that's quite remarkable, thanks for the reply :)

Damn. This makes me hate myself for not going with the ribbons...

While the ribbon is indeed objectively superior, many listeners still prefer the sound of the NrT. So much depends on your source material and your own preferences -- it is very subjective.
And remember, we can upgrade your towers to the ribbons anytime :)

Let's say for the sake of argument that 3 months in to my new Towers, I long to no longer be out-classed by those with the ribbons -- would I need to pack them up and drive them down to SoCal for the upgrade? Could I keep my nrt Sierra 1 center? Should I consider better electronics instead of my Onkyo 3008? I need to stay away from this board :)

How about it, Dave? Inquiring minds, etc... ;)

mal,
Installing the ribbon tweeters requires some internal cabinet modifications and thus it is recommended that we handle it. However, if a customer has some experience with power tools, they can do the upgrade themselves. Installing the tweeter requires routing the inside dimensions of the tweeter cutout. It also requires removal and installation of a new crossover (although this part is rather simple.)

Certainly, but I can assure you that you will eventually want to upgrade to the Ribbon STC.

And this is where things can get dangerous ;) No, you certainly do not need better electronics. However, the ribbon is extremely revealing and about as high resolution as a transducer can get. It will more easily reveal lesser electronics than a dome tweeter.
Going with the ribbons is a very expensive option and while the differences are audible, that difference is probably not worth the expense for most of our customers.
In your case, before making the investment - consider spending a few hours at our facility listening to both versions.

Very impressive indeed, Dave. I note that you didn't publish any harmonic distortion measurements for the ribbon or dome. Did such measurements play a role in your evaluation?

Harmonic distortion for both tweeters is extremely low and so far below what is considered the audible threshold that I honestly did not see a reason to spend much time evaluating.

Thanks for providing this level of detail regarding your new towers. I wish more speaker makers were as forthcoming as you are with this type of information.
