I have my Wiiim Pro set up in my bedroom and really love it. I have just built an outdoor inground pool and have purchased an outdoor speaker system with landscape speakers to include 2 buried subwoofers. I am powering them with 2 Sabaj amps in a monoblock configuration. I plan on installing a Wiim Pro through a Sabaj Preamp/DAC. The equipment will be outside on a covered deck to protect it from the elements. The pool is about 15-20 yards away from the Wiim Pro. Is that distance adequate to control the Wiim Pro from my phone? Any suggestions would be appreciated.
