I’ve had my LSR305s for about since 2015, and I’ve loved them. They’ve been really great speakers to mix with but I’ve had a problem with the left channel resonating. I put them horizontal, which fixed the issue, but is not the recommended position for optimal listening. https://www.youtube.com/watch?v=gbb-IbeX5nA this video is hilarious to listen to it on my JBLs.
So, the 305p MKII’s are on sale for $89 (!!), bit the bullet, and are arriving Monday.
I tried to fix the problem with stuffing tissues behind the woofer’s baffle/waveguide, and it didn’t really help.
If I get time, I’d like to do a side by side comparison.
