Conclusion:
Sound is clear, accurate and non-fatiguing. I am very pleased with these in a near field set up. A perfect match with a Tang Band W5 subwoofer and Dayton DTA-2.1BT, although I would be please with them in this set-up without a sub.

About the Designer:
I have always been an aspiring audiophile, although I don’t consider myself one. I am just a guy that loves music (listening to and making it), movies and building things out of wood. I still have my Infinity SM-62’s I bought out of a Crutchfield catalog in the early 90’s (~14 years old).
