I hope to commence construction on a dedicated HT and am currently finalising the design. Is there any rules/theory about placing subs under the elevated front stage and or the elevated seating area?:confused:

More information needed. Is the are sealed or not? for one. What kind of sub are we talking about? Without any more information, I would say generally this is not a good idea because you are enclosing the sub in yet abother enclosure with its own modes and resonacnces.

How about turning the stage into a big sub? Might work of you want to go the DIY route...

There are a whole lot of downsides to doing this with existing freestanding subwoofers. Custom building the stage or seating area as "the" subwoofer enclosure would be the best bet. The sheer acoustics nightmare of putting a subwoofer in a cupboard (enclosure or room within a room) is not ever going to be ideal.

However with careful design I have seen decent and effectve versions in both vented and sealed (stage and seating areas). Russ Herschelmann has documented and done some of this sort of stuff in old Audio Video Interiors articles. Normally its about WAF ... a bit the expensive way of skinning the cat IMO but understandable. You can also look at bass shakers like the buttkickers if rattle and roll is the goal over hiding sub boxes.

An infinite baffle sub might work for you. If you can make one work, they provide great, low distortion bass, with little intrusion into the HT room.

I don't think there are any commercially available designs; it's all DIY, but not too difficult.
