Thanks for posting the preview and capturing the notes in their reveal. Will Audioholics do a real review done on these speakers with measurements?
I hope so. Those speakers have quite a few features in common with my left and right mains. I suspect that the BSC duty is offloaded to the upper woofer, like mine.
In addition the lower woofer just handles the lowest frequencies. However, my researches showed that trying to do this with passive crossovers is not at all ideal.
This does really require an active solution to implement well. In addition the lower F3 point is 24 Hz. So essentially that speaker is a full range speaker, and probably at that price the cheapest one on the market.
However an active or hybrid active/passive would have allowed the LFE signal to be mixed in to the three woofers. That would have dispensed with the need for subs, I'm pretty certain. In addition an active solution allows for variable BSC to allow the speaker to be voiced to the room and its position in the room.
I have no need of separate subs, and I can attest to the high value of some of the concepts this speaker employs.
My design from 2005, has stood the test of time very well, and with the extremely natural bass of the TL design has been an outstanding success.
If there is one thing I have learned through all this, is that there could be a lot more speakers on the market than current choices. Designers have not been nearly as imaginative as they should have been.
