Ciao smanettoni,qualcuno e' in grado di calcolarmi un box per un subwoofer con altoparlante L15P200AK...RCF...4ohm?
Magari sugli 80 litri? O 100 sarebbe meglio? Cioe sipende se ne vale la pena farlo cosi grande,se cambia di poco..preferirei piu piccolo.
Il sub lo collochero dentro all'ambiente di un camper...per cui nn in un baule.
Non ascolto hip hop e rock,ascolto elettronica..ma anche ricca di basse frequenze..certo nn bassoni da hiphop!
Vorrei tirarci fuori tanta pressione ma anche una discreta discesa! non faccio spl!!!
Penso che prediliga il reflex... ma in chiusa come si comporterebbe e in ke litraggi?
Grazie per l'aiuto che potete darmi
