Dayton Audio DAEX13CT-8 Coin Type 13mm Exciter 3W 8 Ohm

Great expansive sound speakers from a large sheet of corrugated cardboard!!! it really works! Use an inexpensive mini amp-receiver--- the Dayton exciters will work with small amp output.

These things are very delicate, Broke 3 out of 4 that i ordered...pressing them onto a surface, then heard crunch and they quit working.....Although for the price these babies sound AMAZingDefinatly ordering more........
