SPL & SQ / Fabrication

I am currently building a new setup and I am torn on how to tune my box. I will be running 2 18" Fi BTL N2's, 2 Hifonics 2600.10's, and 4 XS D2400's. I am posting to get feedback on which setup would be best, going with a spl setup and tune my box around 32-35 Hz, or go with a wave setup and tune my box around 25-28 Hz.? Feedback and oppinions are needed thanks.

Right now, Im running an audioque hdc3 12 in a 2.2 cubic ft box ported at 30 hz. Im losing alot of sound quality with this box and I was wondering if there are any specific box types (other than sealed) in which I may be able to retain a bit more quality. Im aware that the hdc3 is known for poor sound quality but Id rather not purchase a new driver at this time. I know anybody could tell me that it varies from car to car or something general like that but Im just looking for anyone with some experience who may be able to help me out. Open to any suggestions! Thanks

For my next set up I'm thinking of running an active 3 way system. I would like to run an Sax-125.2 or a Sax100.4 whichever is better for a 3 way setup. My budget its slightly fixed anywhere from 200-250 for the 3 way set up. This will be going into a 4 Door Explorer. I typically listen to anything from Rap to death metal to spoken word; I would like a system that is well versed and able to transit from genre to genre with ease. Also to be able to reproduce it accurately but also i need something loud to be behind 4 15's. I am able to fabricate things; i have fiberglassed and know how, also i have access to many tools. I need to start off finding Tweeter, Midrange, and a…

Please help, need enclosure ideas looking to break 150 while still being able to listen to music. I'm running a pioneer premier 3000.1 temporarily but will be changing over to hifonics cyclops. Any ideas would be helpful as i was debating a wall but am not sure what would be best. Have tried so many boxes that i'm tird of killing trees...PLEASE HELP!!! Thanks.

I have noticed that my subs (2 12 inch pioneer champs) are peaking high. I think my tune may be messed up but I just cant get it right. It will get real low and then attempt to hit a few high notes. The amp itself should be tuned with lpf at around 35 and ssf at around 20. Any suggestions?

New JBL W12GTi MKII waiting for a home. Need to do sealed as space is limited but plenty to work with for a proper enclosure. Looking for it to attack the lows and have a flat(ish) response. Not a ground pounder, rather a SQ build for this old man.

I have 4 DP21"s and 2 SAZ-3000d's that I'm stuffing in my 03 Expedition. I'm looking for ways to get enough port area with the subs...The box will be at the B-pillars sealed from the back. It will be about 40 cubes tuned to between 30 and 32 hz. So I'm wandering if I could port through the diamond itself without any problems. Or would this be bad?...Any other ways to get sufficient port area would be appreciated also.

So i was a little bored today and had an hour to kill. I figure, all the equipent I have laying around... I might as well put something in the truck and play around. Dropped in my old CRX-stlye box, pair of RE SX 15"s, and an Orion 2500D. Setup for 2kw before Imp. Rise. Ran a sweep, found the boxes peak with these woofers. Burped a couple of times. Then went back to a sweep to get a good reading before the batt drained too much. Stock Delco batt (3 years old). So far for this season in Street C, this would've put me 6th place. http://www.termpro.com/asp/leaderboard3.asp Not bad for dropping in and not testing anything. -Nick

how exactly do they work?? i see people use them that usually have limited space but i dont understand why or how they are used. also do they sound any different then a regular slot style ported box? i want to do 2 15" lethal injection's but i would like to get a quick insight on aero ports and how they are used and if they sound worse then slot ported.

If you have two boxes at the same volume and say one had a 2" slot port width and the other had a 3.5" port width tuned to the same frequency would there be a difference? Would the 3.5" port allow you to feel the lows better than the 2" port but sound the same since they are tuned the same?

Well I went to my teams shop last weekend and decided I would do a little testing with my new setup. The equipment used is a 21in warden and SAZ 3500. The vehicle is a 97 blazer. Electrical is one yellow top under the hood one extra battery in the back and 2/0 welding cable. Box is a little over 9 cubes and tuned at 40 htz. If any one would like to give feedback on how to get it louder or just comments in general everything helps.

Like I …

I don't want to upset anyone by saying I'm looking for an SQ setup if I'm actually looking for SPL, so I'm hoping someone can steer me in the right direction. I don't like mainstream rap music, and I don't ever plan on getting my setup metered or compete, so big dB numbers arent a concern. I listen to mostly underground hip hop and a little bit of rock, like 80s metallica/slayer, so hardly any of the songs I listen to dip into the really low frequency range. I'm running 2 audiobahns in a sealed box at about 2.7cf, and because of their design, they are incredibly cramped in my enclosure (go into WinISD and look up the Audiobahn AW1251 and let it select the optimum sealed b…

I have approximately 2.6ft^3 before displacements. This box is for 2 DC Level 3 10s. I'd like for the box to be tuned around 33hz, I planned on using a pvc/abs round port. What diameter should I use and how long should it be?

