This is one of the most musical subwoofers I have listened to, and the transients responses are one of the best as well. You are right in saying that this is not the kind of subwoofer that is designed to do 10Hz in a HT setup though. This should be regarded primarily as a 2 channel music setup.
And if you can't afford two Toruses--as I certainly couldn't--the Minis will do just fine all by themselves, though, once more and for the last time, they won't go down below 20Hz with the flat response they have above 40Hz and they won't play in the 20-40Hz range with all of the authority you hear on real instruments capable of playing notes this low. Something has to give with a two-way; that's just fact and physics. If you listen, primarily, to power music, you may be left a bit wanting. But only a bit, depending on amplification. (I am told, by Alon Wolf no less, that the $40k ARC 610T makes the Minis sound as if they have a subwoofer.)
exactly what is power music? if the Mini's claim to fame is chamber music and symphony, do note that organ and lower piano are around 16 Hz and 27 Hz, respectively...and the Mini's dive where...around 40 Hz...i don't mean to be sarcastic but
it is my contention that a bookshelf speaker of the caliber and price of the Minis should be able to do all things well...and all the boasting about the board flat frequency response...what happens when you put it in a room that is'nt acoustically treated up to the wazoo? That flat FR won't matter so much then...the number and severity of resonances in the room will dictate the sound signature to a large degree...I'm not saying that the Minis are'nt technologically cutting edge, i'm just saying that "some" loudspeaker designers would have you believe that the only thing that matters is the speaker itself...that's just not factual...
on AVguide, for the Torus, i don't see anything of mention as far as GP measurements THD tests, impulse response, power compression, etc. etc...just subjective opinion which "usually" comes off with a certain degree of bias...the Torus is an achievement, no doubt, but transient response is only one facet of VLF production...as a matter of fact, as you pull the crossover frequency lower, you increase the time delay between the region below it and the region above...phase shifting becomes more pronounced as frequency falls...of course, the severity of this shift will be dependant on the Q and cutoff rate of the filter.
