Members derrick Posted February 9, 2010 Members Share Posted February 9, 2010 hi guys, i'm thinkig of going smaller and lighter because i'm getting old(51) i wanted to know how many people would i be able to cover outside. i want to get four peavey impulse 1012s top boxes,& power them with qsc3402&3002 power amps. i have four ls700p subs. we do sound for blues and rock, and funk bands.

Members RoadRanger Posted February 9, 2010 Members Share Posted February 9, 2010 A pair of Impulse 1012's bi-amp'd, properly powered and processed can cover 300 outdoors at rock concert level. I'd guess them subs wouldn't keep up at all - even with only one pair of 1012's. I'd want four double 18's on an iTech 8000 - I've heard that overpowerd by a pair of 1x12+1.4" exit horn cabs outdoors . The outdoors really sucks up the low end.

Members monthlymixcd Posted February 9, 2010 Members Share Posted February 9, 2010 ...assuming the wind is 15kph or less and not coming from the NW. The Impulse 1012s are nice cabs. Not sure if I'd give them that much credit RR... but they are nice. Link to comment Share on other sites More sharing options...

Members RoadRanger Posted February 9, 2010 Members Share Posted February 9, 2010 127db continuous each so a pair is almost 105db at 60 feet. Say the stage is 20 feet wide then 20 x 60 = 1200 square feet. 4 square feet pp = 300 people. With the back of the audience area fanning out to 80 feet you get 10 square feet pp. At 100' you're under 100db but I'd still call it "covered" at fair volumes. All depends on how loud they really need to be? The tops would certainly blow away those four ls700p subs . Link to comment Share on other sites More sharing options...
Members agedhorse Posted February 9, 2010 Members Share Posted February 9, 2010 Now factor in dynamic range and your average power goes down in a hurry. I also am not convinced you will really get 127dB SPL for very long. Just a gut feeling, haven't looked at the real numbers. Link to comment Share on other sites More sharing options...

I also am not convinced you will really get 127dB SPL for very long. Just a gut feeling, haven't looked at the real numbers.I'd think the proper subs would bring the slow weighted C up quite a bit? We haven't even hit on his plans to run two per side for more SPL. I'd think that would be a bad idea with these 90 degree cabs, whatcha think? I might get a chance to open my pair up this summer, I'd probably borrow an iTech4000 to power them in biamp'd mono. I know a guy that uses them for his biamp'd monitors and he owes me a favor .

Members agedhorse Posted February 10, 2010 Members Share Posted February 10, 2010 Do you think doubling up the boxes would double the number of people covered? Or increase the SPL by ~5-6dB over the same area. Link to comment Share on other sites More sharing options...
Members derrick Posted February 10, 2010 Author Members Share Posted February 10, 2010 i guess from what i've read so far, 4 peavey impulse 1012s powered properly could do maybe up to 500 people outside. seems like RR thinks 4 ls700ps subs would not be enough anymore opinions. they would be appreciated.

Members agedhorse Posted February 10, 2010 Members Share Posted February 10, 2010 Depends on how loud you need to be. 4 Impulses may not be adequate. Link to comment Share on other sites More sharing options...
Members derrick Posted February 10, 2010 Author Members Share Posted February 10, 2010 as i said before we provide sound for blues, rock, and reggae/funk bands and yes some of the bands want it loud. Link to comment Share on other sites More sharing options...

I think that you will need to try them out to see if they do the job for you. I'm not convinced one way or the other. Link to comment Share on other sites More sharing options...
Members Vinny D Posted February 10, 2010 Members Share Posted February 10, 2010 I would say a realistic crowd covered outdoors from your rig would be 200 people max.I would certainly look into renting either (4) more LS700P subs to go with what you currently have or, (4) SRX/QRX 218 subs properly powered. The subs you currently have are great indoors for crowds of around 200 people but outdoors they run out of gas quickly. Link to comment Share on other sites More sharing options...
Members derrick Posted February 10, 2010 Author Members Share Posted February 10, 2010 Abzurd, you have a rig very simular to mine how many people do you cover in an outdoor show with your setup? Link to comment Share on other sites More sharing options...

Here's the deal: The idea of "covering" is very subjective. It depends on way too many factors, like how noisy is the area, nationality of public, age, etc... Can your system sound nice and your audience have fun? Yes, I think so...Is your audience going to have a "concert like" experience? No, they won't...Kick and bass will be heard, but not felt. People will be able to enjoy the show and still talk, which is not a bad thing IMO. Be extra careful with the mix and EQ. Intelligibility and clarity are more important than loudness and a nice EQ'd main vocal can make the difference. Besides that, enjoy your time...

Members RoadRanger Posted February 10, 2010 Members Share Posted February 10, 2010 hi guys, i'm thinkig of going smaller and lighter You imply that you presently have a rig that "does it" for you - what do you presently have and do you need the new rig to match that in SPL and low end or can you give up some?

I honestly don't think the 4 impluse 1012 can cover 500 folks outdoor for RR unless, there is a big ass bass amp and guitar amp is a 100 watt tube amp. Since your budget is about 2 grand, if you can swing a few more bucks and find a dealer willing to cut you a deal, a pair of JBL SRX 715s would work out for you . They are only about 50 lbs a piece and the orange badge says RR. The PLX 3402 would power them nicely. But then I don't think they would cover more the 300 folks out doors. Your subs are the weak link. For 500 folks, I would run at least 4 double 18s or some nice horn subs. Link to comment Share on other sites More sharing options...
Members derrick Posted February 10, 2010 Author Members Share Posted February 10, 2010 guys thanks for all the imputs guys keep em coming.i have peavey sp1gs but the are just too heavy. for small shows i have an old pair of jbl sr4722a which only weights 57 lbs, but i'm reluctant to buy two more and use 4 for outdoor shows because of the 100/100 horn pattern and comb filtering problem. i've not read of anyone using 4 of those splayed two per side.

Members agedhorse Posted February 10, 2010 Members Share Posted February 10, 2010 100 vertical is not what I would choose vertical for outside due to wasted power, though they may have enough high end biamped to get away with it. The comb filtering issue may not be an issue at all in practice. I have a couple of these in the shop for a rebuild, when they are done maybe I will give them a listen side by side.

Members derrick Posted February 10, 2010 Author Members Share Posted February 10, 2010 i would appreciate it very much if you could splay them side by side and let me know what you findout.i could buy anothe pair of the jbl 4722a and use those for outdoor gigs.
