I tried a Line Magnetic with an older Gallo speaker 4 ohm 90 dB sensitivity. It did not work well at all. I concur with the other posts. It’s the impedance not the sensitivity that matters. Line Magnetic does not like low impedance speakers, but check with the distributor, Tone Imports.
Minimum recommended amplification requirements and amplifier matching
If a speaker has a "recommended amplification requirement" between 80W-200W with a 90dB sensitivity what are the actual minimum amplification requirement? In particular, the Line Magnetic 211ia is rated at 15W triode and 32W ultralinear. Can smaller tube amplifiers provide enough wattage to drive speakers that require more than twice the recommended output?
