Review: Don’t second guess it - My only con is that they don’t handle as much power as the woofers and tweeters from this same set. The woofers and tweeters handle 100 watts rms, while these handle 75 watts rms. However, I have yet to hear them distort and I’m sending 300 watts rms to each channel (so they are theoretically getting 100 watts rms). On top of that, the sound quality actually gets better, much better, once these are included. I didn’t think the 2-way could improve…

### ⭐⭐⭐⭐⭐ mounting holes are 4" center to center with about 1/8" of play as the holes are oblong.
*by M***X on September 3, 2018*

I used these mid-range speakers in a set of Rogers home speakers that had a weak sounding mid range sound. These Kappa speakers fixed the problem far better then I though they would. They are amazingly clear and bring out vocals, Piano and all other sounds in that range very realistically. I would recommend these speakers to anybody that is looking to improve mid-range performance in a hi end stereo system for car or home.
