[QUOTE="johnc, post: 126595, member: 2084"] OK. Please excuse the mess. Here is the amplifier... [IMG]http://img221.imageshack.us/img221/9903/71903911h.jpg[/IMG] The amplifier lives in the bottom partition of the one speaker. The pic is taken from above...I turned the speaker upside down, lifted the amplifier out and turned it over. The white cable entering the back of the box is the 220V power cable. There is an on/off switch near where the cable enters. Then there are two grey cables, also permanently connected to the amplifier. One is the input with a 1/8" jack plug on the end. The larger grey cable is 2 twisted pairs with output signals to second speaker - one twisted pair is for the 4" driver and the other is for the tweeter. The base has holes under each heatsink to let cold air in. There is a slot at the top rear of the amplifier chamber. The slot is 10mm high by the width of the speakerbox. I need to improve the ventilation. First step will be to make the back slot larger. [/QUOTE]
