Will you be benchmarking (or probably already have) other DIY 3-way designs.
There are many other great tweeters. The Accuton C12, C23, Dynaudio Esotar, Raven R1, Scanspeak Revelator come to mind immediately.
The sad truth is these amplifiers are DESIGNED for a 4 ohm minimal load and higher current capacity. This limits their output to 60 watts. Obtaining 100 watts from those same general components in the same general configuration would require the designer to approximately double the amplifier component count.
I believe it's common for folks to desire a very minimal speaker crossover, but sadly uncommon for folks to desire a very minimal amplifier design.
This speaker will be BIG, but will not grow larger than 5 cubic feet.
My current speaker uses Dyn Esotar T330.
do you find the 'newer' tweeters that extend into 40Khz or above to warrant 'sensable' improvements over the traditional tweeters that extend only to about 20-25Khz range.
While I am still a novice in basic amp design concepts, but I do learn from experience that 'more' properly built amps (often heavy and expensive, too) while output the same watt, it is capable of rendering an open and relax 3-D soundstage with much ease than the others.
May be that's also why many friends of mine have multiple pairs of speakers paired with various brands of (dedicated) amps.
Since this is meant-to-be the ultimate 3-way speaker, that is truly the least of the concerns.
Is there any preliminary speculation of the dimension yet?
How big of a room is this 3-way speaker designed to perform in?
However, can you explain why the 200wpc amp sounds better than the 35wpc push pull when the peak consumption is 30 watts? I believe the answer lies in the ability for an amplifier to push a GOOD 30-40wpc with most speakers. I beleve most amplifiers fail in this regard.
While there are some significant factors in room construction that DO effect bass response, a big 3-way speaker can be used in a very modest room.
I just sent my Golden Tube SE40SE to Soniccraft for the "full Glowacki" upgrade. I think this amp might be the real deal after Jeff's work.
However, it'll be a first in many regards. All drivers will have underhung motors, stiff cones, neo magnets, and high sensitivity. Unless there something goes awry, this will be the configuration.
A big 3-way speaker often prefers to perform in a bigger room. As you already point out, the room dimension will affect bass response. In a small room, which can't reproduce the bottem end, it will most likely to create bass booming problems. What will be the minimal dimension that the speaker needs in order to 'breath' comfortably as its design intended?
But during the demanding moments, amps with more headroom may be useful.
Does this mean the accuton underhung drivers are the top candidates for now?
Dave, this is looking more and more interesting. Perhaps I can swing by Dennis place again to audition the prototype when it is ready!
...I have not heard any Accuton woofers but the C79-6 seems ideally suited ...
However, if you are interested in arguably the very best speaker currently made, I suggest you visit Jim Salk in Detroit www.salksound.com.

I am not sure if they are the "best" out there, but I am very willing to say that they are one of the "best" out there in terms of sound, quality, and value.
Umm, Dave, have you heard the Orions, lately?
Also wanted to say "kudos" to you for recognizing a peer of yours and not starting some flame war or feeling the need to start a turf battle.
Yes, but they are expensive. However, like the 1801, I am building this speaker for me. If somebody else wants one... okay icon_smile.gif
If these accuton drivers are really all that, I actually would seriously consider dropping extra dough
Too bad I haven't found anyone has one in Baltimore/DC area, otherwise I would love to audition it.
Thinking of xover, will the 3-way have a passive and/or active oxver?
In term of cabinet, have you had much time to experince with different materials? Are MDF and hardwood still being used as the primary material for cabinet?
