Great sound and great price

Ryan Forsythe
Awesome Land Cruiser Stereo!

I use my Demer Box as the stereo in my vintage Land Cruiser because I didn’t want to cut a hole in my clean dash. Great sound even with the top down and the tan color is a great match with the Cruiser’s paint! Thanks Demer Box, very pleased with my purchase!

Michael McCarthy
Best most durable portable Bluetooth speaker available!

What can I say. The DemerBox is the best portable speaker on the market. I now own five. Always reliable. If something does need to be repaired the company’s customer service is excellent. I haven’t needed a repair but I did upgrade my original speaker to the newer improved version. Great product. Great company.
