"brides might freak out at seeing a double 18".

Flexibility and portability rules.

You can cluster the subs in the middle, if you want, or they make very stable speaker stands.  Also, there will be times where space will only allow 2 subs stacked, with 1 top on a shorter pole; run in mono.  It will kick!

Also, I'm afraid brides might freak out at seeing a double 18.

Put a white tablecloth over it, let her decide how to decorate it. Kids candies and snacks, photos, etc.

As long as your system is neat and clean and wires aren't all over the place exposed they aren't going to say anything.  Look at how many DJs set their lighting up in the air with all the cables just hanging and they end up in wedding pictures yet they don't seem to complain.  I've never had an issue with a bride complaining about my gear and I send EVERY couple a pic of my setup when I send them a quote so they will know what they are getting ahead of time.

Having started my company as a wedding/school dance DJ (in the same position as you) -- there's something to be said for the flexibility of the SRX-812P/SRX818P combination. However, if I was in your spot and looking to purchase a PA, I would actually get 4 SRX-812Ps and 2 SRX818Ps to start with. Since, as you know, at weddings the people who are looking to really enjoy the music (i.e. feel the bass) are going to be on the dance floor, that's the main spot where you need to have that low end coverage.

Not sure if they're going to want all of that stuff shaking off every few minutes. ;) But in all seriousness, brides can sometimes be as bad as corporate event planners in that they don't want to see "all of those boxes everywhere," and having a smaller sub that's easier to tuck under a table or in a corner is not a bad idea.

With two more SRX-812Ps, that makes a quick and easy ceremony or cocktail lounge system. Since the speakers have two inputs available, you can put the ceremony music feed into one input and the officiant's lavaliere microphone into the other, for example. Or, if you have a larger venue, you can use that second pair as delay speakers. (I started my business with a pair each of Mackie SRM450s, SRS1500 15" subs and SR1530 15" 3-way tops, and within three years I added 2 more pairs of 450s and a pair of SA1521s. And sold the 1530s after a year, when I realized that I just didn't need them enough to justify the expense. Part of these upgrades was to support having one or two other DJs freelancing for me, but mostly was to improve the flexibility and coverage of my setups. You can include the main pair of speakers in your basic package cost, and then have the second pair of SRX-812Ps be "Just $129.95 total more" or whatever you want.)

and then buy one or two pairs of the SRX828Ps for the school dances, and you'll have a ridiculously good sounding system!

Right now the budget won't allow the purchase of an extra pair of 812's, though I agree with what you said. I do a lot of ceremony and cocktail hours in rooms other than where the reception is so I like the idea.

If the quotes for the lighting rig come in less than expected I will do it.

What about the music you are playing though???
Do you get into old 60's stuff on a regular basis, or even 70's rock?
I'd want 15" bass cabs in that environment personally, preferably 4 x 15" speakers.
 Lent a system to someone last year which had proper 18" subs running up to 100hz.
All the 60's stuff was horrid. Luckily the cabs on top were 2x15 + horn (Beyma stuff) and I quickly took all the 60hz and above up to them. Much better,
Just my pennies worth and of course if it's generally modern stuff then would agree basically with your choice.  Have fun.

I forgot about this thread. Here's what I have so far:

2 - SRX812P
1 - SRX818SP
1 - SRX828SP

I run everything through a X32 and have it setup as LCR with the center mono channel feeding the subs. That gives me quick control over the sb levels. It also allows me to not send the mics to the subs which clears them up a bit.

I do have 2 more 812 speakers that I can rent when needed for delays or side fill. I plan on purchasing two more and at least one more 818 and 828 when budget allows.

One difference I do see in the balanced input impedance. PRX is 20k and SRX is 40k. I understand that higher is better as it won't affect the output voltage of the source as much, is that correct?


Don't worry about the input impedance.

Assuming a drive impedance (output impedance of previous device) of 150 ohms, and a target load of 10X, you can easily hook up more than 10 cabinets to each output without loading down the driving device.
