The ABM 610 was only $150 more at Sam Ash. I got two and they sound like my old SVT cabinets. They weigh about 115 lbs.,have dividers between each pair of speakers. They are constructed of 3/4" birch plywood. These RM 610s look good on paper (except the wheels are too close together). How they got the weight down is a mystery to me.
I just checked Ashdown's website and the weight on the ABM 610 is 38 kg which is about 84 lbs. Still very lightweight for a 6x10! I'll never part with my Bergantino NV610 but it lives on our band bus and I may have need for another big cabinet for a future project. This may fit the bill.
