Can I mount the subwoofer in the port, like this? And... Would a 12"Height 1"Wide 6"Deep port be the same as a 6"Height 2"Wide 6"Deep port? Would it sound any different?

What would be considered too small for a round port (in terms of diameter)? I'm trying to design a ported box (0.7 ft^3 ~ 24hz) w/ round ports for an RL-I 8" and the only diameter port I can use w/ a reasonable length is less than 1.5"...won't this create noise? I just can't imagine using a 1" port for that monster... What's the rule of thumb y'all?

Pic of specs (or really close to, but hows the design, first ever, opinons, ideas, positive feeback.... will it work?? lol thanks guys!!

This will be my first wall build, I've been doing a lot of reading and looking at build logs. I should start by saying the plan is 2-3 (if I can fit 3) RE XXX 15's, on either a DC Audio 12k or Stetsom 14K. I think I'm going to go with Baltic Birch for weight and strength, I am seeing guys using 2 by 4 bracing, also seeing them use it for the back of the wall outside, what is the purpose? is it needed? what other ways would you strengthen the wall or face? the subs weigh 76lbs a piece. I was thinking 3-4 layer front face, double layer everywhere else, fully resin the box. How much bracing would you recommend? If you have pics or anything else you might recommend I'm open …

If someone was going to build a sealed enclosure, and the woofer in question listed a box size of, say 0.75^3 to 1.5^3, how do you determine what size ^3 would best suit the woofer? Is that something that the tsparameter would tell you? Or, just build something in that size range and get equal results??? Just curious...

I'm trying to figure out an enclosure configuration for 3 SA-10s, just not sure which way to go. Was looking at doing a downfire enclosure with an aeroport(s) firing to the side,. Just curious if there is any drawbacks to something like this. I like the idea of it being less visible, as well being a little more protected from the elements if the top is down. If it's a terrible idea, I'm all ears for better options. Thanks

Anyone have the meca world finals results? Just curious on how our shop vehicles would compare..

Hey guys. Its time to try something new. Not sure what will happen to the sound if i tune my box higher or make it larger. I'm 1.5^3 tuned to 28hz now. love the flat response curve and helps the sub sound really low. What would happen to sq if I make the enclosure larger like 2.0^3 and/or tune higher? TIA

i have a 1991 mustang convertible with a shoe box for a trunk. the dimensions are 10h x 9-11D x 40 width. i've been hearing great things about how the sa 8 is a great spl small woofer and wanted to know if i could really fit more than one into a box with such small max dimensions. i also need amp suggestions to run the one or two i will be getting thanks!

I am planning on designing a box for my rli-8s I am getting and I am trying to figure out a way to latch down the box in 2 places. I want the box to sit in the well for daily driving and I want it to sit up top when I take the t-tops off. I want to design something like the back seats on the nissan quests. There is a compartment where it hinges down into to stow the seats. I am thinking about going to the junkyard and looking around for some hinges and latches that I could use. Does anyone have any ideas? I can draw it up in paint if yall want. Thanks guys

Ok so I am going to be going to sevierville tomorrow and stopping by the place my brother in law works. He said I was more than welcome to use the equipment they have. --read cabinet shop-- Sooo I figure why not go ahead and make a better box for the one avalanche. I'm looking for 3.5-4 cubes, tuned to 21hz. I would like it to be 30"W X 16-18" H X whatever deep. 16" high is better than 18 cause it'd be easier to fit, but i could do 18 if it really helps that much. I guess i will do slot ports so i can actually get a working box quickly. I will probably be using 3/4" MDF. I'm thinking a port on each side with the woofer in the middle. BTW its a 15" sub and the …

Hi all, I'm designing a custom boot for my car, what is the best way to place 2 x 12" phase aliante subs in a boot? I was told the best place would be one on each side (one on left side and the other one on the other side). and I would love to do a fibreglass job something like this: but on my car would be 2 of them..so one on the left and the other on the the other side. what do you think? or is it better to do something like this (which one is better, sub firing the front of the car or the rear)?:

Does anyone have the specs for the Fi BTL 15" subs. I am installing 2 of them for a customer, but he doesn't have any perameters for the subs. He is putting a Hifonics Brutus 2600 watt RMS d class amp on each sub. It is going to be in an old school s-10 2-door Blazer walled off right behind the front seats. Built for competition only, wanting to hit the biggest legal spl number at USAC competition. Any help would be appreciated. Thanks

Well, because i will be removing the weight issue in my car soon, nothing stands in my way now for my next build so i need anyone's opinions on the strongest build u can think of. Any negative thoughts about any methods is 100% welcome as i don't want something that will fail. Here is one method i have been thinking about but remember, i'm looking for the best option(within costs, hehe, dont wanna spend several grand on an enclosure) Option1- Lay 2x4s on their side(so 3.5" thick) all the way around the car. Then inside of this chamber, lay 1 layer of 3\4" Oak inside. Install Angle Iron outside of the enclosure and weld 1\8" thick steel bars to all corners of the Angle Ir…

Hey guys, trying to get an enclosure made for me, but im not sure where to start. the jl stealthbox (http://mobile.jlaudio.com/products_stealthbox_detail.php?fit_id=1620) is exactly what i want, except i dont want the w3, but they wont sell just the enclosure. Does anyone know someone who could make something similar for me?

Here is an idea i am throwing around for my 99 neon... 5.25 component set up front for the hi/hi-mids have 6x9 holes in the rear deck, but will enlarge them slightly to encompass 8"(7.25 cutout) midbass drivers 50-200 hz response.. then have 2 12's in aported box in the trunk Is this a sound design to put the midbass on the rear deck?? I have read numerous things about running mono for the rears/keep away from highs back there cuz it moves the center image backwards types of things... Also is this going to be terrible placement for the "free air" midbass speakers on the rear deck having their back wave interfering with the sub output... (really the rear deck is the only p…
