SPL & SQ / Fabrication

Hey guys i know this is a stupid question but when lowes cuts your wood are the cuts pretty straight. And what do they charge per cut? let me know. i've been having a hell of a time getting straight cuts with my saw and a guide clamp... for the most part they are straight but when the box is all assembled there is always a few corners that are off balance...

Ok so I sealed up the rear deck of my car, I have the MDF ready to be cut and set into place. My plan is to cut a 2" hole in the MDF to run my RCAs and power wire through, not sure how i can seal that up, any ideas? then im going to cut the speaker holes and mount the subs on the other side. that will be roughly 1" clearance from the back of my seat. I was going to try and find some rubber gasket at home depot to put around the MDF to seal it up to my seat opening surround. Does all of this sound like it will work out? Also im running a pair of boston acoustic g2 12s on my aq1200d for this setup

So I decided to make an amp rack. I figured I could make a simple wall cut-out with some simple cardboard templates and a skil saw. I spent the better part of the afternoon doing this. A Crescendo 3500 will go on this rack, I plan to make holes and grommets for all cables. I will put any distribution blocks or speaker terminal bays underside and or speaker connector block thing (Don't know the name). I'll update this as I finish it, and post it in a build log later. Just wanted to share what I did today! It's my first time, far from perfect or even clean looking. But this is a passion and a hobby of mine, and I want to do this all myself and learn from experience. I …

I am looking to buy some horn drivers from eric stevens just not sure how or where to order them. looking for some help

Which is better for making the outer part of the kick panels, grill cloth or fleece? I used grill cloth for my tweeter pods. It seemed to work great. I also read that others use fleece.

a great ssa member put this togather for me.... thank you sir!

So I want to build a false floor in the trunk of my Miata, to cover the amps that are sitting in the recessed well of the trunk. Never having done this before, and not too skilled at woodworking, how do I make a template design that conforms to the outlines of the trunk? I know they say to trace it out on cardboard, but how do you get the cardboard pressed up into all the nooks and corners of the trunk so the tracing is accurate, to trace out a line that shows the exact curve or square of the trunk floor? So the final wood floor basically press fits into the corners and walls of the trunk? My thought is to have a floor that covers the entire trunk, with the section cove…

Not sure how to explain what Im experiencing...but it seems that when running sine wave freq sweeps my system drops out about the 57-63Hz. Very annoying, and cannot seem to find a way to fix. I have 6.5 coponents in the doors (stock locations) and a 15" Xcon ported (tuned to 32Hz), doors have been sound deadened (dynamat,mlv etc) I have tried using different crossover settings (50,63,80,100HZ etc) to separate the sub and components, I have tried letting the sub only play these freqs, tried the components only, tried to EQ (my HU only allows 40,80...) Im just baffled...could this possibly be a Null from my listening position? Maybe the components being too far off axis? E…

this is ALTONS post "FYI the box is EXACTLY in the middle of the specs Fi gives for the 12" Q's. Fi recommends 1.8 to 2.4cuft as optimal for a 12" Q, 3.6 to 4.8 for two obviously. If you notice the notes I specifically mention 4.2cuft NET which means before displacements, there's nothing wrong with the space I've given for the Q's." and i STEALTH said "actually net means after displacements. gross is before. lol" ALTON said "taken directly from the dictionary buddy: gross    /groʊs/ Show Spelled [grohs] Show IPA adjective,-er, -est, noun,pluralgross for 11, gross·es for 12, 13; verb –adjective1.without deductions; total, as the amount of sales, salary, profit, etc., be…

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.

