SPL & SQ / Fabrication

I have a 97' Thunderbird that Im doing now. I wanted either a pair of Fi BTL12s or Fi BL15s. I want the BL15s because I would save a lil money on power and can be used in other areas such as the build, elec system, etc..... But the enclosure size needed is kinda on the large size for my trunk. But I can fit them in there if I angle the baffle and use 2-6" aero ports. My real question is I was reading on another forum that a guy with a mustang (which is basically the same trunk as mine) had success with his subs facing forward and his aeros on the side. He said that subs back/port side was the loudest on the meter but subs forward/port side was the loudest to ear. Has anyb…

I need help building a wall in my 95 lumina, i don't want to pay 1 grand for a wall that i could build myself. Does anyone near Kansas city missouri know how to build walls? and willing to help a fellow SSA member?

I was thinking about to the standard square ports, but last night I thought about doing one, maybe two, larger round ports using PVC. Has anyone tried this. I was thinking something like 8" diameter ports, maybe two of them. Since it is going in a blowthrough, is it also okay to extend the ports out a little, maybe almost into the blowthrough to ensure more pressure from the port goes directly into the cabin of the truck.

Does anyone know where I can buy a copy of the USACI SQ disc with Hotel California? Or if someone can burn me a copy, I'd be willing to pay...of course.

i got 2 15 fi q i got a subwoofer box with the front slanted.. will it make a difference in sound?? i got 2.3cubic feet per sub on the box.. on a 2005 nissan altima running a soundstream rubicon 2500 with kinetik hc600 and rockford fosgate 0 gauge amp kit.. the box is on its way and im worried about will the slant make a sound difference will it decrease the sound quality?? ill be facing the subs towards the trunk away from me. well its in the building process..i can send an email and tell the builder to make it square if it makes a difference..

Ok so im going to build a box for my new setup and im still not getting this port thing. Alright so the dimensions i want the box to be is. Height 20, Width 49, Length 50. And tuned to 32 hz.

I think this is the right place to put this. Ok, I want loud, but not "boomy" bass. Is that possible??? I will be pushing my 2 RL-p 15's with an A2400DB Power Acoustik amp (1800w rms @1ohm). Would my best bet be to go with a sealed box?? Or should I go with a ported one?? I listen to hiphop, rock, and everything in between. I would like to have a good LSQ system. Any info you can give me would be great. Thx, Victor. B) P.S. this system is going into a s10 xcab. So the subs will be inside with me not in a trunk.

can anyone please help me design a box max dim 44x22x22 going to be in the trunk of a 1997 towncar

I am getting ready to make a box and need to know two things. I am building a box for a nightshade 12 and I got an aeroport. The box is going to be sub up port on the side 1) Can the port be inside like old times? The only reason I am asking is all I see nowadays with aeroports is crx style with ports out of box. Will I lose db's by putting port in instead of out? 2) If so how many cubes roughly would it take up? Port will be 15.5 inches long and its a 4 inch aeroport. I am trying to see what I need to make dimensions of box if port is in instead of out. I just want the best possible setup I can get for what equipment I have.

So I'm good at building enclosures.....calculating ported enclosures? Not so much. I've just bought a new tow vehicle and using some budget equipment to put a nice setup in it. These are new items I've had laying around to put into a project car I'm building that won't be finished for a while. Vehicle : 2004 Escalade ESV (Suburban sized one) Location in the vehicle: Rear hatch, against the 3rd row. Want to keep some cargo room Space available (Length x Width x Height): 46" wide is set. 16" deep is set. The height is my variable. 20" is maximum. All dimensions are internal. Subwoofer make and model: Subwoofers are JBL GTO 4 ohm models Subwoofer Size: 12" …

I gotta go buy another sheet of mdf, dam thats 44bux...22$ each I have my friends lil d-snap camera, but he didnt giv me the usb connector to get the pics off of the camera hopefully i'll get it 2ma.. and hopefully i'll be finished wt the box by then also. now i still gotta order the subs

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?

