Anyone have the Zaph 12 speaker project(seas L15+27tffc) archived?

[year98]

I bought an L15 driver a long time ago and kept it.
I've been wanting to make a speaker using this lately, but I can't find data.
I would be very grateful if someone could send me a copy of Zaph's page.
What I particularly want to know is about L15.
Infinite baffle response, box response, T/S parameters, and how many liters he used and what Hz he tuned.
If doesn't exist copied page, can anyone tell me just only these?

I spent the last 20-30 minutes trying to find anything online and offline and couldn't find anything. I even tried the Wayback Machine but it only goes to 2013 - the L15 project was initially produced in 2003 and moved to the archive section before 2010!

Thank you for your hard work.
I think the results will come out if I keep looking.

Well, I found something. Maybe. Found a datasheet for 'an' L15, but I'm not sure it's the same one. This appears to be from 2007. Using the parameters we could figure out a proper tuning (if this is the driver you have).

Crossover:

This is something I've already seen before.
Of course, crossover is similar to zaph's original and helps a lot.

I think I found a reference stating people used to use the knock down cabinets from Parts Express. Probably 0.25 ft^3 then? Not sure they went smaller than that. We would just need to figure out the tuning frequency to determine port size/length.

Edit: Not knock down, premade with clean baffles.

this seems to be the closest topic on Zaph’s site.

Gentlemen, at last I found the answer.
Someone grateful provided a copy.
Google the same title in diyaudio.
I'm grateful to everyone.

I'm glad Dave could hook you up! For the sake of posterity I've attached his zip file here as well. I don't see too many people using a 20 year old driver, but you never know!
