Speaker placement

@oldhvymec 

That must be a helluva room those speakers went in! 😂😂. I didn’t get to the part about room treatments with Bob. I wanted to get with everyone here first. I’m not sure if he does any measuring or if it’s all by ear. 

By ear? Sorry OP no measurement?

You LOST ME.. How you gonna know what the heck is going on in a "DIFFICULT ROOM" (Your quote not mine) if you don’t take at least some SPL readings in the corners and seated position. HIGHS and lows it will tell you a LOT. 10 to 1 right in front over your head, treatment there alone, will tame all kinds of HF energy.

The BACK wall, normally the first reflection point is pretty important and Major control point for OVER loading a room. Decay rate is VERY important.. How LIVE is that flippin’ room and where are the hot spots..

3 way to heaven. Trap a frequency, control a frequency, or LOSE a frequency. It still boils down to room correction mechanically and tailoring the sound with Tone controls (parametric and some graphic EQ) and if needed time delays. Heavy curtains are your friend believe me.. You can draw or open for room correction and they look nicer than the stupid room treatment panels.. Some are, ARE, JUST UGLY dude...:-)

Corner traps. Some are a WHOLE lot better than others.

Master M can tune in.. He always has a goodie or two.. helmholtz TECH

Difficult rooms, 6-7 foot ceilings those are REAL tough..

Kitty Corner in the room is that an option? Decware https://www.decware.com/paper14.htm has a great article about just that type of room..

It’s all pretty cheap BUT it does take time to learn it.. Week or two you aught to be a pro.. LOL Charge BOB 500 and a smaller fee for travel..

I was referring to Bob if I was to use him not knowing if he took measurements or not. I do have treatments on the walls and ceiling. Have a look on my systems page. I would love to hear your opinion. So far I have run the audyssey xt 32 room correction that came with the Marantz 8805 in the position that the speakers are in now. My next thought was to try the sumiko placement method and see how that sounds. Would I run room correction after each new placement? 

I've come to conclusion Audyssey sounds best when it is never used above 500Hz as it can cause ringing. Perhaps why there is a 2kHz dip by default.
