Eminence Delta Lite Neodynium PA Speakers

The purpose of this design was to create a quick and dirty DIY project that meets the needs of the semi-pro sound tech.  This speaker was specifically designed to be used in conjunction with 2 labhorn bass cabinets.  It can also be used with the double stack lab12 project for more portability while still retaining the ability to rock small venues.

The thumbnail set shown gives the basic design diagram.  It is not a "manual" for building the speaker but rather a conceptualization.  The neo can be used with any type horn lens and compression driver although the PSD 2002 is recommended.  In future updates an appropriate crossover will be posted.

Eminence Lab12 Doublestack Subwoofer.

While the Eminence Lab12 driver was originally designed for the labhorn sub (lab1, lab2).  It makes a great driver for many other configurations.  Presented here are two PA subs in different configurations with the same specifications.
