Default Advice from Hi-Fi bods needed.

...with relation to running in speakers.

I did this with my B&W home cinema setup - ie leaving the speakers on with a low volume for a few hours before realing cranking the volume up, but should anyone do this also with any speaker?

Reason I ask is I've just bought some Infinity 6x9's for the scoob and a set of Sennheiser HD280 Cans for moi. Should I give both of these a run in too? I think it would be advisable to run them in, but how long is long enough?

The reason speakers benefit from running in has nothing to do with protecting them from damage like you would a car engine. It has to do with loosening them up quickly so that they sound as good as they're designed to.

Normal running-in advice I've heard from numerous sources is to place them face to face, wire one of them out of phase so that its sound cancels out that from the other, then crank the music right up for a few hours! This enables them to run at a high level without deafening you or your neighbours.

I've never heard of headphones being run in. As for car speakers there's not a lot you can do other than enjoy the music.

Don't worry, just enjoy

I agree i have heard about wiring one speaker out of phase,,

however i was told to drop an old duvet over the spkrs as there is still a fair amount of audiable noise...

It would have to be a mono source though.

Yes, in order to get perfect noise cancellation it would have to be a mono source.

However, in reality, most of the music comes from the centre so that bit will cancel out.

FWIW I ran my Tannoys in for 50 hours (as per recommendation). But it wasn't until a year after I bought them that they started sounding decent and fully run-in.

quote from a HIFI bbs,do this and face the speakers 3" apart,and chuck a quilt over so you cant hear it

for the left speaker I wire the red cable to the +ve terminal, and the blue/black one to the -ve one; as per the manufacturer instructions.

However, for the right speaker, he recommends that I wire the red cable to the negative ´ve terminal (and the blue one to the +ve one).

why do you say that Imlach? this has been common practice for years,for most speakers that is and makes perfect sense,particularly if you have auditioned a well run in pair on demo

Speakers are mechanical devices, so benefit from running in
