Thought I would resurrect this old thread as I own and use two ABM210H Pro Neo cabs with my ABM600
Rehearsals ( mostly loud rock ) I use both cabs stacked and due to the design ( diagonal speakers ) they make a tall rig ( probably a 610 cab height )
Are they good, yes I believe they are but you need to get the EQ right to really make them sing.
Probably don’t have the very low bass sound of a ported cab as they are sealed but they do have a decent amount of low end and mid punch.
300w rated but could they handle that power it’s hard to tell.
Weight and carry is amazing as they are so light. You can carry both cabs together ( one in each hand )
They are a small sized cab ( personally a bit wider would of been perfect ) but they make a neat stack.
Im sure you can find high end cabs that would be better but for the money and how they perform I think Ashdown got it right.
As an experiment I got an older U.K. Klyston 115 cab to compare them ( ported cab ) and the ABM210H sounded better as was more articulate and better punch. The Klyston I know was a 15” so not a fair comparison but it just sounded flubby in comparison!
