I have reviewed your advise to me last december about mt set-up, you said that it is better to go with the 2206 12" for Midbass and midrange rather than the 2020 for my setup. My only concern with the 2206 is that it is only 95db sensitivity as compared to 105db for the 2020H. I am afraid that a 22-watt SET amp might not be able to drive these 12"ers to the same level as the rest of the system. Any comments about this?Last time, I planned to get the 2242H 18", but when I load this driver at Boxplot software and WINISD, it doesn't have an f3 of 25hz or 30hz, something like 42hz, while the 2241H has a f3 of 35hz which means it can go a little lower than the 2242H. Is this true?
