On the back there are various settings to adjust the sound to the given premises. This can be very beneficial if it is not possible for example in the home recording studio to set up the boxes in the open field. The various setting options are outlined on the switches, which greatly facilitates the correct setting.
The sound of the TRUTH B2031A is powerful in the high and mid frequencies and clear but relatively washed out in the bass range and not defined exactly to my mind. For working in bass relevant genres like hip hop or techno, it is advisable to supplement the studio monitors with a subwoofer, which is easy to implement by lowering the low frequencies to the B2031A's also.
The panoramic image is Behringer well managed in these boxes. Elements that are distributed in the stereo field, can be clearly and precisely places.
A big drawback for me is the reproduction of the signal depth .: it turns out to be extremely difficult elements to the rear position, because you can never know exactly exactly where they are.
In conclusion remains to say that - despite imprecise bass and poor signal depth - the TRUTH B2031A are distinguished by their good price / performance ratio. You are competing in a position with other studio monitors and who will not invest too much emphasis on precise bass and precise signal depth, is with these studio monitors have a lot of fun.
