Hi,

I just decided to upgrade my Marshall 5 combo speaker.  When installing it, I noticed that there is a rubber stopper on the bottom of the amp, facing the speaker.  I'm assuming this is to guard the speaker magnet from damaging the amp(?).  However the replacement speaker's magnet is larger than the stock.  Can I remove the rubber stopper?  Is there another purpose for it?  Any potential damage to the amp or transformer by removing it?
