I bought these CL 108 MK II tops as a replacement for the tops that come with the dB Technologies ES602 set. The 4 x 3" ES602 tops lack highs and have a plastic / nasal midrange sound and even though they are "OK" considering the price, especially with some EQ, they're not a compliment to the excellent 10" subs that come with the ES602 set. The CL108 are a perfect match for the 10" subs. The highs sound fresh and crisp and also mids sound great without any dominant nasal frequencies. I would have expected the tops to be a little smaller, they're almost just as big as B210D monitors that I have. Build quality is excellent, they feel very sturdy. Built-in handles are very handy. I also like the fact that the HF driver can be set to either 0 or +3 dB. As I was looking for more highs, I started off on the +3 dB setting, but was a bit too much so great I could set it back to 0 dB (which was standard setting out of the box). The weight of just 9 kg is also great to handle and is still just OK for the 14+ kg ES602 subs. I bet these tops would do great on other 10" / 12" subs with high pass filter as well. As their impedance is 4 Ohms, they will "draw" max power from your active sub or amp which is a good thing in this case. Excellent product, especially considering the price. Can't imagine how they can make it for the price. Matching covers for EUR 44, excellent! Well done Thomann!
