The kappa pro 15a is a PA cabinet 15, not a sub. It's made to be run ported with a 2" compression driver over it.
Yes, ss15 means 'SingleSheet15'
yes the ss15 can be stacked or run side by side. The more in a stack, the lower and louder it plays.
One of the ways I've used mine is to put a sub and top over it every 50 feet in front of an audience. This kinda sounds like what you are interested in doing?

Thanks again Jim;
Ok so I looked at the Eminence Catalog again and never noticed thare Compatibility Charts before. I see it now. Anyone what a good deal no some Kappa Pro-15As?
I was thinking along the lines of one stack every 100 feet times four, but what do I know? This is just what one sound company did with some short horns for one of our shows. Andy
Jim; I just finished reading thru the hole single sheet thred. Wow you may have found a diamond in the ruff. Vary nice. So now its between the SS15 and its big brother. Is bigger realy better? Andy
bigger is better if you 'really' need lower, and you have a reasonable way to move them. I was at the football stadium a couple days ago where I installed 4 of the big cabinet on TOP of the press box. I was across the field on the visitors side and could feel the bass. Now, how many subs can be 30' in the air and make bass? If you read through the entire big cabinet thread, you'll see that the big cabinet was my very first attempt at a tapped horn, I barely knew what I was doing.... but with help from several on this thread it was successful.
Big cabinet is install, ss15 is mobile. I think for your needs the ss15 is the cabinet. You need a good horn loaded top cabinet to keep up with it, and there are a few options on that.

Jim; I will read thru the hole big box thred next. Do you have a post on the tops you are using? Andy
I don't really have a thread on any of my tops. They are just dime-a-dozen kind of design... They key on these is to find the right driver to make a horn/ported cabinet work. Once you find the driver, you have to play with hornresp for awhile to get a nice flat response in 4pi. (tops don't sit on the ground, so response curves tested that way are bogus in my mind)
Here's the best pic to show how my tops are built. The horn 'plates' are 13" long, and 45 degree angles on each end. It was designed to use partsexpress 15x22 metal speaker grills. I just bolt a 12" dayton waveguide to the metal grill and use a 16ohm selenium crossed at 2k. It uses an eminence beta 12a-2, and ports are tuned to 95hz. (sorry, not a fan of the cheap eminence compression driver....)
If you don't choose to use your kappa 15's in a typical 15" pa cabinet, and want more details, I'll dig up my cut sheet and some hornresp data on the tops. If you want to build an all eminence top with the kappa -- http://www.parts-express.com/pdf/290-422c.pdf Use the small vented box. Eminence HF option looks to be the 1" 2005 driver with the 395 horn and cross at 1.5k.

Jim; If I use the 15 inch tapped horns for subs would you recomend 15" or 12" for woofers? I am hoping to stay with the PSD 300-8 and APT200 for the HF drivers. Andy
yes, the 2" psd3006-8 is a good driver. The goldwood 450 is a good horn to mate up with it. Goldwood GM-450PB 2" High Frequency Horn | Parts-Express.com
You can cross at 1k on the psd, possibly lower.
Isn't anyone gonna suggest the LabHorn??? This baby may be too loud and too big. A stack of 6 weighs 1500 lbs and it's 32 Hz bark has drawn complaints
from 7 miles away. It is the horn that the LAB12 was created for.
These things have worked the pro-sound circuit for years ...

Jim;
We got the Eminence horns TI2000 about the same exept it has a 60X40 dispersion pattern. You dont Like the APT200 or do I even need them? Andy
60x40 pattern at your proposed 100' spacing... means you need these a good distance away from your audience. You said you only needed up to 15khz, and the psd can do that without the apt200. However, it sounds like you have a design picked out, and ready to run with it. Post pics and measurements -- I'm sure there will be many interested in the outcome.
Don; I am thinking of that one two but it is a lot harder to make. I would still like to see a straght horn. If Eminence made the LAB12 for the LAB Horn,then what did thay make the LAB15 for? I still have not seen a design for that one let. Andy
Jim; Thats just it the desigh has not been picked out! I am picking this project up that was started by someone else that is no longer with the company. He speked out speakers and I am trying to figer out what to do with them. The 1st thing I learned was that making reg ported/vented sub boxs was not woth it. We would have been better off going out and getting some used ones. I think it is a better use of our resorses to make horn subs. The subs the owner bought already are now for sale.
I need to come up with a good sub and then work on the tops and thats why I asked for your input. Please dont give up on me! Andy
nah, I'd never quit on someone who needs answers if I have someway of helping... It was just looking like you had a specific direction to go, and I didn't want to step on toes by saying that was not what I would do...
Your 15+2 kappa-psd top is very reasonable, and yea the apt200 'could' give you a little bit of extra high end. At the distance you'll have to have them away from your audience at 100' spacing because of your 60x40 horn, well I don't think your audience will hear them much. My best guess is that you'd be happier with the goldwood horn and it's wider pattern. BTW, you have your crossover sorted out for the top?
Selling the omega 18's is your absolute best bet on the subs, and I'm glad to see they are already for sale. There really isn't a good way to get the bass you need, at the distance you need with those. (my opinion)
My absolute best bet for you is a pair of the single sheet subs with 3015lf's under each of your kappa-psd tops. That would give you a nice modular, lightweight system with all the bass you need, even at 100' spacing. (labsubs really don't lend themselves well to sitting under tops spread out across a field, they really should be clustered)

Yes, much harder to make, and must be used in a stack of 4 minimum. The LAB15 was built as a step-up for those who would use LAB12s in a sealed box.
No matter how you go, you must have a truck to transport. You'll also need to address the electrical power required (generator, 100 amp service, etc).
Jim's big box is efficient, and while heavy (150 lbs), nothing a truck and a crew of roadies can't handle. I think you're in for a truck load in any case.
What's your most critical problem?
~Don
Hi Jim,
Since the big box is twice as efficient, wouldn't the truck space be about the same?
Hi guys,
The LAB15 seems to be build very solidly, and modells well in all kinds of enclosures. It may not be the best for PA use, but I would not count it out, it looks quite versatile. I really like it in a dual configuration in a tapped horn, or as a small (down to 2ft^3) BR. The only drawback is the high price, I just happened to luck out on the Guitar Center sale 🙂, so now I've got to find the time to test them.
The 3015LF is much more cost-effective if you can live with the enclosure size.
Regards,

Big box is more efficient down low, 102db@40hz, vs 98.5@40hz for the ss15. HOWEVER, the ss15 is louder from 50hz on up vs the big box watt for watt. The big box is 2.5 times the volume vs the ss15, and three times the weight. In pairs, the ss15 gets flat to 40. Big box is limited to 50volts input, ss15 to 63volts.
SO... a pair of ss15 will absolutely SMOKE a single big box. The thing the big box does that the ss15 can't even consider, is it digs below 40hz....
I still love the big box for some permanent installs, but the more of the ss15 I build, the happier I am with it as an overall good design.

Jim, I'm so glad to see you giving the limits and the levels in volts. Thanks so much for that. 
And thanks for helping out here, I think the pryomusicals are on a good path, now.

Jim; Thanks for sticking in there 🙂.
Any idea on the spreed of your sub boxes I know you say thay are directional but how wide do thay go?
Andy
Sorry I lost you thare, please describe.
The 100' spacing is not set in stone, just off the top of my head. I need to be within 50 feet from the audience, as far as I know the speakers will determan the spacing and distance from the audience. I was figuring on four sets but will do more if I have to in order to keep closer to the audience.

Thinking bi amp or tri amp an doing the crossing with DSP.
