Hi sd vidiot,
To add to the above comments, at Axiom we anticipated "bleed-through" as a potential problem with in-wall speakers so when when we developed our in/on wall lineup, all of the Axiom models have a sealed "backbox" (sealed to the interior of the wall, that is) to prevent rear-radiated sound from venting into the wall cavity. The ported models are ported to the exterior in the room in which the speakers are used. By using the back enclosure, we could also make the performance and design of each in/on-wall speaker consistent rather than having it be influenced by the variables of interior wall cavities.
Regards,
Alan
