Best upgrade for my living room after Beam 2

Hi All,

I just got a Beam Gen 2 for my living room (I’m living in an apartment, so the area is not that big) and I’m loving it. I want to improve the experience, so I want to get the Mini Sub or a pair of the ERA 100.

In your opinion what will make more sense to get first, unfortunately I can’t get both now.

I’m only watching movies or playing music, nothing really pro or specific.

Thanks for the help!
