SPL & SQ / Fabrication

I drive a 2005 Ford Taurus, currently with 2 Kicker Comp 12s, which were my first install. I've been looking to upgrade to (significantly) more powerful drivers for a while now and I've recently taken on the job of research. I talked to a local Audiophile Loudspeaker company and he recommended TC Sounds LMS-R 12s. After reading reviews, I've noticed that their performance, while good, can be hit or miss. I did some more research and stumbled upon the AA Havoc 12s. These interested me more because of the (almost) 100% positive reviews and thumbs ups for SPL AND SQ. I'm looking to run these off of a Kicker ZX2500.1, giving them the 1250 RMS they're rated for (not overpower…

ok so i believe my sub box is about 1.08 cuft or very close to that. if i was to add this kit here... http://www.madisound...products_id=711 you think that would fit my application? in order to get 34hz with a single 3" inlet im going to need a "13.06364" long tube. if i got this kit i could cut it to length? what do you think? with a box of that amount of cuft do you guys think i should tune to a different setting aswell? let me know what you think!!

Needing recommendations on any and all used or heard systems with excellent SQ that have either personally blown you away or proved themselves in competition recently. Any info and opinion on the following are welcome with my proposed equipment in () Wiring thru KNU like always, damp pro like a pro, BIG 3, H/O alt if needed(pref not that much draw on a TL) and upgraded battery as install dictates. OEM integration - a must for this build sadly(360.2 by RF) sound processors (audio control, best model for needed corrections) component speakers - 2 sets F/B most likely fiberglassed to bring soundstage up (CDT, have loved every set I heard if installed right. Perfect for all s…

I'm working on a home theater sub. It'll be an aa avalanche 18 in an 21 cu ft llt tuned to 15 hz. I'm trying to figure out how to cut the complicated bracing in this box design. So I was thinking if I got someone to CNC the bracing I can cut the rest of the boards and will have a much easier build. Any suggestions are appreciated. Here is a link. And some pics of the design. I have the google sketchup file, and was wondering if it would be able to make templates of each piece and print them on a plotter. Then I'd cut them to size with a table saw and cut them out with a jig saw. Link to build post

What are the pros and cons of the 2? I have a box design for my 8 12's with a slot port but i have heard aeros are solid as well? some1 shed some light on this ^^^ original design

i bought a 4th order box from someone and i want to make the port bigger but not sure how much port area i should have. i was told by a couple people that for a 4th order i should have around 20 square inches per cubic foot of the ported section. the ported section of the box is 13 cubes so i figured 9" x 29" would give me 261" of port which would be 20" per cube. right now i only have 198" of port which puts it at just over 15" per cube. im not sure if this is the correct way to do it so i was hoping someone on here could help me out with this thanks.

Just made a new box for my 21" dp (the amp I will be running is a sundown 3500, I have (2) 1750 strapped right now about 3000 watts) in a 2000 Ford Taurus. (8.3 cu ft/32hertz) The sub is facing up, with a top on it to direct wave more in the car and stop trunk rattle. The port is firing in the car. (I guess its sort of a 4th order/ported box combo) During the build I wanted to make sure since the port would be firing in the car and the sub facing up with a top on it, to completely seal the front wave from the rear trunk. After the installation, it was loud but noticeably louder with the trunk open. Ok I must have missed sealing something..... I noticed I missed a few spot…

Time for a new design for my extended cab S10...2 sundown SA 12's going in, which way should the subs and port face, I have not seen much info on enclosures for these small trucks and I would like to have a plan before I start the project........I would appreciate any help

What do you guys think of this design? The huge ported section will be roughly 50 width, 36 Height, and 36 length all the way up to the back of my front seats. The sealed section in the trunk will have roughly 1.5-2 cubes per sub with the ported having over 30 cubes hopefully Give me your opinions of this design please Thanks http://img573.imageshack.us/img573/9628/boxdesign3.png http://img341.imageshack.us/img341/570/boxdesign.png http://img29.imageshack.us/img29/7765/boxdesign2.png does that make sense?

im trying to design a box for 4 sa-12's and i want to make sure its not too big. its 8.5 cubes after all displacements with 108 sq inches of port area. ill be powering the subs with an AQ2200D so each sub will see roughly 550 watts, which is why i made the box slightly bigger then normal, i just wanted to know if you guys think this sounds ok. ohh and it will be tuned to 32hz

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 want to have a smaller sub for when I travel or haul things. I currently have a 4 cu ft box with an re sx15 firing up and port back. It doesn't leave me much storage room in the back. Since I can't stack anything on top of the box, or by the port. So I'm thinking about a downfiring rear firing box for one Skar vvx12. It would be on the drivers side. Aprox 14" wide, 13" tall, and 27" long, with 4-5" feet on the bottom. The port would be about 4" off my hatch. I'm thinking about a slot port 2" high and 12.5" wide. Net volume 1.7 tuned to 32 hz. This is for daily listening at reasonable volumes. I'm looking for a 5-600 watt amp to run it off of. How much room should I ha…

okay so i just finished cutting and sanding all the pieces of MDF for the new box i'm building.. i used the re audio box calculator and it is gonna be tuned to 32hz. the only problem is that i am not entirely sure if the location of the sub will affect sound quality. just wanna play it safe and get some feedback. the specs are 30'' wide x 17.5'' deep x 14'' high. if the exact calculations are needed ill put em up. thanks

I wasn't going to do anything to my 2005 Chrysler 300c but that has changed. I have two ideas and need some suggestions. I'm replacing what is there now with a Fi BL15. Plan 1...sub firing forward into the cabin (cut out armrest hole and aim through there), port through the deck and seal off the trunk completely. Or plan 2...fire sub rearward port probably up (not through deck). In either case I don't want to go any deeper than the folding floor (approx 24"). I ran the numbers and can get 3.5 cu ft (after displacements) and tune to 33hz. I prefer sq but like it a little heavy occasionally. I listen to all kinds of of music but am thinking this setup will really sh…

Ive got (2) Kicker CVR Aluminized 12"s in a sealed box at the moment. I'm looking to build a ported box for them. Very little space in my trunk though, after replacing the POS factory Bose 6x9s. They hang down a little lower than expected, and also to note my torsion bar broke off the spot weld. I need some box dimensions along with ports and what not. I have a width=35" height=15". Can anyone help me please? It will be in a 2001 Acura 3.2CL Type-S and Im going for http://carphotos.cardomain.com/ride_images/1/2477/1341/6190670138_large.jpg this kind of look.

