#19001 AIR SPEAKER SYSTEM PLANS
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.

#19002 MATCO SPEAKER SYSTEM
Great response, inexpensive, easy to build, what more could a music lover want? Build the cabinet from plywood, install about $50.00 worth of speakers (two 12" woofers, 8" midrange, horn tweeter) and challenge speakers costing 20 times as much. As a bonus we will include a publication on building speaker enclosures.
