How do I make my speakers?
Ok, I'm kinda new at this but I'm planning to build my own set of speaker cabinets. I'm planning at putting two 12" subwoofers, two 12" inch woofers, two 6" mid bass drivers, and three 3 3/4" titanium tweeters in each cabinet. Ambitous, yes, but I'm only 14 so why not.
Anyway, these are the parts I'm looking at using to build my cabinets.
Hifonics Brutus subwoofers rated 600 watts rms / 1200 watts peak and they come in 2 ohm and 4 ohm versions.
Pyle PYM1298 woofers rated 600 watts rms / 1200 watts peak at 8 ohm.
Pyle PDMW6 mid bass drivers rated 125 watts rms / 250 watts peak at 8 ohm.
And Pyle PDBT18 titanium tweeters rated 200 watts rms / 400 watts peak at 4 to 8 ohm.
Now these ratings are per speaker and they are only what the companies that make them claim. Totaled each cab would have a rating of 2900 watts rms / 6100 watts peak.
As for powering these beasts I was thinking about installing two DJ power amplifiers on each cabinet. I'm looking at some Gli Pro amplifiers that claim a 4000 watt rating each which I seriously doubt at a price of $250 each. But assuming they are no good I was also eyeballing a set of Pyle DJ amps that seem more realistic with an output rating of 3000 watts each at $350 apiece.
Now I know there are audio addicts out there that know all of this stuff like the back of their hand and know about these brands and their reputation so that's why I put up the companies name and model #. I'd like to know about what these parts are actually about if they really are a steal or if I'm gonna be pissed when they turn out to be an expensive pile of junk.
And if you know of anything better or have any suggestions as to what I should buy please let me know.For example would I'd be better off getting the 2 ohm or 4 ohm version of the sub. I figure the 4 ohm sub is what I should get.
Also, I'm also wondering if I could just use a DJ crossover for my cabs and if so would I need one or two and if a Behringer CX2310 3 way mono crossover would work for me.
Also would I need anything else to set up my cabs besides the terminals, wiring, and ports?
Any input will help me out but keep in mind I'm not looking at spending anything more than $2500 on this. If I didn't give enough info sorry, like I said I'm new at this.
I want these speakers to blow anything my friends got out of the water and the reason I'm using car audio brands is because it's much cheaper and I'm lookin for power more than sound qaulity.
Re: How do I make my speakers?
You could do much better for less money, and smaller size.
You are on the right track with Behringer electronics... their stuff is cheap but functional. The DCX2496 is more money, but it gives you a complete speaker processor with crossovers, limiters and EQ. A couple of EP-2500 power amps would give you about 2400 watts total, and leave you with change from a $1000 bill.
For drivers, assuming you're looking to build up a modest PA rig, Eminence drivers are good value. Maybe an 18" sub per side in a ported box, or something smaller (12" or 15") in a folded horn. Check out speakerplans.com, or Bill Fitzmaurice's plans http://www.billfitzmaurice.com/ or the horn cabinet for the Adire Tempest http://www.creativesound.ca/details....pest%20Classic
If this is just for home use, this sub would be great in a normal sealed or vented cabinet instead; check out the plans the Adire provides.
For the top end, probably a two-way would do the job. Like the Adire HE10.1: plans here: http://www.adireaudio.com/Files/HE10-1Plans.PDF
$600 would get you a pair of Tempests and a pair of HE10.1 kits. You may have to exercise some caution to avoid blowing the HE10.1's, but with the Tempests handling the bass they may live. Wiring an automotive light bulb in series with the tweeters wouldn't be a bad idea though.
One big, final tip: use a kit or plans... there's an awful lot of arcane knowledge that goes into designing a speaker, so if you can find a set of plans that's close to what you want, save yourself a lot of frastration and use them.
Okay, you're 14, and, no offense, your design shows it. You're falling for the "bigger is better" approach. You want volume, so you think throwing drivers and wattage is going to do it.
Here's a little advice. Start off by reading some of the speaker building thread, you'll learn alot. Second, start smaller, focus on either the sub section or the full range section.
I'm assuming this will be in a house, either the basement or your bedroom. Neither location needs that kind of wattage to make a lot of sound fill the relatively small spaces. The kind of wattage you're talking about is used in clubs and LARGE spaces.
What do you currently listen through? Do you have a system currently that you're looking to upgrade? If so, let us know, and then we can help recommend things, again, by starting smaller. I know, you want it now, you want to be louder than your friends. But, by taking a little time, you can REALLY blow them away with something that's not only loud, but is capable of hitting more than just one note.
So, here's what I'd recommend. Assuming, you have an existing system, I'd start with a pair of powered subs. Since you want to basically shake the house, look at a pair of 12's per side (way more than you'd need, but we'll go overkill route) in either a push-pull, or push-push configuration. Take a look over at Madisound Speakers and look at things like the NHT1259 or the likes. The speakers listed there may seem wimpy because they don't list insane wattages, but they can put out the power. This is where the power is needed, not in the higher realms.
