SPL & SQ / Fabrication

I did search 'box carpet',and you'd be amazed (sarcasm) how much those two words are used on this forum. lol, i went through about 15 pages and found some good info on where to get it,but i still have one question. A lot of people said they got their carpet from a hobby store,and i'm just curious what kind of carpet to look for when i get there. I could be wrong, but i don't see them having "sub enclosure carpet", so i really just need a name to call it... If i can't find it at a hobby store, i guess partsexpress.com is the next choice ($5.85/yd... much better than crutchfield's $30 for 3yds.)

Putting this into a grand caravan, middle seats up, backseat stowed. Going ported, thinking 30-33hz tuning wise, any recommendations? Going to run it off a Sundown 1500d, so box size recommendations? Also, will be running the stock alt for awhile (160 factory). Doing my big 3 upgrade with 1/0 and a single run of 1/0 for now....later upgrades will be wiring and alt before anything else...also no sound deadening for now...also looking for any recommendations for sub/port orientation? sub/port back towards hatch, sub up/ports toward hatch, sub up/port facing side....anyone with experience in a minivan would be nice, not that most of you have one, but a guy can hope lol. than…

So I couldn't sleep last night and decided to start designing the box I want to build for my 4 SA-10s that im getting in next week. Thought I'd post up the pics.... Also, After discussing yesterday with a few of you and trying to decide how to do port area and everything with some aero ports, I decided on the (4) 4" aero ports.. But then after I designed it and everything I realized that the tuning you guys said was about 39hz.... and Sundown recommends 30-35hz for these subs.. 39hz was like the only tuning we could get to work in order to get enough port area for my setup.. So I wanted to make sure before I buy everything and build this,.. Are the subs going to do/sound …

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…

I know this question has been posted before all over, but many of the discussions just turn into b***hfests, and no straight good answer is given. Would stuffing (polyfill etc...), or lining (vibration damper, mlv, etc...) a properly sized and well built box make any difference on the sound quality/characteristics of the subwoofer it contains? I'm looking for one good answer please, not a million random opinions. My head is just in a daze after looking at how many odd forum posts that don't answer the question I'm posing. Thanks to anyone who has good knowledge on this topic!

Why do you compete? Since I opened, I will let you all know why I compete. I compete to have fun and to represent. One of the main reasons why I compete is because of the gear I run. Back when i started, it was about fun and there were plenty of Orion competitors, now there is a few of us, and I doubt that none are as serious as I with the Orion equipment. That would be the main reason, to bring back the Orion name to the competition arena, make them the proud people they used to be. Many of you might not remember Orion back in the days when Wayne Harris used to work for them, or when you could see atleast 40 cars at finals with their equipment. Not only am I bringi…

Memphis doesn't carry them in their site. Did some searching but only came up with the subs or some other t/s parameters . I doubt the place that sells them here will give them up cause they make boxes. They are kinda like that. They gave me recommended optimal. The port however doesn't make sense. I used Torres calc. To do their recommended port size. It's way too small IMO. 4ft^3 for two 12's with a port of 12x2.5x19long which tunes it to 28hz. I wanted to get what the actual T/S parameters are so I can get an accurate idea of how to build it.

i'm getting ready to wall of my car @ the b-pillar, w/ a series tuned 6th order bandpass for my 2 15's i'm hoping to be in the 150's w/ this setup. here is the plan for my wall, and a pic of the old setup.....(except i'm running soundstream dbx 15's, not the RL-p's) what do you think???

hey guys...just wondering what u guys would recommend to use or have used to keep your box from sliding around? i have a trunk car so mine just moves all over the place...? velcro? l-shaped metal corner brackets? open to ideas...

I am looking for a box design for 3 audioque HDC3 10's my trunk specs H 16 in L 43 in W 36 in the mouth of my trunk is 44in looking for a 4.5 cuft box tuned to 36/37 hertz i don't know how much port area though,

Hey guys, my friend has a Ford Ranger and he asked me if having the port facing the door or roof would be louder. And I decided to ask on here for him. Reason because he is getting a box designed, what would the pros/cons of having it facing either way be? Thanks in advance.

Well, I'm adding 2 more DP21"s to my Expedition in a month or two. I was planning on doing a clam wall at the B-pillars. But I also started thinking doing a diamond type enclosure would be pretty sweet too. So I'm looking for some opinions on what you think would be louder, first and foremost, and look better. Which ever design I go with will be at the B-pillars, between 35 and 40 cubes, tuned to 32hz. Please explain why you voted the way you did. I have never done either of these designs, so any tips are also appreciated. The subs.

sorry if this is in the wrong place, i wasnt really sure where to put it. move if needed. i just know lots of RE questions get asked so i'd thought i'd start it here. i posted the same thing on caraudio forum and thought i might as well post it here too. if anyone has any ideas i am open for anything. -getting around on a build for an 18 inch 2005 xxx. ive done some searching on box sizes and such for this and i am thinking... 8 cubes 34 hz 115 inches of port do those numbers sound about right? bigger box? more port? this is going in a 97 grand marquis...huge effing trunk...FTW amp is a saz1500 i was also porting the rear deck and taking out the back deck speakers. was t…

sup planning on entering in my first spl comp. in Roanoke Va. Mar.22. Was reading the rules and got somewhat stuck on the part about the fuse requirements. I'm using a 200amp circuit breaker, do i need to install a fuse in its place to enter. Will be running a saz-1500d on 2 12" lvl4 d1, also would be considered AS1 or AS2. Hope to meet some of you there. Styllikeitloud

currently running a sundown saz1500 powering a fully loaded 12in fi bl in a 2.5 cu ft box tuned to 34 hz. I was recently at a local audio shop and had the main guy set my gains properly so i did no have any clipping. I was not very impressed with the outcome. As i come to find i had been running with clipping since day one and my system is now quieter. He told me to tune my box to 40-42hz and it would be louder. My question is how much louder? and will i still be able to play most rap music? What would be the lowest tone i could safely play?

willl be running a rockford fosgate t1500 on a 15" xcon listening to all sorts of music sq over spl but i still wanna move a lil bit of hair if it makes a difference does it make a big difference if the sub is up port back vs both up or both back? its going in a 98 Honda CRV....simular to the picture bellow, id post mine but im having a hard time figuring it out.

Sorry for the long post. I just bought a pair of Beals Bros 8" midbass drivers. I have no specs on them. I know you are probably saying to yourself, why would he buy them if he doesnt know anything about them. Well they were cheap and in great shape. Now on the the questions. As many of you know I am currently running a set of CDT HD-62 pushed by a Memphis 16-mc300 ~150x2@4ohm (depending on voltage) ~240x2@2ohm ( " " " ) Here is where the questions start. The Beals is 2 ohm nominal and the HDs are 4ohm. that would make the final load 6ohm for series ( not enough) or 1.3ohm for parallel ( too low). I have heard that lower impedance=more distorti…
