So I am currently working towards this concept for my Macondo (see below) and I have just the Upperbass horns left to turn and prep.
I am thinking about how to best integrate the DSET with Macondo and have come up with something like this…
Perhaps it will be possible to build the amplifiers as part of the frame of Macondo and then package the power supplies so that they will fit under the Upperbass Horn. This will hide them from view and reduce the footprint of the entire audio system in the room.
Romy, the thing that worries most is heat. I am concerned that the 6C33C’s and other tubes will cause the drivers above to warm too much if I snuggle the tubes in too close to the frame and I am hoping for your input here. Are you able to give some indication from your experience with this gear?
I thought that I would set the amplifier section on a platform to the inside of the horn stack (because the bass will go on the outside of the stack, and run cables from the hidden away power supply up to the platform. Some effective vibration isolation will be installed for both the power supply and the amplifier.
With this arrangement I could hard-wire the speaker cables and the only cables in or out would be a power cord and the interconnects.
I had also thought about splitting the amplifier section into three as follows: 6C33C x 3 Channels down with the power supply; DHT channel right next to the MF horn; two single stage channels up high next to their drivers. However I thought it best to have the crossovering all in one place. A split amplifier section would require setting up two more bias supplies but I am sure that is achieveable.
Regards,
Anthony
