bass trapping in the corners and rear of the room is what you should deal with first - considering bass is the predominant feature in dance music you need to be able to hear this correctly. problem is though unless you have a large room and are good at DIY its quite tricky! a quick and dirty solution is to position a sofa or something at the rear of your room - that will suck up a lot of the bass.
when you consider how big a bass wave at 20/30 hz you need about 3/4 ft of dead space to trap it effectively.
check out www.electroacoustics.co.uk - hes the guy who did our studio spec - and its immense. basically uses rigid boards to trap the bass at certain frequencies and turns the energy into heat - very cunning stuff.

I felt that treating all my corners with bass traps - wall to ceiling and wall to wall (except my back wall due to the placement of my window and doors) would be the best thing to do first. In parallel, I treated all my first reflection points - behind the monitors, to the side, the ceiling and some of my back wall (a door is in the way for another panel so I'll just crack it open to deflect the sound away from me).

Now, this sounds awesome as is. Keep in mind that I don't have my superchunk bass traps in my front corners yet. They will be coming relatively soon though.

Now, after all that, that is my new base line for the acoustic properties of my room. And, this will DRAMATICALLY affect the acoustics of the room and make it a better environment for both listening and mixing (the difference I've heard so far is phenomenal - too bad I don't have any data to support this - its all subjective at this point).

Up until this point, everything was focused on broadband absorption. After everything is installed, I can take a new measurment to find my left over problem frequencies (usually in the low end) and build things that focus on specific frequencies like slat resonators and other bass trapping devices that focus on a more narrow band.

I would recommend you first focus on broadband absorption like I did, and if further tweaking is required, you tune your other treatments to that particular problem frequency. This is all assuming you do not have a huge budget to get a professional to come in and do it for you.

Just my 2 cents...

Regarding the equilateral triangle, all I have to do is lean back a little
