<font color='#000000'>The brand of the speakers is revox, but the woofer has a sticker of the brand Studer they are kind of old so i dont think they can be replaced i will look for new ones, different ones. Ive looked in ebay and i have seen some that i like but i dont know if they are in a good state or damaged or what so i searched in places like woofers.com and madisound.com</font>
