Thanks, much as I thought. I guess there must be some cost/befit thing going on . Weight (for me ) is important, so if a field coil speaker was much lighter than a perm. mag. I`d go for it. Though I think someone will soon make a good guitar speaker using one of the new `rare earth ` magnets (I can`t spell neodidium) and the weight problem will be over, PT
