    Billy,

    Actually, I believe you and I are in the Majority! Full range larger 10+ octave tower speaker systems (w\active bass sections) are not only much costlier to design and implement successfully, but are much more limiting in "complete room acoustical integration" compared to well designed 2-way mains + servo subs (ex: Sierra 2's + Rythmik)! The freedom to "tune-in" and obtain a sharp natural focus of the top end for superior imaging and sound stage with a small cabinet monitor is very advantageous. The freedom to minimize room interaction nulls and peaks with a specialized sub unit(s) placement in the bottom end is also very desirable.

    I can understand there are room set ups and challenges that larger full range tower designs would better accommodate. It will be interesting to see what Dave and Brian come up with. However if speaker placements are not an issue (due to living arrangements, room dimensions, etc), it is hard to beat a finely tuned well matched Full-Range sub\satellite system! For me and my audio 2.1-channel music room and our 5.1 HT living room, we have "live" sound that is always enjoyable! And yes, YMWV!

    And now, back to our regularly scheduled "diamond in the rough" programing...

    Maybe with Dave's R&D with the Diamond tweeter he can help SEAS develop a less expensive version with nearly identical characteristics, like a Cubic Zirconia tweeter........!!

    I also greatly appreciate your discussion of passive vs. active speaker design. That's very illuminating

    - Rob H.
    Always my pleasure Rob! I have quite a bit of experience in taking an existing passive design and converting it to an active design. Subs are easy in this regard, as the filtering is simple, only one amp channel, and one can get away with using lesser quality amplification since basically everything above 200Hz is steeply rolled off.

    For a speaker, I think the only way to do it right is to send the digital signal direct to the speaker, this way one can avoid many of the issues with op amps while also avoiding yet another A/D and then D/A conversion. Problem these days is that receivers and pre-processors don't offer digital outs for each HT channel. When that option becomes mainstream, I suspect we will see many more fully active speakers for consumer use...

    I also agree that a sub is the way to go, but for many people and especially as homes get smaller - subs are not an option.

    Can't believe it's been 3 month since last post on this topic!!

    Dave, now you have finished with Sierra Luna, will you circle back and spend some time on the diamond tweeter tower?

    I expect to be able to start serious work on this in March. We have a brand new website in the works which is very high priority for us...

    Just out of curiosity, will you be looking at a bookshelf or tower design with this tweeter, or both? And will you be looking at a higher level woofer(s) to match the tweeter?

    I too am very interested in these. I just got a pair of Funk 18.0c's and realized a great deal of my towers size and capability are just being wasted.

    I for one would be super interested in like a 3-way standmount though there may be reason I am unaware of to stick with 2-way.

    Either way, my goal is to get a speaker that can meet or ideally exceed the abilities of my towers above crossover. I don't really whah happens below crossover.

    These will be considered specialty products due to the very high pricing of this tweeter. First model will be a bookshelf. A tower speaker with appropriate high performance parts to match the performance of this tweeter will easily be $10K plus for a pair. I would gladly design a tower version if there is interest, but I suspect very little interest due to the pricing.

    I am interested in the towers. Please release both the bookshelves and the towers at the same time.😀
