SPL & SQ / Fabrication

All my experience in audio comes with sealed enclosures, even so, after having visited this site, I feel like my past work was rather half assed and mindless. This is what I have so far: I am planning on using two soundsplinter rli10s, and I could be perfectly content with keep it sealed, but I want to try my hand at porting and perhaps learn something new. I have been trying to talk to a few people about porting this enclosure, but I am not really getting any good information, and I am also reluctant to trust any information from WinISD. From what I understand, that program can be slightly flawed. My box is 1.08 cubic feet after all displacements are taken into account…

I only get static when both sets of rca's are plugged into my 4 channel avionix amp. When i have ony 1 set of rca in the amp it is clear (Static-free). I tested this on both sides of the amp and the same thing happens regardless if i have the rear rca installed or front rca installed or vice versa. ANy ideas?

its a box for two Fi 15 ssd's. the dimensions i have are 42"w X 20"h X 22"D total of 8.8cu.ft and total of around 8.5cu.ft with sub displacement. and a port 8"w X 8"h X 13"d would tune it to 32hz. thats the calculations i came up with,i just want to double check before i go cutting up mdf.

I'm in need of help finding someone who can make me a second alternator bracket for my 2005 ford escape 3.0l motor I've been in search for months now and can't seem to find anything for this vehicle.

I got 4th in 139.9 after busting out against alpine. But I got to take Bill out in round 1 so that made my day 1-6th place finishers in 139.9 all qualified with a perfect score My scores for the day, 145.0 windows up 145.8 windows down 146.6 drivers down All on music (jeezy, ~40hz) Thanks DC for making a lvl 4 strong enough to hold 2800w rms -Derw

im currently evaluating a couple of designs for my setup and this is one of them i would love to get as much feedback on this as possible. it will be in a 95 single cab dodge ram.

ok so i have built a few boxes now always using slot port and designing them myself and what not... but slot port always takes alot of space up... i am thinking of using aero ports.... now but it is hard to get exact sqin of port that i want... anyway my q is they displace less air correct... and if so i know it depends on length but is it a dramatic amount thnx trunk cars sukk

The box is for a pair of DC Level 4 18's in the back of a 2007 Suburban with all seats in, including the third row.I have the following for outer dimensions to work with: 27 x 49 x27 Now my drawing shows a height of 26 1/2, but I'm only counting the height at 25 3/4 in the Box Calc program because the top board was double baffled. I'm seeing a box tuning at 33hz. Here is my other design, this one is pretty much the same as the first except for both subs and port firing up. What do you guys think? Box Design: I think I still like the whole port and subs up design better. My current box is a dual chambered double slot ported box. Each chambered tunned to 32hz. Has anyone…

ok XTRemeasures, I think i'll deff be down next weekend for this event you where talking about, could you post up the details for me, and i'll call ya when I get there. thanks in advnace. Also, who else is gonna be in attendence?

Planing on tuning it to almost 42 hz. This will be a competition box for my 04 jeep liberty. Subs up port back left. My question is what type of sq foot should i use for this box. Alpine's site says use around 2.5^2 per sub in a ported enclosure. Also if it matters im planning on running these off of a Sundown SAZ 2500d

Is the opening of a slot port supposed to be on the face of the enclosure, same direction as the sub is facing? All the boxes I have seen have them there...is that the requirement, or, just common way to build it?

Hi everyone, first time poster on this forum. Posting all the way from Australia. Okay, So I'm in the planning stage for a system in the new car, and I've just started doing up some rough design/placement ideas on Inventor, when I ran in to a problem. I'm designing this for a Fi Q12 ported, and I know the recommended enclosure sizes given by Fi of 1.8-2.5 cf @ 28-33Hz. However, that is quite a large margin of variation for a recommended enclosure volume (0.7 cf and 5Hz tuning frequency can affect the sound a fair bit). As I'm not a massive fan of guessing/speculating about the best enclosure volume, I decided to pull out the calculator and the old loudspeaker design c…

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 got bored and decided to draw this up, its right around 2.5 cubes @ 35 hz. gonna be for two 10's ( AQ SDC2.5's) Its gonna go in my chevy std. cab. Any comments or suggestions?

