SPL & SQ / Fabrication

I have always been a sealed box guy,so I have NO idea how to tune a box. That being said,how much port do I need in a 1.25ft box with DCON 10????? Will be for daily use playing mostly rock/metal. I was thinking 40-45hz maybe? Please correct me if I'm thinking wrong.

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?

so a friend built this box for my 2 sa 12s its 34 inches wide 16 inches tall 22.75 inches deep port is 16.75 deep with no bend and 5.25 wide running off a sundown sax 1200d , just going to use it for daily driver no spl , i like counrty rock and some rap music . re box calculator says its like 36hz and torres box calculator says like 42 hz ,i was hpoping for 35hz could i just legthen the port a little or narrow the port to acheive this

I want to check some numbers but Im not sure if there are any trustworthy sites.. Got any?

I was wondering if anyone has done builds on a 97-00 Honda crv and how much space I should leave between the box and hatch?

I want to try out a transmission line box or quarter wave, whatever its technically called, and want to know if im off to a good start... I want to use a 10" Fi BL Dual 1 so 41.5fs with an sd of 310cm^2 = 48in^2 1130/41.5/4*12 = 81.7 inches... so my design looks something like this... I dont know much about these kind of boxes it just sounds like a fun project, If it turns out horrible I only lose a few hours and a little off my wood stockpile...What do you guys think about this design and these measurements?

when building kick panels for 6.5 comps would it be better to leave it sealed or to cut a hole and vent them into the inner fender. what is the sound diff in the both. thank you.

Like the topic says. Does anyone know how accurate the numbers are? Port Length Calculator Thanks

Hello all . Im in beginning stages of design for my 2002 PT Cruiser Enclosure. This will be my first year competing in the lanes for SPL. I know its correct to have a daily box and a burp box, but I would like to get as close of a mix in one box as possible. My initial thoughts would be to have subs facing up and slot port facing up as well because of the lack of room. So far I am just looking for any advice I can get. Max Dimensions: 39w x 20h x 14d. Would prefer port in between subs but If it doesnt make a difference, im flexible. Am I on the right track? Any help would be appreciated.

Let me start off with the basics. I have an '01 Accord and I'm looking to do at least 140 on music, but the louder the better, but I want it to sound pretty good still. So, in the works is possibly a 5200, whether it will be a 15 or 18, I don't know, thats why I'm comin to you guys. I have a 170A alt, Odyssey 1200 under the hood and 2150 in the trunk. I have an RF T30001 for my amp. I'll be able to do either a 15 or 18 ported (the 18 requires 5 cubes after all displacement). THis works great for me since I fit in an enclosure that was 5.5 cubes after displacement. Whether a 15 or 18, it will fire up due to height restrictions. I'm just wanting to know what will be the di…

Starting in March we will be starting our Thunder in the Park Series at the Colonial Village Fun Park. Stay tuned for more information.

So i have decided to build a custom box for my 2 10in type-s alpine subs. I found an equation on JL audio's website to tune a box and have been playing with numbers for about an hour now. Everything looks good to me i just want to have someone double-check to make sure im not screwing things up. The outside dimensions of the box are 11.5X31.5X20.5in. Using 3/4in mdf that would leave me with 5700 cub inches inside to work with. there will be a single vent, 10in tall and 1in wide, going in 5.5 inches. after subtracting the volume of the 2 boards used to create the vent and the 2 subs( 86.4cu in each), ill be left with roughly 5444cu in of internal volume. with the equatio…

This is my most recent sub enclosure, I designed and painted it. Looks way better in person too. Tell me what you guys think of it. Thanks.

So i was a little bored today and had an hour to kill. I figure, all the equipent I have laying around... I might as well put something in the truck and play around. Dropped in my old CRX-stlye box, pair of RE SX 15"s, and an Orion 2500D. Setup for 2kw before Imp. Rise. Ran a sweep, found the boxes peak with these woofers. Burped a couple of times. Then went back to a sweep to get a good reading before the batt drained too much. Stock Delco batt (3 years old). So far for this season in Street C, this would've put me 6th place. http://www.termpro.com/asp/leaderboard3.asp Not bad for dropping in and not testing anything. -Nick

So I couldn't sleep last night and decided to start designing the box I want to build for my 4 SA-10s that im getting in next week. Thought I'd post up the pics.... Also, After discussing yesterday with a few of you and trying to decide how to do port area and everything with some aero ports, I decided on the (4) 4" aero ports.. But then after I designed it and everything I realized that the tuning you guys said was about 39hz.... and Sundown recommends 30-35hz for these subs.. 39hz was like the only tuning we could get to work in order to get enough port area for my setup.. So I wanted to make sure before I buy everything and build this,.. Are the subs going to do/sound …

Ok so i'm pretty much done wt my box, will post pics soon enough, but. I'm not going to be able to reach my subs, once done, so if i connect each + and - to a bolt and nut on the box, that should work just fine correct? I'm sure i've seen it done before. I just would rather not run long lengths of wire to the amp.

in a hatchback, anybody personally experienced a setup where the subs were within 3.5" from the glass producing over 2,000w of power? Is there any danger or am i worrying too much?

Does anyone have any recommendations for a good table saw to be able to cut whole sheets of wood? Would want to stay under 1500. Will be for an audio shop

looking to buy a saw blade for my circular saw to cut my MDF. i was going to have lowes cut it, but i can't quit worrying that they will mess it up so im going to do it myself. i have been told to get at least a 40 tooth carbide tip blade....i am only going to use this thing once so i dont want to put a lot of money into it. i was thinking getting a higher tooth count blade, just not carbide tipped. i was thinking like a 120/150 tooth blade....would that work well? is the carbide tipped that big of a deal?

hi every have another question my step dad bought me another sa-12 as a late xmas gift and he gonna help me build a new box for my 2nd 12 gets here but the space i have is 39x16x22 1/2 which is w x d x h. now my question is is it possible to build a box for these two subs with this much space ? and how high do you think i could tune the sub's at as well if it's not i can add more height to the box.

I'm gonna be helping a friend build a box for 2 cvr 15's. It will be in the trunk of a 4 door saturn ported through the rear deck. I haven't played with cvr's much so im not too sure how to get the most out of them. Space is limited so i was thinking maybe 7 cubes with 112" of port tuned around 50. Starting it this weekend and could really use some help. Anybody have experience with these subs in different boxes?

I am using CAD right now to try to make a 3d design of my box. My question is if it is an 8 cu ft. box before displacement with external aeroports, what kind of internal bracing am I going to need even with a double baffle? This is getting a fully loaded 18" BTL by the way, with a Sundown 3000d. If I use 3/4" MDF will I have a problem with too much flexing? Also one question this is my first build, first system and I want to know what your guys preference is on MDF from different suppliers. All I really have around here is a Menards and I work there so I can get a small discount on it there. I just wondered what you guys think of the quality of Menard's MDF compared to ot…

Hey guys I built a box for my zv5 15 and used an 8" sonotube because of the port area and how aero port don't take up as much air space as a slot. A buddy of mines saw my set up and questioned if that port was too big for my box. i came to the conclusion of using and 8" port by doing some math and finding the port area. Which is 50" a little less than the recommended port area on the sundown website. But I'm assuming that's a slot port and I've read areonports require less port area than a slot so I guessed I was in the green. But after my friend brought it up I researched and found a site that said 6" is good for a 3.5 to 4.5 box. So I'm here asking for your …

Hi, I was wondering if anyone has made or heard a sub placed between the front seats. I have a venture mini van. I can have about 1cf of space to work with (id). If you have done this or heard a setup like this please let me know what you thought. Thanks, Duane
