Akai Cs-f21 -
The Akai CS-F21, produced around 1982–1983, is a 2-head stereo cassette deck featuring Dolby B/C noise reduction, full logic transport control, and support for metal tapes. Known for a frequency response of up to 18,000 Hz on metal tape, it features a single DC motor and peak-reading meters, with serviced units often found on platforms like Reverb.
The Akai CS-F21 is a notable model in the history of consumer audio equipment, representing the peak of the "shoebox" style portable stereo recorder. Released in the early 1980s, this device is a distinct departure from the massive, furniture-sized "ghetto blasters" of the era, offering a sleek, functional design focused on portability and recording fidelity. akai cs-f21
First Impressions: Brushed Metal & Big VU Meters
Before you even hear the tape, the CS-F21 wins on aesthetics. It features that classic, heavy-duty silver faceplate that Akai was famous for. The star of the show is the pair of large, backlit VU meters that dance to the music. The Akai CS-F21, produced around 1982–1983, is a
Tape Compatibility: Supports Normal (Type I), CrO2 (Type II), and Metal (Type IV) tapes. Transport: Single-capstan, belt-driven mechanism. Why this matters: Old chrome tape degrades differently
Frequency Response: Ranges from 30Hz to 15,000Hz for Normal tape, extending up to 18,000Hz when using Metal tape.
- Why this matters: Old chrome tape degrades differently than new old stock (NOS) tape. Being able to dial in the bias manually allows you to record onto cheap thrift-store cassettes and get shockingly good results.

- Set your DAW to loop a 4-bar drum loop.
- Send that loop to the Akai.
- Record the signal coming back into a new audio track.
The wow and flutter is spec'd at around 0.08% (WRMS)—remarkably low for a non-three-head deck. It won’t challenge a Nakamichi, but it will sound better than 90% of the boomboxes and all-in-one systems of its era.
