It is, but neither of the examples you linked would be capable of a lot of bass in any event. For what you're doing you would be better off with more of the smaller model spaced closer together than fewer of the larger spaced further apart.Is it overkill to buy a speaker capable of lot of bass with a larger cone if it’s only used for vocals in a conference room?
So I should be better off going with NSIC600WH 6-1/2 size speakers spaced closer together than going with NSIC800WH 8 inch speakers?It is, but neither of the examples you linked would be capable of a lot of bass in any event.

Yes. With a distributed system you get the best results when the speakers are closely spaced, to minimize the level differences throughout the room. That said, you'd be better off with a larger number of much less expensive speakers than the Yamahas. For instance:So I should be better off going with NSIC600WH 6-1/2 size speakers spaced closer together than going with NSIC800WH 8 inch speakers?
You are correct. It is more of an auditorium that will have about 50-80 people for a place of worship. Mostly it will be single voice of a single lecturer. Sound quality and evenness throughout the room are equally very important.Though I think we need a lot more details, I'm inclined to agree with others. More speakers spaced closer together. Though we don't know how many speakers you planned to use.
But, it depends on what you are trying to do. You specifically said this was a conference space, not office space. So, is this the PA system for large conferences? That is, several people in seats and one person in front making a presentation? How many people? What is the ambient noise level? What kind of presentation? Will there be any presentation aid - Video, Slides, computer interface, other?
Will people be presenting video presentations? Will this simply be the single voice of a single lecturer?
A 48ft x 21ft room, indicates this is more like a small auditorium.
The devil is always in the details, the more details about precisely what will be going on in the room, but better we can advise.
If we limit it to the two drivers you suggested, either one will do the job. So, now the question becomes how many speakers, place where, and for what purpose?
Depending on the circumstances, a big PA in Front, might ....might... be better than a lot of speakers spread around.
Yahamas were on sale so I purchased 22 Yamaha NSIC600WH speakers and 18 Yamaha NSIC800WH speakers. I was trying to decide between the twoYes.

You also need to set this up as a 70v system, using the appropriate transformers.
You mean I should go with 21 speaker configuration instead of the 10 speaker configuration I had in mind before right? I think coverage of these speakers is between 6-10 feet radius. Should the speaker’s microphone be located within this radius or outside this radius?I can't quite make out the dimension, but you've configured in about right. Assuming some isles on each side, as it is now, that puts pretty much each person within 3 ft of a speaker. I can't imagine that not doing the job.
But remember what I said about the Front of the room. If the lecturer moves too close to the front row of speakers, he is likely to get feedback in the microphone/amp system. As long as he stays behind that line, there shouldn't be a problem.
The configuration in the drawing looks like 12 speakers, 6 on each side. That seems fine. Again, I can't make out the dimension on the drawing but it looks like between 5 and 6 feet. That means no matter where you are sitting in the room, you are no more than 3 ft (horizontally) from a speaker. That should give you pretty good coverage.You mean I should go with 21 speaker configuration instead of the 10 speaker configuration I had in mind before right?

I assume the configuration I described would not need another mixer right?
Thanks for your help.

Wait, I looked at the diagram again, you have FIVE Speakers on each side. That doesn't matter, based on by best guess of the dimension, it sill puts everyone within 3ft of a speaker no matter where they sit in the room.
I think you are on the right track now. It is just a matter of managing the wiring, and determining what support equipment you need.
There is a need to have at least 1 speaker in the adjoining hallway. That’s why I can’t install all 12. It want look nice if I install 11 speakers in a square pattern. I have to either go with 2 columns of speakers or 3.Unless I am mistaken, you have a 12 channel amp, for best results, one speaker per amp channel seems like the best choice. So ...up to... 12 speakers makes the most sense.
Currently in your diagram what is the width between Columns, and then the distance between Rows?
If we allow 3ft for a isle on each side, that makes the listening area about 38 x 15, which is 570 square feet. Divide that by 12 speakers and that is 1 speaker for every 47.5 SqFt. Or roughly 6.89 ft between each speaker. The farthest you can be from a speaker is halfway between two of them, which puts you, on the horizontal plane, 3.44ft from the nearest speaker.
As I suggested, in the first couple of row, you could put 6.5" speaker because people sitting there will get both the PA and the Lecturer's natural voice. Those farther back will not be able to hear his natural voice as well, and likely bigger speakers will server them better.
With two columns of 6 speakers each, for a total of 12 speakers, if we make the first two rows of two 6.5" speaker, and the remaining 4 rows of two 8" speakers.
When you determine where to space or place the speakers in the room, don't think of the room's overall dimensions, think of the listening area. There is little point in putting a speaker directly over the isle.
If my best guess is right and the listening area is 38ft x 15ft, the divide 15ft by three to determine the location of the two columns of speakers. That would mean two columns 5ft apart centered on the room.
These are details that you can work out on your own though.
But you can look at speakers in isolation, you have to consider the amp that they are working with. In this case, assuming you haven't changed, you have a 12 channel amp. That somewhat implies ideally 12 speaker, or less ideally 24 speakers.
So, using my dimensions, the speaker columns will be space about 5 feet apart, and SIX speaker row along the length of the room, will be spaced about 5.4 feet apart. Given this, not matter where you sit in the room, you will be within 3ft of a speaker on the horizontal plane. That puts everyone reasonable close to a speaker.
Again, you have to look at the complete system and how it interact with itself. Perhaps, the amps can be daisy-chained together, so that two 12 channel amps could act as one 24 channel amp. But if you have more speakers, consider the density.
You suggested 21 speakers, though an odd number is not going to work, It has to be 20 or 22, not 21.
I'm not even sure how to space 22 speakers. Probably 18 speakers in three columns of 6 rows. But if we allow for an isle on each side, that places the speakers in rows with 3ft spacing. Yes, you can do that, but 3 feet seems pretty close, and would probably require an additional amp.
You need even numbers of speakers, and you need to consider how many amp channels you have to drive the speakers. Given that you've chosen a 12 channel amp, which seems a good choice, logic says the best speaker combinations if 12 speaker evenly spaced over the Listening Area.
I think, you are a little too focused on the size of the bass drivers, when that is the least of your problems. I think either size or a combination of sizes will work just fine. Rather your real problems are finding the correct equipment or combination of equipment to drive the speakers.
Thank you for your input. I think I now have a pretty good idea how to tackle this project taking into consideration everything you said. I think it’s very good idea to do a dry run of the speaker like you said so I can gauge how the speakers will respond before cutting the holes.You can have UP TO 12 channels on the amp you have. So, 10 in the room, and 1 in the hallway would work reasonably well. Remember you don't need Rock Concert Sound levels, you merely need to re-enforce the speakers voice so everyone can hear him. The actually volume levels don't need to be that high. - 75db to 80db should do nicely. Just equal to or a bit more than face-to-face conversation.
I would suggest one speaker per amp for up to 12 speakers, unless you want to add a second amp. Though you can try two speaker per amp, but that will generate a lot of heat and risk overheating the amp. Though, with a lecture you won't be straining the amp that much.
You could have 11 in the room and one in the hall, you just have to decide where to put the one odd speaker. If you have two columns of 5 rows for 10, then between a matrix of any 4 speakers, you could put the odd additional speaker.
I would test a dry run of the speaker, with the speaker connected to the amp, but just sitting on chairs the the approximate position they will be place, then have some one simulate a lecture at the front of the room and move around and see how it sounds. Likely 10 or 11 speakers in room, will do just fine.
