Hi All, thanks for the suggestions.
Just an update.
I went back to basics and read the manuals in relation to all the equipment.
Problem now solved.
Speaker cables plugged in + to +
- to -
There is an adjustment at the rear of the speakers for LF and HF, I changed both.
Speakers on one side about 2 m from one wall on other side about 1.5 away and about 3.5 m away from each other. Both speakers about 1.2m from rear wall.
Placed cork under speakers (feet) floor is tiled.
All sounds awesome. Bass pumping and clear sharp highs.
Thanks again for everyone's input very much appreciate it.
