Nah man, the sound was pretty hollow. Do u have many boomboxes ? Maybe you came across this "type of box before, this one is just a big empty box with some chrome on the outside. It's what the mid-late 80s boxes deteriorated into as people just wanted bigger flashier boxes but they didn't want to to pay for quality. maybe you could upgrade the speakers but it's such an unknown brand I'm not sure there would be any help/parts available. You'd be better off getting another one. one of the exceptions in the category is the Lasonic 931/975 which looks flashy but also sounds dope.
Yeah, I know that boomboxes in general downgraded towards the end of the 80s. Didn't think the Panamax would be that bad though.
I actually got a TRC-975 and was worried it would just be another hollow box but I've only heard good things about it.
