SPL & SQ / Fabrication

if i bought 10 of these and made a super big ported box ( i think they are supposed to be IB?) would it sound worthy of the money i spent (slightly more than the daytons)? spl is more imporant, but sq cant just be dismissed. I found a ultra cheap in-wall 8" subwoofer. 22 bucks. thump option 2 I would be using those instead of four dayton 12's Boom option number 1

I got a box built for my 2 Funkin Audio 12" subs but something is wrong with one of them So I used 2 of my Mass destruction napalm's I had never used them before. I had the box built at 2.742 cubes ported to 40 for the funking audios the Mass destruction napalm seem to be doing ok and they seem very very loud.. My question is do you think they will be ok in this space or should I get 2 of something else like the BTL that is good up to 3 cubes.. I am running a xxx-6500d and they seem to be taking it ok I don't want to push them just yet as they are brand new. Open to suggestions don't want to smoke to new subs for sure.

I bought a box i just saw some of the glue is coming undone so im gonna glue it again and screw it down and seal up the inside. But i need to know what it is tuned to here are the measurments thanks in advanced. I have an L715 in a ported box the measurments are 16" h 40" w 17.5" d and the port is 3.5" w and 13.375" deep. I would like to know how many hz it is tuned too and how many cubic feet it is after port and sub displacement. Thank you

im building my third box but first wall and i always wonderd if when i calculate the cubic feet of the box do i subtract the port cubic feet??? i have come up with a box thats 17.5cf but the port is 2.4cf and each woofer is .25cf so its like 14.6cf .please some one correct me if im wrong im not to sure

So I just bought a single Nightshade 15 for the trunk of my 2007 300C. I'm just gonna figure out what works best for the box so as to not block my spare. I was considering porting a box towards the back seats, with the sub inverted on the back of the box (so you can see it when you open the trunk). Any problems doing this? Having the sub inverted would let me fit the box more tightly towards the seats in my opinion, but I'm new to box building. Thanks for any help

hello all! i just ordered my 18" FI BL driver and am working on designing a box for this beast. i figured id go big as i am leaving for basic training(US Army) in about 6 months. Im looking to take the backseat out of my jeep wrangler and replace it with a fairly large box for this woofer. iv built some smaller sealed boxes and they have all come out fine but this will be my first time building a vented box any advice that you can share would be amazing and i thank you in advance. As far as the sub goes these are the specs that FI gives for it, i measured out my jeep and got some measurements that would work, i came up with a width of 32" a height of 16"(was planning on h…

I was looking @ this video and this guy made this video with 4 15s and it was 2 of them at the top and 2 @ the bottom.Anyone an expert on making these kind of boxes I want one made in my car. here is a link <object width="425" height="344"><param name="movie" value=" name="allowFullScreen" value="true"></param><embed src=" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>

Building the box tomorrow. 2 JL w7 8 Inch subs (sold the 12's, these are to cool looking). Sealed or Ported? Used for Rap Music. These are each being powered by a JL 500/1 until I order Sundown Amps.

Hey guys, Will be building my first box in the next week or so and I really just want to make it right the first time so i would be really grateful if you could check over my numbers before i go any further. Specs 2003 Ford focus 12" SI Mag re coned with fi softparts. So basically its the same spec as a Fi Q Aim 32 hz @ 2.5cuft (biggest recommended box for this sub) Subwoofer displacement - 0.16 cuft Port Displacement - 0.69cuft (Really didn't know how to work this out! Do you calculate the port as a separate component or just account for the wood that makes the port if so this is wrong) Baffles displacement - 0.10cuft (in my design i have quite a few baffles to brace t…

I am wanting to try building a enclosure with a flared port and was wondering exactly how to do it if anyone can help with this i would really appreciate it.

As per title lads, with my equipment coming soon I wanna go with the loudest design possible, will be using 2 AA Mayhems with 2 Hifonics 2607D's to power them, have a nice bit of room to play around with (say a max of 25-30cuftexternal) Will I go flat wall Port up top?? Flat wall port drivers wide?? Clam?? Small Tunnel?? I'm not really pushed about numbers as I want this to rattle people (will tune to maybe 30-32hz) All suggestions welcome guys

hi everyone, I'm posting yet another topic to see if I can get any more excellent advice. In a previous post I stated that I was gonna build my own box. I know I want a sealed box. My goal is a real flat response. In my literature for my subs (Phoenix Gold titanium elite) they list 2 different recommendations for sealed boxes they are as follows: {Musical: Vb 1.6, F3 33 Hz} {SPL: Vb 1.0, F3 36Hz} My question to you guys is, Since I have 2 subs, What would be the outcome of making 1 box to musical specs and the other to the SPL spec. The speaker placement will be under the rear deck lid with subs facing the rear of the car. Car being my Chrysler 300. The box will be made…

