Increasing sound quality in an outside venue

[hifiphones]

First of all I would like to say hi to everyone Great community with lots of useful information.
I am looking to replace the current speakers for outside parties.

The current setup is
2 x RCF TT25 http://www.rcf.it/products/touring-and-theatre/tt25
1 x Subwoofer DB Technologies, Arena SW 18, RMS power 600W http://www.dbtechnologies.com/en/pro...rena-sw18-p755

The setup is powered by a DPS 3000 amp , with an output of 2x 800W (RMS).http://www.rcf.it/products/pro-speak...fiers/dps-3000

The SPL is pretty good, but what we are lacking is sound quality. I am deciding between 4 x ELECTROVOICE QRX 115/75 http://www.electrovoice.com/product.php?id=191
or 2 x ELECTROVOICE QRX 212/75 http://www.electrovoice.com/product.php?id=193 to replace the two current RCF speakers.

What do you guys think, what would sound better? 4 15" separate speakers or the 2 with 2x12" inside?

Thanks,

The QRX are great boxes, but I don't think you will get any increase in sound quality over your TT25s speakers, which are also very nice.

You will get more output, coverage, which you say you don't need. But I do find a lot of the time I find that more rig just sounds a whole lot better, because it's not being pushed as hard or is hitting limiting (which is quite audible) a whole lot less often.

Thanks,

The area size is 8 x 9 meters, but as it is outside the sound spreads a lot. I will be getting 4 of the QRX 115/75 then. I hope they will work well in pairs (2 in each corner).

could you define 'sound quality' a bit more, please? Is it clarity, volume drop, muddiness, lack of distinction...?
Also knowing how your speakers are placed relative to the are may be helpful, and are you using this for live music or prerecorded. That space doesn't seem to be so large, but absent reflection there are inherent issues with outdoor set-ups.

[hifiphones]

Lets say we are looking for more clarity..we are playing prerecorded audio on these speakers. The area looks something like this, with the speakers standing on the floor (it is not possible to place them higher).



If we replace the current two speakers (15" woofer in each) with two 2 x ELECTROVOICE QRX 212/75 will we see any improvement ? As these have two 12" woofers each and a fully rotatable horn...

[daddymack]

I think your issue is not with the speakers but with them being on the floor. You are dumping a lot of sound onto the floor, and not getting enough up to ear level. Is there a way to tilt the speakers back at an angle?

Why is it not possible to raise the speakers? This is exactly what speaker poles were invented for.

Buying more speakers and aiming them poorly is not going to help.

[hifiphones]

Thank you for the comments gentlemen, unfortunately due to design conditions it is not possible to raise the speakers. The speakers must be on the ground, unfortunately we have to live with it.....

[B. Adams]

I agree with the others. The problem is that the speakers aren't elevated. You'll have the same problem with any speakers. Why isn't it possible to get them any higher?

[wesg]

Maybe you could convince your crowd to lie down?

More clarity? Turn off speaker 2

Probably not intuative but absolutely true as you will essentially cut the reflections in half

Does the design to alow u to put the 2 tops on top of the sub?
This wil also increase the quality a (little) bit
Also i think ure amp is way to weak for the tops, rcf recommends a amp of 2x 2000w
The sub is also to weak for these tops at 600w
Looking to the spl then it should mayby combine
Tops at 100db and sub 132db?,!?!?
Do u use a crossoverfor the tops?
Only the sub has a build in filter for internal use, ure tops getting also the full signal

[wesg]

Don - does that apply in an outdoor venue?

[dboomer]

Yes for almost everyone in the audience.

I am a little confused by the OP’s diagram as there are boundaries on four sides.

Or how about stack speaker 2 on top of speaker 1? Or stack speaker 2 on the sub and then stack speaker 1 on speaker 2?

Yes indeed
