SPL & SQ / Fabrication

Ok, I tried to do some research about tuning and port area, so I didn't have to make a thread. I read a thread on smd and they were saying 10sqin per cube was better for low tuning and then others were saying other things like more the better so I don't know which is right. A lot of misleading information out there!! Much rather ask here and know I'm getting the right answer lol I'm most likely going to be ask pro-rabbit for a design once I am sure of my measurements,It'd be nice to know exactly what it should be, so I can expand my knowledge. I would like to know for my system specifically, but also in general. EQUIPMENT: Subs: 2 SSA Zcon 12s Amp: 2 Crescendo BC2000s(won…

I need a sheet of hard plastic like ABS to use in a bunch of places in my car. Does anybody know where to get anything close to that? I haven't really done any research so if anybody could point me in the right direction I would really appreciate it.

not sure if this is the right spot but anyways any of you guys try to fit 1 or 2 of these under the seat of a pick up before? the truck actually is a 2006 F 150 super cab.....dont get it confused with a super crew. Im gonna try and figure out the box today and i just thought of using these i was going to run two 8's ported off 1 SAZ 1500D. im also considering two RE 8's too but i figured the AA would handle the power better than the RE's. Anways the other question i have is how much room is good to have between the cone and the floor of the truck. cuz i know i should beable to fit the RE's in there but the AA's are going to be tight as they are a bit taller in depth t…

I'm trying to figure out an enclosure configuration for 3 SA-10s, just not sure which way to go. Was looking at doing a downfire enclosure with an aeroport(s) firing to the side,. Just curious if there is any drawbacks to something like this. I like the idea of it being less visible, as well being a little more protected from the elements if the top is down. If it's a terrible idea, I'm all ears for better options. Thanks

Hello again! Wanted to have a quick poll/question. So do most of you use MDF or HDPE for door speaker applications? I know some people won't touch any plastic for audio, but some would swear by some of the high quality stuff like HDPE. Your guy's votes/opinions?

As many boxes as I built, my mind went blank today. I am trying to build a 30in long port with 1 bend. Do I measure in the center of the corner or along the inside port walls? Someone help a mind blank guy out?!

I've always designed the box with the port on the side, but now I need it in the middle (using 2 subs). I do know that when the port splits off the port width gets halved, but is the whole length of the port mean that each side is the port length? Let's say I have a box that is 6" wide and 30" long. When it splits off each side will have a width of 3", but does each side equal 30" long? Someone also told me that you add half of the width of the port to each side of the port length. So each length would actually be 33" long. I don't know why that would work though. When I design boxes I use torres and there's a box that says "# of common port walls". I put 2 in there, …

So I will be ordering an OA-12v2 D4 very soon after selling my current system (Upgrading from a Fosgate Punch P2 12, 2011 model). I have a Rockford Prime P500-1d to work with, so the sub will see just over 500 watts. I have read in many places that the more power, the smaller that the box can be, and the less power, the larger you can build the box... generally. So I was thinking of doing a 2.5 cuft enclosure for the OA, on the 500w. It will be going in the trunk of my 2000 Civic sedan, most likely sub back, port side. Does this sound appropriate? Is there another way I should approach this? The box will be tuned to 30Hz via 4" aeroport. Thank you for any help, and I apol…

trying to decide on 2 different setups and basically, if you like loud (40hz area) but also don't wanna lose that low rumble in the 29-32hz area, what setup would be ideal? all ran off of a 5,000w amp 3 12" Fi Qs(BP option mandatory) Sealed in 4 cubes. 3 10" AQ-HDC3s ported at 37hz. I know that the 10s are louder but i have never done a setup of this magnitude and am wanting to know really, for someone who may have done something this loud before, what is your opinion on this? I know the sealed setup, i can get my lows just fine, will not be as loud as the 10s but is it gonna be very noticeable? Basically, i can give you a scenario- If i set SSF to let's say to start roll…

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…

ok so im ordering a z15 hopefully tomorrow if my dam taxes show up and i would like to have the box built and bolted in my car b4 the sub arrives. now my question is should i go sealed or ported to move a ton of air and have alot of feel to it? btw its going in the backseat of a 76 caprice. and the next thing how can i get box dimension? sealed wouldnt be hard to figuer out but if i should go ported ill need some assistance. recomended sealed is 2.5 cubed and ported is 3.5 cubed tuned to 30 hz. thanx in advance for any help

