SPL & SQ / Fabrication

alrite i started a thread on here not to long ago abou tthe elastomeric coating that steve meade used on the inside of the his box and didntt get many replys. i am pretty much done with glassin the inside of my box but i havent started sanding yet. i read about painting the inside with 2 stage paint making it alot louder becasue the waves travel better across a smooth hard surface. but the only problem is i would have to sand the inside to no end. i was plannin on sanding it to an extent and then sprayin it with spray filler primer and going from there. but i have a deadline in a few months and i dont know if this is going to be possible. another factor is that i will bea…

i am trying my hand at some horn's for the mids from my re6.5 comp set, the tweeters blew so i got new comps coming, and desided to put these in the living room. so how does this look? anything you see wrong or horn tips would be greatly appreciated

I recently bought 2 RE AUDIO SXX 12" woofers and plan to build the enclosure (vented) by myself (first time in my life). Since the manufactorer's web site only provides a box calculator for one woofer, can somebody kindly give me some advice on dual woofer enclosure and port measurement? In order for the box to fit in the trunck, the size constraints are: Length < 35", Height < 16.5". I prefer SQ over SPL and hope the bass hit as hard as they can. Thanks so much! The T/S parameters are listed below and more info. can be found on http://www.reaudio.com/woofers.php#goto_sxx Qes: 0.32 (Electrical Q value) Qms: 4.4 (Mechanical Q value) Qts: 0.30 (Total Speaker Q value)…

I have 2 AQ SDC2.5 with an AQ1200D amp. I have a 5 Cube box for them now but due to the fact that it wasnt planned out very good the box in crap and is all but falling apart now. I came up with another design but im not sure how well this will work. The subs call for 2.5 cubes a piece but with my new design it will be around 2.2 cubes a piece and the subs would be pointing pretty much up. I know that these are not ideal conditions for the subwoofers however how much do you think this would effect the overall sound. This is it any comments plz.

so ive built a few boxes before an they were simple an nothing special so i use a box calculater that i no longer have( computer crashed)! so im trying to build a box for this 15 btl fl to go in the hatch back of my 1982 mustang! i found a new box tuning calculater (torres) from smd site it has the height 1 an 2 an depth 1 an 2 so i figured hey it will work but it doesnt for me..it messes up an doesnt add height 2 in so i makes it just a square box i wana do 21" tall front 13.50" tall in back 17" deep an 35" wide.. with them specs i want sub up flush mounted an the port would have to go forward towards the top of the box! if that makes since.so THE would make the inside …

Well, I built the box as recommended by Bromo but somewhere when I was taking measurements I messed up. It is currently 35Wx15Hx19D. If I take 1.5-2 in. off the width and extend the depth? Would I still get the sound as before?

I just got a set of Dynaudio 240GT (MSRP 975$). Before I install them I was would like the best option for imaging. Is there a rule of thumb to tweeter placement (the woofer is going in the stock door location) but the stock Toyota tundra tweeter placement is high in the door, IMO the only place worse is the top of the dash. I don

I am looking for good SQ 12s... I have two Skar vvx 12s now and they do not sound good at all. They shake my car like crazy but I can not feel the bass inside or out of the car.. So what kind of subs should I look for to get the best SQ in my Chrysler 300? Bass I can feel and not see!

Ok I am doing a box for 4 fi ssd 12's. It will be 8 cubes after displacement. I need help with the port tho. I am wanting to tune to like 35htz. I kinda want to try flared aeros but don't know what size or how many. Can someone help me out. Also need help with the length

Just picked up a SA-8 v.2 and I need some help designing a box. Every design I find is for 2 subs, but I'm only going to be running one. This will be in a trunk car and powered by a DSC1500.1D. Maximum dimensions are 14" H x 36" W x 18" D

That was the 1st box i ever made on that other thread, lol, i dont think i ever tried it out, hmm. but here are the real pics The port looks extra small if you ask me.But its sposed to be 32hz Now i'm not sure if i want to add in this extra piece right here are not, if i do i have to cut it at an angle because the subs depth is more than my ports length Ply wood Did that even look like an 18in hole to u guys, ahh come on now Oh and does this need bracing of coarse

Would a box that is 2.046 cubes after all displacements with 2 ports that are 1.875x8x22" (will be behind my back seat in my truck) be ok or sound good or give me fair spl numbers with 3 or 4 sa-8s v1 d2s or 3 or 4 orphan 8s in it running off a crescendo bc2000? Is it enough port area? Box volume? Is there anything I should change?

Hey guys. I recently completed my build using an IA DR12 in 2.2 cubes at 31 hz. My port area right now is 25 in^2. I do get a some port noise on the lower notes in some songs. I was just wondering if I should rebuild a box using more port area. Just not sure if it would make a differance or not. It gets plenty loud right now, I just have had a "what if" idea in my head since I noticed it. Any input would be great. Thanks Tony Nelson

after building the enclosure, i want to paint the box, instead of using carpet. What kind of paint would i have to use. After im done painting it i want to add a shine to the box. I want it to be a shiney black color. What are the things i will need in order for me to achieve this goal?

My buddy wanted to go from 2 12s to 1 12 in a sealed so I built him a box for free and he gave some cheapo 12" sub as a thanks. I would like to build a 4th order since I never have and see how loud I can get this guy for shits and giggles. Problem is I don't know where to start on designing one.

First off, i know i already posted this in general car audio, but i just wanted to get as many opinions as possible, and i always seem to more replies in here than anywhere hahah. Sub: Fi BL 18 with flatwind and p chamfer Amp: Hifonics bxi2006d (again, its not sundown or anything, but it should get the job done for now and even if it is overrated, i think 1800 should push a bl just fine. Wiring: Knuconcepts.. look Not included in the kit are RCAs and the speaker wire. Also should i get 10 or 12 gauage, and what do i need to fit it into the terminal on the sub? Enclosure: 6^3ft after all displacement and port, and tuned to 34.4xxx hz. I guess what i'm looking for is the O…

Okay I am stuck in VA on Fort A.P. Hill right now and can;t make a new box so thats out for now. My 2 boxes are built for DD9512's and are tuned to 47hz. I want better impact from them. They are facing the back hatch with the ports next to them so it looks like one big ass box with a split port in the middle (if you can follow this). Anyways this is in the back of a 99 Ford Explorer XLT. No sound deadoner yet. Tryign to get more impact in my back. Thinking maybe slide them closer to the gate???? J

Does anyone know a formula that can be used to calculate the optimal box volume and tuning frequency for a particular subwoofer using the T/S parameters given by the manufacturer?

in a 2001 dodge ram ex cab fully deadened

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

this box im making for my ta is a PITA. having to make all sorts of corners and angles to utilize every inch of space in my well. coming along good so far, i've got the bottom half done, and im coming to where it angles and comes to the top of the box. how do i go about screwing in the angle? do i just countersink it further in on the outside of the box, so it doesnt poke out under the carpet, and put the screw in at the same angle as the wood?
