So what would the cusp look like? Like sharp angle?
and how to make that from the base level drawing?

I'll let you know when I get the info,
Thank you.
.
It looks like a sharp tall pick. Just make the two sides come together a little faster so it doesn't leave a parallel slot.

My goodness X, I would have thought your line of work kept you busy enough that you wouldn't have time for all this. Speaker #438 is it?

How do you like the driver overall?

Hi Cal,
I am quite busy with work and other things. I don't sleep much.

Close, speaker #427

I like how dynamic the FF105WK is - good bass extension and very snappy. The peak at 7.5k still needs to be dealt with. There is also a dip near 2.1k but that is less bothersome. It's a good start and I am glad I made a tapered TL kind of like the kind PMC uses for their monitors.

Hi BP1Fan,
Thanks! Did you see the video of the snappy bass? Change extension to .mov to watch in Quicktime.

My phone says the video is unsupported or corrupted.

Can't do it from phone as it needs to be renamed to have .mov extension. The .asc extension was tacked on to get past the 760kB max file limit. Have to do from desktop.

I think tomorrow I'm going to build some mock up boxes for my infinity 120.3 dvc 12 inch subs with 13mm of xmax so I'm interested to see how the foam core would handle the excursion. I'm planning on making a 1.5 cu ft box sealed with some internal foam bracing. I'll definitely post some pics as I build them tomorrow. No matter what ends up happening it'll be better than having them just playing just sitting on the ground with no baffle haha. Even still I get decent bass down to 40hz with no box or baffle lol.
