My belated SL Phoenix is 80% done. I was going to drive them with LM3886 chip amps with high quality parts, but recently heard an SE 845 triode amp made with high quality parts. The latter was far more expensive, but sounded far more seductive, without being at all soft.
How well do you think a similar 20 watt SE 211 triode amp – maybe based on the Ongaku
- would drive the Phoenix midranges (99 dB above 250 Hz, decreasing to 92 dB at 100 Hz)?
Linkwitz says:
The Phoenix main panel should work really well with low power tube amplifiers, because of its high sensitivity over the midrange and the generally low power requirements on most program material for the tweeter. The drivers represent an easy, low reactance load to the amplifier output transformer due to the restricted frequency range used. The output impedance should be low (<0.4 ohm) to maintain tight control over the voice coil motion.
Anyone heard tubes driving dipole midranges?
Thanks
