ML 28 mounting
The ML 28 tweeters have two different sized acoustic rear chambers, which can be easily
interchanged. This technical solution can optimise the acoustic performance in every type
of installation.
These chambers simulate a sealed box environment for the tweeter, and are filled with natural,
non-woven absorption material. The use of the different sized chambers allows you to vary
the “Q” of the tweeter. The Small Chamber increases the Q factor with a sharper frequency roll off
slope; the Big Chamber provides a smoother slope with better low frequency extension.
The Small Chamber solution is ideal for tight
installation space.
When space allows, the Big Chamber
solution ensures the flattest mid-frequency
response and better damping.
- Fix the housing with the two
screws provided; drill a hole for
the wire and insert the tweeter
into the housing.
Note: In case of surface mounting,
the tweeter must be installed
without any rear chambers.

- Always fix the chambers with the screws provided.
- Do not remove the damping material inside the chambers.
