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,

My Cornwall 4's are easy to mass load from the bottom because of the 3 bass ports at the bottom facing forward. I used lead weights and found that at some point weight became counter-productive and actually boosted and distorted treble. The sweet spot was about 18 lbs of lead per box. More weight stiffened the walls of the box too much and perhaps contradicted some of the resonance designed into the speakers in the first place.
