No sorry, going to be a couple days. Took them outside in the daylight and found a few cosmetic issues I want to fix. Don't want to do any cabinet work with the speaker in the boxes.
It's cold out but may try and get some work done on them today.
Got some work done on them today, one is glued up and will be ready tomorrow. The other I hope to glue up in the morning and have ready Thursday.

Well I know one thing, you are in for a treat! Going fully active with DSP and treating my room with absorption/diffusion are unquestionably the two largest upgrades I have ever made to my system. Do both of those things and you will surely ascend to a higher plane of audio existence, haha.
My initial reaction is to say go active first, simply because it is such a powerful tool. You really can make your system sound exactly the way you want it to. You will have control over frequency response and phase in ways you never imagined possible. It truly puts you in the drivers' seat of your system. It also opens up a new world of upgrades and DIY tinkering. You can essentially swap individual speaker components at will, using the DSP to knit everything together. None of this is even remotely possible with passive components.
However, I think you actually have the right idea with doing panels first. There are two reasons for this. First, it is an immediate and very noticeable upgrade. Your system will sound much better as soon as you hang the panels, and you will gain the added enjoyment right away. Setting up a DSP crossover takes time. These systems are powerful and have impressive capability, but they are only as good as the person programming them. It took me well over a year just to figure out how to set up crossovers and properly EQ a system. Don't get me wrong, I had it up and running and sounding pretty good in a day or two, or so I thought. To really get it dialed in, you will have some learning to do. I am only now beginning to learn about how crossovers effect phase response, and some strategies to address this (see Subconscious auditory effects..... ). Additionally, having a well-treated room will help you make better measurements of your system's response, which is a critical part of optimizing a DSP crossover.
So, if I were you, I'd do some sound panels first. Do a mix of absorption and diffusion if you can, but do absorption for sure. Try to cover as much surface area as you can stand. One or two panels will probably not get the results you are looking for. Try behind the speakers, side wall first reflection points and if possible, ceiling. You will reduce the reverb time of your room and increase the proportion of direct sound. This will be a very noticeable improvement. Then, after you have enjoyed that for a while, take the leap and go active/DSP. You'll have a nice-sounding, low-reverb room in which to start measuring and tweaking.
Excellent info, thanks! I'm about to finish a pair of exodus anarchy subs, next week I think I will try building some sound panels.
I already have the fabric just need some wood panels and roxul. May build some diffusers later, make it a long term project. Not sure I have the patients to do it all at once.
May have a temporary idea for active, have a fancy clarion active xover from car audio days. ( 12 volt) I've heard computer power supplies can be used to put out 12 volts. Might work till I get around to buying a home unit. Thanks again!

I have run these speakers in a number of configurations. At first, they were stock La Scalas with AL-3 crossovers. The only non-stock thing about them was that I removed the tweeter from the enclosure in order to time align it. I then ran this same configuration for a while with the K-400 horn replaced with the ZXPC horn (using stock K-55 with a 1"-2" adapter).
The real revelation, however, was going to a 2" exit driver (B&C De-75-TN) and a fully active DSP crossover. The performance gains are off the charts. I would never consider going back to a passive crossover at this point.
I have been thinking about going active for awhile. I liked going to a 2 inch horn, made a big difference. Running my horns straight off the chorus II xovers right now.
Can't decide if should go active for my next upgrade or do sound panels. I leaning towards sound panels first. Any suggestions on which to do first? Thanks!

Have you run your horn's / speakers passive?

In the end I had to cut, sand, paint and glue over 1000 individual blocks (16x16 per panel, 4 panels). I probably have somewhere north of 60 hours in this in total, but I think it turned out great. I was going for a land/sea or ground/sky sort of theme with the colors. I think it looks great. Definitely improved clarity and imaging of the system as well.
Thought about doing some diffusers a couple years. Looked thur the plans and decided I didn't have patients, more complicated than people realize. Great job, looks good!
I am using the same zxpc horns on my chorus II, 3 way. I found it be a nice inexpensive upgrade.

I agree with Mike, @MookieStl, and Carl, @CECAA850, wait 24 hours.
Ok looks like tomorrow night before I get to fire them up. Thanks! Need to build a base/riser and a small grill for the mouth opening anyway.

Absolutely.
At some point today I am going to glue on the final side panels. How much dry/cure time is required before I can run them. Should I let them sit over night before I fire them up? Thanks!

That is what I need for my MEHs. I wish I could get a flatpack still or some plans... I know where I can get some CNC work done if I had the plans.

Sorry just realized you were talking about a different sub. Still if you decide to build the exodus these suggestion may help!
There are plans on my thread about this sub, (exodus anarchy subwoofer question) these are complete. If you do a search there some on the net that are not compete. They don't have all the measurements for the baffle boards.
Easy and fun to build, you can opt to cut an excess door for speaker or not. Since mine are veneered I choose not to, if speaker goes bad I will cut/ build one. I also decide not to use a terminal block, building a base and speaker wire will simple run out the bottom.

