I have a pair of JBL LSR 305's and have been using an off brand sub that finally gave up the ghost. I ordered the LSR10S sub thinking that since it's the same series in the JBL Lin that it would be a great fit for my studio. I was wrong, it is an AMAZING fit with my system. It fits seemlessly into my system and provides such a level of clarity into the lower frequencies, I was blown away. If you have JBL LSR 305 or 308 studio monitors, don't even think of another sub. This is a perfectly matched and balanced system.I couldn't be more Happy
