Mass loading Tannoy Definition DC10a speaker.

Dear All,

I hope you are all well. I have Tannoy Definition DC10a speakers. I love the way they sound. I have been contemplating mass loading the bottom compartment specifically designed for mass loading. I read that it may help the bass definition but also read it may overdamp the speaker and adversely affect the sound.

My questions:

1-Mass load or not to mass load?

2-If I mass load, should I use lead shots (responsibly) as it has the highest density, or use Atacama atabites, ...etc?

3- Should I fill the whole compartment or do it gradually (let's say 2 -4 pounds of lead shots at a time).

Of note, I am considering adding isoacoustics GAIA II speaker isolators also. 

 

If you have experience with mass loading speakers in general or with the DC10a in particular, I would be grateful if you share your experience and insights. 

Thanks,

I would decouple the speakers from the floor see here I would also put two cement bricks in each speaker: cement bricks shall be 2''x4''x8'' (not clay bricks) see here good luck. 😎
