Everyone - thank you all for the input on my quest to keep tweaking my Maggies and my new Sub system from Duke.
i have reviewed the multiple YT recommendations and I agree that I may make more gains in my sound looking at better speaker isolation and room treatments - I am going to abandon the idea of limiting the low frequency (under 150 hertz) going into my Maggie 1.6qrs. I feel ‘as is’ that the system sound has integrated very well - I guess my reason for concern started when I saw some minor delam of my copper wire ( 4 spots near the buttons on the panels about 1.5 in in length) on the back of my 1.6qrs and considering their age (18 years old).
I am very happy with my sound after the addition of The Swarm.
Again - thanks for the education.
