You are welcome to use tubes on your own boxes, should you wish to do so.
Each and every builder can decide for him/her self when building. I am personally biased positively towards slot ports, and think there are very good reasons to go that way, rather than using tubes.

that's good to know about the port and yeah I guess I ll skip the curve 😉
you are right about the thickness, the only reason I said 25mm is 1.5" (~37mm) is not that easily available but we can always go with gluing 2x 3/4 (2x19mm). can either adjust the depth accordingly or can make the front baffle stepping out about 8mm 🙂
thanks.

thanks.
hmmm, I can make the back panel removable and can add some extra pieces to adjust the port length maybe 🙂, we'll figure it out 😉
An update of the cabinet Tower XL AE drawing to be conform for the simulation model.
that's great Paul thank you.
usually how many prototype you guys build? just trying to figure things out since this is huge and needs a lot of wood and trying to keep it to minimum.

With a bit of luck, one prototype is enough. With a bit more luck, the prototype can be tweaked to the final design without too much work.
Theoretically a dome tweeter should work but in my experience they fall apart quickly when the going gets tough. Besides a cd sounds more dynamic and effortless imho. 🙂
I agree. I've never heard a dome go remotely close to matching a CD at SPL, especially in terms of distortion and especially longevity. Why have a throttle in a highly dynamic system like that. It's like buying a Koenigsegg and attaching a box trailer.
Looking at the port it seems the corner/curve at the opening of the port inside the box should be considered as part of the port. I guess the effecive/acoustic length of the port would be more than shown in the drawing.
The corner inside the box is taken into account for the effective port length calculation. Added 19mm for upper port panel thickness and half the distance of the internal port mouth to the cabinet back panel, Kaffimanns proposal. Not done for short port option of course.
hmm, I haven't heard a CD that I would quite like, maybe they were bad designs but in my experience they don't sound as detailed as a good tweeter. I m not sure how to word it but to me CDs also sound a bit "bolder" than tweeters but again mybe I haven't heard a good one. In general I m not sure how other feels about CDs. from my understanding a good CD can be pretty expensive.
also a sensitive tweeter shouldn't have any problems keeping up with the SPL.
