SPL & SQ / Fabrication

I need a good set of box plans drawn up i have no problem building them.....just a noob at designing them i have all the t/s parameters ect... im really looking for a burp box i alreay have a daily box that does decent numbers on the TL ....just need something designed for the TL....Let me know if you can help me out. Thanks....

Most people who made them have stopped. Who makes the best ones nowadays?

So heres the deal I need someone to design a Transmission Line for one of my ICONS!! I have decided I want to start playing with a variety of different boxes. It will be a single 12in Icon or we could even do a Horn design which ever fits lol. It will be in my Hatch! So whos up for the challange I can get you Dims... I could also shoot you $5 dollars via paypal if you like..

Let me start out by saying that I have been out of the car audio game for some time, and I have never been as concerned with SPL as much as I have been with overall sound quality. It has been a mystery to me for some time as to why no one uses high efficiency subwoofers: for example a pro audio subwoofer. If the main concern is to get loud, why is this option never mentioned or even discussed. Many car audio subwoofers I see are in the range of 85-90 dB at 1 watt measured at 1 meter. Maybe closer to low 90s for a large woofer. On the other hand, many pro audio speakers have much higher efficiency, 95dB+ for 1 watt at 1 meter. To me it seems that efficiency would be…

Why do you compete? Since I opened, I will let you all know why I compete. I compete to have fun and to represent. One of the main reasons why I compete is because of the gear I run. Back when i started, it was about fun and there were plenty of Orion competitors, now there is a few of us, and I doubt that none are as serious as I with the Orion equipment. That would be the main reason, to bring back the Orion name to the competition arena, make them the proud people they used to be. Many of you might not remember Orion back in the days when Wayne Harris used to work for them, or when you could see atleast 40 cars at finals with their equipment. Not only am I bringi…

Simple. All anyone would have to do to receive competitor pricing is say "i do local comps". Hell if this were a way to get dealer pricing or even near it EVERYONE would say so. This kind of marketing is not in the companies best interest in any way shape or form. MSRP is where the money is at,.....period. What makes a person a decent candidate? One who actually listens to the questions he has asked. Done his homework, built 3026 different enclosures, pissed off his wife, neglected his kids, spent his college money, given up all hope of daily music, uses a product that can actually "get loud", is prepared to spend 1/4 of what he makes on traveling/admission/equip…

Why is it that many many build lately have a box similar to this: (no math was used- just a visual interpretation) I guess what I don't understand is how those lil flaps on each side are a port....just seems like an open hole to me. Are these boxes more musicl or SPL oriented? i am assuming SPL, as most that I see are in competition vehicles.

can i make the wicked one to house a single 15"? is so how??

So, I need to find a small, color, wide angle camera to mount in the mustang. looking out the rear window. Prolly mounted to the headliner looking through the hatch glass.... maybe in the hatch keyhole. Inversly, I'd also need to find a cheap LCD monitor to glass into the dash. not so big. 4-7". I need some kind of rearview mirror... a wall will tend to prohibit that. any advice? Google has yielded me alot of $500+ rearview systems for RV's & delivery trucks that are quite big & bulky. Thanks -Nick

Wood Thickness 0.75 Height 30 Width 38.5 Depth 15 Sub Displacement 0.42 Port Height 28.5 Port Width 3 Tuning Frequency 32 Port Length 29 3/16 I get Around 6 Cubes at around 32 hz, after sub and port displacement...i just want to be sure they are correct. thanks.

well yesterday i took all of my max dimensions and came up with 7.1cf. and thats before port and sub displacement.... so i have a few questions about this.... 1. will this box (after sub and port displacement) be big enough (doing 1 big single chamber) & 2. what would be a good port width to go with? jaycee said tuning them @34hz would be a good start but im not sure on how wide to make the port. any thoughts???? 3. i was told that in a truck, having the subs and port both up gets the best results. is this true? im using 2 10" kicker solo x's

OK i got this box made 4 yrs ago for my other car but it was a ported box for 2 12's. It was for 2 pioneer premiere ts-w12prs subs. Now i am not sure what the sub actually calls for on ported box but the is a review & Klippel Data on this sub here http://www.diymobileaudio.com/forum/...newthread&f=24 Its a slot port box btw The box is pretty big Here is the outer dimensions of the box Height:12.5 Width:36 Length:26 I am using 3/4 mdf wood Here is the port length Width: 4.5 Length: 11 Depth: 18 Here is the specs of my w12gti's http://manuals.harman.com/JBL/CAR/Bo...2GTi_rev_f.pdf I am currently using this box on 2 w12gti's with a sundown 1500d at 2 ohms which is 80…

i'm planning on running 2 orion hcca 12's and the box i'm planning on housing them in aimed at 30hz. it's dimensions are 39" wide, 14.5" in height, and 32" in depth. my port measures 13" wide, 8" in height, and 27 3/4" in depth. will these measurements yeild my 30hz goal. i'm not that good with measuring volume and everything so a little assistance will be greatly appreciated.

