Seen your device and was wondering if a similar type device could be used with a heat dissipator coming forward thru the dust cover instead of out the back. How much heat accumulates in the rear space with the vents inside the rear space instead of going out? Have very little rear space room in present design. How about a similar design as yours with a heat dissipating plate attached to the rear wall but instead of venting into the rear space going outward past the dissipating rear plate...looks do able. Presuming the distance between speaker and rear space wall is little 1-2 inches do you think it is worth it to keep rear space as cool as possible. These will be professional use flown speakers.
