I was in the middle of A Bing some ground enhancer tweaks, which attach to the negative binding post of the speaker, on my Selah Audio Excelarrarys, when I discovered that the whole post was turning, when I tried to tighten it down. This of course means that the nut on the back side of the binding post was lose, which also means the connectors attaching the wires from the crossover were not making a solid connection. So I pulled the binding post cup off both speakers, and made sure all the nuts on the back side were tightened down, they must have loosened up over time. Well I was shocked when I sat down and listened again! Transparency, focus, bass articulation, all took a giant leap forward. I guess it shouldn't come as a surprise, that lose connections may have detrimental affect on the sound, but I was shocked never the less. I also remember thinking for a while now, that things were not quite up to speed, with the sound of my system, well as it turns out, that was only part of the problem. I also happened to notice, upon closer inspection of my speakers, that some of the screws holding the Seas drivers had backed out, again, this must have happened over time. So I went through all 12 drivers, and checked and tightened all the lose screws. Once again I was shocked at the difference I was hearing! This was another huge leap forward in transparency, focus, and bass articulation. You know us audiophiles are like junkies, who often get restless, and tried of our gear over time, and start looking for the next "fix". That's kind of where I was at, and why I was trying Ric Schultz's ground enhancer tweak, which is a topic for another discussion, elsewhere. So leaving the ground enhancer tweak out of the equation, and just focusing on the two speaker maintenance tips, my speakers have been restored to their former glory, and my supposed need for another "fix", has been quenched.
Just thought I'd pass this along, as others may very well be in the same boat. Thinking that they need to upgrade their speakers, or make some change to their system, when all that may be needed, is a little maintenance.
