero port boxes before but never a slot port. ive always done it with a single sub setup having the sub behind the passenget seat and the aero port out the side on the driver side. the box will be around 1.75^3 to 2.0. im just wondering the best box to get full potential out of the setup

what is the difference between the two? sub would be a 12" FI BL in a 2.5 CuFt box with about 1200 watts. would i save room with the round port? i forgot the tuning, 33Hz
