Included in your kit is a large chart that tells more stuff than you can shake a stick at. Look up what the limit is for front weights given the data you have supplied. This will keep inertia in the "normal" range. I did forget that up and down has to be measured without springs. Only one lead leaves ample room to install additional lead. You do not want more than four in the low bass and three in the middle range to next to nothing in the very top. This would be "normal". Lots of other good advice provided by others. Have fun. Newton
