    I have recently purchased a pair of Mordaunt-Short 904 floorstander speakers. In the manual that accompanied them it states that they can be ballast loaded. A number of questions:

    * What does ballast loading involve - there is a cap on the back - does it involve putting something in the base of each unit?

    * If this is correct, what is the best material to use?

    * What effect does ballast loading have on the sound?

    Thanks for any help,
    JB

    I filled the bottom of my Tannoy MX-3's with sand. The result was greater weight and more punch in the bass. Well worth the investment IMO. I purchased Kilm dried sand from B&Q - £4 or so a bag.

    As mugsy says, buy Kiln dried sand, NEVER use sand from the beach!!!
