8" Public Address Speakers
MCM Custom Audio provides a wide range of ceiling speakers to suit most commercial paging and background music
requirements. Their standard 8" size and good frequency response also makes them ideal full range replacement drivers
in low cost speaker enclosures. #555-6381 feature moderate power capacity and are ideal for most background and paging
situations. High efficiency, high reliability and low cost make these the contractors choice, especially in systems requiring large
numbers of speakers. When wider frequency response is important, #555-6386 feature two-way design, providing highs up to
20KHz. For more demanding foreground music applications, #555-6390/6391 feature a large 17 oz. magnet and treated cloth
surround, providing 60W peak power capacity and increased bass response. All models are available as standard 8ohm or with a
pre mounted 70V/25V transformer. Each is compatible with standard ceiling baffles (#50-150), T-bar supports (#80-1350) and
surface mount wall baffles (#555-915).
