| Power Rating |
200 W Continuous Program (2 hrs) *Continuous Pink Noise rating is IEC-shaped pink noise with a 6 dB crest factor. Continuous Program Power is defined as 3 dB above the Continuou Pink Noise Rating and is a conservative expression of the system’s ability to handle normal speech and music program material. |
| Maximum Input Voltage |
25.3 V RMS (2 hrs), 50.6 V peak |
| Maximum SPL (1m) |
110 dB ave. Continuous Pink Noise (116 dB peak) *Calculated from sensitivity and power handling, exclusive of power compression. |
| Sensitivity |
90 dB, 1W/1m (ave. 100 Hz – 10 kHz) *Half-space (on-wall) averaged 100 Hz – 10 kHz, 2.83V. |
| Coverage Angle |
100° x 100° *Coverage angle (-6 dB) average between 1 kHz and 12 kHz. |
| Directivity Factor (Q) |
6.04 (averaged 1kHz – 16kHz) |
| Directivity Index (DI) |
7.6dB (averaged 1kHz – 16kHz) |
| Impedance |
8 ohms |
| Crossover Type |
2nd order low-pass, 3rd order high-pass |
| Recommended Protective High-Pass |
60 Hz high-pass (24 dB/oct) *For protection against driving below resonant frequency and to keep transformer out of saturation. |
