I have to admit, when I received the upgrade kit for my Sony SSCS5’s I was more than a little intimidated. I bought a simple soldering iron and a 2 foot square piece of 1/4″ MDF to build the crossovers. Watched a few YouTube videos and looked at a couple of examples on audio forums. Long story short, I finished assembling and installing the upgrade kit. All I can say is WOW!!! I am absolutely in love and blown away by the clarity and transparency. These little guys perform! Blues, Jazz, Rock, vocals, all sound so nice! I plan to replace my 40-year-old towers with these upgraded Sony’s and an RSL 10S MKii subwoofer.
Thank you for the upgrade!