Can anybody tell me how much of the port length I need to get rid of in order for this box to be tuned to 32hz? Sound Solutions Audio - 15" XCON Optimal Ported Enclosure Please and thanks!

Hi, I would like some thoughts on my box design. From what I've calculated, the numbers work. I'm tuning to 35 hz. The colors are to distinguish the different panels. Also, please disregard the different thickness of the walls. I didn't want to have to build the box again just to make the thickness right. The curved corners are to represent where I will kerf. http://i.imgur.com/01zoy.png It is 15" x 22" x 16"(outside). Thanks

ok so my bro has a 15" l7.... seems to be alot of these mentioned in the forum lol. right now its in a sealed 1.5 cube box. a kenwood kac something something powering it with 900rms. car is a mercury sable with the mach audio system. currently the amp is using a loc to get single but my bro will be geting a mtx req or similar device later this year. theres no deading in the car and it rattles like crazy as is.... sorry to anyone who has heard and affended by the rattle... hes geting like 2 rolls of raammat for xmas from my parents we picked up some mdf and liquid nail today and plan to do a new box for the sub. im hoping to do a ported box with a pretty spl oriented de…

I have a chance to pick up some 6" aluminum tube from work for cheap. Would this cause too much of a hollow sound or echo? I plan on securing them in the box. Possible having an end made that flares. Anyone tried this?

Hey guys, Currently in the works of trying to figure out a box that will work with my Zv4. Here's some info: - Going in a 2000 f150 ext cab in place of the smaller rear seat.- Using my Saz-2000D amp- Sundown Zv4 12, suggested 2.25-2.75 cu ft- Wanting tuning around 30hz-32hz- Max Dem: W: 17 | D: 18 | H: 26 or so |- Would prefer sub to fire upwards.- I love rap music and bass heavy electronic similar to white clouds from decaf or lights from bassnectar. Here's my original box and design: http://imgur.com/a/WqOOl No sure how well it'll work and if there's enough port area. So here's another very similar box with a couple small changes that move me from 14.85 sq inch…

hello ssa and people with grand prixs lol. i wanna but a 15 fi bl in the trunk of my 97 gp. but idk how i can make a big enough box but still fit in in through the trunk. people with gbs can i get some box dimentions please that would be great. thanks for veiwing.

Ok I've had subs before but nothing too fancy just some 12" kicker cvxs in a ported box and running a 1200W (i think) MTX amp. Well i sold that and now I want something new. I have a 2001 Hyundai Elantra and don't care about trunk space so if the subs take up the whole trunk so be it. The thing is my budget is $1000 and I don't want to upgrade my electrical or get very technical with my system. I listen to mainly electronic music (trance, house, etc..) and rap/hip hop once in a while. Now i've read here that if your going for a SQ setup your not going for loud. I understand this, but since I do listen to rap/hip hop does this mean I am not going to be able to enjoy …

Live in Texas and the temp can range from 95 to 105 from May to middle of September. Just want know how to keep my amps cool from running and the temp being so high?

I have a DC XL m1 18 that i am wanting to put in my truck (02 Silverado 1500HD). I am thinking about taking the 60 part of my 60/40 back seat and making a box above my amp rack. I am wanting to tune to 30 hz or lower and would like to possibly do a hairtrick. Is it possible to do in my truck with a single 18? Here is what I have right now: 1 DC XL m1 18 D2 1 Crescendo BC2000D 1 Mechman 270 amp alternator 1 Stinger SPP1500D battery under the hood All 1/0 for big 3 and running to amp This is a box I come up with Would I need more port? Should I change anything else? And where should I place the port? the sub will either be facing up or forward. Should the port face forward…

I am currently designing a box for a DD9512g which will be on a SAZ 2500D. I wanna tune to 36-37 Hz with about 2.5-2.6 net volume. My question is: What has greater potential increase of SPL. A lower port mach or more port area? Thanks!

if you got a question just ask more than happy to help and if i can't i find the answer for you

I've had this sub for about a year and I want to build a new box for it. The first time, I built the port a little small (port area wise), so this time I'm going to make it bigger as well as increase the box volume. My plan is to make a box that is 32" wide, 22" tall, and 28" deep with a port that will be 20.5" tall, 6" wide and 35.6" deep. According to bassbox pro, that will give me a 29hz tuning. Does this sound right? Those are the maximum dimensions I can fit in the back of my Jeep while still keeping the port about 5-6" away from the hatch. Any suggestions? BTW, it'll be sub up, port back and it's powered off of a sundown SAZ-1000d. Also, do you think I'll need a…
