This is a teardown of a pair of AUDIUM Comp 7.2 Passive, exquisite speakers, with a much better and authoritative bass that I was expecting given their size. These speakers belong to a good friend of mine and I was taking the below pics while I was changing the backplates with the binding posts and make them EXAKT compatible.
They look very much like the Comp 5 generation reviewed by 6moons back in 2009, at least their look and the woofer placement.

Speakers sound very well in the room from the first picture, for some songs there's not even need for the subwoofers. Unfortunately I can't find out my in-room REW measurements, but if I'll ever find them then I'll definitely post'em here in the thread.
The works I've done to these speakers was to remove the original binding posts (that were containing a few passive components, part of the entire crossover) and to disable the two drivers inside each speaker, then to install new binding posts dedicated for LINN EXAKT. This means that the drivers are directly exposed to the two amplifiers (one for each driver), without any analogue filters (crossovers) in between, so everything relies on the digital filters developed by the LINN manufacturer. Too bad that the custom digital filters were not quite perfect and the bass delivered to the full-range driver was simply too much, so I needed to revert everything back on how it was with the original crossover filters and binding. My friend purchased meanwhile a pair of Kudos Super 20a speakers that works perfectly with the LINN EXAKT technology and with the dedicated digital filter and now he's very happy.
