Hi guys - believe in the Golden Cuboid.

Well, renovations are almost over. A little painting and trim work left.

My new listening room has been worth the effort.

I designed a new floor plan that made use of the former sunken living room ( one step down ) as part of a listening room/HT, when I realized that 9x14x23.5 made an almost perfect Golden Cubiod.

I used the Golden Ratio of 1.618 times ceiling height, that result gives width, then times 1.618 for that result for length.

Then for speaker placement multiply ceiling height times .618 gives distance to center of the woofer from the back wall.

then width times .276 times (width * 5 ÷ 18) gives the dimension from the center of the woofer to the right or left wall.

These are mathematical formula known as Golden Ratio ( 1/2 of Pi ) and a Fibonacci sequence. The three major modes created within the listening space are indivisible, and therefore will null rather than beat

I was very fortunate to have such dimensions to work with. All I had to do was put up a 14' wall and move some doors to get it.
I realize that not many will have the chance to choose their room dimensions - but the formulas work great for speaker placement.

BTW, this is essentially how AES determined their dimensions for the AES standard listening room of 10'x16'x26.

My system ( no other changes ) sounds dramatically better - far more than I would have believed.

1/1.618=0.618.
1.618 x 1.618 = 2.618.
Most excellent number indeed.

Glad to be back.

before we moved a bunch of furniture out it had already gotten dusty -

so now we're dealing with cleaning everything diligently.

it looks like Circletron has picked up on fabinocci stuff pretty well

<grin>
