[QUOTE="TeoTorriatte, post: 4517212, member: 571999"] The ONLY thing break in does is stretches out the suspension -- something that doesn't really [I]need[/I] to be done, but is often done in DIY audio circles to provide for more accurate T/S parameter measurements. If you want to break the suspension in for measurement purposes (or just because you want to loosen up the suspension for whatever reason), I'd suggest the following... Since you don't need more than one frequency to accomplish this task, pink noise or music are really not necessary. A sine wave just below the Fs of the driver being broken in is all that is needed -- played at a volume level sufficient to generate a good amount of excursion (to stretch the suspension). The amount of time that it takes to fully loosen the suspension varies from driver to driver -- I've had drivers see very little benefit from break-in, and I've see drivers that experience a 2-3 Hz drop in Fs after an overnight sine wave session. If you don't care about loosening up the suspension beforehand, then just make sure you have everything wired up correctly (VC's in phase) and let them wang. They will break in naturally over time...
