Here's a good cabinet design PDF I pulled off a celestion blog. Interesting stuff but don't think it applies to the F12 since it's a hybrid. There's a ton of science involved that's beyond me lol

Maybe this is why there's a port in the Celestion drawings...?
I'm pretty sure the size and length of the port tunes the bass frequency response of the box.
My understanding of open vs. closed back was also in how the lower frequencies were heard...?
I think a sealed ported cab is going to have a tighter bass response with a tuned low frequency response where an open back sounds reflect off whatever is behind the cab with a looser bass response.
I'm not sure why ports would damage a guitar speaker... here is a ported 2x12 guitar cab
Guitar speakers are not recommended for use in ported cabinets (as the increase in cone excursion below the tuning frequency can cause the thin paper edge of the cone to tear).
This statement by Celestion seems quite strange to me as I have two 112 Ported Mesa Widebody cabs one with a stock made-for-mesa C90 speaker and the other with V30 that I put in after purchase but which the cab could be purchased with stock
Yeah that does not make sense.
Perhaps it meant 'an improperly-tuned cab'?
You're probably right. Maybe some guitar speakers are more fragile than others. Idk but zilla and mesa both offer them.
MDF is about 40% heavier than birch ply of the same thickness. It also does not handle moisture exposure well at all. Definitely not my first choice for a cab that will be moved around a lot.
I was also gonna not recommend MDF, but couldn't recall the exact reasons, cuz I don't work with it enough. But putting dollar signs next to it and Birch, implies trying save, what, $40 on a sheet? It's just not worth trying to be that money-conscious when we're talking about, what, half your sound? Of arguably the best-sounding modelers on the market... Kinda stepping over a dollar to pick up a nickel. Plus, you'd already be realizing some savings by building them yourself, depending of course on the value of your own time. And then, some of us don't care about that at all, due to the enjoyment of building them yourself.
Aside from the price, I think his point/question is interesting - does the IR captures the wood type of the cabinet? I always use birch ply or solid pine on cabinets, because it apparently sounds better. I did birch ply because celestion said to. Its possible the resonance of the wood is factored into the speaker (guessing).
Not just the wood type, but the shape of the box, via its internal reflections, affects the sound produced. It is also reflected in the impedance curve - that's what all the little lifts and bumps are in the more accurate impedance curves we got a few firmwares back....
Guess you are going to find outSo I just ordered one of these. Used so the price wasn't too bad. I am curious how the F12 does in a Thiel style cab.
How are you going to wire them?
I'm going to have to look up some info online and learn how, never done this before. In parallel and mono I imagine
