SPL & SQ / Fabrication

I had a last minute change of heart and decided to scoop a pair of Obsidian 18's. Can anyone give me a general idea of what size to build it? I am still going to get a BC2000 or a SAZ-1500 (The sundown is so much prettier .-. ) and I would like to tune it lowish for chopped and screwed music. Is 26hz too low to be realistic for music? I don't listen to hardly any rock or metal, mostly slowed rap so tightness and accuracy are hardly concerns of mine (my xplodes are going into the fire pit though) What would be an optimal size for a pair of 18's? Once I get a feel for how big it needs to be, i'm going to see what dimensions I can squeeze out to keep the box as low as po…

I am getting 2 Fi SSD 15's and I am wanting to get some pretty deep bass out of them. So what kind of box should I get to get the most out of them? If ported, slot or round? tuned to how many hz? Thanks in advance ~MadroX

willl be running a rockford fosgate t1500 on a 15" xcon listening to all sorts of music sq over spl but i still wanna move a lil bit of hair if it makes a difference does it make a big difference if the sub is up port back vs both up or both back? its going in a 98 Honda CRV....simular to the picture bellow, id post mine but im having a hard time figuring it out.

This H2 Hummer was at the 2003 North of the Border Bash.. it got 143db in the SPL competition.. The guy doesn't compete.. he just wanted to see where he stands in the SPL realm...

so i need the calculations needed to figure out my problem(or the answers) with this build want it to be a true not done on a online cal.(unless one will give true port cal within a 2hz of needed frequency) box 20h*48*40*d using 6in PVC? thanks to all that have any input for me. its 4 15s and want to tune between 30 to 34hz.

So I come today bearing questions... I have two ideas for a system and really am at a standstill and could use some advice. Both ideas will be forward firing with the truck sealed off from the front. My first idea is two 12's in a sealed box. Due to the fact that the max height in the trunk is 12.5in, I would have to tilt the sub back to make it fit, and for the sake of visuals, tilting them inward at the same time. I would prefer this setup, but due to limited resources, I'm not sure if I could cut any mdf with the angled edges required to achieve this. So this leads to my second idea... If I ran two 10in subs, I could run them straight up and down, and I could port them…

i was reading the new england spl site and i see it other places what dose CRX mean and why cant you have it

I have really thinking about trying to run surround sound into my car but don't want to spend very much I want to keep my active 3way system I should be wiring this week, cross-overed in my deck I like my alpine 7998. What options do I have no cheap junk like pyle please

So I couldn't sleep last night and decided to start designing the box I want to build for my 4 SA-10s that im getting in next week. Thought I'd post up the pics.... Also, After discussing yesterday with a few of you and trying to decide how to do port area and everything with some aero ports, I decided on the (4) 4" aero ports.. But then after I designed it and everything I realized that the tuning you guys said was about 39hz.... and Sundown recommends 30-35hz for these subs.. 39hz was like the only tuning we could get to work in order to get enough port area for my setup.. So I wanted to make sure before I buy everything and build this,.. Are the subs going to do/sound …

Hey guys I have a question I bought 4 3 inch aeros to be tuned to 31 hz they are going to be 12.3 inches each will this sound good I'm using a saz 3000d witha cascade designs omega 18 itshould pound right thank to all who help

What is box impediance rise and how is it calculated.

Want to build a series-tunes 6th order for a Single Fi Car Audio SSD 18. Not sure where to start I know 6th orders are more complex to design and more of a trial and error build but if I never try it out I will never learn. So of course the goal is to successfully build a 6th order but depending on the final results if it does not meet expectations there will be adjustments. Also if non of the revisions succeed I will fall back on a standard Ported Enclosure . Please if you have any useful information on 6th order designing/building It would be awesome if you can share them with me . Thanks in advancez max dimension - height 30” - depth 21” - width 38…

Well chaps I'm not 100% happpy with the SPL of my box, its 16.5cuft before displacement, and tuned onto 30hz, port area is 8.3in^2 per cuft, now recommended space for the subs is 6.5 per driver, and I presume port area should be 10^2inches per cuft, so should I line the entire inside of the box with an extra skin of MDF(flex is another issue except on the front baffle) this will reduce area, and also should I change the port for a larger one on the same tuning?? Any advice greatly appreciated lads

does anyone know if a single sundown audio sa-10 would sound good in a box tune at 45hz ?

Gettin ready to start on a new build. Will consist of: 15" Sundown Nightshade D2 Alphasonik 1000HCA (Possibly saz1500) All 1/0 Exide Orbital Deep Cycle Damplifier Pro will be installed on all doors and on hatch and on the floor from the back seats back. I have more for rest of truck but probably wont have time to get it all on at first. I want to be able to put up some good numbers on the TL so what kind of design you got for me? Should I do a slot port or aero? About what size box and tuned to what? Thanks 3 cu ft tuned to 36hz with 3 4" flares?

Vehicle: toyota camry 1999 Location: trunk firing forward Space: 39w 14t 25d available Subs: 2 ssa gcon 10s Slot port Music : rap , rock Goal: everyday box Tuning : 33 hz ? Volume 2.5 to 3.0 cu. ft.? Amp: sundown 1200d I'm pretty good at making things out of wood just need a box design and cut sheet You can email me at [email protected]

Ok, well I just got a newer vehicle (2001 chevy tahoe). After spending my limit to upgrade my substage, I had my alpine 9831 from about 2-3 years ago die on me. I am thinking I'll get a cda-9887 to replace is since it will be pretty much a drop in change, and I can save some of my older cables. I'm really not that happy with the eq it has, so I'm considering adding one in there. I've never done this before, and while I've been researching it everyone has a different opinion as to what I should look for, so any suggestions will be appreciated. I have been considering adding 2 sets of 6.5 components up front, so I can keep my factory look without a large pod sticking out f…

I am going, and I know team gates a a bunch of other big guns will be there, anyone else from here? I am rolling with Ray and the Caton Customs crew, but I am not going to show, I dont have time between then and now to prep my car, nor are my pods built yet

Who has any experience with CF? such as: http://www.fibreglast.com/category.php?cat...src=HelpfulProd

http://www.springshowdown.com/main07.html How many of you fools will be at the show? There are no shows in this area, so i'm glad that MECA is finally in this area. With that being said, all of the haters out there(you know who you are), don't start any negative comments

ok so between my 2 15's im going to have about 400 square inches of port area, and i need to know if figuring out tuning frequency is the same as like a round or slot port. or if 400 is too much lemme know. i have figured 355 per sub so 2/3rds of that is about 220 per sub. but the box is going to be aboue 3.5-3.8 cubes per sub and i would like it to be tuned to around 35 hz. but i have no idea how long i need to make the port or anything like that. so any tips or tricks are well appreciated.

i've been at this for awhile trying to get a design for 2 15'' lvl 3's.. i wanna go subs up port back in my tahoe. any help would be appreciated.

any body have it its impossible to find
