SPL & SQ / Fabrication

I was wondering how I can properly set and adjustable a LOC with a stock radio and aftermarket amps. Equipment: Stock H/U SVEN LOC Zed Minilith Sundown 100.4 The RCA's after the H/U are going into the Mini and split (y adaptors) to the sundown. The LOC has four individual knobs for setting the input signal. Sorry if this is not enough.

I'm building a box that's, according to my calculations: 1.9959 cubic ft (not including port and .12ft^3 sub displacement), with a port area of 28.75 square in, and port length of 33 in. This box should get me about 32-33 Hz. This box is for a single 12" SI Mag that's going to be powered by a Sundown SAE-1000D. Anyway, this is only my second box build, and my box building skills ain't nowhere close to most on this forum. But I'm wondering how some of my problems will effect the actual sound of the sub. My problems lie in the port, which runs through one side of the box, and continues around the back of the box. So, these are my problems with the port: 1. The port a…

What numbers are you hitting with windows up, vs down? I need some numbers for this thing I'm doing. Thanks!

Freeking Sweeeeeeeeeeeet Show... enuff of me yacking now for the pics I blew the cone off the sub in the first run and still pulled off a 149.2db with 1 SoundStream T4 15 / 1 blown - 2x SAZ 1500ds strapped sub killer was @ 1.1ohm wired other sub to 0.7ohm added the NSB battery ran out of Sundown brochures really fast : Jacob please send more !!! was way short on info for the mobb...eagger to get a SD amp... took my class... 2x 1place trophys

Let me start off with the basics. I have an '01 Accord and I'm looking to do at least 140 on music, but the louder the better, but I want it to sound pretty good still. So, in the works is possibly a 5200, whether it will be a 15 or 18, I don't know, thats why I'm comin to you guys. I have a 170A alt, Odyssey 1200 under the hood and 2150 in the trunk. I have an RF T30001 for my amp. I'll be able to do either a 15 or 18 ported (the 18 requires 5 cubes after all displacement). THis works great for me since I fit in an enclosure that was 5.5 cubes after displacement. Whether a 15 or 18, it will fire up due to height restrictions. I'm just wanting to know what will be the di…

i would like some idea's please i have about 3.352 cft internal external 40.5"width 10.5"height 18 depth,i wish to use 2 or 3 old usd 1260 subs. speaker paremeter RE 5.24 QTS 0.39 QMS 15.60 FS 12.29 QES 0.40 XMAS 3.708 LE 1.01 Z 8 OMH PE 200 i would like to try and build a transmissione line box. i found this info for building the above box.please can any one help me all help will be gratefuly recieved. below is an example of how to make a transmission line 43.46 / 4 = 10.86 10.86 is the throat length of the enclosure.

seeing that SQ is subjective to the person lisening, I have redefined SQ: 1. Having Quality speakers, able to be clear enuff to sound good over subs doing 152db Daily 2. having an amp ablt to push that set of mids & highs without distorting. 3. Hu has to have SQ Freq control features feel free to add to the list

Ok, I got my first 15" sub today. All I've ever dealt with before are 10's and 12's. At the moment I have a pair of 12's in the back of my 97 Grand am, each one seeing 1.25 cubes sealed. The box is easy to work with, I can have the whole thing pulled out in a matter of minutes. I would like to have something similar with this 15. One problem....the clearance through the backseat is only 13.5 inches, I believe. The space to go in through the back isn't very easy to work with either. If I build a box that has the sub laying on it's back with the cone up, I really think I'll lose a lot of the potential from the sub that I would normally get from rear-firing it. Also, I …

What kind of Box you sugest for 2x Pioneer 307D2 just for SPL Street B class. Dimensions, Port, and other things. Thank`s

I found a formula that seems to work at http://www.caraudio911.com/ under designing a ported box. But I was wondering why on step four they say to subtract half the port width from the port lenght to get your physical port lenght? When I made my box I dont think that I did this so I may be building a new one if this is important. I was also wondering if this formula works or has been used by anyone here?

