Oh and a little birdy whispered in my ear that reed cage spacers (favor bottom/midrange) will not fit on VF3's because they are shaped a little differently then a stock cage. Is there any truth to do this? Has anyone tried to run a spacer with them or does anybody have one installed with a set of the 3's? I put my new spacer on my stock cage today and noticed a decent boost to the bottom. And I don't think I lost any top end (if I did it was very little to where I didn't notice it)
