I'm very interested in upgrading my LRS using the GR Research kit but I've got a few questions I'm hoping a member can answer that has gone through the process. Specifically, how difficult was the kit to assemble. I'm proficient at electronics / wiring but I haven't seen much about the level of documentation provided with these kits. Has anyone mounted this crossover externally, if so, any tips? Secondly, how different was the sound? Still Maggie-like with a big increase in transparency? Danny mentions how hard the tweeter is being pushed and at higher volumes I hear this -- does this completely clear that up? Thanks!
