Indeed... the WO24 are 237 $ a piece.... so less than half. That's a lot of money for something that needs way more investigation before any decision can be made.Might be expensive. Madi just increase the price of the PTT6.5 to $411. PTT8 might come close to $500. If dual per side that will run up to $2k for the woofers alone. If it goes much higher than that, I might have to go with WO24P or some SS instead.
From what I’ve read the wo24 isn’t great below 100 hz? Sorry for not having any more reference but I put it off my list because of this.I got 2x 6.5 from the group buy (I think it was ~$250 + shipping each). and then bought 2x used ones later on also for $250 each.
I have built cabinets with the SB 5x8 PR and also lately sealed boxes. Despite not going as low (measures around 85Hz f3), the sealed alignment sounds better, better definition and more pace. It plays loud driven with dedicated purifi class D amps in active crossover. However, when pushed, esp with double bass solo and organ music, the 6.5 will bottom out in my moderately sized room. What's amazing is that the sound is not strained when pushed, they maintain composure until close to bottoming out. in fact, while visually it is oscillating like crazy, audibly i cannot tell it is working hard. Incredible.
The next step is to go deeper (in both sense i guess. ) and built a floor standing full range that can cover the last octave below 100Hz. Currently sub 70Hz is being serviced with arrayed subwoofers. I want the subs to handle sub-50Hz only so I need something that can go down to 50Hz or so, sealed, without any strain. I am envisioning something with dual woofers, dual 8" to dual 10". with PTT mid range and some tweeter on top to be decided. Currently, WO24P seems to be the best option for the bass. $1k for 2 pairs and fairly large boxes.
I am eagerly looking forward to what the PTT 8" has to offer, I am hoping low distortion way down to 70Hz in a relatively smaller sealed box. but fearing the potential cost of entry to get there.
Once that gets built, the 6.5 will end up with surround duties. That will be killer mult-ch setup.

Everything I've read and the few times I've heard it in speakers indicate to me that the WO24 is a superb woofer.
You guys either have much bigger rooms than me or listen waaaay louder. I'm feeling embarassed that, for me the 4" in a nice small box with a sub or two is likely to meet my current needs very nicely.
Not at all... your system i properly very nice. And do notice, that for some, better sound quality can easily compensate for the lack of high SPL. I only have 4 bigger subwoofers, because I like the effortless ability to play anything at any volume. This does not mean that I play loud all the time - I simply chose to pay a lot more to have a bigger system for the few transients that really make smaller systems bottom out and sound strained. Aaand.... to my ears.... bigger systems that are tuned right to a given room, simply have a more impactful and engaging experience with anything you listen to.You guys either have much bigger rooms than me or listen waaaay louder.

And Materials of course. Might be the kids, might be the wife but I actually find THX levels (85dB at listening position for -20dBFS) too loud for me. And I can't physically get more than 2.5m from the speakers.A lot depends on room size, dimensions,
Well... no matter the technology... a 4" is not going to give you much bass. At low volume it might sound ok... but be careful, even though it might take a punch way better than any other 4". Box size.... well... simulate it... there are so many programs and free software out there. Simply try something out and see if you can make it fit your desires.I haven't seen a single 4" Purifi build here. Please can anyone suggest a good box suggestion for a Purifi 4"4ohm woofer
