In terms of sheer units sold per year, what is considered a lot of sales for a specific speaker model? Obviously, different companies have different sales goals based on all kinds of factors, but I was just wondering, how many speakers are sold per year for (seemingly) popular models, like the Elac Debut, KEF LS50, Klipsch ps-600m or the JBL L-100? 10,000 pairs? 50,000 pairs? I have no idea. I'm just curious. Maybe there is no simple answer.
