Have been searching around but can't seem to find the specs on the speakers in my 2018 Evora 400 that has the Premium Audio plus Subwoofer options. I'm fairly happy with the head unit but the word on the street (this forum) is that the speakers could use an upgrade. I don't know if the Premium package employs better drivers than the stock ones. I would think the head unit upgrade alone wouldn't justify the extra $1,400. I hear the added sub isn't worth the $500 either. Would like to shop out replacements before tearing things apart. Model #s on the speakers would be very helpful, thanks.
