Large uneven rooms, speaker choice and placement


2013-04-02 1:28 am
I've been reading the forums for years but decided it is time to start participating. In the past, I've read numerous posts here that comment on the various design philosophies/elements (box, ported, dipole, monopole, OB, etc etc) and their correlation/interaction with the room. However, one thing that I notice is that the rooms in question, despite having various sizes, are mostly square and rectangular of the type found in typical homes.

This issue was never apparent to me until recently; when I moved into a loft-style conversion (something I'd never thought I'd do). The unit is about 1500 square feet, completely open with 13 foot ceilings. As for the floor plan, the kitchen, bedrooms et all are all laid out in various non-parallel alignments and the distinction between the rooms are not physical. I think my house actually resemble a 2D polygonal whale in shape. It then dawned on me that although a room is typically in a rectangular building, the "room" itself may not always have conforming and symmetrical lines. This is very much the case in many Hifi Shows, DIY conventions, etc etc where the "room" is anything but and at times difference in room treatment can be more audible than the difference of the speakers themselves (this is debatable).

With this in mind, what types of designs do you guys believe have less "room interaction" and whose elements hold well in real-life (meaning non conforming) listening and testing situations.

p.s. My ears have always been a strong supporters of mono-poles and a believer that the driver choices (with any appropriate crossover plan whether active or passive) played the biggest role in determining the final sound/measurements. This idea is starting to crumble down in my new home as some of my DIYs and commercial speakers are not performing (to ear) and measuring as I expected with the change in environment. For a selfish/personal tidbit, the cost and physics to treat the room acoustically is out of my current budget and I feel my next DIY will be a speaker with emphasis on diminishing room-interaction.
