SPL & SQ / Fabrication

yup, the shit's still in the ceiling and it's gonna stay there. if you need to hear the drummer strait ahead and back 7 feet, the back up singer come 3 feet deep from 7 feet from your right, lead guitar and vocalist strait ahead yadda yadda... if you're all about staging, imaging, using time delay, phase, and EQ.... GOOD FOR YOU! I like it loud and clear. it is loud and clear. I like a ton of midbass and a ton of high treble and easy on the low treble and easy on the midrange. So this thing has come a long way, I now have: Alpine IVA-W505 touch screen DVD player so that I can use the touch screen to control the digital Alpine PXA-H701 crossover/processor. I have (2) Kick…

its for to 10's

So im making a thread that may help people in the future on different enclosures for different applications. So what are the physical differences in an spl enclosure compared to a daily driver enclosure or sq enclosure? What separates the two into different catagories? for example does a box that is bigger and tuned high make it a spl enclosure or vise versa? Thanks in advance for your expertize.

Only one sub rite now the other one will be in on Tuesday. Box is 7.1 cubes tuned @ 30hz Hit 144.4 sealed up at 43hz without much testing. 146.7 outlaw.

i sold my crx i coudnt keep fixing it anymore my transmission went out i have bought the 18 xcon when they were on sale used for $300 and i now financed a 2003 acura cl!!! i miss my rex and now i cant use my 18 xcon i need help deciding new system i dont wanna tear my new car up but i want it to be loud and have some sq without tearin it up

I was wondering if I could use metal L brackets in the inside or outside the sub box the reduce the vibration or flex? I saw the wood ones, but those take space inside the box and my box is quite small and I don't wanted any more smaller.

So here it goes I seen a thread where someone used two of these for this but I have lost it and cannot find it. I am interested in doing one of these setups in a sunfire. I have a15" soundsplinter Rlp but don't want to take up the trunk with a large enclosure. The IB setup would leave trunk space and be pretty cheap as far as the woofers go. I have a sundown 1500 SAZ to power them and know I would have to be vergil with gain settings......anyway any input is much appreciated. I have read the thread from Onebadmonte twice now and I think this should work good just looking for extra info before I order the woofers.

i need a box build for my sa-10's

Want your guys opinion on this. On my HHR wall, Im thinking of covering the inside of the ported chamber in suede as opposed to painting it. Would this affect sound or performance any?

I am about to start a build log (finally) but I want to get some final suggestion(s) on my Front stage. It's going in a 1998 Honda Civic 2-door coupe. Big 3 in 1/0. 170 amp alt. XS Power D680 and D5100R (front)-1/0. 4 gauge to amps from D680 that is in the rear. Kenwood 942HD head unit, I use the cross-over controls on the head unit. Previous setup...Kenwoods 5 1/4 co-axials...Front....Pioneer 6X9's in rear. (in car when I brought it) 2 ch 2 ohm (200x2) on the Sundown 125.2 I didn't like it...sounded OK (on mainly Pop and Hip hop) , the rear was always louder than the front stage (which was irritating at times). It wasn't very balanced. I listen to all music Jazz…

Hey all.Ive decidied since my trunk is so small im going to do what ive always wanted to do.Wall my car.I have a 2001 galant and was wondering if it would be worth the money to wall it.I will use my 2 15" american bass xfl subs and my planet audio bb2 2400rms.I have a friend thats saying it wouldnt be worth walling because its not a hatchback car.So is he correct or would it be worth it? I will do some competing but I mainly want to be as louad as possible on music.

So after seeing the new box I built for my future DCON's (ordered over two weeks ago) a freind of mine has recruited me to build him a box for a single old school (2001) Kicker c12vr. He wants a SQ build and could care less about output. The only problem I am seeing is that I can'ft find any specs on the sub. The manual I found for it is a little light on the T/S parameters so winISD isn't too helpful. So my question is, If I run a standard 2cuft box tuned to 32hz(seems to be a standard), would that have a somewhat flat responce curve(ignoring cabin gain and all that)? It seems to be a tried and proven tuning so If I strive for that, and being that he is new into car aud…

I have 4 sa-15s im needing a box for. They will be going in a 98 gmc jimmy. The dimensions I have to work with are 36wx22hx40d. I'd like to do subs up port back. oh and they;ll be on around 2000rms for the time being until i can get a saz3500. Thanks in advance

