Hey guys and gals, as shown above, I have pairs of both the Sony SS-CS5 (Mark 1) and the updated Sony SS-CS5M2 (Mark 2) bookshelf speakers here at home purchased through the usual retail outlets. As you might know from discussions online and videos on YouTube, opinions can be quite polarizing regarding these speakers. I think it's a combination of the low price (with associated biases as discussed recently) and the unusual "super-tweeter", 3-driver design. In this post, let's have a look, discuss, and go over a few measurements based on what I see and hear with these transducers.
For convenience, throughout this article, I'll often use "M1" and "M2" shorthand to refer to these Sony SS-CS5 variants.
