SPL & SQ / Fabrication

So I decided to post this outside my build log to see if anyone might have any ideas to help me solve this issue. Equipment: SLS 8inch Midbass Drivers running 60hz - around 200 i think. Mounted in the doors w/ a pretty solid treatment of SDS MLV, CCF, and CLD. Shitty GM doors aside, its a pretty solid installation. kicker 250.2 bridge to each side Description of problem: Midbass from left side is quieter by rough 1/2 to the ear w/ an 80Hz sine wave tone (measures around 8dB lower IIRC). I don't remember there being a huge difference between left and right previously, though I didn't really touch the stereo for over a year. My understanding of …

So I decided to go with 2 12" Zcons D2s and I just wanted to see how well I did my box. I'm trying to learn how to design boxes better and wanted you guys to check it out. I want to have it in a ported box with port and subs front firing sealed off from the trunk of my 2012 Fusion. It will also have internal bracing with 45s. I have 2 Crescendo Bc2k and will have a H/O alt with a xs d3100 in the back. I want to have the port in the middle but I'm stuck with either doing a slot or aero port. The slot doesnt allow me to get as much room as the aero does obviously and also the aero allows me to tune lower. I would like to tune around 32 hz. Does that sound good for the zcon?…

Doing my sq setup, has 2 way components 125 watts each side. Looking for a good sq sub that goes loud but good quality under $300 I will upgrade later to something higher end. So far looking at the image dynamics idq10v3. (500 watts rms) also would a sub 500 watts rms overpower the front stage? From the comps? cheers any reviews on the idq would be good too

Ok so I sealed up the rear deck of my car, I have the MDF ready to be cut and set into place. My plan is to cut a 2" hole in the MDF to run my RCAs and power wire through, not sure how i can seal that up, any ideas? then im going to cut the speaker holes and mount the subs on the other side. that will be roughly 1" clearance from the back of my seat. I was going to try and find some rubber gasket at home depot to put around the MDF to seal it up to my seat opening surround. Does all of this sound like it will work out? Also im running a pair of boston acoustic g2 12s on my aq1200d for this setup

So i have been reading on how to calculate the tuning on a box with a kerf. What is a common kerf radius? and how to you cut the wood to become that radius? google isnt really helping me out here. i know there is some extremely good carpenters here that might be able to help me out. how deep do i cute to wood to cause a certain radius. i would like all the input you guys have on kerfing to help me figure it out completely. Thank you.

this is ALTONS post "FYI the box is EXACTLY in the middle of the specs Fi gives for the 12" Q's. Fi recommends 1.8 to 2.4cuft as optimal for a 12" Q, 3.6 to 4.8 for two obviously. If you notice the notes I specifically mention 4.2cuft NET which means before displacements, there's nothing wrong with the space I've given for the Q's." and i STEALTH said "actually net means after displacements. gross is before. lol" ALTON said "taken directly from the dictionary buddy: gross    /groʊs/ Show Spelled [grohs] Show IPA adjective,-er, -est, noun,pluralgross for 11, gross·es for 12, 13; verb –adjective1.without deductions; total, as the amount of sales, salary, profit, etc., be…

Ive seen people that compete use thin pvc pipes cut in half and taping it to the walls/edges of the enclosure. Does this help create better airflow? Increase SPL?

i was surfing around another sight and seen a post of a fellar wanting to check his design on a port. he was told a length by the guy , and drafted the port out accordingly. the port he presented is the exacrt length he was told. i was just thrown off by this because it is a slot port, and i thought that the end correction should of been factored in. i was told it wasn't. so does the end correction not always factor into a port design? the port folded so it was so it was not on the exterior wall, but ended inside the box along the adjacent port wall. thanks for the help. just wanting to ensure i am equiped with the right info. chop edit.... the length given was to be 26…

Who will be competing next year and in what organization and class. I will be competing in SLAP in the stock 0-160 class

Hi guys, I currently run a Fi BTL N2 12" on a Sundown saz 3000 amp. I have no problem with the electrical, even if I know I may not push all the watts this amp can deliver ! My box was designed by Bromo of Eclectic Design (or something like that) : 2.1 ft3 with a slot port (32 hz tuning) firing through the (driver) side. The sub is firing up. The box is well braced too. It sounds good, but I want more output ! I can have another box built easily, and I already own two 4" flared (on both ends) ports. Those ports are in a 3.2 ft3 box used for a Soundstream XXX 15", for now. But I can get it back fast. This box may be too big for the 12" btl. What do you think about it ? I n…

