Brian gave me a try of his supertweeters had a wee play about positioning wise. firing vertically velcroed to the 57s they seem to do the business.
he never got them back-57s are singing....

Excellent Tony :D
Which ones did you use?Quote:

They come from japan and were about 50 quid but Brian got stung for import duty this time round to replace my ones so mid 60s.

Misterdog (PFM) had a set of small ribbons on his, he's recently swapped them for a set of ADAM's AMT ribbons. Both had the effect of lifting the height of the speakers. Call it a broader sweetspot, more diffuse, less focussed. I doubt it's more accurate in terms of lobing, defraction, timing etc, just an easier listen in terms of accommodation.
Anyone??

This shows how to calculate for an entered value of required attenuation

With a constant impedance L pad 'volume control' it is impossible to measure the resistance to ascertain the attenuation, as the impedance is designed to stay constant.

Looks like a case of laying in a few cheap resistors to experiment with. :)
