Abstract
Interference between sound waves of different frequencies in a speaker system having a woofer and associated transmission tube are eliminated by securing a sound absorbing diaphragm to the output end of the tube to absorb sharp and high frequency sound waves while permitting low frequency sound waves to be transmitted through the diaphragm.
