Purchased them from Marty @ FHRX over east. Just did lots of research, looked at response graphs and read reviews and bought on reputation without listening to them. Risky, but damn rewarding. At one stage Alberts in Rockingham were stocking the entry level HAT speakers but not sure they do now, or if they're still around.

Marty is stupidly helpful and stocks so many brands that you just can't get locally. If you need a new head unit or sourcing anything else locally, go see Fabian at Westside in Cannington. Tell him you're from Perth-WRX and he'll look after you. Alternatively, Audio Precision has made lots of people happy from all reports. They have a couple of stores around the place. I picked up my Arc Audio Black sub from their Myaree store. Was actually surprised they stocked them.