I'm going to be building a box for my friends Ram. Aero ports seem to be the only way to port this box but I've never used them before so im looking for a little help. Box will be going under the rear seat. The sub is a JL 10v3v3 Box will be about 1.33ft after sub displacement Tricky thing is I only have about 3 inches of height for the areo.(Rectangle box with wells on the bottom) The Rectangle part of the box will be W54.5-D13.5-H3 JL Recommends 32Hz 84.7 Slot Port Area

Hey, i currently have my box in about 1.6 cubes to low 30's, and Mike told me that 2cubes net at 34 would give me more output. I want to make sure i won't lose SQ, but i might give this a try. Will i gain much output with this change? Will i still have excellent SQ? I searched a ton on here and caraudio.com and read up on ports, square inches of port area, etc, and i used various calculators. I used the calc on maximacar.com, which is the best i have seen. The box dimensions are: 24x14.5x15 with a 4 inch by 11" port. The calculator takes into account woofer displacement and displacement of the port, and it comes out to 2.29gross, and 2.06 net. With the box being 1…

I have an re sx15d4 in a box that is 2.9 cu ft gross w/2 3" wide 10" long aero ports. I will be running an saz1500d @2 ohms into this sub. I want the best sq I can get from this sub. So I'm looking for box recommendations. Right now I'm looking at building a 4.2 cu ft box tuned to 34 hertz with a slot port facing the back of my jeep and the sub firing up. I used the box calculator to design the box.

Is there a major sound difference for a 12" from 2.30 Cu. Ft. to 2.50 Cu. Ft.??

I need help with a box spec for my 2 Sundown Audio SA-15s. Its going into a Izusu Rodeo. My goal is to hit over 150db. The box needs to be 6 to 8 cubic feet, port tuned to 35hz and max width is 41". I looking for a box that i can use as a daily driver and for competitions. I would appreciate the help.

so, im currently redesigning yet another enclosure for my home theater mains. was wondering what the effects, pros, cons are on port placement. using a 3 inch round port. a 6.5 and a 1 inch tweeter. so top near tweeter or on bottom below mid or just rear firing? pros cons? im thinking port on bottom with about 2 inches of separation between port and mid.

how small of a port tube can i get away with for a 1 cuft box? going to put a ssa dcon in it.

can someone tell me what a t-line enclosure is and whats the advantage

I got a cut sheet from skar audio, and i want to know others opinions on it. Ive tried to draw it up on paper to visualize, and ive done some calculations to help someone who knows how to use the info. Its for a friend so i don't wanna waste his cash on a shit design. Ok so he has a 97 Jeep grand cherokee. 90a alternator, I did the big 3 for him in some 4 gauge stinger pro i had laying around, and he had already bought a Rockford amp kit 4 gauge also...pretty nice wire. Ok the max dims are 36" wide, 36"deep and 30"tall, this leaves plenty space for the port to breath either up our back..The subwoofer is a skar audio ivx15 V1. Its a d2 coil. Here's spec off woofersetc.co…

I have a 97 accord sedan, I running a alpine hu I have 3 JBl BP series amps. the 80.4 for my highs and Im running the BP 1200.1 per sub. As for Subs, I have the MKII 12's Brahma's (2) in a 1.75 cubic feet box I think tuned an 30hz. I don't think it hits hard enough I haven't had it tested yet. Im looking for some suggestions for a new setup to get a deeper and harder bang. Could someone help with some ideas, even if I have to use the whole trunk im fine with it

I know some cars are louder facing back and some facing foward sealed from the trunk. i was wondering if anyone knew what was best for an 04 hyundai sonata? i was looking at a 15in or an 18in with between 3000-3500 watts depending on which amp i deicide on. looking for loud daily.reason for one sub is cost. thanks alot.

Like title says guys i have these subs laying around i dont have dimensions as the car is my gfs and she would like to have some bass in there so instead of having them collect dust and her hatch looks small then might as well throw them in there so im looking for the box to be tuned to 32hz. Mainly listen to rap/hip hop and some light rock. Forgot what else to put in this been a while since i done this alright hope to hear from some knowledgeable people here
