DSPPA FLUSHMOUNT CEILING SPEAKERS 

Flush mount ceiling speaker with a 70v/100v transformer built in. The 70v/100v transmission is realized in a high-voltage, low-current mode, which makes longer distance transmission and parallel connection of multiple loudspeakers possible. The flush mount speaker is an ideal choice for industrial and commercial applications in hotel, school, office and factory where background music and paging is needed.
