Introduction

Horn tweeters


Recommended horn tweeters summary:

The following tables summarize the significant specifications of all horn, and high-efficiency drivers.

Notes:

  1. Most frequency range data is supplied by the vendors, occasionally without any tolerance specified. Where backup data (e.g. curves or independent tests) are available, the manufacturers' specs may be modified to more closely match the measured data.

  2. All other notes for Sections 8 and 9 apply.
