PLAN19000 - 2 Watt Audio Amplifier ... $12.95


In order to recreate sounds, a speaker system must pump a lot of air. Ordinary speakers are very inefficient air pumps and therefore the response range is limited. OUR speaker design was engineered as a good air pump. Provides response from almost 0 HZ to 25000 HZ. Compare that to those expensive over-priced commercial units. Can be driven with just a few watts and exhibits output powers challenging the biggest 500 watt speaker systems. Ideal for small rooms or the biggest halls.
