Sierra-2 Development Thread

[davef]

With the center to center driver distance inherent to the Sierra-1 (= Sierra-2) front baffle and a crossover point of 3 kHz or higher, the characteristics I describe are pretty much inherent without considerable manipulations in the crossover which would likely compromise the design in other ways and again, would go against anything Dave has done in the past.

You are correct in your statements here -- high crossover points in combination with large center-to-center spacing can result in major vertical off-axis issues. It is for this very reason that we were very specific with Aleksandar on what our requirements were for the capabilities of this tweeter. Vertical lobing will occur with any speaker that uses more than a single transducer in a vertical array -- it all depends on vertical off-axis angle. With the Sierra-2, vertical lobing only presents itself at angles that are greater than the vertical dispersion capabilities of the ribbon tweeter itself. The issue you bring up has and always will be a major factor in all of our designs, and careful attention has been given to this with the Sierra-2 as well.

Hope this makes sense!

Seeing as Dave gave the final approval on the final component, pricing should be here soon. At least according to his own words!

C'mon Dave......we know you want to spill the beans!!

I want to have all components in hand before we announce the pricing, just in case we need to make any last minute changes to the crossovers (which are already here)

The components in the Sierra-2 are expensive, a custom RAAL ribbon tweeter, custom SEAS woofer, bamboo cabinet, optimized crossover with air-core inductors, metalized polypropylene caps and non-inductive resistors...

Let's have some fun, anyone care to take some guesses at what the final pricing for a pair will be? We will send an Ascend baseball cap to the forum member who comes closest. This is for a pair in our standard natural finish.

I'm guessing $1650/pair

Hmm. Sierra-1 w/NrT is $1148. RAAL upgrade above the NrT on the Tower is $700. And there's the new woofer. I'm thinking a little higher ...

$1898

I'm hoping $1450.00
