I recently upgraded my living room home theater to a four-sub setup, and one of the subs ended up in a spot where running cables across the floor just wasn’t realistic. When I came across the REL Airship II wireless system, I thought it might be the perfect solution Setup was super easy, and being able to place the sub exactly where it sounded best without any messy wires was a huge relief. But the real surprise for me was the wireless high-level input. I connected it to my surround speakers, and the difference was immediate. The sound felt fuller and more immersive, almost like everything “clicked” into place. I honestly didn’t realize how much I was missing until I tried removing the high-level input and then added it back again. If you’re using REL subs, especially if you love what the high-level connection does for music, Airship II is absolutely worth it
