How can an integral amplifier ( HK 980 ) screw up a speaker's low frequencies ? bass dont work ...?

Hello At home I have focal 705 v & jbl ES 90 speakers but unfortunately their bass driver dont work now ...?

I believe this happened because of my faulty HK 980 amplifier s speaker one left output ... first jbl es 90 speaker had this problem NO BASS ... bass is dying when I use 2 speaker ON at same time I dont listen at high volume any way these speakers handle more than 80 watt there is no visual disturbance I hope there is a chance for these speakers (repair ) maybe they are entry level speakers but they are important for me I wont connect anything to speaker 1 output on my harman kardon HK 980 amp. Thanks to you

    The HK 980 is a well-respected amplifier which delivers 100 watts RMS. This may possibly have been too much for your loudspeaker.

    What you have to do is to connect a good speaker to your suspect output with the volume control turned LOW, and turn it up gradually, not more than half-way. That will tell you whether that channel is OK.

    Reciever 80 watt per channel my focal speakers handle 100 watt and jbl es 90 more than 100 watt BUT I didnt push them at all ... There is more complex problem with reciever :/
