Acoustically measure with REW and a microphone, the room gain ( boomy bass) will be immediately obvious, use the ‘EQ’ function of REW to create the requisite filters, tight bass with no boom.So, I've had these for since July and I am again not quite happy with the sound and I am pretty sure I know why and it isn't per se Ascilab's fault.
They are quite boomy in my LP shelf near a back wall. All bookshelves I've owned, which isn't more than a handful were, regardless of the apartment/location they were in compare to my main floor-standers that are out in the room a bit. How much baffle step correction are baked in? Were the measurements done with the speakers on stands out in the room? Ostensibly I can correct this in my WIIM Ultra, because they aren't bad, just the tonal balance is way off
