<\/a><\/p>\n <\/p>\n It\u2019s the new mid-woofer from SB Acoustics<\/a> more exclusive series \u201cSatori\u201d. Satori in Japanese is a Zen Buddhist term for enlightenment. The word literally means “awakening”, “comprehension” and understanding”. The Satori drivers are designed for subtlety and realism.<\/p>\n My driver samples are the MW16P-4, which is the 4ohm version of the mid-woofer. The MW16P-8, 8ohm specification can be found here: MW16P-8<\/a>. The driver has a very nice looks and build quality. The small but yet powerful neodymium magnet together with the shape of the chassis contributes to an optimal airflow behavior.<\/p>\n To sum-up the Satori mid-woofer features:<\/strong><\/p>\n <\/p>\n Preliminary T\/S parameters measurements:<\/strong><\/p>\n <\/p>\n With >90dB @ 2.83v\/1m, the 4ohm version is a fairly efficient mid-woofer. It\u2019s most likely to achieve a system sensitivity of about 86-87dB @ 2.83v\/1m, when the right amount of \u201cbaffle Step Compensation\u201d is applied. Nice consistency between the two driver unit samples. About 25% higher Mms compared to the official spec sheet for the 8ohm version.<\/p>\n <\/p>\n Preliminary Impedance measurements:<\/strong><\/p>\n (click on picture to zoom)<\/p>\n Left:<\/strong> Free-air impedance sample 1 vs. sample 2. A very sharp and narrow impedance peak at the resonance frequency of the driver unit, which indicates a mid-woofer with low mechanical losses. The edge resonance occurs somewhere between 1-1.2kHz and will most likely give a hole in the frequency response and some elevated 2nd order harmonics at the same frequencies. From the impedance measurements, cone break-ups are visible at about 4kHz and 6kHz. How severe these break-ups are to be determined in the frequency and distortion measurements.<\/p>\n This mid-woofer should be able to be used up to about 3kHz, but some frequency and distortion measurements analysis remains to be certain.<\/p>\n <\/p>\n<\/a><\/a><\/p>\n\n
