I tested this two subs few days ago it did a super great job in a combination with satellite speakers(2x Ev-Zlx15p) People were dancing all night long, no sub-bass error or failure so ever . It was a bit hot at amplifier area, but no danger in overheating.
To protect yourself I advise you to run it via speaker management system, for total cross-over and limitation control against potential misunderstanding of mixer's master output signal that could damage your entire system.
Otherwise Frequency cutoff works very well this sub is playing very very loud and comes with a built-in limiter.
As a good Sub its heavy and it should be!
Its well built ... but don't hesitate in buying 4 wheels for transport your back will be very thankful, this sub will expand your bass-based-music delivery for all thirsty dancers out there. Totally recommend!
