Description
Thank you for purchasing the PRi series CV speakers. These speakers incorporate high-quality components that
produce the famous Boston sound. They are housed in a metal enclosure that makes them easy to install and
meet the stringent requirements of electrical codes throughout the country for plenum-rated enclosures. Such
enclosures are often required by building codes in commercial applications and residential applications such as
townhomes or condominiums. They have built-in transformers for use is constant voltage distribution systems—
either 70V or 100V depending on the country in which it is used. So they are ideally suited for multi-speaker
commercial installations.
The bass drivers in the PRi models have a DCD mica-filled copolymer cone with a butyl rubber surround. An inte
-
grated, forward-facing tuned port extends bass response. The soft dome tweeters of the PRi665 and PRi685 have a
pivoting mount. Insulation inside the enclosures helps control resonances and improves room-to-room isolation.
