About to pull the trigger on a pair of the LASE drivers and get building.
From what I gathered, the LASE driver sims well for a budget driver but is currently untested? I don't think there's anything in that same cost bracket.
I have DATS v3 and would be willing to measure and post up findings. Just kind of concerned about getting unusable drivers.

Art,
The driver is ordered. When it arrives I'll measure it to see real world t/s specs as they seem questionable.
It's going to take a bit to build out the cabinet unfortunately. We did just print off some syntripp lenses to match. Can't wait to hear the combo in our normal party space!

Hopefully the photo attached properly. This is a fresh Lase 18lf-3600 measured in free air with spacers under the magnet to allow the vents to be open. Leads on the Dats unit were calibrated before testing. Seems to be a lot of driver for the money, and the specs look to be close to what the manufacturer has listed for the NEW! model.

I don't recall any shared solid models in this thread.

The 3d printed one really makes me wish we have a printer with that large of a bed as currently it's just big enough for syntripp lenses. Assuming the post linked in the OG post has the link to the correct plans (post 487) I'll make a quick model off those and host them as it might help other builders out. I do plan on designing templates for panels that have more going on, as this just makes building a fleet so much easier, and I'll post them also.
If the bed if your 3d printer is not big enough for what you want to fabricate, just print it in smaller pieces that you can glue with epoxy after, you can add dado like joints or some kind of holes on one piece and some pins on the other so it will mate perfectly and with epoxy or some other glue that the community recommends will make your lens or part indestructible!!
Unless it fall from a 15 feet scaldfold 🤪

I was referring to the 3d printed keystone mentioned above, it's beautiful but printing on a small frame printer would be literal hell.
I've modeled up all of the main panels and just need to draw in the bracing. This is all done in fusion360 and I'll post a shared link soon.
What's the take on "speed holes" in the bracing? Are most people building with them? The braces themselves are rather small in area as designed (which is likely fine for 3/4 ply) so I'm unsure if it serves any purpose to add them.

Speetpeet's construction, measured response, the holes in the braces and their placement and shape are all quite different than any other Keystone sub builds done according to my plans.
The experiments I did with a plate covering a portion of the driver throat made the response worse than without.
I don't know what BP1Fanatic means by "I gotchu guy!", but the photos in post # 1671 are not representative of the Keystone Sub as I designed it.

The term is "lightening holes", they take longer to make
If you look at the plans, you will see I did not use any, nor do I recommend them in the Keystone as designed.

I modeled it up. Should be pretty spot on from the cutsheet.
