What is the difference between these two?  I bought a very nice pair of AV1+ for a song a few weeks ago.  I wanted to hear a bit of the GR sound.  I like them very much.  Do these use the same drivers?  Crossovers?

The speakers are basically the same. The name was changed to keep it simple.

The older A/V-1+ model used a GR-T1 tweeter. The tweeters have been changed twice since then going to a GR-T2 and now a GR-T3. The crossovers were also adjusted a little each time the tweeter upgrade was implemented.

Cool thanks.  Would it be difficult to upgrade the tweeter/crossover?
