Column PAs
« on: December 25, 2021, 12:19:05 PM »

We're looking at potentially getting a "stick" / column PA. I like the idea of being able to wall-mount the tops. Has anyone perhaps compared the JBL PRX One, HK Audio Elements and db Technologies ES1203?

For what purpose?

If you were mowing 2 1/2 acres and were asking about how well an 18" battery power lawnmower would work, I would advise you against that and suggest something with a 60" mowing deck and at least 25 HP.

Our church is moving into a beautiful old, but acoustically challenging, building. It's an old style stone church with a big echo. The audience zone is about 18m deep and 9m wide. Someone suggested we look at a column array (as proper line array is above our budget) and I've been intrigued, especially with HK now bringing out the 15"  elements sub.

I was wondering if anyone has done a comparison between the options, as obviously not everything is readable off of a spec sheet.

Well.. at least you're asking before buying. Column speakers do work in these spaces if distributed down the length and delayed, and a little less well if deployed as a distributed system with no delays. The key is to keep the SPL from any given column low enough that it doesn't excite the room too much or overlap with the coverage of the other speakers.. and of course they have to be elevated and pointed down at the listeners... not pointed at the far walls. Two speakers of any type at the front pointed straight back and cranked up so it can be heard in the back rows will do nothing but excite the room and be an uninteligible mess for spoken word.

Is that HK system designed to be separated and mounted? Most of the portable stick systems only work with the stick mounted in the sub, but JBL, Bose and others have columns that are designed for installation.

That's kind of the reason I'm particularly drawn to the HK. It allows one to stack the array part as high as you want, has an install kit which allows for tops to be wall mounted, the new 15" sub has option to set delay and then it also has independent tops (with their own amp) we could setup as delays midway through the room. My main concern is whether they'll have enough punch as the advertised SPL isn't particularly high.

I've heard SPL numbers aren't necessarily consistent across manufacturers so was wondering how it compares to the competition. And then obviously how the sound quality compares

You can't power your way to clarity in a highly reverbant room like this, the only two solutions that work are (lots of)room treatments or multiple speakers that are only just loud enough to be heard.

Have a look at the Danley column speakers.  The vertical pattern control is outstanding. Itís a wide horizontal pattern so it lends itself better to a center fill, at least in your situation (I think).  Model it in Danleyís prediction software. 

Renkus-Heinz also has good solutions but itís steering, and likely pretty expensive.

Thanks. I'll definitely have a look at those. I guess I should also mention I'm in South Africa and not all the makes/models are available here.

I was just reading up about the dbTechnology ingenia series which is also pretty cool.

It looks like Danley has distribution in South Africa.  Iím sure Renkus-Heinz does also.

I have used the Danley SBH10 and SBH20 and they are excellent sounding speakers with very good vertical pattern control.
They are not your conventional designed column speakers!
They won't fix the acoustic problem with your room but will sound better at a distance than most other speakers.
