I'm not aware of any speakers that are constructed like that anymore. I bought the last of that breed, the ACI Talisman SE, a couple years ago. ACI was ceasing production as production costs were rising and they weren't sure about marketing it at a higher price point. I'm blessed with a good room that supports bass well and the Talismans have proven to be an excellent speaker. Their design places the woofer sections at the side of the cabinets like some Coincident and Audio Physics designs. Front firing drivers are symmetrical, so they can be placed woofers firing in or out depending on the room. After having the ability to tune each speakers bass output to taste and experienced the benefits, i'm relectant to go back to traditional all passive designs. You are correct that this approach allows for development of easy to drive speakers. No doubt Shadorne is right as well. Perhaps one thing that holds many back from acceptance of having completely self powered speakers is that many of us like to be able to try different amps and enjoy experimenting. When you buy self powered speakers, it's too simple, nothing to confound us!
Top notch speakers with their own sub
I have a pair of Infinity Prelude MTS complete with subs and towers. They serve me very well, don't require too much power because they have their own powered subs. The multiple components for upper base and mid range do have their advantage, giving a rather complete sound projection. This pair of Class A speakers certain have lived up to their pedigree, but the technology is about 10 years old. What would recommend for the current technology? I am looking for a pair of full size speakers that have their own powered sub.
