association enceintes et ampli - risque ecart de puissance

Message » 15 Mai 2005 20:59

Bonsoir,

Je souhaite avoir qqs infos sur le couple enceinte / ampli a tubes.
Je possede des JM LAB COBALT 816 et je souhaite acheter un ampli a tubes KT88 (Cayin ou autre) soit une puissance de 2*25W. Selon un article trouve sur un forum (voir ci dessous) les amplis de petite puissance peuvent endommager les enceintes.

Que pensez vous de l association CAYIN AT88 et JM LAB COBALT 816 ? Y a t il un risque ?

Is this amplifier too big for that set of speakers?

There is no such thing as an amplifier that is too big. In fact the bigger the better for sound quality. Small amplifiers are more likely to damage speakers than large ones, because small amplifiers are more likely to clip than larger ones, at the same listening level. I have never heard of speakers being damaged by an overly large amplifier.
I have heard of 100 watt speakers being damaged by a 20 watt amplifier, however, in really abusive hands. This will happen because when an amplifier clips, it will generate much more energy at high frequencies than normal music would contain. This high energy at high frequencies may be less than the continuous power rating of the speaker, but higher than the actual energy rating of the tweeter. Tweeters tend to be very fragile components.
