Feonic F1Pro Invisible surface mounted speakers (x2) plus amplifier

Kit with 2 Feonic F1Pro speakers plus amplifier, cables and mounting plates. Speakers are 4 ohms each. They transmit sound through surfaces, so table-tops, doors, windows, anything that will resonate well (e.g. a window or a door works well, but a concrete floor does not). Adhesive pads are available on request. The adhesive pads will allow the speakers to be affixed to windows.
