I have previously posted these and they were $115 back then. An absolute steal at $75 or $63.75 if you use Afterpay and the code APAYDAY.
Just buy a cheap 5.1 AV receiver or even better, pick up a used one from FB marketplace or Gumtree etc.
Only 11 left in stock. at time of posting.
They also have a number of centre speakers with an extra 40% off as well. https://www.ebay.com.au/sme/hificlearance/Save-up-to-40/so.h…

A review from 2003. These are older than my missus AND side missus.
