Thanks everyone for your input Let me correct one thing, the 151s are 151se new speaker round half moon shape with three speakers articulated array they produce a stero everywhere sound 5 year transferable limited warranty, test for 1,200 hrs with a salt fog test.price 289.00 the 131s 228.00 being placed by knees would they still produce the stero everywhere sound and would they have a good base, for the extra money are they worth it, or Hey if I'm going to spend that much what the heck?
