| You can buy the transformers seperately on line. The taps on the transformers determine the wattage, not the speaker! So if you tap the the transformer at say 2.5 watts at an 8 ohm load assuming thats what your speakers are. You will need 19 speakers x 2.5 watts = 47.5 watts total. A 100 watt 70v amp will do it easily. Most transformers will have taps from .5 watts to 10 watts. Don't let the small wattage fool you, the speakers should still get a decent volume. |
