Customers often lack this awareness—where should they get it from? Especially in leisure facilities, which are legally required to have a voice alarm system, acoustic measures for speech intelligibility are indispensable. Make it clear from the start that speech intelligibility is a measurable metric that you should definitely pay attention to. And very important—you probably know this, but not your customer—speech intelligibility is not only the acoustics of the room, but also the interaction between the microphone and the speaker. You don't need to defend yourself here; just propose a better solution confidently.
Don't limit yourself to 100-volt PA system. Make it clear when you need more power
Yes, 100-volt technology has an excellent price-performance ratio. And even if modern 100-volt speakers have already improved significantly in terms of sound quality, they are not optimised for medium and loud music. If you want to play music that is more than just a quiet background noise, you need PA speakers with low-impedance technology If music is an important part of the concept of the leisure facility, for example in many indoor sports facilities, the speakers should definitely have a 2-way bass reflex system. PA technology rarely makes compromises. Offer low-impedance technology if 100-volt technology is not enough, even if this increases the budget.
