No need to bank. After Purifi release the tweeter in 2025 we should speak @lrisbo about a Kickstarter or GoFundme compaign to see what kind of demand there is for a PTT largeX
My guess is that the combined demand could well turn out to be larger than for all other Purifi drivers except the 6.5".
It seems to be that they wanted to build their experience with the 8 and 10" first.
And from a marketing stand point if there was a 12" not so many people would buy the 10".

I have my doubts. I don’t have any sales figures, but when I look around, the world has moved to smaller speakers…

I guess we could say the world has moved to In-Ear-Monitors - but that doesn't preclude there still being a big market for 12" in things like home cinema and subs etc.

Happy New Year's eve or day (depending on where and when you are reading this) to all! Wonderful music via HiFi to all in 2025.
My observation on the compact (4 to 8 inches) vs. large (12 inches and over) woofer question is to point out I see exciting developments in both compact living room friendly and jumbo big room venue architectures. Pictures are fun, here's a few examples.
After waiting a couple of years in my excessive projects queue the PTT4.0s first prototypes have seen the light of day.
The little protos are too small to fill the top plate of my stands!
At the other extreme I continue to follow with glee and admiration the work of Devon Turnbull's OJAS. Beyond being personally drawn to Turnbull's design aesthetic I find one aspect of his practice absolutely counter intuitive. That is taking what I would judge to be the most nich and off putting to general public stereo system architecture (giant speakers and triode SET amplification with LPs and reel to reel analog sources) and making it chic. Devon has taken this esoteric HiFi architecture out of the bachelor audiophiles' man cave and into the galleries and museums of New York, San Francisco, and other centers of taste and trends worldwide.

To pre-answer the question the subwoofer shown above is the Fostex FW800HS, 31.5" Super Woofer present US retail price for driver $5,909.00. I guess that will cue someone to say they are waiting for Purifi's 30" driver.So there we go, some woofers are barely as tall as a favorite coffee mug while others can make MTM speakers using a pair of 12" or 15" drivers per side look "reasonably" sized. My world has room, time, and place for both extremes. My personal living space appreciates the SOTA bass from reasonably sized enclosures Purifi's breakthroughs provide.
It will play low ( LR4 1KHz ); It will play loud (>110dB /m (reference 10KHz) and it will have a low and flat impedance curve (4-5 ohms)
As usual the distortion is ultra low (H3 and above around 0dB with 2.83V drive) so most people will be measuring their noisy signal chain, not the actual tweeter.
So again we hope @HiFiCompass
can measure it for us again.
It will come in the usual faceplate sizes Ie. 104mm but hopefully be adaptable to a custom baffle/waveguide without too much bother…

The first batch is apparently shipped. No idea yet when mine are shipped.
Will open a new thread when arrived.

I look forward to seeing the tweeter on the website. Is there any thought to developing a dome midrange (sorry if this has already been addressed)?
That's great news - hopefully it means the next Purifi release will be the 12" woofer 🙏 🙏
That raises an interesting question for me - what would we want from a Purifi 'mid-dome', over and above their present 4 inch mid offering? Or what would we like to see that differentiates there possible 'mid-dome' from the rest of the 'mid-dome' market?
Compared to the PTT4.0, I would like much better HF dispersion and more efficiency. Pushing the initial breakup out of the typical use band would also be nice, though this is not a big deal to me since the breakup is well controlled in the 4". For differentiators in the market, application of the Coherer technology (if possible) and ability to be used lower would be great. So, a Bliesma M74 with the coherer and ability to go to, say, 400 Hz. Or, even 300 Hz. If it ended up being bigger (M100), that would be fine. Am I asking too much? 😀
a 3” or 4” dome will give better sensitivity and dispersion compared to the 4M. Also likely lower distortion. The coherer tech would allow xover up in the 4-5kHz range by countering the narrowing directivity. it is an intriguing idea 😆 cost scaling vs dome size is just not so attractive compared to a cone driver due to the large motor size.
I don’t see how the coherer tech would make it go deeper.