And would like help if possible from someone that is familiar with fox body mustangs hatches as they are small. Can someone please help im interested and having the box tuned to about 32 or 33hz.

hey guys, i need help making the design for a optimal sealed box for my 2 12's. http://www.soundsolutionsaudio.com/index.php/product-information/icon.html\ the problem i have is i have a rather small vehicle and the space the box has to sit in is 33" wide and 18" high but to get it in the tallest it can be is 16" if anyone could build me a diagram or point me in the right direction it would be a HUGE help. thanks in advance, zack

i have a question i have an 1.25 cubic inch pvc tube for 1 15" and i want to tune it to the peak freq. of my car. i dont know what frequency is best for spl in my car i have a 4 door mitsubishi mirage and im going to use aeroport 3" and the woofers are RE XXX thanks in advance im new to this of port is there any advantage using larger aeroports in sealed i measured in the 58 thanks

I want to do a install of 4 15s in trunk of grand prix. I will be building inside trunk. I just need help, and suggestions on designs. Let me know guys. 37" wide and with 16" tall, and roughly 50" long(from trunk opening to rear seats.

Im trying to make a box for a single 12" dcon can you guys give me your feedback and let me know what you think please? im new in building boxes this is my first and looking for it to be tuned at 32hz demensions for the box are as seen in the calculator( long story on why i chose those measurements and dont want to even explain why) let me know what you guys think please and also for my port according to this what would be the sizes of the 2 pieces of wood i would cut for it? thats only thing im confused about at this point.

What all do I need to model my zcon for the new enclosure? About to start building and want to have the enclosure design as good as I can.

Will be built in car in this area. Slot port on drivers side, sub and port firing into cab, sealed off from trunk. This is what I've come up with, but how do I figure the 90 for the length of L port? Thanks in advance.

I am working with a new AS1 competitor trying to get them a really nice score this season. Basically, rules are as follows- System must reside in trunk only, car MUST be off and play a song only. Well, he currently did a 140.2 with 2 Fi SSD 10s and an audiopipe 3000w using a 35A fuse. This is my theory- Because MECA's classes are limited on fuses + cone area.. and cone area and power go hand in hand with each other... as long as the space is there... more cone area and less power "should" result in a higher pressure output. He was able to pull just over 100A off that 35A fuse to get his score. We aren't restricted on cone area but cone area + fusing x 10 cannot surpass 55…

If have been thinking about this for too long and my brain is no longer able to figure this out on it's own Are L-pads ever used in a car audio application? I understand their use in a passive setup for home audio but what about an active setup in car audio? Hmmmmm adjusting the amplifier gain will not change sensitivity so an L-pad would be used to attenuate a higher sensitivity driver? Reason I am asking is that it can be difficult to match mid/tweeter/midbass sensitivities for an active 3-way setup. Let's say that the midbass and tweeter sensitivity is 88db 1w/1m (4 ohm). And that the midrange sensitivity is 91db 1w/m (8 ohm). I think 91db 1w/1m@8ohm is the same as …

Let me start by showing what I've done and what I'm trying to finish with... I'm planning on hot gluing wooden dowels to the fiberglass panel up to a wood speaker ring. Then wrap a big piece of cloth around the speaker ring to the back of the fiberglass panel, then stable the cloth around the ring, and glass the cloth, etc. Only problem I'm running into is, when I wrap the cloth around the ring and fiberglass, how do I staple down the cloth, since there won't be any wood to staple into on the back of the fiberglass panel. Could I glue small strips of cardboard to the back of the fiberglass and staple into that? Sorry if I'm confusing.

I am about to get a really good deal on two AA Havoc 12"s soon. And I havent got the room for a full ported box in my truck for two 12s. So heres what i'm doin. I've designed a box which is right around 2.5cuft before driver displacement. Idk how or what role the size of a sealed box plays with output or with quality. The box looks kinda like this. /l Ll It is 36" wide x 22" tall x 10" deep. With the front of the sub having a 45 Degree face starting 12" up the front size. I'll upload a pic in a few to clarify as much as my lil sketches possibly can. Also a double baffle design. Any info or help would be greatly appreciated!!
