What are the limits of room correction/ treatments ?


My old listening room was open to other parts of the house allowing excess bass energy to escape and had a high 13ft. ceiling. Clear tight bass and open clear midrange even when loud. My current room, while bigger ( 17 x 21), is boxy with 9' ceilings and a single door entrance. You can really hear the room getting in the way on many recordings, esp with louder complex recordings. Can room correction + treatments really make my current room sound like the old one?

There are internet sites that have room mode calculators, displaying in 3d where standing waves appear in the room, which is determined by the dimensions of the room. You put your room's dimensions into the calculator, and a 3d drawing appears, showing where in the room nodes are located. If you place your speakers and listening position where no such nodes appear, you have minimized the resonances of the room itself. Room treatments are therefore minimized as well.
Many of us find that completely open rooms; let too much bass escape, adds extra strain to amp/speakers, allows noise from other rooms in and visa versa.

You can never under estimate the value of treatment to room...just going through it myself...been having to adjust (only) the bass traps...1" or 2 either way make a huge difference in sound stage and balance...

as others mention well place speakers are crucial...just part of equation that can be frustrating as hell...but so worth it when achieved...never going to be perfect but its a effort that pays off in enjoyment.

It is amazing how the slightest adjustment to speaker location can yield significant results.  Not just placement...also the tilt back of the speaker for proper driver balance at your listening location and the degree of toe-in, if any.  It IS rewarding when you hit the sweet spot in your room.
gik treatment changed the game for me .The best grand i think i spent on audio in forever..Bass traps and treating behind me helped alot,my sofa is against the rear wall so the reflection was a problem
