We must first understand that when a speaker is purchased new and in the box without any previous operation, that the speaker will need to brake in before a decision can be made on its performance. For any speaker to break in properly you will need to feed it some food, and that FOOD would be (((WATTAGE))) ... You will never Brake in a High-End speaker with a low wattage power amplifier or receiver. If your speaker is a 16 2 4 6 Ohm you will need 100 to 300 watts of power to warm up the new components like the voice coil, to then move and loosen the glue around the spider and soften the surround. You will do this at a low to mid volume. You must notice that the surround on the woofer is in motion and extending away from the outside rim of the speaker a 1/4 inch continuously until you can hear a noticeable change in its sound signature. You cannot put a time limit on how long it should take for a speaker to brake in. Because it may not be complete if you stop the procedure using a time to complete the procedure. But even then, after hearing the change in sound you should continue to feed it until you can feel a smile start to be forming on your face and then stay in place for hours. Then and only then can you completely judge the speakers for its sound definition and sound quality. So, if speaker placement and room sound treatment acoustics are in place you should be hearing the speaker at its full potential. Not to say that it will ever sound like you was hopping it to sound in the end result. And that end result can and will always be subjective to everyone who listens to your speakers in your room and space.
GOOD DAY! and PEACE to ALL!!!
