Break-in of speakers and other electrical components is a fairly common practice, and is widely recommended throughout the industry. It is not necessarily a requirement to use our recommended break-in procedure in order to get excellent performance from a REL subwoofer, however, we find that this procedure works well and offers the most consistent results for loosening up the components of the subwoofer’s drivers (for example the rubber surround which is stiff out of the box but loosens up to allow for longer driver stroke) and for warming up the electrical components in a controlled manner. As long as you do not immediately play a new subwoofer at loud levels first thing after taking it out of the box, since the physical moving parts of drivers require time to loosen up, there is no way to get it wrong per se. We have just found that our recommended process is easy to follow and yields consistently positive results.Are you with REL? Would you care to comment on why RELs ship with 6 dB potential that has to be realised through a very complicated break-in process? Surely there is a huge risk that only a fraction of your customers get it wrong and are stuck with a sub that only plays half as loudly as it could. Why did you choose this approach?
