### ⭐⭐⭐⭐⭐ Review
*by C***N on 3 February 2025*

Nonostante sia minuscolo, esprime una potenza impressionante! Con un normalissimo alimentatore da notebook 19,5V 3,5A mette a dura prova il mio sub da 160Wrms 4ohm.. volume mai oltre la metà, diventa appena tiepido.. incredibile! La frequenza di taglio, a orecchio, mi sembra molto inferiore ai 200hz, direi 120÷150 max. Il che non è male per un subwoofer da 8" abbinato a satelliti medio-piccoli. Probabilmente per pilotare un 12" servirebbe più bassa.
