Hi Ze’ev! Everything went smooth, had little problem with vibration around 50 Hz at reference listening levels , but after tightening all the
screws problem gone. I bi-amp actively, using two tube monoblock amps for mid and high, two solid state amps for low end, and minidsp active crossover. I’m pleased with results a lot, compare to my DIY OB speakers, Trio 15 TB has more balanced, more spacious sound and less vibration. Bass extension really good for open baffle design, however I use it with two subwoofers, and love the sound even better. Also I love the look of piano black baffles, they fit my interior very well.
