@mijostyn —
the LSA 20s are nicely made and that is about it. The engineering is very basic. Even you could probably master it. They are nothing special. This design has been drilled into the ground.
Really? And what design is that? Dynamic drivers with a crossover in a box? Perhaps you could dazzle us with your deep understanding of exactly how the crossover in the 20s is designed? I won’t hold my breath.
Because they all have different diversions from a flat frequency response curve they all sound different.
Well welcome to the real world! Maggies and Sound Labs don’t measure flat either Einstein. And any speaker that does would sound like crap in a real room, so you’re just chasing your tail in fantasy land there chum. You don’t like box speakers with dynamic drivers — we get it. But overgeneralizing the sound of the design and saying any improvements will be marginal is just ignorant and silly and provides no benefit to the OP or this thread.
