Putting weights on speakers?

If you really believe that it is beneficial to put something heavy on top of the speakers and your wife understandably dislikes the look of weights, try finding a pair of something decorative, like marble or granite vases or large crystal balls.

Another approach is DIY some Helmholtz resonators of the correct dimensions and nozzle geometry and put them on top of the speakers as there’s a surprising amount of energy directed upwards from the speakers. 🔝

Uh oh...I sense a project coming on...I have DYI cinder blocks as speaker stands. What if I add more cinder blocks to surround the sides and rear of my speakers?

And add a concrete slab across the top, of course.

Hmm...my speakers weight more than 400 lbs. each.  I think adding weight would just turn my spikes into nails that I'd never get out.....
