I've owned my M4TS speakers for a couple of months. (They have replaced Buggtussel Amydalas, which I used [and still own] for 13 years.)
I am very, very impressed with my Spatial Audios. (Still siting them in my 13ft x 10ft x 9ft room. New positions for them every 3 or 4 or 5 days . . . yes, I'm getting close to screwing in the spikes. But, man, dialling in new-to-these-ears speakers is a lot of work!
Anybody who knows, please fill me in on why a speaker as impressive (at least to my ears) as the M4TS model - and as affordable to own - was discontinued.
Your insight will be very much appreciated.
