What type of amplifier do I need?
The speaker can operate in low-impedance (8 Ω) mode or use the built-in 70V/100V transformer with taps from 3.75W to 60W. Use a suitable mixer-amplifier for 70V systems.
What is the recommended crossover frequency?
The Control 447LP is a two-way speaker with an internal passive crossover, so no external crossover is needed. Just connect it directly to an amplifier output.
How to connect the speaker to an amplifier?
Connect the amplifier output to the Euroblock connector on the speaker. Make sure the transformer tap is set to the desired wattage when using 70V/100V distribution. For low-Z, use the 8 Ω position.

The speaker delivers 90 Hz – 20 kHz with a sensitivity of 89 dB (1W/1m). This makes it suitable for background music and vocal announcements.
How do I clean the Control 447LP?
Use a soft dry cloth to clean the grille and baffle. The grille is powder-coated and can be lightly damp-wiped, but do not let water enter the driver elements.
Is the grille paintable to match the ceiling?
Yes, the perforated steel grille is paintable. Remove the grille before painting and use a fine paint spray to avoid clogging the perforations.
What is the coverage angle?
The Control 447LP provides a 110° conical coverage, typical for a 4.5" coaxial speaker, ensuring wide dispersion for ceiling installations.