I talked to Nick at Incriminator Audio (Subwoofer Maker) I believe, he said go with 2.5 Cubic Ft per sub and a 70 inchs port in a 6 Cubic ft Box. 2x Incriminator Audio Lethal Injection 12 Inch Subwoofers. I did some further refinements. This is what I came up with Subwoofer Volume - 2.5 Cubic Ft Port Hz - 32 Box Specs: Width - 36" Depth - 26" Height - 14" Net Volume - 6.36 Gross Volume - 5.08 Cubic Ft Volume Per Woofer - 2.54 Cubic Ft Volume Displacement: 0.22 Cubic ft - Woofers .056 Cubic ft - Bracing 4x 45 Degree Corner Braces 1 Cubic ft - Port Volume Port Specs: Port Volume - 1 Cubic ft Port Area - 91.05" Squared Port Diameter - 10.77" Port Width 2" Port Height 12.5" P…

Final thoughts before I start building this for my sealed trunk wall? I am going to be putting in a Zv4 15" running on a BE.2500. Will it be alright for the total port area to be 12 in^2 more than the recommended? Thank you.

I want to go with a 4" aero for this temporary build. I am going to go 24x13x13 with 4" aero at 14.5/8ths long. Tuning will be around 35hz? Volume should be 1.5ish after displacement?

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?!?!?

Hello everybody I'm new here. I worked as a car audio and alarm installer 15 years ago. I have not had a decent system since...well...a long time. I bought a 1997 Honda Odyssey and I really like the van. I'd like to build a nice system. Can you give me suggestions on what components to use for a nice simple front sound stage that focuses on sound quality? I like "vocally" music. I also like dubstep and house music. I really like vocally dubstep. I also listen to talk-radio. I am thinking I am going to use a SSA DCON or GCON for bass. Maybe a SKAR 800.1 for a sub amp. I have no idea what components to use for the mids and highs. The head unit is a JVC KD-X50BT. I bought th…

anyone with the skills necessary to design a simple ported box and looking for a lil extra cash.. please reply.. need a box design ASAP

Sprint so I have a 06 tundra access cab with a fi x12 in I believe 2 cuft ported box tuned to around 32-34 maybe. But why do I notice such a big increase in "volume" of the sub when I put the windows down or open a door? This is probably a noob question but I'm just curious. Thanks. Btw it's running on a 400rms powerbass amp. It's where the back left seat would be. Standing up with the sub facing drivers seat and port facing the passengers side. Thanks

Is there any dB meter software you can use with a regular computer microphone on windows vista? i know it wouldnt be as accurate as a TL but its better than nothing.

Ok, so my front stage is composed of a pair of MLI 6.5's in the doors, and a pair of Fostex FF85k's (3" full range) in the dash. What I am wanting to discuss is windshield reflections. Where my head is normally is a slightly nasty reflection point, not sure how this relates to phasing issues, reflections, and off axis response. I noticed this awhile ago when reaching for something across my car while listening to a CD and noticing the change as I moved my head across the car. The MLI's and Fostex's are crossed over at ~400hz with the amplifiers onboard crossovers due to the fact my DCX bit the dust. The amps that are being used are a PPI 4240 and a RF 450.2 Thoughts …

this is my first time tooling around with winisd. my fi sp4 should be here any day and i'd like to make sure my box design is okay or if i should tweak it. ive seen port velocity used frequently around here and i was wondering how i can determine port velocity. is it for aeroports only or can port velocity be determined in a L slot port? can someone explain how to find out the port velocity for a L port. and before people start saying, yes i did search around a while on the forum and google and couldnt come up with the answer. thanks!

So here's the deal. I have a Sundown 1200D, a Sundown 125.2 powering my setup. I will breeze over the 125.2 which will be hooked up to 2 sets of Polk db6501 components (2 ohm load) on each channel giving me a net of 100 watts to each speaker. I am building a CUSTOM box for a12" TC Sounds LMS-R sub. This sub can handle 1k watts continuos and 4k peak. I can wire this sub to be a 1 ohm load which is a load my 1200D can handle (giving out 1200 watts). I am trying to decide if I should port the box I am planning on building needs a port or not, and if so how long, size, ect I need it to be. I believe I correctly modeled the Treo TE sub I have now (in a ported probox) in t…

This is a WINisd plot of my final 3. It is comparing 3 ETHOS 12's against an EVIL 18 and a pair of ETHOS 15's. The ETHOS enclosures were taken directly from some of Quentin's suggestions, and the EVIL 18 was a shot in the dark based on my space limitations. How accurate is WINisd in calculating real world SPL? Based on the modeling an EVIL 18 equals three ETHOS 12's at peak tuning (hard to believe); the ETHOS 15's win all...The EVIL 18 is pitted against the three ETHOS 12's for SB2 class reasons, the pair of ETHOS 15's is for I don't give a damn what class I compete in reasons.
