Yes.

Gee. That was easy.

If you have the 150 with the square baffle, you can either slip something under the front edge of the speaker to angle it up and, thereby, put your tweeter more on-axis with your listening position, or buy a speaker stand to get it off the floor -- advisable -- and angled up.

If you have a 150 with an angled baffle, just position it so that the baffle is angled up. However, it is still worthwhile getting it off the floor.
