SPL & SQ / Fabrication

Would it be possible to make a box out of the clear material and have it sound just as good as MDF if not better? I think Id like to go that route, why I dont know but a clear box would look cool to me.

I have a 98 single cab ford ranger. Idk if I'll be satisfied with shallow mounts. I've been looking into the fi q. I really think I could fit it behind the seats with he sub directly behind the armrest. I think the recommended sealed volume is about .6-.8 cu ft for one 10" , and I've always wanted to try a Q out. Especially for lows. Anyone see any hope in this? I'm starting to become a little discouraged. According to box calculators, I could make the box out to about .8 after sub displacement. If I should just stop wasting my time and settle on shallow mounts, please give me cheap recommendations. I've never really heard one.

i've been at this for awhile trying to get a design for 2 15'' lvl 3's.. i wanna go subs up port back in my tahoe. any help would be appreciated.

hey guys, i was looking for the recommended enclosure size for the eclipse sw9122, and i cant find them anywhere, my specs of my trunk are 35" wide, 20" deep and 22" tall...but that is way to big for this 12 i would think. i have been searching google and bing for about 2 hrs and all i can find is what other people have used. any help would b great. thanx.

I have 2 12" DB Drives the model number is: PLW12D4. I would like to know what the total dimensions for a box should be like the inside area and the LxWxD should be? What should it be made out of? How the port should be and where the port should be? how many Hz should it be for the best possible SPL? Also, the box is going in a 1997 Ford Thunderbird. Right now I have the subs each wired to there own amp and the amps are Crunch Pzi1500.1 so are these amps good enough or should I look into buying a new amp, If so what amp? The subs are rated as follows: 2000 watts total power and 1000 Watts RMS. I don't think I am powering them to there full capacity. So any sugges…

I think I got my first box design down, hope to have you guys double check it all for me....... tunning will be at 35 hz. port area is 62 sqaure inches box volume is 4.29 ( havn't figured out what the 45's and braceing will displace) I just used 4 cubes for all my math. useing 3/4" mdf and will use double baffle. port opening will measure 15.5" W X 4" H , useing the bottom of the enclosure as the bottom of the port, ported to the side. port length will be 27.5" long the port will fire toward a vertical mdf wall on the drivers side. sub will fire up, and i will plan on having it inverted, for now. it will work out that the sub will be almost centered in the vehicle. kee…

hey guys, i have a 18" fi q with bp power. im running it off of a 1600 rms hifonics amp. i have it in the back of a focus hatchback in a 6.3 cubic foot box tuned to 28 hz after displacement. my question is, if i take my backseat out i can build a bigger box. i dont use my backseat much so idc about that lol but say i built a 8 cubic foot box and tuned it the same, would there be any difference? if so what would the difference be besides no backseat?

i've been making and tweaking a box calculator the last few months. it's come along nicely i'd say. it's been over on *** (i'm ExpoSport over there...and if it's possible to change this name to ExpoSport me love you long time so after getting it tweaked to a good point i figured i'd share it elsewhere now. one thing that is still in the works is an open/save feature so you can save designs instead of printing or writing them down everytime. this is mainly for square/slot ports. plain boxes will be easier to do, but if you build a box in the car for example, you'd need to figure out the volume on your own and then fill the boxes in accordingly to get that volume, and then…

What size enclosure would best suit a 15 L7 for spl and tuned to what frequency

How do i tell if its my sub or my box or my tuning that is making certain notes hit weird like the song run this town by jay z sounds like s**t in my car. Btw i have an L715 in a 4.44 cubic ft internal box tuned to 34hz and it is ran by a kx1200.1 that does 1400 rms. Thanks.

Im a noob at woodworking and have a couple of questions for those that are experienced with routers. I currently have a porter cable fixed based router i snatched up from a pawn shop for $20. I wanna get a plunge router as well in the near future. Collet size is not an issue because both routers are 1/2 and 1/4 shank interchangeable. What kind/size/length bit do i need to do hole cutouts and also what size bit for roundover's for port edges? Assuming 3/4 mdf is being used. Thanks

so i inverted my 18" fi q today and have the motor sticking out...it is alot louder. i can now do a hairtrick, which is what i have been striving for lol, my question is....why does it make it louder? is there any theory behind it or is it something that just is?

Hey, I just built my first box. 2.18 cubic feet tuned to 34hz, for under the seat of a 2003 Silverado. The box sounds great, but looks horrible. So, my questions are. Do you use wood glue to hold the box together? Or just screws? Do you use screws or nails? What type of silicone do you use to seal the box? Help is greatly appreciated. And for those wondering; the box was built for an RE Audio SX 10", so far we've tested it with a Soundstream SPL 10" and it sounds great, the RE should be here in a few days.

