Hello- Joseph released a baffle design for a speaker that was never fully released as a box and I’m interested in doing the build. 2 Way floorstander… can anyone point me in the right direction for a resource to box design? I know it should be pretty easy as we have the baffle…thank you!

2422. It’s the baffle of an older design. He provides the baffle CAD and the rest is up to us… I’ve just always really liked that baffle. Also I’ve asked him to quote a crossover as well…it’s the Purifi 6.5 and SB Be…

Am I lost ??
All it is, is a design for a front baffle, with no thoughts on the rest of a cabinet or crossover for the 'recommended' drivers.
Has he tested or done any measurements to see if this is a valid workable design ?
If your going to sell a baffle design, for certain drivers, WHY would you not also offer a cabinet and crossover design for sale as well ??
Hey buy this cart, then buy a pony to push it along later.

I think I’d like a resource for a build for a baffle that size with those drivers. It was initially going to be done as a TL design but that was scrapped but demensions on some level could still be the same. That videos still on his site. How thinking may be that it’s not terribly difficult for a certain level diy er to come up with a two way crossover for the known drivers and potential enclosure. Maybe I’m too new to be answering. A wuestion the answers already exist for
Not per se, just a bit inconsiderate since 'we' as a group (and especially folks like me that are in a time 'crunch') shouldn't have to go searching for stuff that the poster is interested in, i.e. at least a link should be part of the initial post on a given subject.GM- did I do something inappropriate?
Edit: So all you want is a back box design for the Purifi PTT6.5 (Purifi PTT6.5M04-NFA-01)? If so, I can't make out the dims........
Regardless, assuming published specs and a minor amount of series resistance (Rs) = 0.37 Qts':
T/S max flat alignment:
Vented net volume (Vb) (L) = 20*Vas*Qts'^3.3 = 9.774 L
(Ft^3 = (Vb)/~28.31685)
Vented box tuning (Fb) (Hz) = 0.42*Fs*Qts'^-0.96 = 60 Hz
F3 (Hz) = Fs*0.28*Qts'^-1.4 = 61.95 Hz
This is close enough to a Vb = Vas/13 L, Fb = (measured) Fs alignment for me to build it and 'critically' damp the 3" i.d. dia. x 10.91" long vent.

edit: forgot it's a MLTL, so vent is shortened to ~8.15" long.This is close enough to a Vb = Vas/13 L, Fb = (measured) Fs alignment for me to build it and 'critically' damp the 3" i.d. dia. x 10.91" long vent.
It’s more that I want to keep my designs in the hands of actual DIY enthusiasts, rather than a non-DIY audiophile taking a turn-key plan set and getting a local shop to build just to save money.Looks like he’s trying to monetise everything in his notebook, ideas and incomplete designs along the way.
The baffle is fully developed and not just an idea. I’ve used it successfully in a number of projects with test data and customer reviews backing it up. Any competent DIY enthusiasts should have no trouble getting world class sound.
