according to the previous X600 deal (still available in all colours) you can also get the 10% EOFY code from Present icon (bottom right of page) and stack it with 10% off newsletter sign up for new customers.
bringing it below $90 Delivered.
X500 does not have Aux in.
Motion X500 is like a taller X600 except the 500 has no tweeters and retail is $20 cheaper. it's probably more top heavy because of this maybe not great for outdoors as well since I hear the painted metal grill can get scratched up and looking miserable pretty quickly.
I think these are designed for indoor use.
I first thought the X500 was the bigger speaker but looks like not, it looks like it but the X600 is much wider so probably sounds bigger which is why it's more expensive.
