mikeyw,
Although I have never listed my components here, here is a break down of my HT system.
My TV is a Sony KDF-55WF655 LCD RPTV. My receiver is a Sony STR-DA7ES. The L/R front speakers are Athena AS-F2 floor standers, the center channel speaker is a Mirage OM-C2, the surrounds are Mirage Omni 50B's. I use a Sony AVD-50ES for my DVD player and my CD player is a Cambridge Azur 640C. Within the next few days I will be adding a Sony TA-N90ES amplifier for my front speakers.

Joe- Have you considered weighting the Athena AS-F2's to keep them from dancing for joy after the TA N90ES aka The Beast assumes the duty of powering them?

Maxx,
It's interesting that you bring that up. I have been considering what to use to try mass loading the AS-F2's. Not only to keep them from dancing with joy but also to improve the sound.
I know that there are commercial brass weights etc. but I am open to suggestions from all.The top surface of the speakers are approximately 9.5" X 12"

Joe- Some people prefer weigting their speakers with lead weights because they have a lower Resonant Frequency than brass.
As far as Mass Loading speakers goes I've had good results using Granite slabs. In fact I listened to a $40,000 pair of B&W Nautilus speakers a while back which were coupled to slabs of Granite. If "the most accurate speaker ever made" is Mass Loaded onto Granite that seems like a fairly good recommendation.

Maxx,
Thanks for the reply. A granite slab would be a good choice. I am sure that I could find pieces that would fit on top of the Athena's.
How much weight do you usually start with, or is the amount that critical?

Joe- It would probably be advisable to get several 12" X 12" Granite slabs and experiment to see how much weight offers the greatest sonic benefit.

Gentelmen, I am confused! The $40,000 pair of B&W Nautilus speakers were coupled to slabs of Granite by sitting them on the slabs, right? Joe, you are talking about placing granite slabs on top of your speakers, right? How can both be considered "mass loading"?

John,
Yes, I am talking about mass loading by placing granite slabs on top of my speakers for resonance tuning. De-coupling or coupling the speakers to a solid mass at their base is another form of tuning but not mass loading. Was that your question?

John- Mass Loading is the Rigid Coupling, Gravity Coupling or Decoupling of speakers or other equipment onto a rigid high mass platform like Marble, Granite or
Concrete.
Adding weight to the Mass Loaded equipment or speakers is a seperate consideration.

John- Thanks for bringing that up. Sometimes we get to throwing terminologies around and I can see where their meanings could be misinterpreted.

Have you heard of the recommendations of Mapleshade? They recommend using air-dried maple blocks for mounting and mass loading. They also produce special brass spikes, too. They claim maple (not kiln-dried) has superior acoustic properties. I'm a little dubious on the actual mass being enough to do much.
Has anyone tried using maple this way?

The_Ish316- Mike Vans Evers says that he experimented with 17 different kinds of wood including Maple and found that they each had their own effects on Resonance.
Maple may work for you and another material may work better. The only way to find the best application is to experiment.
There just isn't a silver bullet when it comes to Resonance Tuning. I Resonance Tuned 21 pieces of equipment in my Audio system and no two of them were done exactly alike.
