Diffusion tweak


Is there such a thing as speaker grills designed specifically to diffuse higher frequencies at the source? I think that's what happened anyway. My Zu Omen Defs needed some sort of cover to keep the dust and dander off (3 large dogs and gravel road out front!). So I cover them with  fluffy blankets made of several layers of cotton muslin to capture the aforementioned figuring they were thick enough and anti static.The fabric is thin and light but very fluffy.

Last night I left them on after firing up the system instead of removing them first and damn! The bass and lower mids were richer but there were no details lost.Totally not expected. I'm in the process of breaking in a new Linlia tube which is incredibly detailed and quiet but also emphasizes the leading edges of notes rather than tone as it runs in.Other members say it gets better in time so I wait impatiently:-) So right now the music is warm and beautiful again,but retains the refinement of the new tube and nothing sounds muffled.

Forgot about those.

Just checked Ebay and there are speaker screens/covers available in various sizes.

My early Advent speakers also had screens over the tweeters.

The BBC LS3/5A used the KEF T27 dome tweeter which had a perforated hemispherical metal grill over the dome. 

I used TP on a pair of Castle Isis (tiny piece on the grill in front of the tweeter) until I discovered the root of the HF problem.

Castle had used flat headed screws on the tweeter, but bull headed screws on the woofer (which was closely spaced to the tweeter).

Small felt dots placed on the top two woofer screws worked better.

I really wasn't kidding as it's been a standard tweak for decades on small/bright Yamaha speakers used in recording studios (forget the model, but boy are they lit up).

If you go to Marchall's, you can get woven cap for cheap and put it over your ears. Will work with every speaker.

Try wrapping a length/band of soft porous TP around the speaker (tweeter area).
