Robert, I'm responding here to to your questions that were in a different thread where you asked:
"It's great to see the advancement Avalon has made in speaker design,but what can you tell us about the upcoming Sentinel update and the New Saga speaker":
"1.Will it incorporate tesseract technology?" Yes, many things that were learned and developed in creating Tesseract will find their way into the new Sentinel and the Saga. Crossover technology and parts choices certainly will play a big role. A lot was learned in the Tess development that can work into the crossover designs of these speakers. The current Indra Diamond and Indra Ceramic actually already has Tess crossover technology incorporated and they are fantastic sounding.
"2.Will it use tesseract drivers?" Those models are both still in development and I don't think it serves anyone to comment on specific design details for something thats in development. So many things can and will change in the development process that it's just not wise for me to comment on a lot of specifics like which drivers will be used, physical characteristics, etc.
"3.Will they be more efficient and amp friendly than the older designs?" Neil has told me that he plans for these (and future Avalon models) to not dip down below 4 ohms so they are easier to drive. With Isis you need an amp that can handle more of an impedance dip. Saga and the new Sentinel should certainly be easier to drive.
"4.Will they be passive or active?" I'll say that the current plan is for both to be passive. Originally, the new Sentinel was going to have an active sub but the design has now switched to passive on that one. Saga certainly will be passive.
"5.Will they be priced between the tesseract and the Isis?" Correct.
"6.When will they be available to the public?" I'm not in a position to say at this time since both are in development. They of course won't go into production until Neil is completely happy with them and I just don't know when that will be. Sorry I can't be more specific....and a guess on my part really is of no value to you or anyone. I know that there already is a queue of buyers for both and so of course we plan to go into production quickly as soon as the designs are finalized.
I hope this is somewhat helpful...sorry I can't get much deeper into details at this time. I will post updates here though when I have firm details.
