I too had the 11’s for a week and decided to go the 19’s...was very impressed with the 11’s and in my room they would have worked wonderfully...but stepping up to the 19’s/sound anchor’s...wow...get the pro driver and just everything is just a another level...highly recommend...oh and i would have always wanted and wondered about 19’s if i had the 11’s...With your amp...would think quite pleased.
I think the biggest advantage of an active powered speaker is there is none of the mismatching of components to the speaker...it "perfect" match...and yes that is very desirable...but I do think the passives are amazing as well...with jazz and well recorded material...I placed them no diffraction (straight at me) after a day moving them around the room....friend came over to have a listen and said "im tripping"...as his system is thousands! of dollars over my system...well matched and well placed in your listening room...if you like the 11’s...19’s are guaranteed to please you...
Sweetwater does carry the active/scm 20 for 5k...fwiw