Anyone have the meca world finals results? Just curious on how our shop vehicles would compare..

Alright heres what i have. 1 Kicker L7 15 Dual 2 Custom Ported Box 4.44 Cubic Feet Internal After Port And Sub Displacement Tuned To 34 Hz Kicker Kx1200.1-1400 Rms Alpine HeadUnit KnuKonceptz Kolossus Fleks 0/1 Gauge (About To Order) KnuKonceptz Krystal Klear Subwoofer Rca's (About To Order) Sub Is Firing Against The Rear And Port is On Passenger Side How Does That Setup Sound To You? I Know The L7 Isnt The Best Sub For Spl Or Sq But I Like The Way It Sounds. So Thanks For Your Opinions

box dimensions 38 * 13 * 15.98= 7894.12 in³ = 4.56835 ft³ tuned to 32hz Bracing with 1 in dowel rod up/down r=.5 h=15.95 3.142 * .25 * 15.94 = 12.5 in³ = 0.007233 ft³ front/back r=.5 h 12.97 3.142 * .25* 12.97 = 10.188 in³ = 0.005895 ft³ probably two of these.. perpendicular or parallel so this leaves either 4.553884 for parallel or 4.555222 for perpendicular, up/down and front/back plus sub displacement of .19 4.363884 parallel.......... and for port area, with 57.25 in² slotted, ~50% for aero is 28.625 in² so a 6in aero port will be about 13.62 in long with the flare, with 28.26 in² without. round is also about 55% more efficient than slot so.. i think all my math …

Im Helping a friend design a box he kinda wants a half wall. Two subs inside the cab ( no rear seat) and two in the trunk area. My idea is 3.5 cubic feet per sub about 55 cubic inches of port per sub. It will b one big box but inside it will be like each speaker has its own box and they all have their own port. So i suppose 14 cub ft internal after sub and port displacement and overall about 220 cub inches of port how does that sound any advice is appreciated. He has none of the equipment yet but he wants 4 cvr 15s and for power either two kicker kx1200.1 or one zx or kx 2500.1?

Hey guys just need some advice here. I have a 98 Dodge Ram Extended cab and plan to install a BTL 18 in the back. The seat will come out and I have ample room for enclosure. I just want to know if anyone else has done this kind of install in a similar truck and I basically want to know if the FI specs for box will be the best, maybe someone else has found something that works better. I have an Exile X2400.1 that is going to push it. I listen to mainly rap music and I want that sucker to pound. I already performed big 3 upgrade and have cap ready to go, my truck is diesel so I have 2 batteries already. I figured FI's specs for enclosure are on the money just looking to see…

Need suggestions on bracing for this box. Would a single 4x4 in the center of this box be enough bracing for top to bottom. I haven't added bracing from side to side or front to back yet. Total top width is just over 52 and bottom is just over 41 wide 38 deep and 18 tall designed for 4 12's

In anyone's experience, does it matter if the elbow of an L-Port is angled or kept at 90*? As far as sound quality or output is concerned.. It would be easier to build boxes with a 90* angle like that found on the RE box calculator. I've always used an angled elbow, as shown below.. It just seems to make sense, but just wondering!

i just got a lightning audio storm x2.h15. v4 and ive been looking for a new recone does anyone know where i might find a new recone?

i was reading the new england spl site and i see it other places what dose CRX mean and why cant you have it

my buddy steve has a pair of audiobahn aw120q (12") what would be the optimal airspace and port tunning for them thanks chop

Ok. So I keep hearing different things from different people. Maybe some people over here have some decent advice since im not getting it else where. So I have a DD3512. DD recommends 2.5cu ft ported at 40 hz for their enclosure. Some of the local guys here who run DD say NO. that I need about 4cu ft ported about 36-38hz for one DD 12. Then another guy I was talking to online who tests TS parameters and sub on a daily basis says that the 3512 can play great in a box down to a cu ft. but is good in about 2-2.5cu ft ported at about 34hz. WTF?! All these dimensions contradict eachother and I know DD isnt a super woofer that can play in anything so someone help me out …

I am trying to help a friend build a wall in his '05 denali.. He has four 18" FI BLs and he's wanting to keep his second row seats, third row is gone. This system will be used for USACI SB4 and daily use to please the crowd.. Any help with a design or anything will be appreciated!
