Summary: I have 4 P153s in use for my L, R and Rear-L, Rear-R surrounds. They are in grouped with my Infinity Primus 300 series floor standing Front Speakers and PC251 Center Channel. Since my room is only about 12'x22' in size - I didn't think the 163 series surrounds would be necessary.
Pros: - Clarity - Punch - Look good
Cons: - Box is a little bigger than I'd hope for. A little large to use as mounted surrounds in a smaller space.
Summary: I purchased this product for my studio apartment's home theater. the P153 delivers a strong sound fidelity even at higher volume while playing music. I would recommend this product to anyone who is looking for decent sound at a moderate price.
