These ones are huge size, about the size of a tablet but once fitted they are very handy to carry and comfortable. I had these to replace old ones I had in the top speakers (they broke) and these ones did the job very nicely. I would not hesitate to recommend thse. Just make sure the whole fittings are similar / the same and that it does not disturb anything inside the speakers. I had to redirect the cabling inside mine to avoid problems but can easily be done with hot glue and the proper cabling. One thing I would like to see in these is that maybe they should come with appropriate screws... but for this price you cant get any better.