Designing a new enclosure for a Fi Q18. I want to be sure that sub placement would not cause any issues with unloading thru the port or odd loading issues off the port wall. It is only a single sub, so I dont believe the loading off the port wall would be an issue. Here is a quick sketch up of the enclosure. The guide mark is the mounting depth, and is approx 4" from the back plate to the port wall. I would prefer center placement just for aesthetics but functionally I believe the position closest to the exterior port vent and above the port wall may be the best bet. Thanks for any insight

has anyone here tried to build an 8th order bandpass. i ask because i have had decent succeswith the 4th and 6th orders but now im thinking of trying a 8th order just for spl and was wondering if anyone had any experience building one

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…

It's about 7.4 ft^3 with a 13x6.5" port. Two 12" type r's are going in and will be running at 1000wrms. EDIT: What would be best to tune this box at? I'm doing daily and want it to sound good, not just loud. EDIT 2: Listen to mainly rap.

what you guys suggest? i mostly hear 2.5 net for the 12. power is 2 kx1200.1's strapped, so at least a good 2400w rms. ive already taken all the measurments and everything, this is about 3.8 gross, so i may shorten it a little, leaving me more room for amps on the top. port- what should i tune to? its for rap music. slot? aero? heres sorta what its gonna look like. the yellow will be double 3/4"

I am new here and need some help, so if you could help me, thanks in advance. I have a 96 Mitsubishi Eclipse (with a sun roof) and 2 12" audiobahn aw1200q subs. I have a lanzar 4000 watt amp for the subs and a stinger battery and batcap 800 as well as 0 gauge wiring all around. can you help me with a setup that will "pound" right now I am hitting a 141.xx thanks you!

Hey, this is what i got: 1x pioneer sub ts-w3002d4 @2ohms=1000rms QCA3500D amp; 2ohm=1750watts rms enclosure: 20"x16"x13" port size: 2"x11.5" everything on my car is stock and i think my amp is putting out a little less than what is rated performance wise, i dont think that my sub is performing like it should, my excursion is nothing compared to what I see on you tube and im not sure if it is because of my enclosure. I know that I can get better power if i upgrade wiring but I think I should be getting more out of what I already have. I want to try a different box, does anyone have any suggestions on sizez and I dont know much about tuning but im not getting high end …

Today im going to build my 1st box for the fully loaded fi bl 12in. Im going to be using 3/4in thick mdf fiber board. Would i have to use braces to hold the box, its just one 12in, and also i have a Sundown sae 1200d amp. Is it capable of producing 1500watts rms. What would you have to adjust the amp to to have a good, loud sound? I have a Stinger amp kit 0 gague, and extra 25 feet of 0 gauge wire for the big # upgrade, and i also have a kinetic battery the khc 1600. Just recentley my friend got his system installed. He has the same equipment as i do, but he has the FI Q. Let me tell you, it is LOUD AS HELL, For just one 12inch... omg i could barely breath. To be honest i…

Hey everyone. I've got a 99 dodge 1500 regular cab. I built a box to go behind the seats that was about 2.4 cubes and had a 3" aero port, loaded with a Fi Bl 12. I resently bought a DP 12 and it is quite a bit louder than my Fi, but I know it can get louder. I'm building a complete fiberglass box to replace this one, and it will have the same basic layout, but I'm putting in a bigger port. I've got a 4" and a 6" aero port. So my question is, which would be a better combo: DP with 4" aero port, or DP with 6" aero port? I can possibly fit either one, but I want to know which one would be better for me. My music style is rap just because of the bass, and I LOVE the lows, and…

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

Would there be any negative effects from running all-thread though the back of my box directly into the cab of my truck. The back wall of my truck is already threaded and I could strongly secure the box this way. But Im wondering over time will I get leaks or put to much stress on the MDF. I will be using 1in MDF more than likely. I would seal it and also use a 1/2in rubber mat between the box and back wall and floor to help with sound deadening and vibration. I also will be using the back seat metal bracket to mount the floor to, I can also run allthread through box and floor threaded directly to the metal brackets. This will be a semi wall and will probably make beauty …
