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

Does anyone in the eastern North Carolina area make kickpods or know someone who does? I'm not terribly skilled with fiberglass.

I am trying to plan how I am going to build a box to go in the ex cab of my toyota truck. I am putting 2 Fi Q15's in it. The space I have to work with is 53'' wide 17'' depth and 22'' tall. I was told to use 1 layer of 3/4'' MDF then after the box is done add a 2nd layer of 3/4'' MDF to the outside of the box to help reinforce it, is this right? This is the first box I have build so I just wanna make sure I get it right. But this is what I have come up with so far, how does is this right, the subs call for about 4 cub feet each tuned to around 33.

Does anybody know who i can talk to about getting a 6th order bandpass design. Thanks!

I have an 05 denali and want a 5 cu ft. box made. I went on re box calculator and my measurements I typed in made the box not square. Could someone give me a hand and give me some dimensions or a drawing???

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…

Aight, Ive got 2 18" daily Fi BLs dual 1 ohm, with cooling and flatwind option. Then I got a sundown saz-3000d, iraggi alternator, and more 1/0 welding wire than you could shake a stick at. Now I have very limited box building experince, and I know someone that knows someone, that has some experince. But I think he is limited in proper port designing, maybe. He has a shop called 352 Kustomz, small shop, two guys, do some crazy custom stuff. Very skilled in body work. So they start grinding away on my project, Its going to be more of a show box than a performce one. But he keeps on asking me the "port size" recommendation from Fi. I told him 5-10 cubic feet @ 30-37Hz , …

The dam thing didnt fit again, lol, but we took it apart and put it in seperate. The subs definitely move alot lot more, only thing is its louder but only in the trunk still , and now its flexing the side panels and trunk is now rediculous. i wish i still had my friends camera.. I'm hoping if i can stop the flexing the sound will go into the car instead of rattling out. ANy thought.s.. BTW the box i'm pretty sure isnt done right, but oh well for now

im planning on building a spl box for my 12" BL and would like some input from people with experience on a basic design to work around. for an spl box, i know people sometimes use a smaller box with more port area. my daily box is at 1.8ft^3 tuned to 33 with 26.5in of port area. approx how much port area would be ideal for this sub in say, a 1.5 cu ft box? im powering it with a hifonics bx1606d @ 1ohm and its in a 97 4runner, so anyone have ideas on tuning freq also?

o.k. i am not happy with the numbers i am seeing from my wall.so my q is can i cut a hole in the back wall and take it in to the trunk or make like a C in the back to make it deeper???i know it will change my vent and tuning.i am not worried about that.

I got everything ready to cut untill I forgot... What tall is the mayhem 12". I have it ordered but don't have it yet. On site says mounting depth of 7.75 inches. I don't know what that means.. Help pleaseeee

I have 2 ReAudio SE 12's. I need a box design ASAP. It's going to sit in the back seats of my 2005 Chevy 4 door 2500HD. So the box can just be square, port center or one side. I want it to hit low ( listen to rap and rock ) but at the same time be ok in comps if I want to go ( for fun but still like to do good. ). The reason I just want it a simple design is so I can remove the box when needed not much room behind the seats so that was not an option. I plan to make this out of 3/4 MDF as well so may need to brace it. I will need a design with all measurements of course. I am just going to have lowes cut the peaces for me. A 3D design would be great so I can see how it all…

Got a pair of MTX 8500 10"s that I am trying to sell (brand new in boxes still) but if they do not sell I am just going to use them. I am wondering what the best box style would be for a pair of these? I have pretty much unlimited space (Astro van) so that isn't an issue and they will be run on a XXX-6500D @ 2ohms so like 1500 each for burps, 700~ daily...

Hi all I am looking for advice on a design for a single ported enclosure to carry a 13W7 sub. The enclosure would be sitting on the rear right hand seat, directly behind the driver (Right hand drive in Australia). There are a couple of things I need to clarify first... Is the recommended internal volume of 2.375 cubic foot too small for this sub? If so, what would be a better size. Here we only get 18mm thick MDF (about 0.71"), so to make the front baffle stronger, should I just glue and screw two together? - Will it start to rattle / vibrate loose? If I make the box to JL's specs of 2.375, I would have to change the outside dimensions of the box to be (19.7" x 19.7" x 17…

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.

I have a visonik 12" woofer, that came from this set: http://ep.yimg.com/ip/I/millionbuy_2051_58365261 I am looking for some dimensions for a box, I intend to build it my self. I am planning low tuned, and ported. it will be in my room for the time being, so i would say slot ported, to ~28-32hz. size isn't an issue. And, it certainly wouldn't hurt to recieve a few tips for a first time builder.

I need help with designing an aero port enclosure. This is my first attempt. I am looking for 2.5 net and tuning 32hz, With corner bracing. I would appreciate all help I can get! Thanks.

Hey everyone, First off I wanna apologize for changing my mind so much. My financial situation has changed, so my future setup ideas have too. Even though I have not followed through with other plans ya'll have helped me with, I have learned a lot for each comment or post I read. On to the enclosure idea. I will be getting a single SA-10 D2 as soon as my current setup sells. I will be running it off of a BRZ1200 @ 1 Ohm (for headroom). My goals are for it to be decently loud (I have had an E-12, hope to be comparable to that), and flat sounding for all music types... From dubstep to decaf to classic rock to country. It will be in my daily which is the trunk of a 2000 H…

Knuconceptz 'Knucar' This guy might have an ssa membership, idk, but has anyone seen this? Everyone says 45 degree angles help airflow, so what would a perfectly round one do? It'd be near impossible to tune if you wanted to port, but if you could, would it actually work? Trust me, i'm not thinking of doing this because i can't make a sphere out of play-dough, just curiousity here.

ok...im gettin a cae this summer...((gas mileage purposes)) and dont know really anything about doin subs in cars....ive done trucks forever and know all about them but im dumb when it comes to what cars sound good with what....so i wanna hear some opinions on what setups yall have going in cars tht put up respectable numbers thnks, zak

I was wondering if the calculator here ; http://www.psp-inc.com/tools.html calculated it's tuning including displacement of the tube or without displacement. Thanks.

Hey guys. im buildind a new box for the sa8s. my dimensions are 56w 16d 8.5 tall. im shooting for around 35 sq in of port and 2.0-2.2 cubic ft volume. the subs displacment is .10 each driver. i put it into the re calculator ( i know its not exact) but i want the port in the center of the box and not one side or the other but thats not an option. i want the 4 subs facing forward and port back. anybody got some extra time to help me out? much appreciated!!
