Outdoor Soccer Speakers

[N-Brock]

A friend of mine asked me to build a pair of speakers for her soccer practice.
I wasn't really sure what to recommend or make because i have only made indoor speakers. So i decided to turn to the all powerful DIYaudio
I know a lot of people are really into good sound quality here but mainly i need to focus on it being loud and cheap. I would like to keep the cost under $150 but i know it will probably surpass that.
So far my only idea would be a big PA style speaker set. Also this will most likely be sourced by an iPod so a huge frequency range is not necessary.
The speakers will be brought inside after practice so they will not be damaged.

Thanks

Hi
here a couple of project idea's to get you thinking...

Low cost 3 ways that s/b close to your cost goal, not hiFi or PA, but should be loudish. The woofers are discontinued but he points to another part for a substitution. If you want to do something like this, best recalculate the enclosure size before proceding to cut wood. see link below

There is another project that is more PA (really loud), but the cost is more.

The second project, the Blue Wonder, uses a horn the H07E. The project talks about it being a good horn for fidelity over volume. Do you think that this is still a good choice, or has it been eclipsed by say the round dayton waveguides?

CD waveguide sizing makes a difference esp if trying to cross a compression driver to a lower x-over point. Which prob. not a factor here for a 3 way. But would make sense to use the larger one for a 2 way using a 12" or 15" bass driver, which is the way to go for some. IMHO I would use a 2-way design allowing more $$ for a better compression driver giving up a little low end bass as well. But I don't have a design yet.

Those Dayton waveguides suck. Cheap though.

I think the "buyout" 12" coaxial is still for sale at PartsExpress, and there's even info for a fairly simple passive xover design. They're "cheap" at under $100 each last time I looked. Might have been made by Eminence, not sure though, but that compression driver definitely looks like it, as does the rest of the driver. However, unfortunately, Qts is high at .75.. 0.8 Qtc in a large 4 cubic ft sealed enclosure, and you still won't get much below 70 Hz. So, that kinda spoils it all really. If it weren't for that alone, it might be my recommendation.

Anyway, something like that was the first thing that came to my mind.. far from optimal, but easy to do, cheap, less cutting, smaller, etc.

edit:

Oh, also!!.. I forgot to mention.. there's been several buyout items in the PartsExpress pro drivers section with really good prices. I recently got 3 of the Eminence Delta Pro 12's..

One of the 10's already sold out several days ago and isn't listed any longer, but here are the rest that are still available:

Why is that?

[BHTX]

I borrowed the 12" version (seems to have recently been discontinued for some unknown reason) from a friend a while back and tried it out with a DE250 (all I had at the time). I didn't save the few casual measurements I did, but I gave it back to him preferring the other two horns I'd been playing with at the time quite a bit better.. an RCF H100 and the 18Sound XT1086. Anyway, I hadn't come across much good about them either, even before then. Negative comments is about all I've ever seen, but the majority of it is mainly in regards to their flimsy cheapness and lack of rigidity, which I agree with.

thanks for the info BHTX
They (dayton WG) seem a little too shallow in the larger sizes, not sure if they stick to the same geometry or not. Have you tried the dayton 7x7 eliptical?

Still using the DE250 & where do you X-over?

[dnsey]

Have you considered a Bessel array?

If you can find a source of small, cheap drivers, they are a definite possibility, having the advantage that you can design them for whatever polar response you prefer.

Why not tell her to purchase some Peavey PR 10's or 12's ?
