The twins have a shelving control for both the bass and the treble. These are powered monitors with balanced line level interconnects, but they can be set to higher gain if desired. I run them through a sub 6 powered subwoofer which also has a bunch of cross-over controls, gain, low pass, high pass, phase, polarity.
I originally ordered the Twins without the sub, but wasn't able to get the bass I wanted, mostly because around 80 Hz there was a room null with the positions I had to use in the room. When I added the sub, I could move it around. After a lot of effort with an RTA I got reasonably flat response with no nulls in the bass. I was still stuck with some room mode peaks, but I took these down with a parametric equalizer and while I was at it I boosted the bass around 28 Hz a bit. In the end I got flat response down below 30 Hz. Once I got this balanced out by measurement I just played with the treble controls until a collection of reference recordings sounded good. Getting the highs to sound right was not hard in my room after I dealt with some reflecting surfaces. It won't be possible to get low bass (20 Hz or lower) out of the 11 inch sub, as I found by bottoming out the driver in one sweep test. I was able to hear 30 Hz without doubling.
One thing that is a little quirky about the Twins is that both 6.5" drivers run together for the lower midrange and there is some uneven response if you do not sit on axis. This is fine with my setup. These are near field monitors and not intended to fill a room.
The Focal twins come with integrated plate amplifiers, three per speaker. The bass and mid amps use variable voltage rails for power efficiency, but the tweeter has 100 watts of class AB which creates the heat, making it hard to leave your hand on the metal back panel for a long time.