Next, do search for some design software on the net, I know there are a couple that will allow you to enter a bunch of the speaker's parameters (called the Thiele/Small or T/S parameters) and will help you come up with the best box volume and style to get you what you want. In fact, it'll help you to do this first, then you can start to see how the speakers you listed match up to much better speakers. It'll also show you how big of a box you'd need to make them play as low as you want.
With all of that, you'll next want to build your box. This is probably where you should spend a great deal of your time. If you just slap together a box, you won't be happy. It'll buzz, it'll sound wimpy, you'll hate it. I suggest you find someone who knows how to do woodworking and have them help you out. A hint on this, building the box with a jigsaw and a screw gun won't cut it. You need accuracy to make this box.
Now, with all of that, and assuming you've actually read this far, its not really as bad as it may seem. With a little planning, and patience you can have something that will not only out volume your friends, but will also be able to cover the ENTIRE range of sound, rather than just that one note.
I just wish I could have a $2500 budget to build speakers, at 36, let alone 14!!!
Go big or go home ???
I started when I was 12 and slowly worked my way up to the big stuff. The first set of speakers I made were from some old pine drawers using drivers from an early 70ís floor model console. By the time I was 16 I made my own 3 way PA stack over six feet tall with 18" woofers, the whole shebang. When I was 18 I built a set of refrigerators that sound just like what you are attempting now. Yeah they were terribly loud but couldn't even get close to sound quality the two-way 8" set I made using little Radio Shack woofers & tweeters.
If someone is helping you design and build it may be a little easier (folks 'round here) and some carpenter's shop. I couldn't afford such luxuries and I did all the work myself, every time. I drew an income from it and it fueled my purchasing for more. I even made my own table saw by mounting a hand held circular saw into a large piece of FIR plywood. :eek:
Schaef is right, I think. I would not start so large as the project may overwhelm you and you may never complete it. Of course you may have access to lots of money and you can afford to get Richard Prior to build them for you, but where is the fun in that!
Congrats and good luck! Cheers to 14 year old speaker builders! That just rocks right there! :cool:
By the way, for 14 you are very articulate with language. Seems a little odd but who am I to say. :)
I am 13 and I wish you luck. I would be building security systems for the whitehouse but I'm underage and I still don't have that much of a grasp on electronics yet. I'd go with that "you don't want to blast the house to pieces" part. I put two 4-ohm car speakers in series for each channel and it sounds NIIIICE! It proves that you can have a redneck speaker setup and still have really nice sound :D . This might not be what your going for but it fits good for me. You should go for what is best for you without necessarily damaging your hearing. I suggest that you really listen to the skilled people on this site because that is what's going make your friends green about your system- good sound, and under $2,500. Keep going, and have fun most of all! :cheers:
If you are only 14, I'd like to give the advise to protect your ears. If you suceed in your design, you will not only **** off the whole block, you will damage your ears and not be able to enjoy music when you are older. Bigger and louder isn't better. For HT, 80-100 watts per channel is nice with a quality amp and speakers and a nice powered sub, but for muisc, the goal is clear, pure, and as realistic as possible.
Save your money, listen to the advise, and do not build the biggest speakers on your block. I've heard over 1000 watts before and all it does is make your body shake, it doesn't make anything sound better.
Well, I hardly ever turn up my current system up past -20db so I don't much care about exactly how loud the speaker's maximum is I just want something that's bumps hard. Thanx for the head's up though.
Okay, that's more realistic, and well, much more promising.
So, before I continue, my original post was not to try to discourage you from building speakers, I should also say, its cool at 14 to have to opportunity to build speakers. Also, I should have paid a little closer attention to the name, if punk's your game, then you don't really need extreme deep bass. There's not a tremendous amount there.
However, you didn't mention what you have now, that'll help in recommending where a good place to start is. I'd still say start smaller than the big massive system.
So, I'd say go one of two different ways.
1) If you have an existing system with main speakers that sound okay and don't really annoy you, then start with building a pair of powered subs. A pair of 12" subs will be give you more than enough low bass to make you happy.
2) If your mains annoy the crap out of you, then I'd say start with some mains. Your best bet, as others have mentioned, is to start with a kit. When looking at the kits, keep in mind that you'll add a sub later, so you're not looking for the mains to cover the low bass range, so don't look for them to go insanely low.
To give you an example of the kind of designs that give what you're looking for, I have a pair of 3-way speakers that have 8" woofers. I also have a pair of passive 10" subs all running off of a Denon Home Theater receiver putting out a max of, I believe, 65-70 watts. This is way more than enough to fill my house (1,100 foot cape cod) with music if I crank it up. Once I power the subs, the low bass will be way more than needed for the small room.
The main speakers, on their own, do a very respectable job of reproducing lows in a lot of music. I'm talking things like Nine Inch Nails, White Zombie and the likes. And that's from 8" woofers!
So, don't get caught in the bigger is better philosophy.
Here's hoping we can help you build a system you'll be proud of, and kick your friends into next week with!
