The Total Eclipses' sensitivity is a true 94 db @ 1 watt into 14 ohm, measured in room at a distance of 1M. The 86 db NRC measurement published by Soundstage was the result of 3 factors:
1. Measurement was taken in an anechoic chamber- 3db discrepancy compared to in room;
2. Measuring microphone was placed at the non standard 2m distance, not 1m - 3 db discrepancy
3. Measurement was into 8 ohms instead of 14, accounting for another discrepancy of 2.8 db.
Therefore, the NRC measurement of 86 db combined with the discrepancy of the above listed 8.8 db, and the genuine sensitivity of the Total Eclipse is an authentic 94 db.
The Total Eclipse can easily be driven to high spls with SET amplifiers of 8 watts. Whether that is satisfying to every listener is another matter. Higher power amplifiers have their own advantages regardless of speaker sensitivity. Our website discusses the amplifier power issue in more detail.
