SPL & SQ / Fabrication

I want them to pound, but I don't want them to take up all my trunk space, I want the box to be tuned around 32hz, so does anyone have any suggestions?

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…

Ok, now, i need someone to DESIGN me a sub enclosure for a FI BTL 15" Ported ~34 hz cant be more than 16.5 in tall, 34 in wide, 18 in deep..... shouldnt need to get that big now.... I love google sketchup, so if someone whipped it up on there, then i would be forever gratefull thanks for anything...

I was simply wondering what is some of the different types of Building Material are the best? I know the word best is subjective, but in this scenerio, weight is not an issue. Of course, I could simply double up on 3/4 MDF, and do some well bracing, I'm aware of that. But I'm also aware that, the material your using can greatly alter the output. Thats the main reason extreme vehicles use concrete. I am not willing to use concrete. I know I said weight is not an issue, but thats a bit much, plus would put me into the extreme class. The reason I'm asking, is because this will be my burp enclosure. I've heard of some competitors using marble, and other hard/rock like materia…

Which is better for box building liquid nail or wood glue? Any others you would suggest?? Thanks, Matt Cusack

Well I got a couple more 15" Rockford Fosgate RFR2215 Power DVC subs.. now I am ready to do my four 15's setup. At Slamology I got a 148.1 in DB Drag with 2 15's and 2 12's at 44hz. My goal with this new box build with four 15's is to hit 150db mark. I recently just started playing with Bass Box Pro and Google Sketchup and I have come up with a Design in Bass Box Pro and then tried to Model it the best I could in Google Sketchup so here it is. This will be powered by a T40001bd. 12 cubes after sub,port,bracing displacement with 1" MDF 4 6" PVC Ports 10.5" Long to get a tune at 38.01hz There will be a total of 9 1" Dowel rods for bracing in the box 4 from top to bottom 3…

Hello, I'm in need of a box design for a single hdc3.1 18 it's powered with a cab 1600.1 and the max dimensions are 35 long 37 width and 15 tall and would like it to be tuned to 32 hz but any suggestions and would be greatly appreciated!!! I found a website the I messed with and was wonder if this box would fit the specs for the 18???

hey guys, i know i have a thread already about this topic, but that was for my ranger. i now have a 2002 f150 ext. cab and my zcon is on its way so i want to start building a box. i took some measurements tonight and i have up to 6 cubes to play with here. i want ported obviously tuned to aorund 34Hz? i love my lows deep and loud haha. i will have it getting 2300 watts from my aq3500 and yes i have the electrical to back it up with no problem. now, how many cubes do you guys suggest i should go for with this kind of power, and the tuning i want? i will have the sub and port up unless told otherwise. let me know what you guys think!!

What is a good tuning point for a wall in a hatchback with 2 18's ?

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…

First-the enclosure specs for 15 inch xcons have a standard and optimal size. What are the key differences in the two? Also-I had to sell one of my amps to get through a hard time. My question is, powered by a fosgate t1500bdcp amp, should i run one sub ported at 2 ohm or both of them sealed at 1 ohm?

a great ssa member put this togather for me.... thank you sir!

In the trunk of my car, there are two bars running across the top of my trunk, that attach to my trunk lid, i suppose its there to adjust tension for my trunk lid, will if i remove those i can get an extra 2" height and that will make a large difference for my enclosure and layout in general. Anyone remove these before?

Price completly aside, how much better sound quality would you get with door pods vs components in a fully deadened door? I have a Crown Vic and my main goal is to get the best possible sound out of the components I'm gonna be getting. I'm going with the Image Dynamics XS series components. If I get them in the doors I'm gonna go with stock size 5x7s(XS-57). If I do the pods I'll go with the 6.5s(XS-65). Again my main goal is the sound quality of the comps so if the door pods sound just slightly better, than I'll pass. If the difference is dramatic though, its something I'm really gonna take a look at. I know there are a lot of variables involved in anything like this s…

Hey, I am looking to build an enclosure for one Sundown E-12 in the near future. I plan on putting it into a 2.5 cubic foot enclosure. (PWK recommends an enclosure for the E-12 of at least 60L (~2.1 cu ft) for a more linear response) I also want to use a 4" aeroport (precision port) 10.25 inches long for a tuning of 32 Hz. I think my question is, would it be alright to tune this box to 30 Hz? All it would require is 12 of port length compared to the ten and a quarter. I'm just slightly confused because I have heard not to tune too far below a subs res. freq. because it might cause roll-off right at the tuning. If it sounds stupid, that's because I read it once somewhere o…

I've decided to try a ported enclosure for my sa-10 just for kicks. I'm thinking 1.0ft^3 tuned to around 33hz. I'm not set on 33hz, it's somewhat of a guess as to what may sound good - I'm going for sq more than spl and listen to all genres so I need it to give me the accurate punch of rock as well as the lows in rap. My box is limited to a size of 8"d x 13h x 33"w The sub will pretty much be right up against the rear shelf of the car behind the passenger seats in a porsche 911 so I was thinking it would be better to go with a side firing aeroport over a rectangular port. My box would measure roughly 8"d x 12.5"h x 31"w, making it 1.12ft^3 after sub displacement, this wou…

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…

Hello all, I'm new to this forum, but not to car audio. I am however new to the Sundown woofers. I'm hoping you all can lend some help and thank you in advance on my enclosure design. What I have is an 05 Acura TL I'm doin a pair of Sundown SA12s in the trunk. Subs to be fired foward and a 6in Aero either out the back or side. I have tried several enclosures with foward fired subs & port, but the car just did not really like it. Last setup was a single CV Stroker12, power was supplied by an O.S. USamps VLX400 1ohm mono. I had good results with two 4in PVC ports fired back, Sub obviously foward. Then tried a 6in Aero out the drivers side of box. The Aero was slightly b…

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

Anyone know of of a snug fitting dual sub box that'll fit in back of the second seats? Im taking out far back seats want to leave middle seats. Only wanting to do dual 15" subs. Should they be enclosed also?

Have a mock up design 6.73cubues net after port and everything wondering if i really need 29inchsa of port per cube or is that oclver kill trying squeeze 7cubes net orafter more ifthe possible. Also running a crescendo 3500bc at 1ohma on strong electrical so ill have the zcon moving displacing a good amount of air. Just a simple port area question dont want waste space .

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

Thanks in advance for the help. Alright I am planning on getting a 12" Fi Q D2 and already ordered a sundown SAZ-1000D to power it. I've never built a box before and I dont trust the audio shop here. I want to build a L shaped ported box. Its going in a 1997 chevy blazer so I have room. First should I go sub up port back or sub back port back? What are the benefits of each keep in mind I'm not going for spl. According to Fi "Ported box we recommend using 1.8-2.5 cubic feet @ 28-33Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume." So I…

Not sure how to explain what Im experiencing...but it seems that when running sine wave freq sweeps my system drops out about the 57-63Hz. Very annoying, and cannot seem to find a way to fix. I have 6.5 coponents in the doors (stock locations) and a 15" Xcon ported (tuned to 32Hz), doors have been sound deadened (dynamat,mlv etc) I have tried using different crossover settings (50,63,80,100HZ etc) to separate the sub and components, I have tried letting the sub only play these freqs, tried the components only, tried to EQ (my HU only allows 40,80...) Im just baffled...could this possibly be a Null from my listening position? Maybe the components being too far off axis? E…
