Default DIY Speaker Less than AUD$300/pr

Looking for a speaker design that costs less than $300 au per Pair,
Sound is of corse most important,

the $300 includes:
  • *crossover,
    *Drivers,
    *Materials for the cabnet

Must be good at music (classical, Jazz), Movies, and be flat to 25khz (find Hi-Freq destortion annoying)
Must be Bookshelf, (little space)
Must have Bass for some movies but will have small sub,

Thanks in advance

Alexis Shaw

This is a very big ask, i usually find that cabinet drivers and crossover are about equal cost when I build.
If you can find any Vifa P13's then perhaps the DIY reference may fit the bill.

diyAudio reference speaker project

P-13's were about $90 each, add 2 tweeters @ $50 aprox.

If you wanted an open baffle floor stander then Jaycar have some really cheap drivers, but with limited power handling.
How big is your room and what construction??

Alexis I'd take Andy up on his offer, Rabbitz lives in Newky as well.
With a generous offer like that you should be able to turn up a winner.
That little Wavecor driver looks OK too.

Andy;-) I'm hanging on to the Jaycar Carbon woofer as I've sold off all of my KEF drivers.

Regards
Ted

Yo Moondog,

That's ok, Sorry for not getting back to you, a big Uni seminar I had to do, got in the way.

I have decided to try one of these Hi-ef things. Picked up some of the Selenium comp drivers that were DOTD on PE (I'll turn up some wave guides for them). Some Beyma 6MI80's as well. Gunna match them with a pair of the old 15" Jaycar PA drivers. (they are luvly drivers).
So I don't really need the 10's after all.

I've been thinking of trying that 5.5" Wavecor as well, but would want to use one of the small faceplate Wavecor tweets, so will wait until they come back into stock

Graph looks nice and flat, at 3000 I'd probably be using third order myself IF I was going to be pushing it, think that is system power handling; not the tweeter itself.
Good price
