SPL & SQ / Fabrication

I checked their forum and it seems to have died off.

Will using 2 ports work or will my tuning be off? I'm going to be running a Fi BTL 18 in a 6 cube box and want to run 2 ports, one firing left, and one firing right. as long as I have the same area and length would I be OK?

Hey quick question: if im looking for say 33hz from an areo port in a box 3 cubes how do i calculate it if i need two ports? heres the situation, i have box 3 cubes, want to run 4 inch ports. if i make one port its 7.4 inches long but i need more area than that.

For those of you that have pondered about getting a sponsorship and dont know how, or some of you that think you deserve one, here are a few helpful hints. #1 Accomplish something. Are you a nobody? Have they heard of you? Do you get noticed? #2 Sell yourself. If you cant sell yourself to them, how are you gonna sell their product? #3 Hold your tongue. I can guarantee you that there isnt one company out there that will sponsor a loudmouth s.o.b. that just makes negative scenes in public or on public forums. As a sposored competitor, you are representing the company. #4 Make a game plan. What comps are you going to? Do you show off your ride or just put a blanket…

Who will be there? Who is competing? What Orgs? I'll be in Street B, and street classes...

What is everyones definition of Sound Quality?

for thoes who have compeated in iasca or usac sq the question i have is where should the center of the stage be in the car. my personal prefrence is center of the steering wheel. i want to know if it should be right in front of you in front of the steering wheel or the center of the dash as you would need to look at the middle of the dash to imagin thats where the voices are coming from. which is the correct answer for competition i am runing 3way active and have time alignment to play with

looking to make a sealed enclosure for a 10" Infinity Kappa Perfect DVQ. the sub will be getting 400rms, just trying to get some confirmation on the dimensions of the box i should make based on my reading I should be looking for a box with about .8 cubic feet and using the mid-size insert. this look correct to everyone?

There used to be a few threads about things people were doing for SQ competition and some of the things each organization makes you have for max points in each category. I have a few questions about some of those things. I will be building based off of Usaci rules mainly because besides SBN (which offers Iasca as well) they have the most SQ comps in logical distances from me. My first question is about Processors, crossovers and EQ's. Do I need any of those three for max points or if I buy a HU that has all of those things built in will that count? If need be I will buy a cheaper HU and add something like the PPI-DCX730 as opposed to something like the Pioneer 880 or the…

Just starting an install journal here. Ive made most of the progress so far only having the trunk left to do after finishing up the install of the kicks/horns. Feel free to ask any questions. See sig. for other components in install. thats all fer now folks

Are there any SQ comps that are regularly in NC? I see that a lot of you SQ guys are from VA, where do you usually compete? Any local organizations or the like? I have never competed before, so I would appreciate it if someone could point me in the right direction. While I'm at it, what are the different SQ classes, and their requirements?

I'm more of an aspiring SPL guy, I don't know it all but I know a fair deal, regardless thats my personal focus. SQ is pretty much new to me, but I've got a guy with a 250 wanting a competitive SQ car a local shop is wanting to charge him out the rear in labor, I'm pretty confident I could do whatever needed to his truck. I'm just curious where to go with it. It sits now with Focal K2P doors, Focal Access rears, Alpine 4.150PDX amp, 2x12" Pioneer slims behind the rear seats powered by a PDX 600.1 and a JL 10" woofer in the center console powered by a JL 250.1 amp processed through a Kenwood DNX7100. He wants to move the K2P fronts to the rear and put focal utopia 3 ways …

So I'm looking for great demo songs to demonstrate the SQ installs out there! Songs that demonstrate depth, warmth, vocal isolation and instrumental detail.

so ive never really found a concrete answer to this, but for sq is a smaller or larger box better? my 15 fi q is in a 4^3 box it is very peaky down low, with kind of weak higher bass(by higher i mean 40-55 not like midbass), and fi says 2.8-4.0 is good. my brothers 12 fi q is in a 1.8/1.9 ^3 box and it says from 1.8-2.5 and it sounds amazing and even from LOWWWW to pretty high. im assuming the smallest recommended box is good for sq/evenness, and the largest is good for spl/peakiness? (I think i just made up words!) oh btw we are both tuned about the same(31 for me 32 for him)

i blended the sub down to fit in with the front stage and all i can hear is Loose Plastic panels Rattelling... s0o0o0o0o i have spent the last 2 nights re-doing the front doors & the thinggy in the headliner of the explorer... now all the Rattelling is behind me... Dammmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm it...

