Hahah wow, 12 bins ö! I'm planning my own LaScala DIY build, but I have not found a really detailed build plan, so if you can help me with that would be awesome! Also, is there maybe an 18" LaScala build? If not, what would the lowest crossover point that you can have with the K55M? I have sub that can go up to 300hz, but the crossover point is 400hz normally. Have not decided on buying the K-4M, but good to know about the LaScala bassbin/midrange ratio thanks!
