Don't these types of acts usually bring thier own PA equipment? Weddings are social events so while there is usually music people want to be able to interact, so covering the whole space with the same SPL is usually not desirable.

Yeh, they do but like I mentioned, I am purely doing the acoustics and warned the owner that choosing loudspeakers is up to the audio engineer and you will need a good one, not one that just sells you the stuff but as the "expert" in town I am just doing my homework to be able to consult a little more than just the acoustics.


My experience doing wedding over the past 40yrs is that you only need speech coverage for the whole room and the higher SPL capability should be directed at the dance floor as much as possible.

Can you please confirm what you mean here? You mean two seperate speakers for speech and music? I get the part having music directed at the dance floor. But how do i cover the whole room while having the dance floor covered...?

Speakers should always be aimed at the listeners and not the surfaces as much as possible, ideally that would mean flying them near the ceiling and angling them down.

Yes, your correct I was thinking having them toed in with the main coverage aimed at the dance floor but the end of the 90 degrees away from the closest wall. I get your point, probably best to aim them directly to dance floor though a little toe in shouldn't hurt. So even a point source could be hanged from the ceiling?

There is no getting rid of all reflections indoors especially at low frequencies. The ideal speaker system for your venue may have a much narrower coverage.

Well, Im going to work hard to tame the low frequencies. When you say much narrower coverage are you saying more narrower than 90 by 60 aimed at the dance floor? Overall it seems your recommending a point source over line array?

No that is a gross over generalization, to achieve that response the array would have to be floor to ceiling in your venue. The array (aka column speaker) you are more likely to chose would only perform that way at mid and high frequencies.

Interesting. I get the basics of line array but need to read up a little more.

Line arrays are often not the best solution inside buildings but that doesn't stop people from using them. You are doing the right thing here education yourself before equipment is purchased, as you can see there is more involved in selecting the right equipment and then getting them correctly installed than you may have realized.

Yes, and certainly more than the basics on the net. The audio engineer recommende JBL VRX series which is line array but I thought that point source would be better.

Ive been around a while but I am into small room acoustics, home 2 channel with DSP or digital filters and just making sure that the right speakers are bought for the hall to complement the acoustics that the owner will fork out on.
