Athena S3 (?) with one of their matching S sub bases. SCT system (?). Probably Chinese-made around 2000. Athena was one of API (Audio Products International - also Energy & Mirage) brands, which at the time was owned by Howard Hebert who became the biggest box builder in Canada in the 80s & 90s. He sold to Klipsch in 2006 - which in hindsight was a spectacular move for him & great timing.
There are some old reviews on their site:
