I suspect it depends mainly on how relevant engineering quality is to the business. Neumann are from the high quality end of the spectrum and an indication of their approach is given in the "Preaching Tolerance" section near the bottom of the page here. It probably represents around the best that can be achieved today for a modest cost. Of course it requires the use of active crossovers rather than passive but if technical quality is a requirement then that would tend to follow.I often wonder why manufacturers don’t break in their woofers before they reach the production line, especially on upper market speakers.
What would it cost them? Not a lot, given the prices they charge.
I find it unacceptable that the final customer has to do it. This often leads to disappointment after purchase.
Do speakers break in (or loosen up) if you just play at low volume, say 70db tops?
Last week I bought a pair of Linn Kan II (Ku stone) and straight out of the box they were very shouty with a fast low mid bass but no low bass at all.Yes, absolutely. Speakers definitely benefit from regular use IMO. Environmental factors are very real too, e.g. even a well used pair of speakers usually sound noticeably ‘off’ straight out of a cold box from a courier etc. A whole lot of factors at play, e.g. surround and spider compliance, capacitor forming, internal air-load in sealed boxes etc. I never like to judge anything until it’s been in use a good while.
This could be because of:
1. I am getting used to their sound
2. the speakers are breaking in
When the speakers are brand new, this sound difference comes from the break in.Last week I bought a pair of Linn Kan II (Ku stone) and straight out of the box they were very shouty with a fast low mid bass but no low bass at all.
A week later they are not so shouty and seem to have developed a much better low bass which I am very impressed (taking in consideration the size of the units).
