How far and wide? NSMT speaker placement

zazouswing, well said + one.

If you have the room placement liberty I’ve found the Golden Ratio formula from the Cardas website to be very effective in my last three rooms despite those rooms not being exactly rectangular and slightly different.

Since my speakers are designed for very slight toe-in may have made the Golden Ratio formula a good fit. Using the Golden Ratio with aimed toe-in should still provide good bass loading within the room. Your listening position may vary.

I used the mobility of an wheeled office chair to optimize the listening position from the speakers location.

Get out your tape and good luck.

I bit off-topic, but I’d like to give a plug for high accuracy measuring devices.

I use a Leica Distro Last Tape Measure to locate my Martin-Logan speakers in the room to within 1/8-1/16 of an inch from the back and side walls.

I then use a digital level (Swanson Tool Co SVT200 9 Inch Savage Digital Magnetic Aluminum Billet Torpedo Level) to get the vertical "cant" of the speakers equal to within 0.1% of a degree (I prefer bolt upright).

Both of these make a audible difference, are one-time purchases, and are generally useful around the house.

+1 yes, very good point.  Very accurate placement can be very important to get the most out of your speaker.

I used planar speakers for around 30 years… they are really sensitive! 1/8” can effect sound in a very big way. But most speakers are more or less effected.
