Just an update on my Coastal Source Razor RZ310. After shopping around, I opted to buy from Crutchfield, as their quoted price was a fraction of what dealers wanted -- all of whom also wanted to install at absurd prices in addition to their absurd mark up. Also bought the Coastal amp. It is designed to be used inside a Yeti cooler, believe it or not. I put mine in a sheltered rack (it is rack mounted) inside a cabinet. Hooked it up to an Arcam streamer/DAC I picked up at Best Buy on close out, then hooked that up to one of my Wifi nodes by hard wire.
The speakers sound wonderful, lot of clean sound and base. FWIW, the only song that sounded "muddy" compared to my well-treated listening room (with giant SVS Subs, and Bowers 801D4s, dual mono amps, Nagra HD pre, etc) was the drum track on "Hot for Teacher". So, no, they are not "listening room" good, but they are miles beyond any other outdoor speakers I've heard.
Install does take some work. They are very heavy (50+lbs) and I was mounting to a concrete wall covered in stucco. There are a lot of sturdy mounting options on the back, but (due to mounting in literal blast shelter concrete -- not joking) I opted for two French cleats for the back to spread the weight out. This worked very well. Holes line up perfectly to Home Depot french cleats.
Wiring is proprietary with a screw down cap and male/female ends (bit like you'd see on an electric menorah or maybe a Christmas tree) with separate wiring required for high/mid and subs, so either buy the connectors that let you do this with a jewelers' screwdriver or know how to do butt-to-butt connections with a heat gun. I opted for the heat gun approach.
The other end at the Coastal amp (takes a 4 channel 800W amp -- very hungry) are Phoenix Block Connectors, which were new to me, but super easy to use, although seemingly upside down, so you have to keep your wires labeled and double-check you aren't doing it backwards. (I almost did, but caught myself.) Definitely worth getting UV rated/wet area outdoor 4 strand wiring for speakers online and not trying to Home Depot the wiring.
