Abstract: Trace impedances are specified and controlled on PCBs, as their nominal impedance value and variations are kev factors in establishing system I/O bus performance.
5dB (1W/1kHz/1m) for DX3 and 103dB for DX4 driver, bandwidth of 30Hz-22kHz +/- 3dB, and power handling of 2 - 100 Watts into 8 Ohms nominal impedance.
They feature wide frequency response of 75 Hz to 18 kHz, 16 watts contours pink noise or 32 watts of continuous program capacity, and a nominal impedance of 8 ohms.
3s, but also tested its mettle driving the huge Sound Labs Dynastats, which even though their minimum impedance dips down to 4-ohms, their nominal impedance is 8-ohms.
The twisted pairs have stable 100 Ohm nominal impedance and a low 13.
If we specify our nominal impedance with a loose tolerance (choosing 90-ohms nominal for a 100-ohms diffpair) manufactured at +/-10%, together they will result in a 90 ohms +/-10% (81 to 99 ohms) range, which is outside of our original specification (100+/-10% = 90 to 110 ohms).
The low-frequency section provides a sensitivity spec of 94dB (1W/1M) with a nominal impedance of 8 Ohms.
Their frequency response is rated at 68Hz-21kHz; nominal impedance is 6 ohms; sensitivity is 91dB (1 watt @ 1 meter); and have a recommended power envelope of 10-80 watts.
Other specifications include a gain of minimum 1 decibel isotropic (dBi), a nominal impedance of 50 ohms, an omni-directional radiation pattern in the horizontal plane, vertical polarization, and a power rating of 3 watts.
Nominal impedance is 8 ohms, with a recommendation that the speaker be powered by an amplifier that is rated from 10-150 watts.
7 mm diameter, with nominal impedance of 75 ohms, 0.
The frequency response is 66-20,000 Hz +/- 3dB with nominal impedance of 8 ohms, sensitivity of 89dB and crossover frequency of 6500Hz.
