That's good to hear about adding a sub! Will be interested in your solution.I see. The rears on the LG are as effective as my separates if I am being honest. I have now almost found a permanent solution to adding my Active subwoofer into the mix which means I don't have to worry about the missing infrasonic deep bass and this solution should apply to any soundbar.
How is your Q90R fairing in comparison to your ex-LG SN11 ?
So far pretty well. I still think the bass was better and more full with sn11rg, and the level of immersion (more active rears, wider front sound stage) was better. The center channel is a little more crisp and dialogue is more reliably clear with the q90r. It does a good job of immersion, enough to satisfy my needs. I took down the treble and the center channel a notch or two and turned up the rears by 2, which has helped. It’s just not quite as accurate or detailed with sound placement, at least in my space. Thankfully Dolby vision passthrough has been working just fine. I must’ve had a defective unit or bad cables before. I haven’t really put it through it’s paces to test for pops and crackles. BR2049 on UHD sometime soon for that. Our tv stand looks a lot cleaner and the wife is happy so that’s been worth it
