I've owned all 3 , Morrow is all about Air and detail, SC5-E
is solid from top to bottom but less "airy' .
Clear Day Shotgun is not a choice for speakers as inefficent as yours, need Double for that.
If you listen to mostly acoustic music, I'd get the Morrows.
For Rock I'd get the SC-_5
But any reasonable person should be happy with either.
