Yes, this white woofer appears to be quite impressive!Plasnu, one of your "neighbours" owns a nice collection of WE gear.
Best regards!
I imagine my finished product will look something like this, I am skeptical of building it modular, though it would might be the best option. I like the results I've gotten from using straps to secure the speakers I have, to the stands they are sitting on. I may have to build new stands, the goal is to get the 15m at ear level since the horn horn can be angled. Maybe I'll build stands that are weighted and I can strap the speakers to the stand.
I asked the supplier for advice on whether to get the 200 or 350 model of tractrix, he just resent me the price list! lol!
After the models you've shown and some of the readings I've come across I am certain the 350 model is suffice just based off the idea that crossover will be double the cut-off (350*2=600) or more, for the most part, though I'm sure I'll experiment with 500.
You don't need to go modular if you can handle a big cab.
Your listening spot is 15m from the speakers? That's nice, because even with the tractrix you'll have a reasonable sweetspot. 20-30 degrees spread (in the top octave) is usable and it actually makes sense to use a tractrix in this case.
Many waveguides, especially OSWGs won't cut it 'full throttle' in such spaces.
Also, you don't need to worry about the blending between the horn and the TD15M, because at 15m they'll pretty much sound like 1 coherent source, after DSP.
That seems a nice space for intimate (after)parties by the way

No sir, the 15m is the midrange model from Acoustic Elegance! My listening range will be from 1m to 3m. I already know I am breaking the rules by listening at 1m but I am ok with sacrificing coherency for accuracy of spl, in which, dynamic contrast, is the focus of this design. I understand that proper distance is needed for the driver to sound as one, though I forget the technical definition for this aspect, I care not, because, white russian lol!
I am sort of concerned about the AE 15m....I want/need the best midrange available. I have a 4" midrange currently and it is not exactly lacking, do to proper size vs physics so now with a 15"midrange, I need to be more critical in choice of mid range driver. I think you support the 15m and I support you so...I am ok with it, but I have to put it out there in case of doubt.
I sincerely preferred a sealed subwoofer, and the AE 15h is lacking in power handling compared to my desired output (114db-117db continuous at 30hz) I am going to investigate other woofers, though I do hold AE as a standard, due to my belief that inductance is a huge factor for the conclusion of sharp impulse response.
I can notice the difference between 1ms and 5ms, easily. Not everyone can, and I take pride in it. Ported vs Sealed result in significant differences in group delay, with favor towards sealed.
with 625rms @16ohms and 1000rms@8ohms, I have adequate power. I really wanted everything in 16ohms, but it is what it is. If I have 1000rms in 8ohms I can only imagine that there has to be more driver choices to achieve loudness goals with sealed cabinets. I plan to investigate Faital pro first. Any suggestions will be well received as well.
Thanks ro808 for your time. You GM and Cspeiker have been pivotal in this endeavor.

I misread: "ear level at 15m", sorry about that.
I do support the 15M, but wouldn't buy AE myself, because it's too expensive to get those here.
Faital is a save bet for mids. The Deltalite II 2515 also offers tremendous value, but I don't think it meets your requirements.
I am not sure if it makes sense to focus on Faital for sealed subs.
In the US there are plenty of other (and often more affordable) options.
It appears many people like the Dayton Ultimax and Reference Series for sealed subduties.
So you haven't ordered AE drivers yet?

The Ultimax are currently 30% off at PE.
This bad boy looks serious, but it's got dual 2 Ohm voice-coils, so max. 4 Ohm in mono:
Sealed (music): 7 cubic ft. (net internal, not including driver) for an f3 of 31 Hz, f10 of 15.8 Hz with a Qtc of 0.62

An externally hosted image should be here but it was not working when we last tested it.
Listening at 1 - 3 M at high power, with horn? Horns are bad at close distances and even worse the further you go haha, they have a sweet spot where the XO occur somewhere.
Why do you want to become deaf listening at 100db+??? btw at high pressure levels 3 ways are always better because they beam less, the more output the more beaming on the woofers.
who cares about the drivers and power output if the room is less than 20' x 20' x 20' anything below is a big compromise on 30hz waves for the half wave sound...
my room is 30x22x9, nothing much I can do below 30hz

Not sure what your space allows but two Stereo Integrity HST18's sealed would probably get you where you want to be but you would need a lot more power. Getting those kind of dbs at 30hz sealed is gonna take a lot of power and surface area. I run one of them on 2400 watts in 4 cu ft sealed and at high volume my room starts to come apart...literally.
Yes, you should ideally add a tweet to a tractrix.
Personally, I avoid supertweeters, but I don't use tractrix horns.
That's what I thought, but I guess Camplo has specific reasons for this.
Your statements with regards to <30Hz make sense.

On low frequencies in small listening environments.
It's a myth that you can't reproduce frequencies longer than the dimensions of the room. Car audio proves that wrong.
You just pressurize and depresurize a small room with very low frequencies.
The reason people think you can't do it is because of room modes. Once these have been taken care of, your fine.

Hey camplo, dont get hung up on driver inductance if the woofer covers the frequencies needed. I read the same article that you probably did in my quest for the best bass possible. Driver inductance does affect impulse response, and it seems logical that impulse response would predict driver acceleration/jerk ability (notice I didn't say speed ),
BUT, any crossover will affect the impulse response in the same way!
Think about it, one finds the perfect low inductance driver, then puts a huge inductor on it for the passive crossover!
Even with an active setup, it will affect the impulse response in the same way. That's just the result of not having treble in the signal.
Try it with REW. Run measurements on a driver with and without a crossover and take a look.
It's very likely that I am missing something on this theory. Hopefully someone smart chimes in if so. I'd love to understand it better if I'm mistaken.
