For treble response there is a 1-inch silk dome tweeter with a generous-looking wave guide, and this design should widen the tweeter “sweet-spot” quite a bit, and help blend sound from this 2-way (or perhaps 2 1/2-way) design.
Of course, none of these impressive specs come cheap, as the MTM carries a $499 USD price tag. Powered monitors are a crowded market, but there seems to be enough in the way of features to help set the Monolith MTM apart. I’ll be reaching out to Monoprice to see if they are sampling these new speakers to media, to hopefully see how well executed this new product is.
