\rBob,
Thank you for you question. Yes, the AP525 70v version will provide good clarity and volume. They have 70v taps for 2.5w, 5w, 10w, 15w, and 25w. Thus, you would need a 70v amplifier that provides anywhere from 25 watts to 225 watts depending on how loud you wish to have them. If using our PA90 70v amplifier, it pushes out 60 watts, so you would need to set each of the 9 speakers to 5w or less. The 70v version is $10 more than the standard 8ohm version. We are located in California and can ship same day as long as the order is placed before our 3pm cutoff time.
