sir Paul, those DVD cabs @ front corners are shelves type?.... di ba, those corners are best locations for bass traps? and shelves can be located at the rear wall to serve as diffusors as well. it's also more accessible to organize your collections... 
those protruding columns can be easily covered by wall acoustic panels but overall layout.. maganda sir ang Ht nyo..
Congratz!... 
just my 2mamera.. 
Hi Mon, thanks for the feedback.
The front DVD cabinets shown in the layout are actually not at the front corners. All the four corners inside the room will be treated for bass traps. The DVD cabinet design isn't finalized yet but it won't be the usual open shelf type. Most probably it will be a closure type to blend into the whole wall otherwise it may stick out like a sore thumb.
Yes, initially I intended to have the DVD cabinet shelves built into the rear wall as diffusors but unfortunately my room size limitation make it inaccessible esp after the second row seating is setup (too near the wall). Also, i have to deal with the columns problem.
Hence, will provide separate diffusor treatments at the rear wall.
Speaking of the false wood columns, they aren't in the initial layout....hay to make a long story short...our architect made some bobo & the room ended up with five (5) protruding concrete columns with different sizes (pls see floor layout in Reply #366) ...really ugly. So, I just disguise the colums with fake wood columns....a total of six (6) to balance it out.
Will see how it goes & in the future might treat them with wall acoustic panels.
