I'm using these pads to tilt my studio-monitors. You could use this for a flat mount or two slightly different angles. Ofcourse, depending on which way you mount the speakers on the pads you could tilt the speakers upwards or downwards, depending on your need. Very good options. For me this pad was a bit longer than my speakers and a bit narrower. However, the speakers stand sturdy on the pad. There are different sizes available, so make sure to get oversized instead of too small. You could always cut the extra piece off with scissors if you will.
Very recommended and affordable product!
