Both our ST-100 and ST-200 supertweeters come supplied with an alignment gauge and a list of alignment settings for all of our Hi-fi speakers dating back to the 1950's which advises you how to use this gauge. The ST-100 is a universal supertweeter and can be used with any passive cabinet, however, unfortunately we cannot provide placement information for non-Tannoy speakers and we can only recommend experimenting with position until you find the placement that best suits your listening environment.
