What the Pro’s are Saying

Pro Sound News:

Pro Sound News:

“The LSR310S came in handy when listening to an ultra-low frequency sound source in a mix. The sub allowed me to accurately gauge where these extreme low-end elements sat in the mix. The sub would be crucial when paired with the smaller 305s.”



“JBL nailed yet another successful LSR package. This subwoofer has all you could possibly need for true and transparent observation of lower end frequencies.”
