SPL & SQ / Fabrication

here is a link to some tables, but I would really love to build a TL or Snail Shell box soon to put a small sub in http://www.quarter-wave.com/Theory/Alignment_Tables.pdf

the vb part is the part that needs clearing up.... Vb= net internal volume of the box, correct? if that is the case, how is it written into the formula as square inches? bigger_george is building an enclosure for his rl-p 15's and needs to be able to calculate port length...however, he needs to plug in the Vb and he's trying to use square inches... here's the thread <-----click this link... so, which is right? i say Vb is supposed to be in cubic not square inches correct? wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

how do you find out about competitions.? i've never heard of anything in my area like this. i live in cincinnati. which is a big place. but i guess car shows and sound comps are limited. or... i just don't know where to look

I understand the physics of it, but Casey showed me the Pioneer Death Match winning truck that did deep into the 170's, can someone explain more? I want to understand about them, also when is it benificial to use one and when is it not? here is the pic of the wall

Yup I finally made a decision and the sub is in the mail!! My sx12 will be arriving soon and I need to build a box. I want to give it about 2.5 cubes after port displacement tuned to 34-35 hz. Building the box is not a problem, I got that part down. I just need help figuring port area/length. So any way you guys could help out would be awesome!! Thanks Tom

Ok so they have these so called SPL subs right like Re's new MT or treo's CSX right, ok so i was looking at them and then was told they were no for everyday listening.... ..What the hell does that mean, to me it makes it seem like if i'm not giving it a constant tone or something, the sub will mess up, dont really see how but thats what it seems like, now if they meant that it would be to loud for everyday listening...i'm game, that just means my car would be one loud SOB...just kinda stumped on this not for everyday listening thing...

Why did you get out of the competition scene in upstate abyway? I thought you had a good thing going. How high did the Orion setup ever get?

I am doing box plans for free (technically). All that I request you do is sign up for my free ipod link and do an offer. I do everything by hand and I will design a rough outline, cut sheet, and assembly instructions for you. Think of it as trading my time for your time. You can do that offer for free by going through the ancestry.com site.

Here is the show for an invite to Finals event_102404.doc

Okay got 4 Old ass but brand new in box, pioneer SVC 150 RMS TW-W33C subs from the local shop, for 100 bones. I figured it'd be a good start for 4 12's to mess around with. Well i built a Box the size of the Explorer XLT's cargo area. So thats 30" Deep, 40" wide, and 16" tall. (exterior demensions). Anyways made a port thats like 3" wide (give or take), and about 5" deep. Well what did I tune this thing to?? I have no theile small parameters, for the subs so it was just a shot in the dark for this project. Its almost as good as my 2 Vipers in 47hz boxes made for DD's. Anways this setup is prolly going soon. I am trying to get jcc's 4 Vega Vega 12's to put back there next.…

I am going, and I know team gates a a bunch of other big guns will be there, anyone else from here? I am rolling with Ray and the Caton Customs crew, but I am not going to show, I dont have time between then and now to prep my car, nor are my pods built yet

This will be my first show in over 2 years by this time! Last event I was in was the 2002 SLAP Finals where I was 4th. My system isn't designed for dB Drag so I will be outclassed a bit, but it will be fun to get into the lanes again. Here is the link to the show if anyone cares:) http://www.termpro.com/asp/members2.asp?Who=13&MemberID=6498

Just found out my old Eagle Talon holds the record in Stock 2 class in IASCA. Hmmm, How come I couldn't do that with the car? LOL. After several owners and some modificatins it is now loud!

I have 2 9515 DD's and I am building a new box. I need 75 square inches of port area. The square port I was going to use is 5 x 15 and is suppose to be 13.75 long. Do I measure the port from the front of the wood or the back? Also how far should my port be from the back of the box? I was thinking I might have to turn the port to get the length I need. The box inside measurement is 16" so the only would give me 2.25 inches from the back of the wood and 3.75 from the front.

My lil ass will be there with my bro from Tallahassee...just booked hotel and plane tickets. see he just busted a 159.5 Shane? Like 5th in the USA (SS1-2)..hell yea! more free chit!

i hope this is the right section butt.... Im still a nexb to box building and I want to make a ported box. It will house two sound splinter Rl-p 12s. I still need to find an amp so i dunno the exact wattage ill be giving them, but i want to give them like 600-800 a piece so thatd be 1200-1600 total. I want kind of an LSQ tuning so would 34hz be alright? (thats what the site suggests) If not then just tell me what you guys would think the best LSQ tuning would be. Then how do I figure out the dims of the slot port once i kno what hz i want??

I know I never start these topics, but I am wanting to build a really cheap fun Street B install for my truck once it is out of the shop, the most cone surface for Street B competition is 3 10's ok so I have narrowed it down to Options: 1 - the RFD 2210 (HX2 single 4 ohm 10") $109 2 - the Kicker S10D (round solo baric singl 2 ohm 10") $109 3 - the Cerwin Vega Vega 10" single 4 ohm $109 4 - dont sell my 2 eclipse aluminums and buy one more svc 4 ohm aluminum and compete with them (cheapest would be the 4th option, but I am hesitant to por them, warbleed really helped me out with figureing out a ported box design despite eclipse's lack of info for porting the Aluminums…

who let Joe in? I SAID WHO LET JOE IN?!?! YOU KNOW, Joe from CIA Engineering? Why you guys chasing all my sponsors down and making come to my hiding place? Hope you enjoy your stay here Joe. Might not be the biggest forum around, but the knowledge here and the people wanting to learn is strong here. Shane

What has been your favorite show you have attended, not necessarily competed in? I would say the best show (besides SBN) would be the first show at Ft. Drum, NY back in July of '00. It was a smaller IASCA show hosted by Terry Floyd. There were maybe 25 or so SPL cars and about 10 or so SQ cars. I met a lot of people at that show that wound up being good friends. Highlights from the show. I had the high SPL for the day at 151.0 I caught my car on fire! 2 of my other buddy;s got 1st in their respected SQ classes Here is a buddy's truck that won one of the pro classes. He went on to IASCA Finals that year. Real sweet truck.

hi all , just need dimenstions for a ported box, for one PIONEER sub TS-W121SPL its the same as the premier TS-2000SPL, thnx for help

My guages in my car are digital LCD. They are a teal color now and I'd like to change them to green. Can this be accomplished?

Tought to explain, but here it goes. I plan on using an 18" sub in my car. Due to size restraints it will be firing up into the lid of the trunk. Now, has anyone tried to make a baffle to go on top of the sub? The baffle would be touching the box at the back of the trunk and be touching the very top of the trunk at the front of the trunk. The baffle would span the entire length of the trunk. The sub would then fire into the baffle and create compression loading like in a hatchback. Damn, that is tough to understand. If anyone knows what I am talking about and has a better explanation than please feel free to elaborate. I just drew it up quick. I am just wondering if the …

Anyone tried this? http://www.splenduro.net/
