Home High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

RE: Making the move to high efficiency seems impossible...




You don't necessarily need a more sensitive speaker, you probably do need one that is easier to drive than the Ariel, or else amps that can drive the Ariel's with more ease, or both.

See the attached electrical load and phase diagram courtesy of JA. He calls these speakers a "moderately demanding load". The min. impedance is 3 ohms and the speaker is mildly reactive from 300 hZ-up.

If you can find a tube-friendly speaker with a relatively flat impedance curve that averages about 8 ohms over the frequency range; has no big negative phase angles, and is between 85-90dB, you'd probably be fine. That opens a very large range of speakers to you.

I'm just not sure about how your amps match this speaker. I'm not a biamper, but I would think that 175W from just one of your amps into those 4 ohms dips should work fine. Before, I got new speakers, I'd try pouring a little more power into those speakers. What about an SS amp?
