I’ve really been enjoying the charms of all things Duelund, and I am hard at work writing Part 2 of the Duelund-WRSE Project  for Positive Feedback Online right now.

Sunday Afternoon at Jeff's Place

I had my friends Leo, George, Ron, Stephaen (6Moons), my girlfriend Rosalie, and Santos, over for a listening session last Sunday afternoon. First we listened to some interesting grounding loops from Mark Coles (Sablon Audio) that can be used on speaker cables, interconnects, and the Duelund-WRSE connections. Mark says the grounding loops are basically short loops of very fine gauge litz wire, and act as some sort of ‘trap’ for noise on the signal ground plane. You […]

Duelund CAST Silver Autotransformers for Tannoy Prestige Loudspeakers

In my last post I described the new Duelund CAST Copper & Silver Autotransformers designed by Frederik Carøe to replace the stock Tannoy autotransformer. The same model of Tannoy autotransformer is used in all Tannoy loudspeaker crossovers where an autotransformer is used, and like all of the parts choices in the stock Tannoy crossovers, they were chosen to a price point that would provide good performance without breaking the production pricing bank. After completing the Duelund-WRSE external crossover […]

I know that this is not […]

The Duelund CAST Silver Autotransformer!

Those of you who have been reading about the Duelund-WRSE external crossover project know that pretty much everyone has wanted to use silver wound autotransformers in their Tannoy crossovers to provide the treble energy control (see below), including Paul Mills at Tannoy, Jignesh, Pambos, Frank, and of course, me. The autotransformer in the Tannoy crossover allows the treble energy level of the tweeter to be adjusted over a range of -3 dB to +3 dB by selecting […]
