It’s not really a mass issue for the tops of speakers. It’s placing something that acts like a diode and allows the otherwise trapped energy in the speaker cabinet to rapidly escape to the outside air via a path of least resistance. This is why things like those Totem Beaks or cones, especially NASA grade ceramic DH Cones, very hard but not very massive, but massive enough, are often so effective placed on top of speakers. 🍦 There used to be a product Tekna Sonic that was purpose built for attaching to speaker cabinets that accomplished the same thing. For the same reason cones can often be placed on top of the electronics chassis or tube traps and accomplish the same sort of thing, dissipate energy rapidly from the system. Crystals also dissipate mechanical energy in similar circumstances.
Why is good, deep bass so difficult? - Myths and their Busters
This is a theme that goes round and round and round on Audiogon. While looking for good sources, I found a consultancy (Acoustic Frontiers) offering a book and links:
http://www.acousticfrontiers.com/guide-to-bass-optimization/?utm_source=CTA
Interestingly: AF is in Fairfax, CA, home to Fritz Speakers. I really have to go visit Fairfax!
And a link to two great articles over at sound and vision:
https://www.soundandvision.com/content/schroeder-frequency-show-and-tell-part-1
https://www.soundandvision.com/content/schroeder-frequency-show-and-tell-part-2
Every audiophile who is dissatisfied with the bass in their room should read these free resources.
Let me state unequivocally, deep bass is difficult for the average consumer. Most audiophiles are better off with bass limited speakers, or satellite/subwoofer systems. The former limits the danger you can get into. The latter has the most chance of success IF PROPERLY IMPLEMENTED.
The idea that large drivers/subs are slow is a complete and utter myth. Same for bass reflex. The issue is not the speed of the drivers. The issue is usually that the deeper a speaker goes the more it excites room modes, which the audiophile is then loathe to address.
Anyway, please read away. I look forward to reading comments.
