I agree with Fansastic. 18+19 is just not as convenient as a single, full-range speaker such as BL20. Plus, from a performance standpoint, B&O makes no easy way to roll the 18’s bass down and let the 19 take over other than using Transmitter 1 over WISA with its built-in 120Hz crossover. And we all know that many people experience problems using T1 with WISA.
Without the T1, you can still use the 19’s controls to dial in where it begins playing but the 18s will still continue playing full-range.
Plus, I just like the minimalist nature of having fewer components on the floor.
So I look forward to a full-range speaker that looks nice!
