Back in September 2018 I bought a set of Steg SQ650c drivers form an ebay seller named "Mazzone" , they are 6.5" mids (2) and 1.75" tweeters with seem like filters covered in shrink tubing but no crossovers , they had been stored since then but this week I really wanted to hear how they sound so i took everything to work and put them in two separate cardboard boxes and borrowed two pioneers crossovers that i had from another 5.25" pioneer components set, wired everything like you would in a car and powered them with a boston acoustics 2.1 powered sub i use at work ,so they are getting about 50 wrms each side , they sound really clear and can get loud without distorting . I did this to get and idea on what kind of sound they have since every driver i've tested this way sounds very different. The steg drivers did not disappoint me at all , better and cleaner than Pioneer TS-Z65ch which i need to get rid of since they sound empty and lifeless , cleaner sound than almost any component set ive heard from my own collection of speakers they are now my favorite out of all of them , they have a live sound to the with out hitting you in the face like a lot of speakers , or been too laid back like some other drivers , they sound just right. All of these with a boston acoustics 2.1 sub / satellite amp using pioneer passive crossovers , I can't wait to hear them running active on a pioneer 80 prs headunit and a 4 channel amp.