VanEQWizard Background noise floor fluctuates from 65dB to 78dB... pretty bad when nothing is playing! I can read these pics off PC but not from the threads so: 5.22% 300Hz sounded so much louder than 200Hz yet it was so much quieter... that is why KW likes a U shaped FR curve, more and more exaggerated as you get further from the middle 1.97% 1.97% 1.42% .844% .937% .253 .235 .235 .402 .217 .576 .229 .270 .259 .376 .208 .672 idk what happened .0343 IDKY but dist stopped showing here. I was clicking it though. couldnt even hear 18,000 so i stopped after it

ok, i done a trunk build but ports not tuned right and i want to get lower and louder so im going to be removing the rear seat in my 95 fleetwood and thats where the box shall go. i want to keep it at window line so these are my max measurements to work with height 23" depth 26" width 56" height really needs to be 22"-23" but the width and depth can be smaller if need be, with those specs its around 16.5 cubes before subs and port, i want to be tuned around 32-33hz for rap music whats the best size box for this application, please help, any help is mucho appreciated

in a 4th order bandpass, is it generally better to have the magnet in the ported section or the sealed section of the box? it seems like you would get added cooling from having it in the ported side, but would the motor obstruct airflow to the port?

Last time i made calculations I didnt account for a few things including the end correction of my slot port. I hope somebody with a lot of enclosure knowledge can help me out with this. Port Area 126 inches2 Port Tuning 32hz Port Internal Dimensions 9” x 14” x 39.85” Port Displacement (8.25” of the port will be external)(31.6” Internal Port) 9.75” x 15.5” x 14.25” =1.24625651 cubic feet 9.75” x 15.5” x 12.1” =1.058 cubic feet 1.24625651 + 1.058 = 2.30 cubic feet + 0.18 cubic feet (Subwoofer Displacement) = 2.48 cubic feet (Total Displacement) Subwoofer Dimensions Needed (9.23 cubic feet) 36 x 15 x 35.75 = 9.231 cubic feet before displacement 9.231 – 2.48 = 6.751 cu…

So I was looking at pics of banginAltima's Altima and noticed the external aero ports were facing into the car thru the folded down rear seats. I'm building a box for 2 Fully Loaded 15" BL's and was wondering if I can do something similar. However, theres a catch to my set up. I have a 88' Grand Marquis that has a solid, non-folding rear seat. So I was wondering if I could make custom external aero ports thru my rear deck between the 2 6X9's. Would that have the same effect as it did in Altima's car? He gained about 4Db when he re-designed the box and port set-up. Or am I just being unrealistic?

Okay, have done some reading around, and from what I'm seeing is that guys are getting good results in x-cab s-dimes with an up-firing sub/ side firing port design. So, I'm thinking I might give this a try. vehicle: 03 chev s-10 subwoofer: RE Audio SEx 15 (dual 4 ohm coils) Amplifier: JBL GTO 601 (600 watts @ 2 ohms) Looking at doing an enclosure out of .75" MDF Outside measurements: 15" height * 40" width * 16" depth Slot port: 14.5" wide * 3" high (port area of 43.5") * 23.5" long (tuning ~33.5 Hz) Net enclosure volume: 3.6 ft^3 Big question I have is, will 43.5" of port area be enough, or do I need more to prevent terrible port noise? Thanks for your opinions in advanc…

Hey guys im considering getting this passive radiator for my Fi BL12 TC Sounds VMP 15" The reason is i dont have room to port an enclosure underseat but i may be able to fit this. If i decide to go this route im going to design a port for the enclosure and then calculate the mass of air in that port to add the the PR, is this correct? I just want to run this idea by you guys since you all know so much

I don't really want to order this stuff and have to wait for it so i wonder if i be alright using some things just lyin around the house? The space i got to fill isn't too large really. IT's about 3-4" wide and about 8" tall and the deeper the better. I was thinkin about stuffing all kinds of shirts that i dont wear anymore in there.. I'm sealing a wall and i gots to seal around a window and i'm not spraying foam on my glass so thick material is the only option. You think shirts or blanket sheets will work fine?.... then i'll just spray foam on this to complete the seal...

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…

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

well just picked up a 18 btl just wondering what everybody on here suggest for a box all opinions welcome. Will be running a hifonics cyclops xxv for power. thanks in advance.

I'm planning on building a wall in my Lumina, I'm in need of a design. My set up will consist of 1 DC power engineering 270 amp alternator,~3 deka intemidators, 2 Audioque HDC3 18's in a 12 Cuft wall with a removable port tuned to 38 for daily and higher for comp. Lastly to power the subs a Sundown Audio 3000d. here are some specs with pictures included. Pictures w/ measurements Height: 37 in Width: 29 in and at the curve 38 in from the hump to the roof is 38 in 33 in from rear deck to seats 46 in from bottom of the floor to the ceiling 55 inch from door to door More pictures (P.S. I know my carpet is dirty. M5 already made it apparent)

I plan on competing SQ this year. I'm not sure on what pics I need for the presentation. Can somone give me some tips to get me started? Thanks
