Hi Palomino, Thanks, yet again, for your help! My listening room is about 13'x17'. I listen to a wide range of music; pretty much anything from classical to jazz to classic rock. Most of my listening is near-field, sitting about 8-9' from the speakers, but my wife and I like to have music playing while we work at home or are in the kitchen a couple of rooms away. I currently have a Michael Yee PA-1 power amp (100W/channel into 8ohms), and have the volume pot on my line amp (also a Michael Yee) at about "8-9 o'clock" for listening, and the volume is plenty loud. I was planning on trying to use the Torii Mk III alone, without the line amp, for the purest signal. The specs on my specific speakers appear below. Thanks so much!
Eos HD Performance details:
Application(s). Time-coherent 2-way speaker sounds best on stands or a bookshelf.
User adjustability (Soundfield Convergence™). Tweeter adjusts front-to-rear in its channel via easy-to-use thumb-nut.
Power (amplifier’s 8 ohm rating). 7 to 150 Watts.
Response. In-room, typically +/- 2dB from 50Hz to 20kHz; - 3dB frequencies below 47Hz and above 26kHz. 20 to 24-inch high speaker stands recommended.
Distortion. <0.5% harmonic 100Hz-12kHz, <1% intermodulation, both at 98dB at 1m (I.M.D. is for any two frequencies separated by a 10:1 ratio.)
Phase shift. +/- 2 degrees acoustically, from 200Hz to 8.5kHz for Eos HD. Does not vary with loudness.
Rise time. <10 microseconds, positive or negative input. Does not vary with loudness.
Polarity. Positive, over full bandwidth.
Dispersion. Omni at 47Hz, smoothly decreasing to cardioid at 12kHz.
Impedance. 4.8 Ohms, +/- 0.75 Ohms 100Hz to 20kHz. Does not vary with loudness.
Sensitivity. 90dB for 2.83V at 1m, at sea level. Dynamically linear within 0.5dB to 100dB.
Max SPL. 105dB peak at 3m from stereo pair, first-arrival (without room gain).
Pair matching. Amplitude +/- 0.25dB; impedance +/- 0.15 Ohms, 160Hz-8kHz; crossover parts +/- .15%.
