stesse domande per queste casse

faccio queste domande perchè devo comprare un paio di casse attive e sto facendo una ricerca approfondita prima di comprarle

Chiedi anche per queste casse le stesse domande,chi mi sa rispondere(magari le ha già viste o sa già come sono strutturate)
l'importante è che siano attive e che abbiano l'entrata per il cavo maschio audio stereo jack 6.3mm trs balanced(tip ring slave)(jack stereo) e poi sapere anche i watt rms
