SPL & SQ / Fabrication

Only one sub rite now the other one will be in on Tuesday. Box is 7.1 cubes tuned @ 30hz Hit 144.4 sealed up at 43hz without much testing. 146.7 outlaw.

Hey all, newb here! I just ordered a 12" BTL, so I have about 3 weeks to plan my build, with the biggest project being the box. I heard a while ago that in an SUV, a setup in which the subwoofer is pointing up, and the port is pointing back is optimal (straight from Memphis Audio), but yesterday I found a page showing tests that the subwoofer pointing back yielded higher SPL levels versus the same sub pointing up or even to the side. Which is correct? Does anyone have any personal experience with SUVs that can shed some light for me? I will probably be building the box to Fi's cut sheet dimensions, just need to know whether to put the sub on top, with the port facing…

is the DD9112,AQ LW12,or Eclipse Titanium SW9122 better for SQ?

Picked up 4 havoc 15's for my ext cab f150. Problem I have is my max width in the back is 58.5" and I want to fire up so I can't do a straight baffle and have enough surface area. I need to do an angled baffle and have come up with two ideas but wanted to throw it out to see if anybody had a preference between the two or maybe other suggestions. Max dimensions are roughly 25h x 23.5d x 58.5 long These will be sealed:

For Starters it will be going in a 2004 Chevy Tahoe. My demensions i would like to stay in are:30Dx47Wx27H. Box will be for 2 18 inch DSS Ethos powered by a Soundqubed 3500.1 5cft net for each sub tuned to 32 hertz. I wanna do Subs Up Port back and havent decided if i want to go with aeros or a traditional slot port design. Which would be easier for a first time box builder? Included some photos of "my hoe". Thanks in advance for the help guys!!!!

I am using CAD right now to try to make a 3d design of my box. My question is if it is an 8 cu ft. box before displacement with external aeroports, what kind of internal bracing am I going to need even with a double baffle? This is getting a fully loaded 18" BTL by the way, with a Sundown 3000d. If I use 3/4" MDF will I have a problem with too much flexing? Also one question this is my first build, first system and I want to know what your guys preference is on MDF from different suppliers. All I really have around here is a Menards and I work there so I can get a small discount on it there. I just wondered what you guys think of the quality of Menard's MDF compared to ot…

I have an old sub box that came with an RE SX15 I bought used. It is 3.1 cu ft net before driver displacement. It has 2-3" aero ports in it. 9" long. I used it before with the sx15 wired at 2 ohms on my saz-1500d. I never heard any port noise, but it didn't sound great. I later built a 4.25 net cu ft box for the RE tuned to 30 hz. It sounds great. Well I think I have a buyer for the RE and was wondering if an SA15 would work in the old box. It's about the right volume and tuning would be right about 35hz(recommended) but it's seriously low on port volume. I was also thinking I could put a third port in it for burps and bump tuning from 35-45hz. Not to mention increasing …

Can someone help me out with some dimensions for a sealed box for 2 Icon 12's? Need 1.25 cu ft. per speaker. Going in an Escalade. Have 46.5" width avail. Currently in a badass ported box I built. Want to try out the sealed enclosure for SQ. Attached a pic of my current box.

I decided to finally sack up and start planning a blow through. I just can't find anything around the web that actually explains. I really want to use aero ports. Do you think, if I sent two aero ports through the bed, and into the cab, that would be sufficient? I'd like to cut the smallest holes possible. Although I said before that I sacked up, I'm still pretty scared about cutting up my relatively new truck =). So, anyone have personal experience, pictures, or even tutorials? Thanks OH. Before I forget, My goals are to sound good, but have a really nice side of spl on the side. Just a daily ground pounder that sounds good,. I'm still trying to decide on which subs, bu…

I'd like a box cabinet plan drawn up I don't know if I'm going with this design yet or not, but if I do I'd like to have a plan for it. I'm basically doing a homebrew version of this: http://www.omegaloudspeakers.com/ts33.htm Using these drivers: http://www.madisound.com/pdf/fostexcabs/fe126e_encl.pdf If it models well, I wouldn't mind going with a tower speaker instead of a bookshelf - although I don't know exactly how it would react. Thanks...

