Upgrading My KEF Q350 Speakers - Resolving Cabinet Resonances and Upgrading Crossover Parts

In this video I upgrade my KEF Q350 speakers with the hopes of making them sound better. If you saw my look inside video on this speaker, then you know the damping inside the cabinet, and quality of some of the crossover parts leaves a lot to be desired. In this video I measure the cabinet for resonances and work on resolving them. Next I turn my attention to the crossover to see if upgrading some of the parts will make an improvement in sound. Join me as I take one of my favorite bookshelf speakers to the next level.
