I am wondering it there are any folks that still are using the behemoth Electro Voice xi1183 out there (Xarray)

I have 6, and calling EV customer support isn't a huge help. Maybe cuz' they are old, but I feel like when I call I get someone reading off the same sheet of paper I just did and not really answering any questions on the legacy products.  I wish someone knew the box, and knew what was going on, but I guess it's in with the new now

Here are some questions:

1) It seems like the NL8 going INTO the box is a different wiring then the NL8 going OUT next to it. The white paper for the xi-1183/64 (and note mine are NOT the newer A version) says it's parallel inputs. Yet, as you read further on that same white paper, the block diagram looks as if the input uses +4/-4 off the NL8 to reach the 18" (this is a 3 way box) while the +3/-3 does nothing.  But it looks like the OUTS on the boxes NL8 is now +3/-3 to the next one and now it's 4th pair doing nothing, which means using a standard NL8 jumper you would lose the signal. Whats up? Does a jumper cable between boxes need pair 3 hot on one side, and pair 4 on hot the other from that same set of wires inside, that is, a crossover cable?

2) As mentioned I have 6.  I know in theory your not supposed to run 3 a side, side to side/tight, for the phase cancellations and all that phase stuff, but as a realist, is there any reason you can't? That is, I am sure people tight pack QRX boxes, SRX boxes, EAW 650 or 850 to get max SPL and wide coverage, so any reason if not "perfect" you shouldn't do it any more or less with this box then any other trap box? The seller I bought these from told me this will lose all the mids or something like that if I tried it with these

3) If above is true,  and 3 across is a no-no, would setting 2 side by side, with a 3rd one on top of that (triangle style), be an OK option?

3) Power for them.....the more the merrier? Can I run 3 boxes a side on one amp, per driver type ..that is, a "HIGH" amp runs 3 tweeters on it's left side, and then 3 tweeters on it's right amp side
then the next amp runs all the 12" mids (3 per side on the amp), and lastly the 3rd amp runs 3 of the 18" per side .

Just wondering as a triamp box how much juice folks hit these with to wake them up

Final note: when looking for subs to mate/play along with these, would one choose the QRX 218, the srx728s, or the "recommend" (at least at the time) XI-1191, which is a single 18 box. Or is it "who cares, it's a sub" kinda thing? 

thanks

Correction on my first question (opps) ...let's try again

HIGHS are pins +4/-4 off the NL8  (this is a 3 way box) and the out is also +4/-4 
MIDS are +3/-3 both in and out
But LOWS are +1/-1 in, but then are +2/-2 out....why??? Is this to somehow feed a sub? Would it not be a hassle to link the SAME boxes chained off each other?
And the pins +2/-2 ins, which hit no speaker part at all, go to the +1/-1 outs

Does a jumper cable between boxes need pair 1 wired hot off the amp on one side, and pair 2 on hot the other from that same set of wires inside, that is, a crossover cable?

The box looks like a install version of the Xarray Xn. Xarray is build with six amp channels in mind. A dual 18" sub which uses two channels, one for each driver. Then a dual 18" low(Xb) which uses two amp channels, one for each driver. Finally there is the Xf, dual 12"/ dual 2" top box which uses two amp channels for MF/HF. This way every component has a minimum impedance of 8ohms.
1 HF
2 MF
3 LF1
4 LF2
5 SUB2
6 SUB2
The Xn features a 18" low, 12" mid, 2" high. Its a combination of 1/2 Xb and 1/2 Xf. By crossing pins 1 to pins 2 and vice versa you avoid overloading the amp for LF1 while the amp for LF2 is falling asleep.

Your box is 16 ohms on HF and MF, but 8 ohms on LF. If you use them like EV meant (with pins crossed) you can put 4 boxes on 4 channels with a 4 ohm load on every channel. If you decide to solder the connectors straight you can connect three boxes to three channels with a 2.7 ohm load on the LF channel while MF and HF maintain a 5.3 ohm load.
If you stick with a maximum of three boxes there is no problem in resoldering the connectors. If you want to build a big system (like the AC/DC tour) i suggest you keep them like EV intended.

Please put a Xsub(or equivalent) below this box, it needs something with enough output.

OK, so I reopen King Tut's tomb, as this is a very old thread, but I still use my "3 per side" xi1183 rig. It may be big AND HEAVY, but when we just need to cover a crowd in the rain, snow, deal with a "guest engineer with the local band, and it's all about dat' bass" (read: idiot), etc it does the job and I don't need to sweat about if they get a scratch on them. Or, in simple terms, a B or C rig, but one that does a good job

That said, looking for it's "Soul mate" of a sub. You mention the X Line sub, which I love but is a little spendy for this outdoor 'take the abuse rig' , the gigs they go out on just wouln't offset what I think of as an "A" level sub

Anyone have these and ran the old 'match', the single 18" Xi 1191 sub? If so, any thought on using one of those with each 1183, or would you opt more for a QRX 218 sub? I think the QRX or old 'vintage' 1191 subs are in budget

So any .02 cents on the best sub between those?

This is indeed the install version of an Xn.

Andrew,
 I work with one of these rigs regularly, and they have QRX 218 below, but I feel they need more than the 4 they have to get some adequate low freq (sub) output. This company also has 3 of the 1183 per side, and have a custom fly bar so they can open up these boxes when flying wide enough to reduce the amount of comb filtering going on.  With all subs coupled, they power them with 1100w per cab, it's OK.  not enough to have serious impact, but some presence for their larger church type functions.
If you're only stacking this PA, you'll need something large to stack those 1183 on. Maybe get some lab subs, or Bassmaxx and use them for your impact.  Even the Danleys TH118 would be good, but the 115 is too tiny to be a good platform.
A LARGE sub for a platform is required, otherwise, you are placing tops on a standalone platform and subs in another area. That's a possibility.

Good luck.
