A few thoughts.......
Equipment up front with cloth doors typically presents problems due to heat. Cloth doors may be better then solid wood but only marginally, nothing to promote air movement.
If you vent pulling air in, the cloth doors turn into filter, works great but looks like a used filter in no time. If you blow air theres no filter effect, works great, but then you could raise the temp of the room. Venting lower front is not as easy as venting side or back built-in cabinet or even better, closet.
Where have you decided to place the subs? I try to keep my subs away from my rack when ever possible.
Then there's the distraction thing.....looks great during Star Wars and a few others but for everyday use......Plus equipment up front makes it look like a demo room.
Just one mans opinion ..... Mark
