212HTR is 60hz-24khz. Does that mean I will need a sub ?
The way I understand the posts is that a AVR xan drive the noesis but for the 215RT to run the low frequency well, it needs more power ( 2000w ?? ).
Is this incorrect ?
Those are actually very efficient speakers which can produce very high SPL with relatively low voltage. There are several things about your options that struck me. First, I don't know whether I would try to swallow the elephant that is a first-class HT system all in one gulp. I would instead concentrate on getting the basic building blocks in place, and then adding to the system in stages.
I believe that you have correctly identified the three speakers in your front soundstage as the most important ones, but whether you will be content to have an HT system that operates without subwoofers is another question. In theory, the 212RT for instance, can take the place of subwoofers, if you push enough volume through them, and if you don't need to go extremely low. But, in practice, their ideal placement as speakers may not be where subwoofers would have worked best with room modes.
(Seeing your edit, I absolutely do think that you could move down to smaller model speakers. Again, that would leave you more funds for first-class subwoofers such as Cap 2400's. As you noted, most of the JTR speakers are intended to achieve very high volume levels, but they are designed to crossover to subs at about 60 or 80Hz.)
So, I would leave myself some margin to add subwoofers if necessary. You also won't have the same means of increasing bass, proportional to other frequencies, that you would have with independently powered subwoofers with their own volume controls. That shouldn't be a factor for pop music (or for most music) but it certainly can be for 5.1 movies with strong low-bass content. My guess is that you will end up wanting subs, and JTR subs (such as Cap 1400's or Cap 2400's) will be much more powerful for the money than PB16's.
I would perhaps go ahead and add surround speakers initially to get me to a 5.1 system, but honestly, I might economize with respect to adding the other speakers all at once. That is what I meant by adding the most important building blocks first. To me, it's a matter of prioritizing what will have the most long-term impact on your sound, and what you won't ever need to subsequently upgrade, versus trying to do everything at once only to discover that you may have long-term holes in your system.
In my opinion, your front soundstage (and in my opinion, your subwoofers for 5.1 movies) will be the most important components and timbre match will be important for those front three speakers. Timbre match will be increasingly less important for surround speakers, and for the subsequent speakers, simply due to the nature and quantity of content they play. Unless you are using something like multi-channel stereo, I think that most of the time, the additional surround and Atmos speakers will mainly be providing ambient effects and reinforcement to the primary content carried by the front three speakers.
I'm not trying to take you too far away from your additional plan, but I did want to give you some things to think about with respect to prioritization.
