Very nice small mid-bass

Reviewed by Tom_S on 05/08/2021

You gotta love it when you find something that performs way beyond your expectations. These SB mid-bass drivers do just that. I was quite surprised at the solid low end these can produce in 14 liters or a little less. The mids are great too. I've heard the ceramic version and it's an equally impressive driver that delivers on the slight uptick in price.
