Hi ?? First of all, I want to thank woodbrass because they are very professional... good team to advise you... Very fast delivery ?? and that is nice... As for the subwoofer, well I was blown away by the power it develops... It's still impressive, good bass that hits well even at low volume... It is so powerful that I don't even set the volume to half... The bass is really of very good quality... I have tried several subwoofers and really the alto is superb... And it must be said the subwoofer has very nice finishes, you can feel the quality is there ?? To conclude, I would say it is a very good subwoofer... If you don't have a big budget but want a powerful and good quality subwoofer, well this subwoofer is made for you... You will not be disappointed... I specify that I am posting this comment fresh, it's been 7 hours since I received the subwoofer so I can't say much yet but it suits me, now to see in the long term... Have a good day ??
