Hmm now I'm confused. Is there a reason to crossover lower than that? Avoid issues with localization? For a speaker like LS50 Meta that struggles more with bass I would've thought 80hz is already the conservative estimate. I've seen people on this forum saying they cross over at 100hz or even higher!80 Hz might even be a little bit high for the LS50. Your ears will know when you configure them.
No warranty. Gotta pay the full fat $1700 for that.You know... If it where me I would buy the R3s. They solve the height problem of getting the tweeter neat ear level, they are substantially heftier and they are a 3 way. $1245 is a good deal. Do they come with a warranty?