Sorry for the long post. I just bought a pair of Beals Bros 8" midbass drivers. I have no specs on them. I know you are probably saying to yourself, why would he buy them if he doesnt know anything about them. Well they were cheap and in great shape. Now on the the questions. As many of you know I am currently running a set of CDT HD-62 pushed by a Memphis 16-mc300 ~150x2@4ohm (depending on voltage) ~240x2@2ohm ( " " " ) Here is where the questions start. The Beals is 2 ohm nominal and the HDs are 4ohm. that would make the final load 6ohm for series ( not enough) or 1.3ohm for parallel ( too low). I have heard that lower impedance=more distorti…

im looking to buy a single 15" sub. im upgrading from 2 12" sony xplod sub so im sure whatever i pick is going to be a helluva upgrade but i still want to get the best bang for my buck and SQ. I looking at the Icon X and Fi Q and i wanted to know which would be louder and have better SQ. Also what box should i use sealed or ported Vehicle: 2008 Trailblazer LT with bose all the way around with a pioneer 3200 DVD indash headunit. THanks for all your feedback

Hello This is my first post here, I made a quick look ,it's interesting forum. However I want to ask about the specs of the SQ system and components? I have Car PC controlling my sound system which is: Car PC with Turtle beach and Creative Xmod USB sound cards. Rear - Infinity Reference 9613i 6"x9" 3-way car speakers Front - Infinity Kappa 63.7i 6-1/2" 3-way car speakers Amp - JBL CS60.4 4 Ch 240 Watt Full Range Amplifier what do I need to add/change to have SQ system? thanks

ill let the pics tell the story Many Thanks too Pierce Audio Products for the Comps

There was a video I got linked with a dude talking about his SQ comp car that had liquid cooled subs and amps and a reservoir in the back?

I don't want to upset anyone by saying I'm looking for an SQ setup if I'm actually looking for SPL, so I'm hoping someone can steer me in the right direction. I don't like mainstream rap music, and I don't ever plan on getting my setup metered or compete, so big dB numbers arent a concern. I listen to mostly underground hip hop and a little bit of rock, like 80s metallica/slayer, so hardly any of the songs I listen to dip into the really low frequency range. I'm running 2 audiobahns in a sealed box at about 2.7cf, and because of their design, they are incredibly cramped in my enclosure (go into WinISD and look up the Audiobahn AW1251 and let it select the optimum sealed b…

when you build a box with a square or round port, isnt it nearly impossible to stay within the 12-16 sq in of port area per cube rule? if so what is the rule for those? and when making a external port it is still the same length as if it would be internal correct, only it is on the outside...

is there any discernible difference between a square port and a circular port. I'm thinking about using a circular port tube from somewhere like Elemental designs. Mainly due in part to my lack of knowledge and how to build a ported enclosure.

Hello world, after much research and consideration I have finally decided to become an SSA consumer, I plan on buying a DCON series 15in to run with an Alpine MRP-M650. I plan on designing and building a custom ported enclosure for the sub, and this yields the question, what is the recommended volume for said enclosure? I know the SSA Store gives recommended box dimensions, and I have seen them for the DCON 12, but the fields are empty for the 15 D: Any help is appreciated. My guess would be somewhere around 3-4 cubes? But it's my first build so I feel like I need some reassurance. Thanks

Looking to get max spl in a trailbaler on a cadence a7hc. 1200 watts 1 ohm. I would like bass on all types of music. I have a 4" aero port laying around that i could use. Shoot me some ideas.
