If you have a set of KEF Q300's I have a huge favour to ask. I have happened upon a set of drivers that are used in these speakers, and I would like to build a copy with my own enclosure. What I need are some measurements, and a description of the internals. In order to do a copy I need the X-over specs, the volume of the cabinet, and the length and diameter of the base port. If you are able to provide this info for me I will be very grateful. Any help is appreciated. Thanks!
