Does anyone have an estimate build time to complete 4 Dr 250's, I understand that it depends on the tools you have and the level experience you have. I have a table saw and most power tools available. and my wood working skills are good. I also know that the use of jigs could also help. I've only have 2 t-48's and 1 t39 under my belt so far as BFM designs go.
I had planned on getting these done months ago but got sent out of town for work. Now that I'm back our band is starting to pick up and i need to get these done. we've been playing some regular outdoor shows and the carvin tops we have been using can't keep up with the 2 t48s.

Hi I would say you could build 4 in about 40 hours but it depends on what finish you want.

Uh no. Unless you're completely jigged up and have some experience.

I've done lots of DR's. And have the jigs. I figure 16-20hrs start to finish. That's finished, done nothing left to do. Maybe the new ones are faster, but I doubt it.

The DR's are very intimidating to me...but I've only built six easy boxes.

I can only recall seeing your PVC pipe cutting jig, and I know you would have jigs for cutting piezos. Which other jigs would you use for a DR?

Assembly jigs for the horn throats and baffle throat assembly. Plus I built them a little differently than the actual plans. It was a quicker method that burned a lot of plywood. All pretty much invalidated now by the new design.

keep in mind Leland's understating a bit

Sorry I did only mean the woodwork bit and I do have a well stocked shop. Handles, corners, painting, etc just runs away with time.

I do like the new design. Looks easier for a newb like me.

4 x DR200 took me around 120 hours. That's everything from the first trip to the store for wood all the way to a cab ready to stick on a pole at a gig. It includes jig construction time.

YMMV depending on the level of fit and finish you want. I'm a bit picky about sanding, filling, painting, etc.
