Yamaha NS-1000 driver diffraction reduction

[handyguy]

I know that there is some worry that sound wave diffraction from the edges of drivers can be of concern. To reduce that on my NS-1000's I cut some wool panels to place over the mid and high drivers. The material is 1/2" natural wool felt and I have attached the laser cut file here if anyone wants to duplicate them. AK won't let me upload the .dxf or .cdr files, so message me if you would like them.

How does it sound?

How is it held down?

I am very busy for the next few weeks so I have not had much time to listen.
At the moment, they are able to be held on with just tension, but I was planning on using some double sided tape, mainly attached to the driver frames.

Although the NS-1000's already have an excellent sound stage/imaging, I believe the anti-defraction pads have slightly improved it.

will give 'em a try. but, can't beat the sound, as is. for me. thank you.

just printed a few copies. now, to cut.

I believe bad speaker connections are one of the worst, easily fixable culprits. I would go with replacing those first and secondly, some solid speaker stands the place them at the correct height for your seating listening positions.

here is my version for testing...using electrical tape... can't tonight.

my impressions: a suppression of the sound levels of both drivers- like having the spkr's pots turned down. once removed while listening, the "live effect" returned. also got a mild skin reaction or itch that persists, from the material.
