SPL & SQ / Fabrication

I've been trying to decide if I want a single Din, Double Din, or possibly Car PC in my truck but I think the question can really only be answered after I decide if I want to go 3-way or 2-way Active. I have now currently installed one 2-Way Active setup ran by an 880PRS so that is my extent to an active setup. I have been told to do a 3-way I may have to go with a robust 7 instead of an 8 but would really prefer squeezing an 8 even if that means a custom door pod that I have seen made. I have no problem with using the kicks or glassing as well So I'm really looking for some Pro's and Con's between 2-Way and 3-way. The more I think the more I really just want to go all ou…

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...

so in a month or 2 i will be starting on my rebuild to run 2 old style XXX15's, 2 sundown saz-1500d's and other goodies i haven't decided yet(sound deading, comps and such). well, what my plan is on running these is to seal my trunk off from the cabin. for the box i want to forward fire it along with the port. from where i see it the baffle will sit 2-3 inches from the rear seat opening. the trunk space i have available is 40" wide, 17" tall, and about 29" deep. though for the size enclosure I'm going for about 6cu before displacement. i believe i have about 8-9cu before displacement total. here is a quick sketch i drew up on a graph paper. each cube length stands for 1" …

ok a couple of months ago i had woodlawn cabinetry build an ensclure for the subs that i thought i was going to use. well like a couple of weeks ago it arrived. and i really like it but the subs i had told him i was going to use i no longer want to use. so i figured that if the subs that i wind up using have a smaller displacement then the ones i was going to use then the port would be tuned a little lower and vise versa for bigger. now am i wrong and the ensclure is a 4.5 c^3 tuned to 33hz after displacement, common chambered for 2 12" ICONS. i want to use either 2 eclipse sw7200 or 2 12" aa aresanals powered by a sae1000d if u want to know.

hello im intrested in finding out where i can pick up ther softwear and hardwear to mesure sound on my laptop

its going in my 92 civic 4 door in the rear seat area i was thinking sub up port up...but curious to see what sub up port forward would be. only reason to go in that area is because we could barely get a 5 cube box in the trunk without beating some stuff in box is gonna be 6 cubes at 36hz anyone have an experience in a setup like this one? im not sure if its exactly legal in most comps because the box itself is gonna be over the window line unless they would consider it a wall?

I have built a few MDF sealed boxes and now im building something to fit underneath my truck seat so I'll have to use fiberglass AND it will be my first ported box. How do i go about building the baffle inside the box?

want good LSQ setup one si bm 12

Please, I know someone out there has a user manual for a 7949. Its all I want for x-mas. If you can just scan me the pages that refer to the units features and fubctions, setup and use. Thanks, Joe. P P.S. I've been searching everywhere forever now Thanks

Okay, from what ive read over the past few weeks ive decided that i want to go with an active frontstage. My DEH-7800MP is capable of this from what ive read. I plan on glassing the front doors to accept a well acoustically matched woofer and tweeter combo, i was hoping someone here could give me some suggestions on what woofer and tweeter to use so that i have little flatspots in my sound. Also for reference i hate harsh pingy tweeters, i don't particularly like all my highs to sound like crashing symbols! lol.... With switching to an active front stage this also means i will be completely losing my rear audio am i correct? Thats the only thing ive been confused about! T…

Hey, I have a set of TC-7 woofers. Right now the box its in is 40x12x12 with independent chambers. Aero port out each chamber to the side 3'' in diameter and 13'' long. Its to long for what I need it now. So I was thinking making it 36x14x14. That way it would be short enough and then I could have the ports fire forwards too. Sound good? But I know these were designed for large sealed apps. however i cant find specs for that. Could someone just give me some dimentions to make a box? I dont need 3d plans and all that. Just something l x w x h because I dont know how much airspace for sealed. Thanks

I had to get a pic on my cell, only camera I had at the time.

im wanting to do a build using a mach 5 audio spl 12,sundown audio saz-3000d combo the question is ,will this be a good candidate for a mass loaded enclosure,or t box on the street. im very impressed with what peter w. kulicki has done with two soundsplinter rl-i 8s but i want to understand the enclosure more because id much rather build myself.

I've been tryin to find a set that will owkr well together 2 way active.. I think I've come up with it. It will be run off a old sony mobile ES xm-5046 choices (madisound) mid - either SEAS ca18rnx or L18rnx(aluminum) both 7" tweet - SEAS 1" textile dome 27tffn I believe either of these would blend well and work together in a active 2 way.. What do you think?? or WOuld both mids work or would one choice be better?? Thanks, Joe. P

I came across these pics and was wondering if i could install some 8" mid-bass drivers in the same location. SQ/imagining is what i'm concerned about. Would it fly or should they be installed/positioned somewhere else?

I just got a set of Dynaudio 240GT (MSRP 975$). Before I install them I was would like the best option for imaging. Is there a rule of thumb to tweeter placement (the woofer is going in the stock door location) but the stock Toyota tundra tweeter placement is high in the door, IMO the only place worse is the top of the dash. I don

hi, i am new to the whole db drag thing? if thats even what it is called. how does these competitions work? i would imagine who ever had the most money would win... i mean its not like you can run and make your system louder or anything so since it is all just bought how is there a rightful winner if people just drop thousands and thousands of dollars? sorry it might sound stupid but i really dont understand.. vocab might help me too! thanks

i want to thank those of you who pointed out the error of the batterys as projectiles. there in a safe place under the amp rack now... back seat has been removed / replaced with a flipp up amp rack boxx placed for fitt

So, Ive been sitting here thinking about about what I should do. I'm wondering if Aeroports could be a viable solution.

pics of sundays show... more pics to come as they are e-mailed to me

I am running rookie sq in iasca. I was wondering if they have any rules in the sq division regarding vehicle builds. Specifically on caps, # of amps, wiring. I know they do for idbl, but I cant find anything on their website about sq builds. Thanks for any help.

after a little debate.. well not too much I've decided this has to be asked on this forum not ROE, where most consider SQ to be 2 pair of loud Pa speakers with no tweets I'll be running a set of tc 3hp motors w/ fi top ends.. dare I say Sealed, over there If I mentioned sealed I'd be crucified But on to the front stage. I have a alpine 7949 deck, and a sony xm5046(mobile es) so plenty of power for a nice front stage. First time running active. I usually run passive comp sets, which I have liked, but want to try my hand at active and see the differecne. I was considering a set of seas excels, with a lpg tweeter. What would you suggest that would sound as good and …

Hope this is the right section. Anyone in the Myrtle Beach/Conway area we are having a metering session Dec 8 at Carolina Audio in Conway. Call 843-455-9121 for info/directions. It's not a show or competition per-say because we won't have trophies or classes, and it's not really a show because there's no forms to fill out etc. Just stop by if you want to get metered on a Termlab for a good price. I hope I posted this in the right place because it was originally meant to be a competition, but we didn't get things really together in time and it's just not going to be big enough to have classes or trophies. Should be fun though, and get a nice offical T/L score without the l…
