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 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 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

Has anyone done a build in a newer camaro?

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.

hi, i have been doing so searching and i see that some people use clay as a spacer and i am wondering 2 things. how well they work and the other being how do you do it. cuz i need 2" spacers on the cheap side and all i could think of on how to get the clay to work for me is use something like these http://www.homedepot.com/webapp/wcs/stores...03+501959+90025 to give the clearance and then just fill in the space with clay and more then likely us fiberglass resin to make sure it is seal.

Hello, first of all please excuse my english, I am from Romania. I just received a fi Q 15 ( no options ) and I am trying to calculate my speaker enclosure. I want to go for sealed enclosure because I don't have much space in the trunk ( BMM e46 sedan ). Recommendations for fi q box is 2-2.6 cu ft. With my calculations I am about 2.5 but I want to be sure I calculate it right before I give the blueprints to the box builder This is my result, I am happy because it fits inside the trunk perfectly. I made a dummy box to see how it will fit inside the car. Wood is 1 inch thick.

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?

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

So i was trying to look for some pictures of a box terminal made out of ring terminals, nuts , and bolts. So i can have a idea on how to do it. Thanks.

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

I am trying to come up with a good design for a ported box for a 18" BTL. Now it is going to be in my trunk but I am going to try to get a full 8 cubic feet. It can be 41" wide, 29 inches deep, and the tallest it can be is 18.5" and that is exactly right size for a 18" BTL. The only problem I have had is that I know it is going to need some kind of bracing and since I have no idea how to go about that I don't know how to calculate in the displacement of the extra bracing, and I don't know how to figuire out how big I will have to make my port to be at about 30hz. If it is under 8 which I'm sure it probably will be I'm fine with that I guess, but I need some help on how to…

Awaiting a check for $450 and then putting a call into RE. 4 RE 8's 1.8 @ 34Hz dual 3.25" Ports under the seat of an '03 GMC 1500 Ext Cab. going to be powered by Pheonix Gold Octane R 8.0 Hoping for 140 on the AC. Which shouldnt be much of a problem.
