Technics - SB-4000 Speaker set

Technics SB 4000

The Technics SB/4000, a speaker from 1978, is known for its "linear phase" design, which provides accurate timing of the sound and a realistic stereo image. It is a robustly built bookshelf or stand/mount system that delivers surprisingly clear and warm sound for its age. With a power handling of 50W to 75W RMS and an impedance of 6 or 8 ohms, these speakers are relatively easy to drive with a variety of vintage amplifiers. For vinyl enthusiasts, it’s a solid choice that is often found secondhand at an attractive price, although you sometimes have to check the specific connections.

Specifications:
Frequency Response: 40 Hz to 20 kHz.
Power Handling: 50W / 70W RMS.
Input Power (max): 75 watts.
Nominal Impedance: 6 Ohm (some sources list 8 Ohm).
