These speakers were also at this price during October for their knockout sale, and are now on discount again.

Great for anyone currently shopping for speakers, or people who missed out on the last sale.
You can probably pricematch at Officeworks for a bit of further discount.
The next cheapest is Dicksmith at $129, according to staticICE.
