Do you mean speaker size? 1 (I suppose that's the actual ir speaker size, isn't it?)
I think its the measured distance of where the the mic is placed i.e.. It could be 1inch or 3 inches or more etc from the cap of the speaker . The closer to the cap the brighter and darker towards the edge of the cone etc . In this case you have a lot of irs to choose from . If you click on the ir file it might read SM57 CapEdge-3inch.syx. for example . Ive had the RW Blues and Silvers for a while but haven't got round to trying them all .
