Ma la potenza?
Una domanda ma come si calcola la potenza che dovra avere l'ampli rispetto alle casse?
Per me 70w per due casse da 200w sembrano pochini, mi sbaglio?
Il mio obiettivo è avere a disposizione potenza, definizione e bottan sui bassi.
Per questo ho scelto le B&W che hanno un range di frequenza molto esteso, e che inoltre avendole sentite ne sono rimasto folgorato.
Mentre per l'ampli sono molto indeciso, perchè voglio potenza e versatilità.
Ho trovato usato un Rotel RA-1070 a 700 euro...
