PERSONAL

As announced on page 5 of this issue, I have made arrangements for a get-together of those interested in the subject of quality reproduction. When it comes to the subject of sound reproduction, the laboratory of the Rola Company is probably the best-equipped in the Commonwealth. I have often visited there to hear the latest in speakers, to play around with the latest of imported gramophone outfits. These visits have always been of great interest and I have often said to myself that I would like all my readers to be able to share such pleasures. Now, through the co-operation of the Rola Company, it has become possible for me to extend to you an invitation to be present at a really fine demonstration which has been arranged for 3rd August. At this party I hope that it will be possible to get down to tin tacks on the subject of what is worth hearing and what is not. Reproduction of the highest fidelity, equal to anything yet done in any part of the world, will be demonstrated, as well as filtered effects to show what is lost in realism when the frequency response is restricted. A. G. HULL.
