I think you'll be glad you switched to active when you get done. I was running a 3 way+ sub through a DCX2496 before I got my line arrays (my arrays are exactly like Kevin's). If set up right, you can play quite loud, quite cleanly with an active system.
Helped a buddy set up some 3.1 ways with a MINIDSP for his theater room, and it is much more powerful than the DCX. Once you get the line level switches set correctly (he failed to read the manual- and didn't tell me as much) it is dead simple to set up.
IDK what your plan is- or what you have now, but be careful about crossing those ribbons too low. As you likely know, steep slopes help with this. Also, ribbons DO NOT like turn on/ off thumps. Shouldn't happen with a DC board in there, but if the power goes out...a protection cap on the tweeter would be a wise choice. Not to cross over, but just to protect a bit.

I have Linus Arrays
Kevin and I built our Linus Arrays at the same time. That is why I am buying these Peavey Versarray tweeters. I want to build new Line Arrays, using TRUE ribbons, not planars, and find a better mid-bass driver. Technology should have given us some better drivers, but I'm beginning to wonder. The more I look the more I like the MCM drivers. They do have a cast version now, but the price has gone up as well. I'll take all the help I can get in setting up the MINIDSP module. I did get the measurement mic, and downloaded REW, so I can take the speaker outside, and set it up correctly and then make adjustments for in-room. If I like it, I may replace all my crossovers in my listening system, both the Solid State systems and the analog system. Gotta think sending only the information that is going to be reproduced to one channel of a Phase Linear to be amplified and sent to the speaker driver MUST beat the crap out of sending all the information to the amp. and then having the passive crossover let only the sloped information pass through to the driver. As I understand it, there are multiple EQ's and filters, plus the ability to go from 6db to 48db slopes on the driver itself. Gotta have the alility to do some major stuff.. I can't wait to finally hear my Lambda Unity horn system. I've never had a passive crossover which was RIGH for them. We did have an active EQ making them sound good, but I'll bet done right, they will blow your mind. The Peavey ribbons are basically Fountek NEO CD2.0 but for 79 bucks each instead of 50 bucks each..And yes, I put a 20 mF cap in series just for testing, and it will stay attached to the positive pole of the tweeter,regardless...

There's a shit ton to talk/ think about with what you are planning. I'm going to be busy tonight, but would love to discuss later.
You've read Dr. Griffin's white paper? If not, do it, and do it again.
The cast mcm tests pretty well- zaphaudio.com I think there's a truncated frame version that would bring acoustic centers closer shortening integration distance/ minimizing comb filtering.
The mini dsp is very powerful, and pretty intuitive. This will be very helpful in getting the arrays to sound right. Good quasi-anechoic measurements may be a bitch. Global parametric EQ, shelving filters. Each channel has them as well, etc. Easy to save multiple profiles allowing you to switch back and forth when it comes time to voice things. The switches on the board I referred to get matched to the input sensitivity of your amps. Which mini did you get?
Not sure I follow your price comparison. Oh wait, you meant the planars are $50. I forgot they went up so much when neo jumped.

They can, but you're talking bux. Sounds like Sutton is on the way though.
I've heard Dr. Griffin's newer ones (his personal- the linus were a prototype, oddly enough.) and they do in fact sound better. His have active XO using the DEQX, and nicer drivers, though I forget which. True ribbons, and ??? midwoofs.
Jim Griffin is a great guy, BTW. Smart, humble, and generous. Is that the right order? hmmmm.
The Linus are no slouches mind you.

And knowing Sutton HE WILL FIGURE IT OUT !!!! I really don't see me spending any more money on mine.... My next move on speakers will be moving the Linus to the rear channel and putting K-horns on the front.... Zach !!!! I know what I've been meaning to ask you.. Did you ever hook a 700 to those things ????? I remember you talking about it just don't remember if ya did it ? Ya know whats really odd is the fact that our two pair of speakers were in the same room together many years ago in Georgia !!!! And we sit here today talking about them... HA ! And yes... What I remember about Griffith he was top notch !!! He went out of his way to help Sutton when we were building these !!!
Sutton has gone straight to the source on this, and is getting (of course) good advice from Jim directly. I wound still highly recommend that S go active if possible, since XO development and ROOM CORRECTION are so easy with the mini. It's not a miracle machine, but...designing passive for lines will be an iterative process for sure. Not going to get it "right" the first time. IOW, PITA.
I'm ashamed to admit that I have not. I wanted to listen in stock form for a while to compare before and after WOPL sound, and one day when I got home from work, the Ole lady told me a channel was out. Fearing the worst, and expecting company, I pulled out that system and put the 3300II, and 300II back in and set the 700B aside. Well, it was just a blown fuse- must have latched up. It's in the kitchen, so lacking massive power isn't really a big deal.
It runs now, but I still haven't put in the WO board, cause I'm stupid. I did, however, close up the Nikko Alpha II I am restoring and put the 700b on the bench yesterday morning. My brain wasn't working due to lack of sleep so that's where it sits for the moment...soon. May still be a bit, since I'm going to try to pick up a Pinbot pinball machine this weekend (needing repair- it's for my wife primarily, so 1st priority) and have a bunch of other stuff going on, but it's on deck! I think I've had this thing for 3 years now- what a doofus. Oh well, it's a hobby, right?
For now, still on the outlaw 7100, but it's no slouch, and with the high sensitivity, it'll still run folks out of the room, yet remain poised. They're also crossed to subs at 80Hz, so that helps.
Your speakers came from Jim?
Zach
p.s., I believe you may have lost your mind. K-horns with array surrounds? You crazy, dude.

Yes I do !!!! Zach... Sutton and I built the two pair we have but I'm pretty sure the ones you have are the ones he had Down in Atlanta when Sutton and I took mine down there to that speaker building competition.... That's been a long time ago ! And I still say you aint heard your speakers till you get that 700b driving them !!! I know I hadn't !!!! So you think that K-horns on the front... Array's on the rear with 700 per pair and Paradigm studio 11's for the center channel with a 400 on them WOULDN'T WORK ?????? LOL !!!!! MAN... I had my heart set on that ....
