What do the power taps mean?
Each loudspeaker can be set to one of its power taps, for example 6 / 3 W. Choose a lower tap for small or quiet areas and a higher tap for large or noisy ones. Add up the taps of every loudspeaker on a line: the amplifier must deliver at least that total.
Many 6 W ceiling loudspeakers are tapped down to 3 W, 1.5 W or 0.75 W in the field; in smaller or low-noise areas 3 W is more than enough.
Can I get the loudspeakers in a custom colour?
Yes. Bosch paints loudspeakers in any RAL colour to blend in with the architecture of hotels, malls, airports and similar projects. The paint is durable, suits indoor and outdoor use, keeps the EN54 certification and has a 3-year warranty. Tell us the models, quantities and RAL code.
Who supplies Bosch loudspeakers in Pakistan, and what warranty do I get?
Electronic Security Company (ESCO) is the only authorized distributor of Bosch, Dynacord and Electro-Voice in Pakistan, so every Bosch loudspeaker is genuine and comes with a 3-year warranty. Warranty is carry-in: bring the unit to an ESCO office and after inspection it is repaired or replaced as needed.
We supply, design and install public address and voice alarm systems, with offices and stock in Karachi, Lahore, Islamabad and Rawalpindi and dealers across Pakistan.
