SPL & SQ / Fabrication

Im thinking of wallin my truck (2000 gmc Sierra ext cab) and dropping another death penalty in there. But I have some questions. What is the best side for the body or dead center? Also would the area around it have to be completely sealed or can there be gaps along the sides behind a beauty panel? Do I double the port area? And will this affect sound quality?

Alright, so I'm planning a build for my S10 reg cab, and need help designing the box. It's going to be 2 SA-10's in a 2 cu. ft box net, ported, tuned to 33-35 Hz. Also powered by a SAZ-1500. My max dimensions are 50"L, 22"H, 9"D bottom, 5"D top. I made up a box using the torres box calculator, but I was having problems with the port. I'm planning on using aeroports, but they were needing to be too long for that tuning in a small box. Not sure what diameter, and how many I would need. If anyone can help me out I'd appreciate it!

ok heres the deal. i my box is sub and port same direction as of now i have them firing port up sub up. and there is around 4 inchs space before the trunk lid, and i am scoring a 148. i think i maybe able to squeeze the box in sub back port back.. but i will only have 2 or 3 inchs between the subs and port and wall of my trunk. if i change it up now.. and lose my score then im fucked for this weekend. i have talked with another town car SPL guy. and he stated, in all his testing center port back. he lost 3 DB. from having port on one side, and lost .5 db's on the dash (meca) with sub up port up i guess my short question is.. and at this point its just a g…

I'm wanting to get some feedback/advice on this box I'm working on for my recent purchase from SSA. Any glaring problems in the design? It will fill the area between the back seat and hatch in an '05 Scion xB. Three 10" SSA DCON S4 subs wired to 1.34 ohm Amp: Audiopipe APSM-1300 (1000w @ 1 ohm) - will be replaced eventually, when funds allow Gross volume: 3.95 ft^3 Net volume: 3.3 ft^3 Port Dimensions: 3.75" x 11" x 27.6" Port area: 41.25 in^2 Desired tuning: 32Hz Would it be better to make the box taller and use a square port with more port area, and longer, in the same location?

I ordered two 12" D1 Icons and want to build a box for them before they get here, but I have only built one box before and have had three pre-fab box's before. In all of my sub setups (total of 4) it seemed that my very first enclosure "folded horn" box which is what the salesman told me it was. . Was it actually a folded horn box, I have no idea, BUT according to everyone else apparently you could hear me about 5 blocks away with two 10" memphis subs 250rms each. That box seemed the cleanest i've ever had and it had the port in the middle of the box with a wall in the middle of the port running parallel with it, so basically each subwoofer had its own chamber. My questi…

hey guys, i know i have a thread already about this topic, but that was for my ranger. i now have a 2002 f150 ext. cab and my zcon is on its way so i want to start building a box. i took some measurements tonight and i have up to 6 cubes to play with here. i want ported obviously tuned to aorund 34Hz? i love my lows deep and loud haha. i will have it getting 2300 watts from my aq3500 and yes i have the electrical to back it up with no problem. now, how many cubes do you guys suggest i should go for with this kind of power, and the tuning i want? i will have the sub and port up unless told otherwise. let me know what you guys think!!

Im gonna make a box for a buddy of mine and he wants it to be 8cu ft and tuned to 34hz...i was wondering the size of the aeroport i need...lenth, and what size pipe should i do

Does anyone have experience with sub tunnels(diamond,hexagon, octagon) or manifold style boxes? I was wondering how they are for spl at low frequencies 25 to 30 hz(compared to a straight wall)?

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 know birch is lighter, less dust. but is there any thing that makes it better then mdf? the guy building my box is pushing me to do birch only charging me 50 bucks extra for it so its not breaking the bank or anything. does it sound better? im sure it will last longer. its for a daily system not after numbers i only meter when i get new stuff to see how much of a difference it made. edit: for bad spelling

I plan on going with 3 -10's box will be 3.2cf after sub displacement will be using 2-3 6" external aero ports. Tuned to 32hz and running 2k. Subs in mind are sa's or skar 10's maybe even custom built 10's from splaudio. Box will be subs back port to the front.

hello hello. ive just built box for (2) Nightshade 15's, its tuned at 33 hz and really gets down.. im trying to brace my box and dont wanna take a chance of screwing up my tuning and overall eclosure. my box measures 49x24x20. with a port opening of 18.5hx8.5t. i guess im seeking advice on placement and what exatly would be the best to use. my face is doubled and my overall box is 1.25 thick.

