Again George I don’t believe that anyone reading this thread will find it misleading or confusing. People can appreciate real listening encounters versus supposition.Supposition? the proof has been given by two reviews and two bench tests with graphs.
These speakers load is way too hard for an 8w SET or low powered tube to drive from the bass 80hz up. who partners a 1200w lower bass amp with a 8w set bass/upper bass amp!!!
And Keith Howard would not have stated this if it wasn’t just a supposition!!
HiFi Review LAB Test: by KEITH HOWARDTo anyone thinking of buying theses speakers do your homework when buying an amp, or you’ll be a fool soon parted of his money if you believe these speakers can be driven to their best by low powered tube "flee" amps.
We measured a minimum modulus of 2.9ohm and a minimum EPDR of 1.3ohm at 92Hz, with further dips to 1.6ohm at 219Hz and 2.0ohm at 584Hz.
So the One.R is a tough loudspeaker to drive, despite its powered bass section.
Only this type of 25w "flee amp" will drive them, ones that can double their wattage all the way down to 2ohm. 25watt only into 8ohms, ML2 monoblocks from Mark Levinson
