Grundig HiFi 4000 (1960s)

Documentation on the Grundig HiFi 4000 is thin. Here is what the record shows. It was a complete hi-fi system (“Hi-Fi-Komplettanlage”) from Grundig’s 4000 series, a line that also included the separate V-4000 amplifier and the T 4000 cabinet speaker. The system appears to have been a console-style unit. The amplifier section measured roughly 52 cm wide, and the whole setup drew about 300 watts. The tape deck used two motors, three capstan gearboxes and four tracks, and ran at 4.75, 9.5, and 19 cm/s. Total harmonic distortion was rated at under 1% at rated power.

One caution. The surviving spec sheet for the HiFi 4000 is a series-level page, so some of those figures may belong to other 4000-series components and not the console itself. The V-4000 amplifier is much better documented. It was the smallest integrated amp in the series, produced from 1967 to 1969 at a list price of 428 DM. It delivered 2 × 14 watts sine into 4 ohms, with a frequency response of 20-20,000 Hz ±1.5 dB. The T 4000, introduced in 1965, was the entry-level furniture speaker. It combined the amplifier-tuner unit and both speakers in one cabinet, with output stages rated at 2 × 40 watts music power. Studio Sound (April 1967, p.43) reviewed the related TK 340 recorder in that era, which shows the component-level testing Grundig gear got. No period review of the HiFi 4000 console itself has surfaced.

Beyond its listing in period directories, almost nothing else is recorded about the HiFi 4000 specifically. No exclusive production years, no standalone price, no tuner specifications and no collectibility data have been found.
