Default CHEAP speakers that will make me go deaf?

Looking to build some cheap speakers that will play EXTREMELY loud, and sound decent, if that's possible. Thinking something along the lines of having 8-16 drivers per speaker

I have a strong Crown pro amp that does 400w RMS x 2 @ 4ohms or 570w RMS x 2 @ 2ohms to power them, so that should be sufficient.

Any ideas of what you'd recommend as a project for me? Maybe doing something CRAZY like (2) 12" woofers, 8 6.5" mid-midbass and 4-8 tweeters per speaker? Just something INSANE that will make people stare.

I'd like to keep each speaker under $300 for components, if possible. Or if the price needs to be bumped up a little, that's fine.

Thanks!

how about pushing cue tips too far into your ears? that's a much cheaper way to go deaf j/k, maybe parrallel and series a bunch of drivers like this?

Whoa, that's a crazy project

I was thinking of going with a buttload of these drivers from Parts Express. They seem like a killer deal at $8 each if you compare them to the other 7" Vifa drivers from there:

http://www.partsexpress.com/pe/showd...number=299-493

I could run those for my mid-bass drivers and throw 2-4 of these in the mix for my mids. Do you think these look the same as the 7" ones listed above?

http://www.partsexpress.com/pe/showd...number=299-492

As for woofers, I have (2) MTX T4124 12" car drivers laying around that I could use. They are subwoofers but I could run them more along the lines of a woofer and not cross them over until higher up. Only problem is I really don't want to use giant woofers in these speakers. I'd like to keep them "thin" looking and MEAN. Tons of drivers that just intimidate people when they see them. I'm sure I could build the speakers to sound pretty good at 50+ hz since they are 7" drivers, and I really don't need DEEP bass.

I can't seem to find a killer tweeter that's inexpensive. I LOVE the Vifa ring radiator (have them in my Polk LSi15s) but they're pretty expensive.

Anywho, thanks for the reply and keep the replies coming!

THANKS!

I kind of want to make some crazy big speakers too. I saw a pair of Rent a Center speakers at my cousins recently and honestly the size and beastlyness made me somewhat jealous. His had 2 15 inch woofers, an 8 inch midbass and a mid range and horn tweeter.. I want somthing just as "manly" however, unlike his I would like it to sound good.

I have been going through the Parts Express online catalog and came up with a pretty decent idea of what I want. It would basically be a 3 chamber box. The bottom would house a single 15" Dayton woofer, the middle would house 2 Dayton 8" drivers and the top would have 2 5 1/4 or 6 1/2 and a tweeter.

I however have no clue on how to A. wire somthing like this, B. design a crossover and C. decide how big, Im guessing around 5' tall though and finally if Dayton would be the right choice for drivers. I guess it is pretty sick that I want to even birth somthing like this but...I am man, hear me roar!

By the way, this is my first time posting here. I signed up a few weeks ago so I could look at some different pictures and finally decided to post, nice to meet all of you and I look foward to getting "to know all of you"

Default D27 Veritas

Check out these speakers, they will rock hard with dual 10s and are 3-ways. And best yet, they sound great doing it.

If you want to rock and roll you could try these woofers 18 woofs

With this mid10" mid

And this tweet tweet

with this horn horn

It may cost a little more than you want but it's something to impress your friends for quite some time.

Thanks for all the replies, everyone. I'm looking for something more along the lines of MASSIVE amount of drivers versus say an 18" woofer. When I look at the Polk SRT system with it's buttload of drivers it's very intimidating and that's what I'm going for. I already own killer tower speakers (Polk LSi15s) and this is just something I'm going to do for fun. Want to build something with my shop tools and have some fun doing it. This will be my first attempt at building a speaker so I want to go crazy doing it!

Do you guys have any links to crossover building?

Any links to what all those numbers mean when you look at a driver's specifications?

I'm thinking of going 3-way and possibly 4-way, just to do it. Looking for info that shows how to make say 25% of the power go to the woofers, 50% to the midbass drivers, and 25% to the tweeters. That's not the power lineup I'm going to use, but information that would answer those questions.

As always, I thank anyone for their input and keep the feedback coming!

In this case, may I suggest using passive radiators?

As far as I know, you're really supposed to use two 12 inch PRs for each 12 inch driver. So if you had two 12" subs for the low, it would really look like 6 cones! Come on, you know they're not all powered, but do your friends?

INTIMIDATION!

By the way.. I'm more into the idea of a 'sleeper' system. Hide a dozen Tumults in an IB manifold, build a line array with pro mids, add some horns, then cover them with a nice floral print grille. They'll never see it coming... and never forget it.

Default Re: CHEAP speakers that will make me go deaf?

If you are looking for cheap go with

http://www.partsexpress.com/pe/showd...number=269-570

32 aside will get you good SPL especially at 2 ohms since your amp can handle that. $0.69

For the high end, try

http://www.partsexpress.com/pe/showd...number=270-011

http://www.partsexpress.com/pe/showd...number=270-041

http://www.partsexpress.com/pe/showd...number=280-062

The Pioneer buyout drivers have been discussed in a few forms in here.

Does anyone have any experience with those cheap piezo tweeters?

Cheers,
GM.

I have used the 7" Infinity woofers in one of my projects, and they sound great. I have not used the shielded ones, but they don't seem to go as low as the unshielded. One thing to keep in mind though, you will need a pretty big box if you want good bass extension with these woofers. You need about 3.5 ft^3 for two woofers to really get them going. These drivers may not work for you unless you can live with a really big box.

Those little 4" drivers are wonderful for the price. You could run a whole bunch of them in a line array and get very respectable SPL's out of them. For the high frequencies, try using a few of the Dayton PT2's in a line. They are relatively inexpensive, and sound pretty good. As for the piezo horns, they are cheap, loud, and sound like it. Personally, I would avoid them unless you want your speakers to sound like cheap PA speakers.
One thing you might consider is, use something like the Eminence LAB12 for bass and cross it over to a line array of the PE 4" widerange drivers at around 150 Hz or so. Then, cross the line over to another line of 2 or 3 of the Dayton PT2's at around 5 kHz or so. This should give you a full range system that will play very loud on a reasonable budget.


Cheers,
Zach
