[[Image:clavinet d6.jpg|thumb|The Clavinet D6, the most popular model, was introduced in 1971.]]

The Clavinet D6, introduced in 1971, continued the case style of the C but is covered in black vinyl leathercloth and the upper surface of the instrument is teak veneer, which was cheaper to manufacture.{{sfn|Lenhoff|Robertson|2019|p=252}}{{sfn|Vail|Carson|2000|p=274}} The instrument came with a removable lid used for transporting, which also had space to store the music stand. The D6 allowed a more versatile sound election, which could be selected by six rocker switches to the left of the keyboard. The left four switches are concerned with tone; "Brilliant" and "Treble" activate a [[high-pass filter]], while "Medium" and "Soft" activate a [[low-pass filter]]. The two right switches are marked "AB" and "CD" and control which pickups are selected. On the right was a mechanical mute slider.{{sfn|Lenhoff|Robertson|2019|p=252,256–257}}

The final E7 and Clavinet Duo models reflected several engineering improvements to make the instrument more suitable for loud stage use, including improved shielding to avoid electrical noise. The E7 was introduced in 1979. It has a black vinyl leather cloth covered case with a rectangular profile with rounded corners and a removable metal lid to protect the keys and control surface for transport. The control panels at the left hand end of the instrument include those found on a D6 along with a sliding volume control.{{sfn|Lenhoff|Robertson|2019|p=252}} It included support brackets so it could be mounted on the rounded top of a [[Rhodes Piano]], a popular combination of keyboards at the time.{{sfn|Vail|Carson|2000|p=274}} A number of D6-labeled instruments were made in the E7-style case and include D6 logos on the control panel and the removable tuning cover. These are known as D6-N models, the "N" denoting "new".{{sfn|Lenhoff|Robertson|2019|p=252}}

The Clavinet Duo model was first produced in 1978. It combined a clavinet with the Hohner Pianet T in one compact, albeit heavy, instrument.{{sfn|Lenhoff|Robertson|2019|p=254}}{{sfn|Vail|Carson|2000|p=274}} A foot switch allows the player to switch between clavinet, pianet, or a mixture or the two. There is also a "split keyboard" mode that allows either instrument to be used in a particular range of notes. There is a stereo output jack, that allows either a mix of the two sounds or each individual sound on one half of the stereo channel. It used a black case in the style of a Clavinet E7.{{sfn|Lenhoff|Robertson|2019|p=254}}

By the time the E7 and Clavinet Duo were being produced, [[polyphonic synthesizer]]s had become popular, and electromechanical keyboards were beginning to fall out of fashion.{{sfn|Lenhoff|Robertson|2019|p=252}} The final models were manufactured in 1982.{{sfn|Lenhoff|Robertson|2019|p=254}}
