Hiding 700 Sub Module. Possible?
I would like to get a 700 sound bar with a sub but I need to make the sub "disappear". Three options I'm thinking about are:
1) Build a cabinet to hold a 700 sub module and mount it under the floor with the sound ported into the room through a floor vent.
2) Find a legacy Bose Acoustimass bass module, remove the front cover and mount it directly under a vent in the floor facing up into the room.
3) Build a custom sub to mount under the floor and port into the room through a floor vent.
Option 1 would most likely reduce the efficiency of the 700 sub module, but could it still be adequate for someone that doesn't need to shake the room, just fill out the low end.
Option 2 would require finding an old Bose sub with two drivers and sound port facing the front. I'm not sure of the model, but I've seen pictures.
Option 3 would require knowing the detailed specs in order to tune the home-made sub properly, e.g., crossover settings. Is that even possible to get specs with that detail from Bose?
Any help or suggestions would be greatly appreciated!
