I see the amp is rated at 50 wpc.@8ohms. The way they post the spec makesme believe that 50wpc is questionable. I would not look at any speaker with less than 90-91 db sensitivity. 93+ even better. So far, none of the speakers except the Tektons are a decent choice for your amp. There are other mfg’s who make high sensitivity speakers but I can’t think of any right now. You will have to look at the sensitivity rating. Anything below 91-92 db is not going to be very good. Don’t look at the speaker mfgs rating on "Recommended Amplifier Power" Sure you can get some sound from an 87db. But your amp will be near distortion (clipping) when playing
BTW, Here is an example of the specs I was speaking about. Look at the Recommended Amplifier Power" and you will get some understanding of what I am speaking about