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

Time for a new box and im gonna need alittle help. Not really good at box design so thats where yall come in handy. I have two of the new 15" BTLs and i know the box from my x-cons are holding me back at this point. Im figuring i wanna go with 8-9cuft tuned to 34 or 35hz. Port area is whatever it needs to be for a good mix of daily and spl. Im assuming 100-125 for port area will do the trick. Needless to say if you can design me a box and the cut sheets id much appreciate it.

well i had the having the box where the backseats are located at, since i barley got the car and not ready for a wall i had this thoughed in my idea has it been done before? how does it sound? any mechincal noise coming from the woofer you think? idk if i worded it correctly. its ethier my recone them to 18's or recone them to 15's i currently have 2 10's dc audio xl woofers any input you guys? no idea if its done before to be honest, is my idea a complete fail or another way to feed my goal of getting louder any input will be helpful

anyone ever used this box calculator before? box calculator im having trouble figuring out the port as on my cut sheet it says on a 30x17x9.5 box= 2.05 cubes. tuned to 32.34 hz that my top/bottom port is a 2"x 1.65" cut? i just dont understand this, as this number seems way too small to be an actual port. it is a 3 common wall port as well. any help would be greatly appreciated!

Wassup fellas I built a box for a 18 btl but went with an aq hdc3 18 until Christmas. It is 8 ft3 at 30 hz. My problem is I think this box it too big for the hdc because anything above 40 hz sounds like trash but is a low end monster! also from 25 hz to 40 hz the excursion is the same! It's like the box is too big and it's acting like IB. Can some one help me out ha I want an ok topend instead of the junk I have know! Thanks

i am doing a 4th order in my grand cherokee and was wondering what would be a good sealed chamber and ported chamber. Equipment i have right now: 2 18" DC lvl5's 2 Sundown 4500d's 1 300 amp powermasters alt 8 3100's

Birch is looking a lot better than MDF atleast in Miami humidity for a 2002 Chevy Avalanche midgate enclosure. But I need help on the best specs to get the most out of 2 Nightshade 15's sub box. I'm going to coat it with spray on Truck bed liner to protect it. Sundown recommends a 2^3 enclosure but I just wanted any tips and the best layout that's worked for you all.

This is going in an RX8. Looking for a fairly good ground pounder with the ability to upgrade to 4 SA8's in the near future. Not sure This design has enough port area. Don't do too many ported boxes and would like to make sure before I waste the time building. Will be powered by a Sundown 2000D. Link to pic of enclosure I had worked up.:

I need advice with my current and future setups. Please anyone with lanzar opti1535d experience, please speak up! I currenly have it in a 4.35 cube net Atrend 15lsv enclosure tuned to 36 hz with 48.5 sq in of port area. Its in my ext cab sonoma sub firing up behind drivers seat and port firing to the driver side at the base of the b pillar. Its powered by a Lanzar HTG2600d at 0.6 ohm. Here is the odd part. It metered a 139.9 at 44 hz and when I inverted the sub so the basket/motor was exposed, I then metered a 141.2 at 44 hz. For some reason I was thinking when I metered again I hit a 142.1 but that's likely just wishful thinking. Apart from the airspace change from inve…

I recently bought 2 RE AUDIO SXX 12" woofers and plan to build the enclosure (vented) by myself (first time in my life). Since the manufactorer's web site only provides a box calculator for one woofer, can somebody kindly give me some advice on dual woofer enclosure and port measurement? In order for the box to fit in the trunck, the size constraints are: Length < 35", Height < 16.5". I prefer SQ over SPL and hope the bass hit as hard as they can. Thanks so much! The T/S parameters are listed below and more info. can be found on http://www.reaudio.com/woofers.php#goto_sxx Qes: 0.32 (Electrical Q value) Qms: 4.4 (Mechanical Q value) Qts: 0.30 (Total Speaker Q value)…

My buddy wanted to go from 2 12s to 1 12 in a sealed so I built him a box for free and he gave some cheapo 12" sub as a thanks. I would like to build a 4th order since I never have and see how loud I can get this guy for shits and giggles. Problem is I don't know where to start on designing one.
