"Tech branding", bleagh. If it *sounded* like a Meridian speaker I'd care. My Magnavox TV (Funai) and General Electric dishwasher (Haier) just piped up and they both agree! We'll see what the B&O dashboard speaker in the so-called "Mustang" Mach-E says when I talk to it...
Re (3)#1, LG's website doesn't mention protocol or frequencies, and I'm too lazy to look up the FCC filing. Huge waste if they weren't the same as the sub's. Re (3)#2, better than half-price there: included! In return for the pain LG's remote brings to your eyes & your fingertips. "Ugly" comes from (of course) Old Norse -- "uggligr", meaning "to be dreaded"! But it works overall just as integrated with the TV, the speaker, and cable boxes, maybe even more so than B&O's remote requiring a downloaded app for the TV (when & if available).
Philistine that I am: I just read the Cliff's Notes for George Bernard Shaw's "Major Barbara" but still don't understand the Andrew Undershaft reference! And I wonder, if B&O "flexed its muscle", wouldn't it just make a mess on the dashboard?
