New speaker "break-in" music?

Almost any kind of fairly full-range music played at moderate volume will work fine. The objective is to "exercise" each of the drivers in the speaker, so music like orchestral, big band, etc., works fine.

crystal method,,,,,

Just play the stuff you love!
Listen to them go through the process. Sure you could put a cdp on repeat playing some burn in track from a Stereophile or Chesky evaluation compilation.You could play "Pink Floyd","Pink",pink noise,pipe organ classics,or "Cosmic Hippo",but really just play what you love.
200 hours is about 8 days straight.Out of a 24 hour day average person has maybe 4hrs max to expend for fun. Time has no refund.
You still here!Goooo!Play those new speakers!#:^)

Hi Uncontop. Great choice of speakers sir, you will love them. Nice right out of the box, but they will need all of 200 hours of run in time to come into their own. Enjoy!

Electronica.

XXX (Triple X)soundtrack.

Whenever I get a new set of speakers I run the first disk of the XXX (Triple X) movie soundtrack -- Vin Diesle -- on repeat for as long and loud as I can. Alot of electronic insruments, very deep bass and intense drumming and cymbals throughout. Kicks the heck out of whatever speaker I am breaking in and works fast.

Yes thats an excellent way to flesh it out.

Eddaytona,

The guy just wants to break in his speakers nothing more :)
