Alex Approaches a Final Design
Well, as if the first designs and prototype weren’t expensive, the final production prototype is making that seem to be a walk in the park.
Hopefully the final design!
I thought the prototype cabinet was boring as hell. Ruby sure looks good so why not hit her with a growth ray and make a larger version.
The first reason not to is price. The main reason to do it is performance – well looks are way up there to.
The complex curves are not easy to build in a way where the cabinet holds its integrity over years. But we figured that out in a way that actually increases the density of the side walls.
The curves also help with diffraction improving image and resonances throughout the main audible band.
Internal bracing is extreme and the aluminum front locks everything together and actually brings the drivers together in a way that no baffle can.
The final product will be Piano Black. Other paint colors can be made on request. Don’t make me kill myself over PMS chips that if off a billionth of a percent aren’t ok LOL.
Concept Under Development
Well, there are several updates on the drivers. You’ll have to wait for now until I’m done with final testing. I can tell you this – they are based in the DNA of Eddie – and take it to the next level – to say the least.
Of course you would expect that when the price exceeds five figures. And speaking of price – I’m not sure yet – but Alex should compete with what was Infinities Epsilon. Take that price and apply inflation and you get the idea.
So let’s talk crossover. The one thing Evoke does, and when I design, is to do what no one does. Build the best and damn the costs. The crossover MUST be phase coherent and the crossover in Alex is really over the top.
I’m not sure of the final design, but it looks like there will be a minimum of 30 and up to 60 parts depending on how high I am when I complete the final design.
There will be no boards with electrical traces that don’t carry much current – just point to point silver soldered with matched components. With the circuit design the Mutdorfs will perform more like there are V-Caps – but without that price.
Standard wiring is teflon, copper and pure silver in various gauges for each driver. If you were to buy a speaker cable it would cost over $500 for 1 meter. Capacitors are rated at 400 volts. The idea here is that nothing will saturate. You can throw a boat load of power at this and I doubt that these components will ever care. That is one reason why Eddie has so much dynamic headroom. He performs like a Ferrari going about 80 MPH.
At this point, if I’m happy with Alex the towers will be all passive crossover. He will be able to be bi-wired – but the upper and lower amp should be the same with the same power rating.
I don’t know yet. Working on it. How’s that for being up front and honest.
Well that’s about it for now. Hope this sneak peak was enlightening. You can certainly throw out a speaker design – but it sounds like it. I want to reproduce music. That’s a bit harder!
