No idea of the value, I'll find the article this evening.
I think there were two elements actually, the second to limit the lower frequency cut off, but in a very simple way.
No further trickery required!

If you think you know the answer already, you're not really searching

Colin's on his Tang Band project at the moment; I think we're more likely to see these than the Quads.

Yes I know, but that then means dragging the GM70 SE Monos to drive the Quads.......Aye I know,he's got plenty room in the car though!
I think the best thing to do is just ask if he can bring them along.

id quite like to have a crack at this too!
i dont have the desire to spend hundreds to find out weather or not this supertweeter thing works for me, but id def have a go for less than £10

from the maplins web site
This tweeter is designed to give a wide dispersion pattern and is therefore ideal in stereo hi-fi systems and in high quality disco and PA systems. Piezo tweeters are capacitative therefore automatically reject low frequency power and are inherently high impedance. Therefore, this can be wired directly across a woofer without the need for a crossover. Because modern amps can produce very high frequencies (typically up to 100kHz) it is recommended to wire a 47Ω 3W resistor (order code: W47R) in series with each tweeter to limit damaging high frequency resonance.

Just had a look at my piezo crossover 550NF cap with 33 ohm resistor in series with 22ohm across the piezo.I think I got this from the DIYAUDIO archive section a few years ago, seems to do the job .

If you do get some of these Maplin things, prepare to be get exactly what you pay for. The build quality isn't exactly monumental!
Oh, and if you screw them into a cabinet, don't overtighten them, because they crack easily around the mounting screws.

Thats right chris, infact some of the expensive ribbons are crap aswell.

Another thing to consider is getting a steep enough roll off as you go down the frequencies - those tweeters are working from around 4 kHz upwards.
If you cross over to them too low and with too shallow a slope then their effects will be all too audible. And not in a beneficial way.
