They appear to be outside measurements and the videos on YouTube of that cab lead me to believe they used ½"/12mm plywood.

I found this linked in a old Talkbass thread from 2010.
Its a little bit easier to read.

Good find Kevin

Thanks a lot. I guess that 370 plan combined with the rough drawing I posted earlier of the 360 should give me enough information.
Going to print that out and discuss it with a Schreiner friend of mine (strange that english only has the word carpenter for both jobs).

Although that plan says 3/4" wood.

There are a million folded horn designs that use two, shorter lengths instead of one longer one. Were people just not that into bass extension before?

You use two paths when you want maximum mouth area for the highest possible sensitivity, at the expense of low frequency extension. That's why I use dual paths in the DR tops, but not in subs. But the horn paths of the Acoustic are so short that it barely works as a horn at all. The DR200 horn is longer. Like I already said, by 1969 standards it was better than average. But so was a 19 inch color TV.

I realize how shitty the Acoustic 361's frequency response is on paper. The thing is though that this exact (extremely non-linear) response emphasises the most important ranges when it comes to electric bass and live gigging. Hence why Jaco kept using them well into the 80s even when better alternatives (on paper) were available.

Ultimately, I just don't want to have to depend on the sound engineer to know what he is doing, meaning my cabs alone would be sufficient on their own to fill the room while actively attenuating problematic frequency ranges (like the <80Hz and >1KHz, cause that's where the guitars sit).

I saw Jaco, on more than one occasion, through different rigs. He always sounded like Jaco, because his tone was in his fretless and his hands.

Perfect when the sound guy doesn't know what he's doing or doesn't care... or for venues without a dedicated sound tech. Although. it presents a potential PITA and detriment to overall sound and mix quality for a tech who knows and cares.

None the less, we all have our goals and ideas of how we want to achieve them. I'll be very interested to hear about how well this cab works out for you, if/when you get one assembled. Please keep us posted!

Sure, that has to be the priority but without sounding cocky, I'm already close to that point with my technique. Last gig I just went straight into the PA without any EQ and it sounded exactly how I wanted.
The 361s (fed by my 1976 Jazz chorus and a Crest CA6) is just the icing on the cake.
