At home I have a set DML panel speakers set up in a 2.1 channel system with a subwoofer. The panels themselves are made of EPS polystyrene that has been sanded down and coated in wood glue, are about 1 meter tall, 30 centimetres wide and 2 centimetres thick (3 foot 3 inches tall, 1 foot wide and 4/5 inches thick) and have rounded edges and corners. Each panel has a Dayton Audio 10 watt exciter mounted to it on the location recommend on their website. The subwoofer is a ported down firing unit, which I have placed in the corner of the room for corner loading.
