Agreed with Clifford Brown. Since I DID upgrade (and post) the Xover's in the M3 Turbo S, I can attest to the improvements made when the crossover becomes more transparent. I would imagine that with no crossover the sound would be similar (better) that what I am hearing now, which is much more attack/decay, much more weight of notes, an open airiness to the sound that goes much more verticle than before. This openness adds to the live feel of the performance, and at the same time sounding more natural.
I imagine these new speakers will really set a new bar for what is possible at this price point.
Oh, and as good as the upgraded Turbos sound, the sound improved with the addition of DIY High Fidelity products using magnet technology. I guess sound improvement never ends.
Good luck with the newest!....