The guys at kicker said to tune to 39hz for 4x12" CVR's in a 9sq foot box. I don't see many people tuning much higher than 35hz though. So should I take their word for it and tune for 39hz or drop down to 35? This is my first ported box so, I'm somewhat at a loss.

If I had (4) 6 1/2's and I went to (3) 8's, how much louder would I be?

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?

I am a novice and I have heard it discussed about "tuning" to 30-35 htz. How is this accomplished?

i am sick of not having an SQ/SPL Hybrid class we could call it LSQ-VFL im bored with just 1 or the other anyone else like to hear the rest of the music loud enuff to mush your brain into peanut butter.... without distortion ? or as lil as possiable

This is my first post on here, and need some advice from the BTL gurus I just picked up two BTL 18's, dual 2's, fully loaded, and will be running them off of two modded Memphis Mojo MC-2000d amplifiers (1 on each driver at 1 ohm), approx. 3000 watts each. In my vehicle, which is a 2007 Toyota FJ Cruiser, I don't have a whole lot of useable space to work with and still maintain practicality, so the enclosure is going to be a bit tight for specs. I will run the subs inverted to try to save as much airspace as I can, but I only have a total of 11.2 cubes to work with, before port displacement. This is going to be a daily setup, and I am more than likely going to build it…

http://www.woofersetc.com/index.cfm?fuseac...Product_ID=5091 I saw this on ROE and couldn't beleive the price! Are these like last years version of the 61i that is currently on the CDT "gold" web site. I remember old CDT eurosport, and only heard them once, I was pretty impressed but it was a 3 way. I just don't have that kind of cash ATM, and won't for a while with all the rest on my build up. Bump if anyone has experience with these? I might jump on this and let the H/U issue wait.. if these are a value anyone want to borrow me another 300 bucks so I can get 2 sets I would hate to miss out on sucha pwn sauce deal if these are in fact good?? lol I'm looking for some…

Simple. All anyone would have to do to receive competitor pricing is say "i do local comps". Hell if this were a way to get dealer pricing or even near it EVERYONE would say so. This kind of marketing is not in the companies best interest in any way shape or form. MSRP is where the money is at,.....period. What makes a person a decent candidate? One who actually listens to the questions he has asked. Done his homework, built 3026 different enclosures, pissed off his wife, neglected his kids, spent his college money, given up all hope of daily music, uses a product that can actually "get loud", is prepared to spend 1/4 of what he makes on traveling/admission/equip…

Alrighty soo I've been wanting to do my own custom install for a while now. I wanted to acheive a more compact design- one that didnt take up much trunk space, was easy to remove if needed and that was still loud enough and cool looking to not only make me happy, but impress my friends too. Thus came the idea of the sono tube! With the design concept settled, I started looking for the perfect sub to make all the magic happen. I wanted something beefy, but in a 10". After some research, I ended up going with tcsounds oem tc10 and their matchin passive radiator (which might I add is one sexy little thing!!). http://www.mp3car.com/vbulletin/attachment...uild-d-cone.jpg http…

Right now I have a 2.2cubes @ 32hz with 34.50sq.in. of port area with 1100rms for my daily driver. I want to build a pure spl box and a pure sq box before the winter comes. I have 34inches in width and 13inches in hieght. I need to know the tunning, port area, and cubes for each enclosure. I heard spl enclosures should be small and have alot of port area. I'm not sure what kind of boxes I should build so i'd figure i'd ask here since noone knows the icon better than you guys, Thankz.

Hello, I was wondering whether it was possible to use two different port length on a same box: For example I need 31.5 inch of port length total for 2 x 3" round ports. Can I make one 14" and the other 17.5"??? It's just that it is quite difficult for me to fit those two ports inside the box, outside would be possible but aestethically wouldn't be good. Thanks guyz, Kelvin
