I am looking to upgrade my backyard system. I currently have Apollo MTMs that are not cutting it. My plan is to have four 18s for subs and 12” tops (either coaxial or waveguide). These are not just party speakers as I would like to do critical listing so sound quality is #1 But of course I want the ability to crank it. My budget is around $250 per sub driver and $500 per top. I have two NU6000‘s to power the subs and a XLS2500 for the tops. I would rather go passive for the tops but I have not found a kit that will work for my application and I am not good at crossovers. All drivers will need weatherproof cones. They will be out of direct rain. I have a front yard system that has four PA380’s and two HTM10s that sounds very good but I want better for the back yard. Listing to music out in the open with no walls or reflections is as good as it gets. I’m in the county so neighbors are not an issue. Please given recommendations. I am leaning towards Faital drivers as they are mostly waterproof.
