I have a 65-inch Harmony (G1) with 4xBL18 and a BL19 from 2015. The whole package is sitting in my ex's house and they will be moving soon to my new place. A few weeks ago I found a good deal for 2x BL9 and I went to pick them up after listening to them.

Now, judging from the specs, I wonder if I made the right choice. My plan is to use them as front speakers (obviously) and keep the BL18's for side and surround in a 7.1 configuration. My question is related to the presence of the BL19. If I take the bass out of the equation (which will be redirected to the BL19, I assume), will I experience better sound than the 18's as front? Or should I just sell the BL19 and use the integrated sub in the 9?

I know the right answer is "try and find out :)" but I wonder what more experienced users (you) think in terms of what I should expect. Should I be prepared for the BL19 to be redundant?

Also, it's important to note that the previous living room was quite big (the 18 front L/R were 8 meters apart) and you could feel that the 18 were a little lacking in power for a 50 m2 living room, while in the new setting they will be 3.5 meters apart for a much smaller room (half I'd say).

Usage is 80% Movies/TV and 20% Music.