Okay so I am new to this. I am going to be building this in the near future and the hard part is that it's for a regular cab short box s-10 pickup. I do not know if i should go with a "blowout or just put a topor on the truck and put the sub in the back under that. My plan is to run a 2 F.I B.T.L 15" To a Audio Que 3500 H.D Running 1 ohm Power @ 18V** @ 10% THD 7500W x 1. I am trying to find a descent sub box to make up for this. And i have a couple ?'s Like i said i am new to this so am i going to need to push some more power to these beast's or is this going to be enough i mean i want something that is going to wake you up not put you to sleep. Am i going to have to d…

Just need a little help with my box. Running 2 15" Lanzars http://www.lanzar.com/itempage.asp?MODEL=MAXP154D This is the box I've drawn up. Driving a 2004 Ford Taurus. Not very good with boxes. Can anyone come up with a better design?.. Max dimensions 36L x 18H x 20W I'm not sure about "tuning" to certain hz but I would like to hit LOWWW bass please Current Design:

To burp a sub would I just go wth a bigger amp and turn the gain up and give it a burst for 5 seconds or so?

i will be running 4 skar 10's, the box will be in an extended cab dodge dakota, the rough dimensions of the box will be 48" wide, 26" tall, and 15" deep, subs will be on top. now i know if the subs were on the front pannel i would double baffle because of the amount of surface area there is on that panel, but if the panel the subs are on is only 48"x15" would i really need a double baffle? i mean of course i will brace is with allthread or wooden dowels, but i dont want to double baffle if i dont need to, mainly becase that would require me buying an additional 4x8 sheet of mdf.

Would anyone like to help me design a box? please and thank you! here's all the info i can share so far, until i can get some measurements. 16" depth x 24" tall x 48" wide 2 12" d1 xcon's sundown 3000d ported anywhere from 28-33hz this will be my first dual sub setup and i have no idea where to start. i'd like to keep the box 5cu ft or smaller (if possible) thanks in advanced and hopefully tomorrow or the next few days, i can get some solid measurements to work with.

Hey all.I just got a 2007 dodge caliber and im wanting to get a system in it.I have my max deminsions that I wuld like to use.They are 38W x 23H x 11D .My question is what would be the best route to go?Im wanting like 4 10's, specifically FI BL 10's.but not sure if I have enough rooms for them.So would I have enough room or would I need to go a different route? OH and I would have the subs and port facing the hatch.Thanks and let me know if this would work or if I need to go a different way.

I've been searching on here and the internet about port area. I've seen anywhere from 12"/sqft to 25"/sqft. Some say a smaller PAF will act more like a sealed enclosure and tighter sounding with higher power handling. A larger PAF will act more free air with a higher output at lower frequency but will sound loose and lower power handling. I thought the box had more effect than port area does. Where I'm at now. I have a single v1 sa8 in .63 net tuned at 37hz with 17"/sqft. I'm running a sax1200 at 2ohm gained down to 600wrms (clamped). I like the sound but seems that the output is a little lower than I expected. I really have my eye on the new v2 sa8 and would like t…

Would a box that is 2.046 cubes after all displacements with 2 ports that are 1.875x8x22" (will be behind my back seat in my truck) be ok or sound good or give me fair spl numbers with 3 or 4 sa-8s v1 d2s or 3 or 4 orphan 8s in it running off a crescendo bc2000? Is it enough port area? Box volume? Is there anything I should change?

Like the title says, im building a new speakerbag. The fun of causing mischief at the mall and walmart n stuff has disappeared, I want this one for something easily movable, for bragging rights, but mostly as my room system. The backpack aspect makes it more fun =) I am purchasing 12 bazooka OEM 5" subwoofer/midbass drivers, and three 20wrms x2ch Class T amps. I have my two previous batteries (12v Motorcyle battery, 12.5v modem battery) to power the amps, they run on 12v. I have four 5.25" mid/highs speakers already, and will add foam baffles to finish those off If i can work them in. I'm thinking (8) 5's isobaric, sealed, w/ polyfill, in .5cuft. I'm not really looking f…

Hey guys I just recently got two SA 8s and I am getting ready for a custom enclosure. I have been thinking about maybe upfiring them into the rear deck of my new Infiniti M35x and cutting holes for the port and woofers. The only issue is that I did this with some Image Dynamic 8s and wasn't thrilled about the how they sounded. Certain people say that give you a cleaner sound any input? I was also thinking about doing something funky like firing port backwards and subs up like you would in an SUV to see if that made a difference in the trunk. Should I just stick with the conventional trunk box? I was also wondering what people were running for box size (i heard .6 per sub …

Current setup for my 15" Xcon: Sealed enclosure with dimensions - H: 17" W: 32" D: 15" Total space I have is: So I want to do sub up, port side firing w/ aero ... Does this looks good in Torres' calculator???:

Hey guys I have a couple questions. I did a build on 2- SA-12" V.2 Nightshade and I had a custom box built that is 3.0 cf box w/ a port face that is 40x1.2" and is 23" long (specs I got from SA). The subs are firing up and the port is firing back at the bottom of the box. This roughly give me 48 inches of port tuned at 36 hrz, I heard from SA tech that I needed 15 inches of port for each SQ FT. It sounds great, the only problem is it doesn't sound as loud as my ProBox super bass box did. Any suggestions? I talked with SA tech again and they said raise the tuning frequency by cutting off a little off of the port. I checked with ProBox and the Super Bass Boxes are tuned at …