My friend just got his first non kicker sub and he got a fi bl 15 he is putting it in the back of his Chevy extended cab he can make it about 15-18 inches deep 17 inches high and can be up to around 50 inches long he wants his box about 5 cubic feet and 32 htz can anyone help with a design

i am trying to build a box for 4 of my kicker cvx 15's. i called kicker and they recommending using separate 3.5 cub. ft chambers tuned to 38 hz. since this is gonna be my first box build is there an easier less way to build the box without having 4 separate chambers? maybe 2 subs per port or all 4 with one port. it is going inside the car. maybe even a wall design. my available space is 32x56x36.

Vehicle : 93 xj Location in the vehicle: rear cargo area Space available (Length x Width x Height): 42x32x20 Subwoofer make and model: ssa zcon d2 Subwoofer Size:12 Number of Subwoofers: 1 Type of Port (Kerfed, Slot, Aero, etc.): curious... What type of music do you like?: rap, c-wordry, dub, slowed... Is your music daily or spl? day music with spl based qualities Tuning Freq (Hz): curious... Volume : not sure yet... Questions: So, I am buying a zcon soon, and want to build a different style of enlosure, but lack integral skills in the design and math part of things. I could have one custom made by local shop, but I want built not bought. I want it to be my work, not som…

Okay so, I got my designs, and lowes completly messed up all the cuts, so I have to take it back and complain and hope that they give me new wood or something..... So in the meantime, I just "sketched" up this box. Here is a pic here is the google sketchup file http://files.filefront.com/fibtl18skp/;13080625;/fileinfo.html for anyone who wants it Let me know what you all think! (I didn't make up the specs for this, a help from another member on this site did, I just drew it)

Yup, I think it's worthy of a new thread. Tomorrow I have to lug this PC out into the hot muggy humidity again, cuz as if it wasn't enough that the guy made me realize I could/should get so much more out of my tweeters with his Memphis 5.25 coaxials shredding my drums, but he went to bragging that his Anarchys and/or SA pro 8's could prolly do well in the 129dB class. So for the fun of it I went out and dropped the PXA-H701's from 50Hz to 25Hz, still 30dB/oct, left the Kicker at 50Hz 12dB/oct.... cuz I keep thinking about how the REW sweeps showed a cliff dive at 125Hz peaking again at 65Hz for another dive. I can turn them up to the same volume with no clipping, no excur…

I found measurements for an enclosure for my 2 12 inch pioneer champ pros tsw3002d4. The box is tuned to 33 hz. I was just curious as to whether that would be good for my subs or too low? The amp I am using is a hifionics zeus 3000 watt zrx3000.1d. This will be my first box build so I want to be as clear as possible. I used RE audio calculator if that is any good.

I need to make a snorkel for my truck so i need to build a fiberglass tube that goes through my fender and up the A pillar. how should i go about building a fiberglass tube in this manor? also what is the customary way to attach such a thing to the outside of the vehicle? thanks.

hey guys, I have recently purchased a 2006 subaru legacy 2.5i. my previous car i had 2 12 inch gcons on a sundown 1500 amp, a 6 cubic foot box that i sealed into the cabin. was wondering what would be effected if i were to seal the box instead of port it and still reverse the subs facing the cabin. so run a 3 cubic foot box sealed off from the trunk with the subs facing the cabin. i just am wondering if this would work. or if it would sound like shit. haha. i have the box designed to fit into the trunk so i can seal it off. I am trying to save space (i snowboard in the winter) roof racks can only carry boards. id have more than half the trunk left with the box ive designe…

sub in question here is a xcon 15 this is my first time using this or any sub enclosure design software when i put in the qts, qms and qes parameters this is what happens: Help a noob out!

This is what happens when you get wood cut at home depot. I got all my cuts at home depot and some are 1/16 to short. they wasnt using the regular saw. i was wondering can i use some sealer tape for the cracks?

snoopdan uses pink panther insulation to seal around his box so it acts like a wall in his cherokee. I just got done building my box in my scion tc with 4 15s and i need to seal around it so it can act like a wall. I was gonna use pink panther but have 2nd thoughts because it states that it's purely a thermal barrier, not acoustic barrier. Is there any methods u guys use or can persuade me with facts as to continue to go with pink panther insulation or is there a better method?
