SPL & SQ / Fabrication

...need some mad pound wang up in here yo... LMAO Can ya hear me now?...Good!

Just bought 2 of the old version BTL 12s loaded with the 3rd mag and everything. But Im trying to save space for more room for my batteries and amps. My amps are going to consist of a T40001BD and a T5002. Im going to do a semi blowthrough in the trunk of my Thunderbird in which the back seats do not fold down but Im going to cut out the rear armrest and use it to help let bass escape into the cabin. I wanted my enclosure to be subs and ports forward sealed off from the trunk. I'll have about 8" between the back of the seat and the front of the enclosure. My deminsions will be (double baffled) 15"H x 38.25"W x 23"D. After sub displacement,bracing, and 45 degree corners (r…

So... me and my dad are in the process of rebuilding a 1970 vw bug, and of course... i plan on putting a system into it. the main problem will be with the placement of the subwoofers, bugs are tiny vehicals with almost no extra space. we would prefer to keep a backseat but would be willing to give it up if need be. So does anyone have any ideas for a good subwoofer and somewhere to put it. money shouldnt be too much of an issue but it must be within reason... Im going for SQ but would still like it to get hella loud. i was thinking maybe 2 10in Fi SSds in a sealed box... any ideas or suggestions would be appreciated. My next question isnt really fabrication but while im…

Just waiting on getting my two 15" icons and, since I have nothing better to do I was wondering if there was any box type or orientation you'd like to see me try in my 2004 Impala. I'm going to try a ton of different boxes and orientations with a lot of testing to see what works out best in my application and I wanted to have some fun with it. I'm NOT doing a wall, but ill be pretty open to anything else you'd like to see me try. I might actually end up using your idea if it works out the best! -Mike

Help me out. I can't afford a ton of batteries so I can only go into a class with minimal bat requirement. :boxin:

i currently built my first box ever...and it came out pretty good...there are some minor gaps...which i believe are due to warped boards because all cuts were made by me on a table saw...but back to the point...i siliconed the crap out of the inside and silicone into the port (around the port pieces and one of the other corners) will that change anything such as tuning? or increase the liklihood of port noise etc?

Since my local box builder seems to think he needs $270 to build my sub box I decided to tackle it myself. I have been reading up on box building when I came across a forum that suggested making a box panel that sandwiched a layer of cork inbetween 2 layers of mdf. Another suggestion was to use sand inbetween 2 layers. As the latter isn't feasible, I am interested in the cork option since it is fairly cheep. I understand that the cork is supposed to help dampen the box. Has anyone utilized this practice? Or are they blowing smoke? They also suggested using dynamat instead of cork, but that seems a bit pricey.

i did a 149.3db this weekend got 1st place my 4-15" box was still wet ! the FG Resin had not dryed and i had no time to brace the boxx i beat a guy that had 16 > 12" subs he had this he got a 148.9db & 2nd place

http://www.craftsman.com/shc/s/p_10155_12602_00964473000P I found one of these at a local pawn shop and was wondering if it would be worth picking up for 50 bucks. The one at the shop has a attachment that looks something like a router and has a circle cutting attachment among other things. Really would just need it for cutting circles, and then possibly other household things. Sorry if this is in the wrong section didnt really know where to ask about tools here.

Hi I'm making my box for 2 12" Fi SSDs and I can get my dimensions from the RE box calculator but how could I calculate a double baffle into it? I have been thinkin about it and I can not think of how I can calculate it and keep it at 4 cubes.

in a hatchback, anybody personally experienced a setup where the subs were within 3.5" from the glass producing over 2,000w of power? Is there any danger or am i worrying too much?

Hi.. this is my first build so i have little experience right now. Im getting 1 ICON 12 with either an AQ1200 or an AP1500 amp. I drive a 2000 jetta, the trunk is about 40 inches wide. I am not really sure what type of enclosure i need, the specifications for it, or where to get one so any help would be nice.

Hi Guys, Hope you are all well and i aslo hope that some one can assist me with working out the correct spec for a true SPL box. please note I will only be doing SPL with this box. Ok so I have 18mm ply wood, 1 12inch subwoofer, 1 amplifier and 1 battery. Here's what i'd like to do Get a minimum of 151db's from this setup Equipment DD Z1a NSB 170 12v Targa TG301-DW The sub specs are as follows and i could be wrong because this is taken directly from the site. 12" COMP SUBWOOFER - DUAL 1 SPECIFICATIONS Fs (free air resonance): 48.7 Hz SPL (efficiency, 1W/1M): 89 dB Nominal Inpedance: 1/2 Ω Qts (total speaker "Q"): 0.606 Qes (electrical "Q"): 0.732 Qms (mechanical "Q"): 3.5…

Is there someone out there who can help me with a custom enclosure design with a single 10 inch jl audio 10w6v3. The enclosure i am looking for would need to be 1 cubic foot with aero ports tune at 35hz. As far as space i have to work with i draw a simple image of what the space i have to work with.

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

I have a weird question; I plan on attempting to build some Kick panels. I have some Fiberglass and Kevlar material that might work. But I want your opinion. All this material is about .015 -.035 thick per layer, yeah it would take a lot of layers. This is a Spun-lace polyester material, Its 4

What is considered the windowline in a competition vehicle? My doors and my trunk windows have a different height. Also, do they have no wall classes with a height limit vs the window rule?
