Thanks for the info. Do you know what ports are used in the first design? Size, length, whom purchased from? Is this a 12" or 15" woofer? Maybe a link to what ever article these came from?
Yep, did that when djk said Crites kit. I was looking for ported slim/tall cabinet for 15", since the Altec Model 19 was 15".
Yes, the 19 was a 15" two way.
I would look at the 15" SEOS horn (about $35), plus a nice 15.
Better yet might be a dual 12 plus a 1" horn (SEOS, Faital, etc).
Over the years I have built many such dual 12 cabinets, using all-pass delay networks on the 12's to align then in time with the horn HF section. I used 12" Eminence woofers that were around 94dB and could do 30hz in a reasonable sized box and have a sensitivity of 100dB/2.83V/1M (in pairs).

That Faital horn looks darn sexy. I am still wondering how much it differs from the 18s XT1464 sonically.

in post #68 (pg 7 of this thread) LineSource posted a crossover schematic for the Faital 2 way.
I have a set of Faital 15PR400-8 woofers and am investigating a design like the one he mentions.
Anyone built this?
Can anyone provide any other details on the design (cabinet volume and tuning, measurements, who designed this, etc.) or point me where to find them? Thanks

I've seen a few people mention Wayne Parham's Pi speakers, but no one has followed up with their thoughts. Wouldn't they be a valid alternative, or are they too bass shy?
For a 15" driver, the 4 Pi is fairly thin at 18".

Not with these drivers, but numerous folks have built M19 replicas with Altec and/or GPA components: MODEL 19
Official Altec cab plans, tuning is around 35 Hz IIRC:

edit: I calculated the M19’s net Vb = ~8.82 ft^3 gross.
