SPL & SQ / Fabrication

Anyone know of which programs professional fabricators use...?

I have a 95 Cadillac deville with trunk measurements of 47x23x17.5 I trying to figure out the best box for 4 dual 1 aa mayhems if anybody has any good feedback would help out a lot

How do you find or know your vehicles peak frequency? And how much high or lower than that should you tune you box for spl applications? I drive a 06 silverado extended cab.

Can I get away with using a single 4 inch port for my Icon 12? I don't have enough room to get 2 ports in due to the length. Lets assume the box is 3 cubes after sub displacement. Can be made smaller if that is optimal.

Short notice. Saturday August 9th! Xtreme Sound Cruise-In and Competition. 1701 Queen City Avenue Cincinnati, Ohio Registration begins @12noon... I'll be there with my TL running the SPL portion. We'll be doing a StreetBeat style, and a headrest SPL style... as well as cheap re-runs... -Noah

After searching for a subwoofer I have decided on the DCON 12" it seems perfect for what I am looking for. My question is regarding the box I saw the recommended plans were 2.25^3 at 30hz I think but I have plans already for a 2.5^3 box tuned for 35hz. Would the sub work well in that box or should I scrap it and just build the recommended one. I also have a 350 watt alpine amp, would it be ok to run the dcon at 350 watts? Thanks in advance for any advice/help. - Alex

I will be soon upgrading my current sub and box setup in my F250. I am limited on space and think I can go 1.5cu without much issue or maybe even up to 2.cu if I add an extension piece. My goal here louder deeper harder hitting setup. Here is a pic of the space I can work with and my current box. 1 10in Fosgate p2 in .53 sealed. I can easily double the size of the current box or I can make almost like a L shaped box to utilize the lower section behind the pass side. Without using the the lower pass side I think I could do one that is (17in H.. 33in W.... 5in D1.....8in D2) this would be outside diameter and I will be using 3/4 MDF. This should be about perfect for o…

ok so i got a 4runner and im running 1000 watts for a skar vvx-10 that should be here in couple days. Howevers i built a box at 1.25 tuned to 30 hertz and too me it seems like a big box just for a single 10, so the question i ask is the box to big or not tune right for my 4runner thanks

To have a loud LOW end and the SMOOTHEST transient response (not punchy) and DEEP overall which type of box should I get.

So I am thinking of venturing into unknown territory and build my first ported box. I have been doing a little research but am still learning. As I understand it, frequencies below the tuning of the box can cause the driver to "unload" which can cause damage. I am not 100% sure what that means, but I digress. I have read more than a few threads that say they tuned their box to 32 Hz and then go on to say that the low-end is amazing. Now I listen to mostly rap music, and it seems like to me that there are a lot of songs with frequencies below 32 Hz. There are a couple low notes in Jeezy's "Hypnotize" for example that I am guessing dip below 32 Hz. How is it that the box ca…

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…

whats the max dimensions that will fit through a trunk of a mustang trunk opening... wiered ass trunks

The Car:2000 Maxima The build i talk to some guys from americanbass usa they sending me 4 12's sq 600 rms subs im gonna need a amp to push them they have a 1000.1 they wana send me but i need to worry about the box build 1st thats where you guys come in..lol i need to build a box for 4 12;s ported threw my rear deck now on a ported enclosure these speaker need a box volume of 1.5 Cu Ft Now i Need to figure out how would i tuned this box out to 40hz thats the max the speakers can hold so i wana give it alls its got..BUT i have no clue on tuneing a box to 40 hz i can build a reg box to 12 ported slot in the middle but on the whole 4 12's i have no clue i hopeing one of ya c…

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 …

I just recently bought a FI Q 12D1. I'm looking to have someone build me a box, but he recommended i get him some port specs. I wanna go 2.3Cu FT and tuned to 33 hz. Anyone know how to get the length/depth of the port? I'm completely new to ported boxes, any help is greatly appreciated.

anyone?

Whats the best way to mount an amp on a sub box and not have an issue of the vibrations messing up the internals of the amp?

Just got metered on an Audio control...Did it with music. One song (The one I figured was the loudest) hit 145.0db! The song was Plies - All Black slowed by wattz305 All the other songs we tried were in the 140-143.5 range. I went in figuring I'd be happy hitting those numbers. Around 40hz seems to be the sweet spot. Still wish I had access to a termlab though.

The dimensions are" 20" Wide x 18" Tall x 15" Deep = 3.125 ft^3 external Internal = 2.385 ft^3 - .15 (speaker) = 2.235 ft ^3 to work with minus whatever port area??? a little area in the back lost to the plexi window that will be put in, but negligible The speaker is a Fi BL 12, with flatwind and pchamfer options. Tuning is suggested to be 32 hz and box size between 1.8-2.5 ft^3 I can't go much bigger due to trunk opening, and for that reason I am building to boxes of the same size and putting them in the trunk that way. I mainly listen to Rap/ Hip Hop and Hanna Montana ( ) These will be facing towards the seat so that the plexi rear is visible when opening the trunk. I …

Ok guys, I'm gonna need some help with an enclosure. First, some background. I have a friend who everyone had him talked into buying the usual kicker stuff, but luckily I got to him in time. This will be his first setup. Anyways, I coached him through buying an AQ2200D (could have chosen a better amp, I know, but his budget was sort of limited and we didn't feel like going through the hassle of looking for used deals on others), an 18" DC Lv5, and all the other bits. Should all be getting here by the end of this week. Alright now to the enclosure: The vehicle is a 2005 Tahoe Z71 (captain chairs in the rear). Now I measured awhile back, but if I remembered right, it should…

Do you guys think an 8" aero port would be enough port area for 2 12" zcons? They would be in about 6 cubic feet after displacements. On around 3500 rms. Tuned around 34hz. I want to go with a 10" port but an 8" would be a lot easier since I'm only going to have about 36" for the width. You think I should test it out and try or do you thinks its forsure not enough?

I'm new to this forum, so let me know if this has already been covered. I have a Carvin HD900 amp and a RLP15d2 driver and want to build an MDF enclosure. I would like to position the driver so it is downward firing and would also like to have port(s), perhaps on the rear. I would like to have a width of 20" and height isn't a concern. I think I want to tune to around 14hz (want something really low) and need to know about amounts of polyfill inside the enclosure as well as internal bracing requirements, etc. Basically the whole picture:) I'm gonna run 900w in 4ohm bridged mono mode for power (think that makes sense...lol). Please help!! Thanks!!
