2x15" Home enclosure
 

Hey, Im gonna be snagging 2 15" clarion Swr 3841's Of a friend of mine for cheap. But thats the easy part :P Ive been trying to figure Out how to design a box for these puppies but cant find the specs and am having a hard time gripping the Idea of how to tune vents. It sorta gets me a lil TICKED but If anybody can find specs For them that would be nice. Im gonna be using these in home and a while back found that You can use computer power supplies to supply juice to car amps, yet I think I migght get ELectricuted because it seems a lil confusing. Considering half the videos are of little kids showing me how to wire these things. I know they are 600watt max and have single 4ohm voice coil, so depending on whether I Wire them to a home reciever 8ohms with crossovers or to a car amp on Comp P.S will determine if I run them, series or parrallel. My main question. more of a favour I think, if anybody has some extra time could you make a simple yet effective enclosure with dimension *vented* that would hit down to 20-28 hz???? If that is not to low. Remember its in my house so lots of Ft^3 is fine No limitations to size. I know home theatre is usually LOW. but the design Would be VERY MUCH appreciated as I dont know Sh*t all about tuning vents:dunno:. Ive looked all over but everywhere I go Someone throws something in that messes me right up and sends me back to stage one:sly:. Ive read alot and think I know the basics of it but any tips and or pointers would be awesome.NOT ONLY ABOUT VENT\ENCLOSURE DESIGN BUT ABOUT ANYTHING YOU THINK IS NOTABLE FOR A BEGINNER Thanks alot guys.:smilie_da

it isver simpel to hook up comp p.s to a car audio amp i have car audio in my room and thats how i run my amps

i would suggest only using one woofer unless you want a giant enclosure sitting in your room.
here is something i whipped up thats just a generic ported enclosure
3 cubic feet @ 26hz

Really? Do you have a link by any chance, showing directions? Ill give youtube another try.


And jalat how much bigger do you think it should\would be to get that second one in there. Cuz I have it here no matter what, Are you saying I should Build 2 of those boxes?

If I can figure out the amp with psu problem i can build 2 if not Im going to have to run them in a series meaning in same box, Ill pm you or something when I find out. Ill try to keep updates comin if possible, Right now All I have for amping is a Harmon kardon reciever + shelf amp. Dont know exact wattage but its a bit older and it was pumpin a 1000 watt 12" at one time. Also have a 500 watt P.S I gotta read up on how the amps and energy converts. Sh*t theres a bit to learn xD better get reading :stroke: :cheeky4:





Also wondering how you get measurements to show up in sketchup, I D\L it and its workin good, itsjust a lil confusin aha

Your looking at the minimum of 5.5 cubic feet for two 15's and then having to tune it so low... its gonna be a large, large enclosure.

ya i can wip you up a digram

here is the info you need if you have any qustions just ask i will be more then happy to help you out

Hey thanx that should help with a few faults in my knowledge, But I hope I have enough power in the end! gotta find a cheap car amp now :appl:

"Your looking at the minimum of 5.5 cubic feet for two 15's and then having to tune it so low... its gonna be a large, large enclosure."



Size doesnt matter to much I have much room =D But I was also wondering about crossovers, I was readin about cutoffs and how it can help the power to output effficiency, Im guesssing if I get a fairly good amp I should be aight with the built in ?

no problem and my i suggest go to a pawn shot to get your amp

Aight we got a few of those around here, cept they dont get much business so I think they over charge, might try craigslist, The subs are 300 watt rms So Im guessing a roughly 800W@4 ohm, 2 channel amp should do, Or wtvr I can find, just dont wanna over power them and would rather pay for a good quallity low power then a shitty quality high power. :smilie_da

Ill try to go on a scavenge this weekend to see if I can find anything worthy of my room.

ahaha But im on a budget so I will be limited :( :( :P

i bought all my stuff from a pawn shop and nothing has gon rong with it '

i might be wrong but even the best pc power supply will only supply u with enough current to power a very very small amp and those psus are gonna cost u over 100.00 bux. just buy a plate amp from partsexpress and be done with it. itll probably cost u a little more but it wont be halfassed :smokin:

car audio in my room!
here is my system in my room my amp for my subs is running off a sealed lead acid battery witch i charge every couple of weeks and have never had an issue with it and my amp for my spekers run of a psu

I have done a few sub boxes for HT....usually for friends who bought a HTB with a powered sub output. The subs that come with such systems are pretty small....using them in a medium to large room causes a serious drop in the bottom end, which sucks for movies etc.

Since you have lots of space, get the most out of those subs.

I couldn't find the specs for that model number on the Clarion site, if you don't want to experiment with vented boxes, throw the pair in 5 or 6cuft and seal 'em up tight. It will help if you point one driver into the room and one at the floor, elevating the box about 3-4" off the floor with feet. Put separate terminals for each sub on the box.

If you are using an HTB receiver, it will have some kind of subwoofer output, either speaker or RCA level. This output is already crossed over at a point where it will blend with the HP outputs to the other 5 speakers. If you need to, use a LOC to drop the signal down to RCA level and use any old stereo amp to drive your subs....wire them in stereo, use one sub for each channel and set your levels with the volume control on the stereo amp. Running a home amp at 4ohms will put extra stress on it, make sure it has lots of airflow around it and check it for overheating the first few times you use it.

