KEF Q90 technical information


I'm new on this forum, but couldn't find an introduction page. Hello.

I've been given a pair of Kef Q90s from early 1990's, and I'm keen to restore them. They have shattered surrounds, splintered wood and two of the four drivers are buzzing and distorting.

Before I launch into it, I need technical data, and I can find NONE on the web. Can anyone help, or redirect me please?

Many thanks.
