Tuned Resonant CW SPEAKER - open baffle - using a 4 inch woofer laying inside an aluminum WOC Lid

[Chuck aa0hw]

brief demo of a resonant CW SPEAKER setup using an ALUMINUM WOC LiD that the XYL was going to throw away...

and a forgotten 4 inch sub-woofer i purchased from RADIO SHACK back in the late 80s...

turns out the combo performed well as a RESONANT CW SPEAKER

and was much louder in volume than my bookshelf radio shack speaker