Hey guys, I'm starting to design my system that I'm going to be putting together this summer. I wanted subs that have """SQL""" type features, which is why I'm thinking the 12" xcons are the best way to go. The box design I have come up with is going to go in my 2002 Hyundai XG350L. I am going to seal it off from the trunk, and have the port coming through where the backseat center armrest folds down. sort of a skipass type thing. I believe that I will be running either a SAZ-3500 or an AQ3500 but I will make the decision when its time to purchase. Let me know what you guys think, weather or not it will work. I don't know if I should put 45's in or not a…

Price completly aside, how much better sound quality would you get with door pods vs components in a fully deadened door? I have a Crown Vic and my main goal is to get the best possible sound out of the components I'm gonna be getting. I'm going with the Image Dynamics XS series components. If I get them in the doors I'm gonna go with stock size 5x7s(XS-57). If I do the pods I'll go with the 6.5s(XS-65). Again my main goal is the sound quality of the comps so if the door pods sound just slightly better, than I'll pass. If the difference is dramatic though, its something I'm really gonna take a look at. I know there are a lot of variables involved in anything like this s…

Hello, I'm in need of a box design for a single hdc3.1 18 it's powered with a cab 1600.1 and the max dimensions are 35 long 37 width and 15 tall and would like it to be tuned to 32 hz but any suggestions and would be greatly appreciated!!!

I want them to pound, but I don't want them to take up all my trunk space, I want the box to be tuned around 32hz, so does anyone have any suggestions?

What is a good tuning point for a wall in a hatchback with 2 18's ?

Okay, so I had two questions: How does inverting your subwoofers affect SPL/""SQL"" if at all? & How would I go about making one side of my enclosure plexi-glass? (how to secure it to the box) Just asking because I've never done either before and was thinking about one or the other for my next build. Thanks guys!

I was simply wondering what is some of the different types of Building Material are the best? I know the word best is subjective, but in this scenerio, weight is not an issue. Of course, I could simply double up on 3/4 MDF, and do some well bracing, I'm aware of that. But I'm also aware that, the material your using can greatly alter the output. Thats the main reason extreme vehicles use concrete. I am not willing to use concrete. I know I said weight is not an issue, but thats a bit much, plus would put me into the extreme class. The reason I'm asking, is because this will be my burp enclosure. I've heard of some competitors using marble, and other hard/rock like materia…

hey guys, i used the re box calculator to make a box for my 10" fi bl. the box is 1.457 cubes for my sub after port displacement. the port is tuned to 33 hz. it doesnt sound good at all. i followed the cutsheets and everything and there is no leaks in the box that i can find. im just kinda wondering why it doesnt sound good. also, i used 3/4 inch mdf for everything but the baffle and the back. i used 3/4 plywood for that. could that be why it doesnt sound good? please any help would b great. thanx.

15" Xcon .... Was thinking about going sealed but then the idea of aero ports was brought up and I saw Stef's and loved the look and thought ... "Hey, a sealed enclosure is just a big box.. and a ported with aeros is just some tubing thrown inside of it and cut to the right length for tuning... I can do that.." Should I just do this? I was looking at PrecisionSoundProducts and said I could do this... Not much more work that building a sealed enclosure... Right??? So I looked up on their site for ports calculations and realized after understanding it a bit better that the Torres calculator does it as well... Here is what I come up with and it seem correct... Let me know wh…

Okay, So to find out what Hz my car peaks at, do I try out different test tones to see which one is the loudest in my car? If so, then what do I do from there? Say my car peaks at 37hz...do I tuned my port to 37hz? Reason asking is because I built a 2.5cuft. net @ 32hz enclosure with a 4" aeroport. I can take it out and cut it down for SPL. I just want to do it right since I only have one tube insert left. I'm aiming for SPL, not a fartbox. Thanks!

Hey guys! This is my first post on this forum, so please excuse me if I'm breaking any protocol. Anywho, if anyone's interested in Digital Designs' new T series subs, check out the link below in which I posted my build thread. I realize it's linked to Elemental Designs, but that's only because I was initially considering the use of their 8" sub. I can't compare the two, but let's just say that I am THRILLED with the performance, sound, and appearance of DD's T1508. I couldn't ask for anything more... well not from an 8" sub. Don't take that the wrong way, though. If I were to compare to anything at the local Best Buy, I'd have to be looking at a single 12" or a pair of 10…

Hey everyone. What do you think would be the best for music and spl box size for a 15" Zcon. Been looking but can't find the suggested box sizes on here. Thanks guys.
