For AUCTION here is the result of a "LABOUR OF LOVE PROJECT" which took many years to complete and coupled with the right HIFI equipment, these speakers give results dreams are made of.
Two 15" Monitor RED Dual Concentric speakers with close serial numbers - Almost an Un Obtainum in today's Vintage HIFI market.
Silver Duelund Wiring was used from the connections for the HF and LF drivers to the binding posts of the external crossovers.
Connex Binding posts were used for the external crossovers having used the ‘bypass’ method, thus binding posts are not part of the circuit.
All Inductors, Capacitors and Resistors are from the DUELUND Range.
For the HF and LF circuits PIO CAST Copper Inductors, capacitors with silver resistors were used.
For the parallel running Notch Filter in the HF Circuit, the capacitor from the DUELUND RS range was used with a WPIO Inductor.
Silver wiring was used in the HF circuits, with copper wires in the LF circuit.
Custom made of 25mm solid Jarrah Wood (A hard wood only available in the south west of Western Australia) - as per Tannoy’s GRF-R plans, including the fitting of the very important 'Teardrop' at the beginning of the horn chamber to avoid the mixing of High and Low frequencies through the horn chambers.
The rear removeable panels had been strengthened with 40mm in depth frameworks, the void spaces filled with sand and another 25mm solid Jarrah panels to avoid mechanical vibrations and for a tight and beautiful bass.
THE SPEAKERS PLATFORMS:
Made from 40mm Perspex for the speaker cabinets to sit on, custom made solid Brass Spikes connect the 40mm Perspex to the floor.
For additional focus on HF, a pair of Tannoy ST-200 Super Tweeters with KONDO silver cables to the connections of the HF binding posts of the external crossovers are included in the package.
I live in Perth - Western Australia and local pickup is preferred, but can ship Australia or worldwide (proper shipping crates would be made for shipping) at buyers cost.
Low Ballers will be politely ignored and any questions from serious and interested buyers will be truthfully answered.
Due to high cost of speakers, no paypal unless buyer adds the 4% for international transactions.
Thank you for looking and HAPPY BIDDING!!