Long story short my friend built my box and it turned out horrible it wasent his fault he did not have enough tools or supplies but I'm getting a shop to build me a new one and I have an original design but its to wide but I can add to the height my dimensions are 22 deep 33 high 55 wide the box design is 27 high 27 deep and 54 wide wouldn't the volume even out if I went 32 high and 22 deep?

i would like some idea's please i have about 3.352 cft internal external 40.5"width 10.5"height 18 depth,i wish to use 2 or 3 old usd 1260 subs. speaker paremeter RE 5.24 QTS 0.39 QMS 15.60 FS 12.29 QES 0.40 XMAS 3.708 LE 1.01 Z 8 OMH PE 200 i would like to try and build a transmissione line box. i found this info for building the above box.please can any one help me all help will be gratefuly recieved. below is an example of how to make a transmission line 43.46 / 4 = 10.86 10.86 is the throat length of the enclosure.

i want to thank those of you who pointed out the error of the batterys as projectiles. there in a safe place under the amp rack now... back seat has been removed / replaced with a flipp up amp rack boxx placed for fitt

I am trying to decide whether I want to go sealed or ported. My question is with tuning frequencies. Lets say that a subwoofers optimal tuning frequency is at 33hrtz and someone builty a box for 35hrtz, how would that effect the sound. And also what would the effect be if it was the opposite and designed a box at 27hrtz, how would that effect the sound. Sorry if this question has been asking a bunch before but I couldn't really find the answer I was looking for.

For those with hatchbacks and/or hatchback experience. Folding rear seats, so large enclosures will work. What enclosure has worked best for you? CRX style? Sub up, back, forward, or angled towards glass? Port up, back, forwatd, or angled towards glass? Daily driver. I'm tempted to try something in the Mazda for the uberwoofer. Can be pretty large, so uncommon enclosures can work as well. It'll boil down to having the sub and port firing forward between the seats or any of the above ways.

Ok guys i have a 2006 charger. It supposedly has a 180 amp alt in it. Over the past few weeks i have done everything i could possible think of to get rid of this alt whine. Change grounds on the HU and the AMP.Changed RCA's. Ran an isolated ground to HU from the battery. Gave the HU an isolated power to an external battery. Seperate ground to the alt with the stock wiring in. New alt power wire with the stock wiring as well. Took the serpantine belt off the pully's to see if there was any catching in the alt(no catching nor was there an play in the alt shaft). Went and got the alt tested today its a good alt. Got the battery tested and its a good battery. The only time th…

i blended the sub down to fit in with the front stage and all i can hear is Loose Plastic panels Rattelling... s0o0o0o0o i have spent the last 2 nights re-doing the front doors & the thinggy in the headliner of the explorer... now all the Rattelling is behind me...

There used to be a few threads about things people were doing for SQ competition and some of the things each organization makes you have for max points in each category. I have a few questions about some of those things. I will be building based off of Usaci rules mainly because besides SBN (which offers Iasca as well) they have the most SQ comps in logical distances from me. My first question is about Processors, crossovers and EQ's. Do I need any of those three for max points or if I buy a HU that has all of those things built in will that count? If need be I will buy a cheaper HU and add something like the PPI-DCX730 as opposed to something like the Pioneer 880 or the…

well i am starting the build for 1 zcon 15 tomorrow and i have a few final questions id like to get out the way to make sure this is done right the first time..... 1: should i put 45degree angles in all the corners for better airflow??? here is the link to all the dimensions and everything im doing (thanks Alton!!) Post #11 this is my daily set-up so im not going all out for spl.... i had another question but i cant think of it at the moment... haha im sure ill think of it here shortly so ill post as soon as i do haha thanks guys!!

Alright, so iv been looking at the inside of my car lately and it makes me a bit sad. My car is black on the outside, with a 2 tone grey interior and wood trim pieces. What i was thinking is to get a bit creative and change up the looks of my interior. I wont be upholstering or anything, i was just thinking about taking off some of the pieces and painting them black... Not sure yet... Give me your opinion if youve ever done something like this. Heres a few pictures so you can see what im working with.

Right now I have a 2.2cubes @ 32hz with 34.50sq.in. of port area with 1100rms for my daily driver. I want to build a pure spl box and a pure sq box before the winter comes. I have 34inches in width and 13inches in hieght. I need to know the tunning, port area, and cubes for each enclosure. I heard spl enclosures should be small and have alot of port area. I'm not sure what kind of boxes I should build so i'd figure i'd ask here since noone knows the icon better than you guys, Thankz.

Do any of you know what software 'HexiBase' is using to make his enclosures? https://www.youtube.com/watch?v=5VFx37kz5Ww It would be awesome to have a bit of a play around with it to see how my current system stacks up. Thanks in advance

where is their build house at? who would do the service on the equipment? and where can I find the new COMPx2 for a decent price, I would prefer to run it over the Orion H2 and RE XXX, but the it might be priced to far out there

ok, i did a 143.9 w/ my 2 15's. and i'm wanting to redo the box to try for louder. i'm putting about 750-800 to them a piece. do you think i could get 1 15 w/ 1600w louder than the 2? or would i be better off sticking w/ the 2?
