This is a question that Mr Widget can best answer I think, but others are welcomed.
In many of the former threads there have been discussed dimensions of baskets, cones, what re cone kit is going to work in what speaker etc...
In many of these threads it says that the 2220/130 is completely different from other speakers like the 136, 2205, k130, 2235 etc...
What is the actual mechanical difference between the two
bass driver baskets 2220 and 2235 (measured in mm). I know the topplate for the 2220H is 9 mm thick/deep, but what is the measured dimension of the
topplate for the 2235 ? Between the two loudspeaker models, Is there a mechanical differance in the frames too (hights) ?
It would be interesting to get to know how many speakers and what models you (Mr Widget) might have on your mechanical dimension list ?
