According to Christian Gather the CT 232 is more grown up and a bit livelier; also the bass is more balanced and lower. Therefore, the preferred choice should be the CT 232, if space is no object.
The BG 20 is supplied by Visaton with a cone diffuser, a small funnel type attachment. Many full range drivers used to have this type of attachment in the past. For this kit the diffuser has to be carefully removed with a carpet knife.
Excerpt of the review in Klang+Ton 3/2007:
... in comparison to the CT 230: "The first bars showed already that
the fundamental character of the speaker didn't change. Extremely fast and
dynamic, almost like a horn, beautiful flow, an astonishing three dimensionality
and a presence that gives you goose flesh, especially with vocals, are still
the virtues of this design. At the first go, however, the new contestant shows
- no surprise - a lot more bass. It's true that the performance of the CT
232 is a little lean compared to the somewhat fat sound coming from the rather
too small CT 230. But the bass is certainly more realistic and noticeably
lower. The BG 20 doesn't have any problem with the bigger cabinet, the bass
is still tight and accurate at any time and power handling is not affected
adversely. If you know the CT 230 well, you might notice some other differences.
The new addition is a bit more forgiving and kinder in the upper mids and
seems to be more natural and balanced. Also, the tops are less zippy. But
to call this speaker boring would be an insult since the CT 232 is still miles
ahead of conventional loudspeaker with regard to presence, liveliness and
dynamics. " ...
