Hejsa

Jeg kunne godt tænke mig at høre jeres mening om følgende :

Hvilken højttaler lyder bedst kef 104.2 eller 105.2 ?

Højttalerne skal drives af et par Denon POA 6600A monoblokke !

M.v.h.

 Jeg har haft 104/2 , det er en letdrevet ht. som er  ohm´sk liniær i 4 ohm det kræver en god effekt.
 Jeg har drevet dem med en Denon  POA 1500 uden problemer, så 6600Abør ikke have problemer.
 Køber du et sæt 104/2 så se efter ophængene på basenhederne de er lavet af skum og vil trænge til renovering inden længe. de nederste basser er særligt udsat , hvorfor ved jeg ikke.
Jeg har set enkelte modeller med B 200 basser med gummiophæng, tror dog ikke det er originalt ?

 
 

Model 104/2

Model 104/2 is a classic high output, high sensitivity loudspeaker system with exceptional dynamic capability. Since its launch, this elegant Reference Series loudspeaker has won awards worldwide for technical innovation and acoustic performance - and no wonder. Model 104/2 incorporates KEF Reference Series dual coupled cavity bass loading, an innovative arrangement which improves low frequency performance and reduces distortion while delivering tremendous bass output. Twin chassis-less midrange units effectively eliminate chassis resonance. The very embodiment of all that makes Reference Series so special, Model 104/2 has a performance level way above its size.
