The PE26I enclosure is based upon the success of the PE6I design but with a few extras. We have added a second 6 1/2" woofer which operates under 200Hz. It reinforces the low end so the PE261 is flat down to about 60 Hz. The alignment and imagery is perfect, making this the ideal cabinet for a variety of applications. Just like its little brother, the PE26I comes with several threaded templates already built in and ready to adapt to a variety of permanent installation requirements. On the back it has a 4-pt. threaded template which fits the Omni-mount 30.0 series wall-mount, or ceiling-mount adapters. On the bottom, there is a template for the Ultimate-support speaker stand mount. On the top and bottom is a single point mount, which will fit a U-shaped bracket for horizontally mounting the PE26I to a lighting truss or for under balcony applications. Both cabinets come in an environmentally safe Water Borne Polyurethane Paint finish which is Ivory white in color. This finish is easily repaintable if the installation requires specific color matching.
