Hello to all,Hopefully someone with knowledge can help with this. I read somewhere that in the 60's the D130 and 130A use the same baskets, same cone and are more like 8 Ohms, with the only differences being a voice coil on the 130A made of copper and D130 of aluminum, and the dome on the D130 aluminum. Here is the question if baskets and cones are the same shouldn't the bass be the same only the D130 reproduces high frequency because of the aluminum dome close to the coil. I will be using a D130 in perfect shape because I can’t find a 130A in the same shape. I wonder if the D130 will do a nice Job getting to 1.2 K and let the 175 do the rest. This will be my vintage system using a 001 system with a Mcintosh MX110Z and a pair of MC30 amps.Thanks,Angel