Please post a picture of your chorus also. What mid driver are you using?
I have k55v soldered lug that I plan to try in mine with treaded (k-61)? Horns. Just haven’t gotten around to it. Also I’m not 100% sure I can use the chorus xovers without making changes.
My chorus are nothing special, just have a wire coming out to the top of tweeter going to the zxpc horn on top of speaker. The zxpc is not in a box of any type sits on a towel on top of the speakers. I did built a box for it but never used it.
Built a chorus type center channel, chorus Ii xover, k 61 mid , k 79 tweeter and kappa c woofer. Was running an academy center, nice speaker but the chorus center was much better.
When I started using the zxpc horns I took out the k 61, and k 79 from tbe center and replaced with a zxpc horn and de 10 tweeter. Center is presently not being used and stored but I will try to get a pic of it up by the weekend.
This was my first 2 inch horn and I love it, don't see going back to a 1 inch. The first thing I notice was the vocals, voices sound like people are right in the room with you. Piano's sound amazing.
I have an f20 that is going up front that will also serve as a TV stand. The 2 exodus subs will go in back to supplement and fill in the rear. Haven't heard the f 20 yet, should be interesting when I get it all set up.
Presently using 4 revel c30 for side / rear surrounds. Nice speakers and they match well with my chorus but I thinking down the road I would like to built some surrounds with k510 horns. Maybe, will see.
Forgot I am using a clarion 5.25 inch speaker on the zxpc horns. Tried ev dh1a and selenium d408 ti and liked the clarion best so I stuck with it.

First I’ve heard of these. Looking to add a subwoofer to my 2ch stereo setup with Chorus 2 as mains. Would these be a good match? Are these great with music or mainly for movies?
My first experience with these but I will be running them with chorus II mains. However I am running the chorus II's with with 17 by 10 zxpc mid wired Into a stock xover. ( rebuilt with a crites kit) The zxpc horn sits on top of chorus speakers, I love it. Wanted to try a 2 inch horn and I liked it so much I haven't changed it back. May be a few days before I finish but I will give a review when there up and running. Work.
Also have bob crites tweeter diaphragm's installed.

If you need to clean up the extra squish out on the exterior panels, don't touch it for about an hour or so. Prior to that it's really messy and gets every where. After that it gets so hard it's really difficult to remove. There's about a 20 or 30 minute window where it's easy to deal with. Heat and humidity will effect when the perfect time is to clean it off the box.
Thanks for suggestions on clean up! I used a slightly damp cloth right after clamping, it cleaned up but did smear and was messy.
Didn't get anything done today, when I get back to it I will try your suggestions. Thanks.

Too late but thanks for the warning, already got it on my hands. Good stuff but can get a little messy, latex gloves for sure next time.
Didn't get much done today looks like Monday before they will be finished..

Here is the last set I built for my son to give you an idea of a finished veneer look with grills.
They look nice, hard to tell from pic is that walnut? I plan on doing grills but only on the small front opening.
Speakers arrived today! Shipped Wednesday and there here already, 2 days. Should have both boxes done by Sunday or Monday at the latest. Can't wait to here what sound like.

Or pl the horn path, set the last panel on then clamp the outside and put weights on the inside.
I think this will work for me since I don't want screws thur the veneer. Pl premium is fairly new to me will it hold the panel on without screws? I laid a yardstick across the box and baffles and everything is nice and flat no open spaces.

Ok so just pl premium? Worried about a leak I can't get at, how did you guys secure final panel?

Did I miss this? What driver or you planning to use?
I order 2 from DIY audio, these where manufacturers by lik Mike with same specs as orginal.
I am thinking about using double sided stick tape on inside piece's to help insure a good seal. Either full 1/2 stripe or 1/8 stripe on each end to form a channel for pl premium. ( may push out tape? ) Thoughts, thanks!

As far as wattage goes, that's plenty.
Ok I was wrong, I do have a kenwood km 208 but it does not have the sub sonic filter. The one I was thinking of is a Yamaha ax592 integrated amp does a 100 watts per channel and has a 20hz sub sonic filter. Haven't use it in a while so I'll have to test it out this weekend.

What amp will you be driving these with?
I have a 100 watt per kenwood with a 20hz filter. Bought it off craigslist for 20 bucks, if it doesn't work out I will buy something more appropriate.

I understand the thinking that says, “what’s the harm, it might help, and now’s the time to do it.” One flaw in that theory is that once sealed in place, it cannot be easily removed. If the liner were to come loose, it could obstruct the path. The designer of the sub said it isn’t needed, which was good enough for me.
Good enough for me too, just wanted to get it right the first time. Just order 2 subs for the boxes, hopefully next weekend I will have them up and running.
