No, it's just the name 'Bass trap' I have a slight issue with. A lot of my friends have home-built wide-band absorbers like these. But they aren't bass traps. They'll go down to lower mid/very upper bass frequencies but need to be a lot thicker to start touching the real bass problem areas. If you have an issue with bass frequencies in a room (i.e. just about every room), then these aren't going to touch the bass frequencies enough to make much of a difference. Very useful for mid and high frequency absorption, and every studio should have some, but they need to be thicker, located further away from the wall and should ideally be located in the corners to start touching the true bass frequencies.
