So I just couldnt resist driving up to seattle and buying those L-350's some of you saw on ebay. So how do they sound? Well amazing, I'm enjoyin the sound they produce a little more than my L300's. Advantages seem to be the tweeter and horn are more at ear level which really really helps by the way. Bottom end seems really smooth and tight I will be testing them a little more just got them home Cabinets are beautifully made, they did an excellent job even with the grills which are 3d like the L300 grills. They do weigh more than 100 lbs, i'd say 150 lbs or so each.