Hope everyone had a happy and safe holiday. Alright, I want to upgrade my front stage and would like some help with speaker placement, setup, installations and whatever else you guys suggest. Check my signature for the setup I currently have. I have a lot of time before I get everything and install because I'm in Afghanistan right now. So basically I want to improve on my overall sq because my speakers are lacking in the midbass area and want to change my setup and I guess try to go active and really experience a real sq system. I'm not trying to go all out in the sq area but I want to do a 3way setup and just upgrade my setup. Any help would be greatly appreciated. Than…

I'm going to build a box for a buddy of mine that has a 1988 Camaro Iroc-Z. It's not going to be in the wheel weld as of other boxes. But right behind the rear seats. In this picture where the amp is located, there will be an enclosure for them, and it won't cover up the whole trunk area. I am going to use dual 4" Areo ports, and I was wondering how long will they have to be to have a tuning of 32-32hz. I'm thinking 1.6-8 cubes in total for both subs, and the amp I am using is a Polk Audio 4channel 800 watt amp that will be bridged to run at 4 ohms. The aim is mostly for SPL since there is no true SQ. But he would like to be able to listen to a variety of music, such as:…

OK as of right now my box this like this. And now I wanna do this to it, if I take 1" out of the top and make it 18" tall it will make the box 7ft^3 net, and now i take 3/4" mdf and put is on the inside of the port and make the port 4.5H by 18.5W and keep it 16.5D It should tune it to 35Hz. The red is the new MDF in the port can I do this and will it work?!?!?

I was just wondering how much space between the end of the driver to the wall of the enclosure is sufficient? Meaning what wont hurt the driver or sq/ spl. I'm thinking of a 15" havoc ported. The xmax spec is 30 mm if that matters. Thanks in advance and merry Christmas to all.

Here is my dilema! I wanted an 18" BTL N2, BUT my malibu only has maybe 19" height in the trunk throughout. My dimensions to work with are something like 42 from wheel to wheel, 30 deep, and 19 Height. I am open to all opinions on what would be best. I REALLY want the BTL 18 but if everyone tells me 2-BTL 15s would be better I would obviously do that. I know the nightshade and SMDs like smaller boxes as well? I just bought a Sundown 2000d today sooo that will be my amp pushing w/e sub I get. I was also considering building the box out of the trunk and into the cabin therefore allowing the 18 or 2-18s to blow through the cabin in a wall type enclosure. Here are some pics …

hi guys will JBL GT5-S644 amp http://www.indiajbl.com/CarAudioDesc.aspx?ID=97 provide enough power to power up a set of Hifonics Zeus ZXi 6.5C component ? http://www.sonicelectronix.com/item_6713_Hifonics-Zeus-ZXi-6.5C.html please reply regards simmer

Hello all, I have been a traditional sealed box kind of guy, but I want to try something different. I am going to build a bandpass box for some SA-10's that will be pushed by a SAZ-1500Dv2. The port will be pushing through a ski hole in the back seat. The sub that I have now fires through the port, but I am hoping to eliminate some of the trunk rattles by creating a port that extends through the ski pass. I have taken a few pics to give you guys an idea of what I am trying to do. I want to fire through a port where the homemade ski pass, the trunk is sealed very well, so I opted to cut a hole. I have come up with some figures for the SA-10s by using an online ca…

So I know what SQ means and I'm not going 100% that route. I want something that sounds good to my ears. I don't want a flat band but then again I don't want a U either. I want a good blend of bass to midbass and no harsh highs, but I do like loudish tweeters. Not the cheap hood ninja ones where they have 4 sets. To start off, its going in my 01 Ford F250 CrewCab. I'm thinking of Headunit- Kenwood DoubleDin(no sure on which yet.) Subbass- 2 10 AA Chaos(Behind backseat) Midbass/Midrange -AA 7" CF mid(Factory Door location) Tweeter- AA Seas tweeter Processor- Not sure yet. (I like the RF 3sixty) Sub amp- Sundown SAZ1500v2(or 2000d) Mid amp- Crossfire VR404 bridged Tweeter a…

Ok i need some more help trying to figger out how big to make my port, it is for two sa-15's on the saz-1500d .v2 in a 97 Blazer. The box will be 19H, 38W, and 26D, subs up and port back. But i wanna put the port on the bottom centered and i was going to make the port. 6H, 20W, and 19L, but that didnt give me enuff port area and i want it somewhere between 32 to 38 or so Hz. So if someone could please help me out it would be much appreciative thanks.

I have a question regarding port length and how to measure it in my application. I have decided on one 15in FI-Q in a downfiring ported console encloser for my truck. Question is: I have attached a photo of an example I did and I don't know how to figure the length. And also, how do I figure the port area and will this be enough for a 15in FI Q. A SA-1500v.2 will power the sub. The port will be 3.5in wide and 14.5 in tall (inside diameter) but how long will it be? Looking to tune at roughly 30hz and the box will have 3.65cu after displacement if this works. Is it A, B or C. Red would be airflow Thanks in advance
