I've bought used for their prices, their robustness and acceptable to mix sound.

SOUNDS

It lacks a lot of bass, it is ok but small even compared to other speakers of the same size they are less good at the bottom.
I find the overall effect quite aggressive, useful for mixing but tiring.
The lower medium is little precise.

OVERALL OPINION

A strong point is the sturdiness, I'm not afraid to move, no need to mettres in a cardboard box, bubble wrap, foam and all the stuff to carry.

At bargain price, this is a very good value for money. By against nine I think there is more in the same category.
