I wouldn't try to over drive these but for the money it's a good deal
We used two behringers and two seismic audio subs (15s)
I had purchased a Behringer PMX3000 mixer some years back and it pairs up with these speakers nicely
Despite some of the negative feedback we saw about these, we purchased them to try them because Behringer's studio mixing boards are so well-made and excellent
i would suggest anyone to buy speakers with built in amps instead
