JBL Project Array 800/1000 clone

inrank · 11th September 2006, 12:33 PM

just seen these on the web, look very interesting, is it posible to do a clone of these? (either the 800 'bookshelf' or a slightly smaller 1000 floorstander (middle))

have not heard them, but i want a live, enjoyable and big sound.

say budget around £400ish

Obviously copying the box wouldn't be too hard, but you would need to have some skill in fabrication to make those horns. I know some people have used paper mache to make horns, that would be inexpensive. Do you have a link to some more information on them? You could always buy horns and mount them vertically, but I've (in my limited expierience) not yet seen a single piece two driver horn for diy.

You managed to find the most proprietary system to clone, hmm English humor is unbeatable ;-)

what do you mean?

anyway, they are not sold over here, dunno wether to go for somthing like this or my other choice, Silver Iris's in OB.....

As sweet as it would be to duplicate that horn configuration, I think for time/money/end result you will be way ahead with the silver iris. But if you need something to keep you out of trouble for the winter, go for it!

Hardest bit would be finding flares that look like the jbl ones.

Something similar in concept but more conventional looking would be acheivable using 'standard' CD flares and compression drivers.

It would probably be harder to find a good direct radiator for the bass / lower mids than the horns / CD's.

xo points are around the 800 / 900Hz mark and 8k I believe.

Good luck!

Rob.

Edit : Personally I reckon it's a waste of time building something with horns and then using a small driver below them. I'd look at the 15" version as a minimum. Anything smaller will be holding back the design imo.

Even using the 15" driver I'd still use a sub below. ymmv etc.

thanks, i think it would be easier to make a design that say, was 'inspired' by the JBL's, would the Silver Iris's be better value for money or even beter?

That's what I meant.

I've never heard an OB using conventional drivers, only electrostatics so cant comment on the silver iris'
