Also, what's up with Canton's specs, with regard to bass frequency response? I see that they claim 20Hz for the 890.2. Given the cabinet size, how can they do that? What do you think is the real world bass extension?\n\nAnd what is the difference between the Vento 890DC and the 890.2? Which is the newer model, and which is considered better?\n\n\nI'm afraid I don't know much about Canton's frequency response specifications. Some companies (Klipsch & Paradigm, to name a couple) refer to a "typical in room" response that takes advantage of the room gain often seen in lower frequencies. Other companies use a -6dB or even -10dB rating for the FR.\nLooking for a comparable speaker (dual 8" drivers),the SVS Ultra Tower gets 28Hz at -3dB.\nhttps:\/\/www.svsound.com\/products\/ultra-tower\nSo, I agree that the 20Hz is not likely a straight-forward -3dB spec.\n\nThe 890.2 is the more recent speaker and from the same series (and thus same or equivalent design of drivers) as my 820.2.\nI have spent a while trying to establish the differences between these speakers and do not feel confident of anything. They have too many different speakers and do not provide this information. If you call A4L and ask for this information, they will likely refer you to their buyer for Canton speakers who has a pretty good handle on the models that A4L carries.
