I have had some Polk Monitor 10s that I have had for a few years and love the sound of them. I had to realign the magnets on some and JB Weld all the mid/bass drivers so I thought the SDA's (being the holy grail), would be something I should pursue. I found a pair of CRS+ in good shape on CL while I was on vacation and bought them. I heard them and was not blown away but thought "they'll sound better with my setup". I got them home and I'm a bit disappointed. I have some old Small Advents and a pair of DCM TF400s that have a more pleasing balance to my ear. I'm not hearing the SDA "magic" I was hoping for. What would be the first step to bringing out that "magic". Replacing the tweeters, redoing the crossovers or what?
