From Sound & Recording.
Those are/were quite popular with audio professionals - even hyped. Can't quite see why.
Price is 2700€ for the speakers and 1560€ for the amp. A pair of Neumann KH310A costs about 750€ less and is much more accurate. Similarly, a pair of Genelec 8350 with GLM kit costs about 300€ less and is also more accurate. For 400€ more, one could even get Genelec 8331 with GLM kit which are more accurate and have exceptional dispersion.
Power at 2x4Ohm. Striped: 100 Hz. Straight: 1 kHz. Dotted: 6.3 kHz. Measured with APx555 and AES17- and AUX-0025-low-pass-filters.
SINAD at 5W is between 90 dB and 94 dB and clipping point seems to be around 250 W at SINAD of 60 dB. Residual noise seems to be around 27 µV giving a 5 W SNR of 104 dB and SNR at 1% THD+N (320 W) of 122 dB. While noise is fairly low, this is still far from impressive for 1560€ and the March Audio P502 delivers similar performance at about 60% less price ($1075 is 966€).
Frequency range: 56 Hz – 19,3 kHz (–6 dB)
Deviation: ±3 dB (100 Hz — 10 kHz)
horizontal opening angle: 120 degrees (–6 dB Iso 1 kHz — 10 kHz)
horizontal standard deviation: 18,3 degrees (–6 dB Iso 1 kHz — 10 kHz)
vertical opening angle: 127 degrees (–6 dB Iso 1 kHz — 10 kHz)
vertical standard deviation: 20 degrees (–6 dB Iso 1 kHz — 10 kHz)
max. usable SPL: 101 dB (3% THD 100 Hz — 10 kHz)
Bass ability: 94,3 dB (10% THD 50 — 100 Hz)
Max level at 1 m (free field) with EIA-426B Signal at full scale: 94 dBA Leq and 109 dB Peak
Paar deviation: 1,7 dB (Max value 100 Hz — 10 kHz)
Noise level (A-weighted.): 3 dB SPL with Amp500 at 10 cm distance.
Dimensions / Mass: 191 x 380 x 305 mm (W x H x D) / 12 kg