I have built several different units like this over the last few years....some I gave to friends, a pair are still in the garage and I still have a few woofers left over....:D

HTH

.......... :O =P lmao I dunno about it but I just got so lost in those acronyms lmao I will jsut look them up on google. BUt anyways, isnt 6 Ft^3 a lil big for a sealed enclosure or is that needed to hit the lows? Also whata bout runing the subs inseries to get an 8ohm load making it easier on the amp? or what about bridging?? I duno what bridging does with ohm handling =d

Thats sounds pretty dope I was thinking of gettin a converter plug infor 12volt DC and just plug that t the amp and run a ground to outside :dunno:

And I beieve you about the second hand stuff workin good, just gotta know what to look for.:cAnada::cAnada:

Just get a 500 Bash amp from Creative Sound Solutions - Loudspeakers, Parts and DIY Speaker Kits that will save you duty and shipping.

My home amp has sub out....does yours?I went to the pawn shop and bought an SAE 250 w amp and just ran a sub cable from my HK to the SAE,and it rips(with my 2 old school DR.C's

You will strugle to find a largwe enough power supply to do the car amp thing well.

ya it hits pretty hard i like it and your right you have to no what you are looking t when you buy from stors like that

how do you know its tuned to 26hz if you dont have the woofer parameters

i'm jesus...

i just designed it on RE Audio's L-Port enclosure calculator. I took into account that its not an accurate program, and i know its flaws. its the best i can do without any specs

so you guessed

yes i did. can you do any better with no parameters?

normally, the generule rule for a 15" woofer is 2-2.5 cubes sealed and 3-5 cubic feet ported

absolutely not....but again i wouldnt suggest a box design without them

lol Well It will have to do for now, If you know any other 15" single coils around 600 watts, take a look at the stats. I cant find any, But thats cuz im stupid :P

Here is the manual:


http://www.clarion.com/us/en/MungoBl...41(Manual).pdf


Recommended box volume is 4 ft^3 per sub tuned at 32 hz....sealed may be the way to go.

OK.....

HTB = Home Theater in a Box

RCA you know

LOC = Line Output Converter - drops speaker level outputs down to RCA level voltages.

The large enclosure size will extend the frequency response of the enclosure lower. This come at a price....the power handling of the driver goes down, but since you will only be using 100-150w per side they should be fine. It also results in a "fatter" bottom end which can be handy during movie sound effects. If they sound too "loose" to your ear during music or whatever, you can throw things in the box to take up some airspace and "tighten" up the sound. That's one of the advantages of using a sealed box in this situation.

I would think all the extra hardware required to use car audio amps and processors would pretty much equal what it will cost for the right home equipment....and then there's the extra hassle of putting it all together.....:dunno:

If you run the drivers in series for that 8ohm load, you should get a mono subwoofer plate amp as suggested above. Not only will you get more power than a typical home stereo amp or receiver, it will have gain and xover controls on it to help with the setup. Having looked at the specs for that particular amp, it does 500w at a 4ohm....sooo......you could build a box for 1 of the subs (around 2.5cuft or so) and just shove it in a corner.....:smilie_da

Even a single 15" sub with 500w in a small to medium room will generate a lot of bass.....hopefully the rest of the system will keep up......:D

HTH

THanks alot!! =] Everybody is beein real helpful, thanks again :smilie_da

Yes I agree that It would probably cost more. But I really have no clue as to where to order my parts in from, I know the U.S has Parts express but Do they ship over boreder, THen Also do they do COD? Cuz Im only 16 and dont quite have a Visa or want one :O =p



Edit: Just noticed the FS is 34hz I read that the FS has a tight coRrelation to the lowest frequency that its able to produce??? Also WTF IS F3?

What I was also thinking At a l8er time if things work out is to build a ported box for a pair of Titanic MK3's =D I love the look of those and the Xmax would make for some heartthrobbing HT experience. NOT YET L8ERL8ER xD....... Also What did you say about using an HTB reciever? I heard a while back they use all kinds up ****ed up Impedances made for certain speakers so that you can switch it out. Is this right? Cause the cost of a good one is quite a bit. Id probs go for 8.1 then run sub output to a wall amp???? good idea??? lol I dunno we shall see, I have some upcoming sales of bike parts so Might make muny more available.

So if anybody wants to know, I just got the subs today. I hope to be acquiring MDF a.s.a.p and getting on the box. THe subs dont have squeeze clip in for the wires and Im wondering, Since I dont have a solder gun, How I would get wires connected?? Im a lil lost atm. The + & - look like those little metal slide on things. Any Help? =P SHould have pics of them up soon. Thanks

-Mike

Got any pics??

Yup just took some Gota figure out how to uplaod now, SHould be in next post :smilie_da

THey arent the best But They do tower over that 100W 10" ;) Which Btw hits dam hard when placed under my desk, cant wait for 2 15's Im gonna have more bass then most the local Noob tuners =D Most people round here just buy future shope premades lol

Kicker CVR15's
 

I recently built 2 Boxes for Home Subs.
They are each 3 cu ft @ 32 Hz. They told me to tune lower for home theater, but I use them for Music much louder than Movies. I'm Really glad I didn't tune lower.
I use a home stereo amp to power them 450W @ 2ohms, Each.

Aha thats F*uckin awesome! =D But I was wonedering, are those magnetically shielded ? :P I also got a question, how do you mount the subs to the box, cuz I was thinkin screws but those would either rip up the mdf of just work their way out.. And what about sealing the sub gasket area?

Only need a shielded speaker with an old TV, new ones it does not matter.

If you really wanna see a nice HT sub look at a TC/Audiopulse LMS 5400.

As for mounting the subs Machine screws and Hurricane nuts, not T- nuts, is the best option, otherwise there is specific screws you can use for MDF.


Ive been looking at a SVS ultra PB-13 lately got a HT sub, but may go DIY.

Aight sounds dope, What about Titanic Mk3's ? They have a nice 20mm of excursion to mess arond with =D Only run about 200 some odd dollars
