Frankpiet-Are you judging bass extension based on manufacture specs and propagandas? If so, you should buy the YGs. They are the best speakers on earth you know. Anyway, back to reality, the Avalon Indra, based on JA measurements were app 15 db down at 27Hz. The V3 on the other hand, are only 6 db down at that point. If you are hearing more weight out of the Avalon, I suggest some serious soul searching , weight and dynamics are not the Avalon cup of tea
BTW, I heard the V3 on the Boulder at the CES last year. Best sound at the show, hands down. I was not the only one who felt that way (See CES 2008 press coverage).
