@gjacobse Ok so what amplifier would you recommend? Is an amp really needed?
you could use something as small as this:
https://www.amazon.com/Pyle-PCA2-2X40-Watt-Stereo-Amplifier/dp/B001P2VV50
If 20 Watts is enough in each speaker, that should be fine.
-
So any recommendations on ceiling tile speakers that are low cost, decent quality?

Yep, sure could. Just don't tell @art_of_shred.
If I continue to ignore him, he can't bother me.
-
Would these suffice?
There is a 70V transformer version as well, double the cost though.
-
Audio isn't cheap. A few hundred dollars is the cheap end of this solution.
-
@Dashrender So what would you recommend for speakers?
-
I could use these which have a 70V transformer build in, and it's a 4 pack.

I don't have a specific recommendation. The last time I did one was more than 10 years ago. I purchased a typical home receiver, ran speaker cables to the speakers, and an input cable to the cable set in the middle of the room.
The speakers and amp kinda need to be matched together, this shouldn't be hard, and Art definitely knows a lot more about this than me.
-
Paging @art_of_shred for recommendations on a speaker amp combo.
-
So this is what I have for an existing parts list, tell me if I'm insane.
RCA Audio Splitter to support 4 speakers
RCA audio cables - 6 foot long
-
@DustinB3403 You already bought/own these parts?
-

No, building a list of things for the conference rooms.
-
You don't need an RCA splitter (thats just silly).
Get a set of RCA cable (Red & White, Yellow is composite video - which you don't need) long enough to go from the projector to your amplifier location.
You need an amplifier, a 2 channel amp will easily drive 4x 8 ohm speakers (2 per channel)
-
So just the RCA cables I have listed, to the AMP, and from the amp to the speakers, basic speaker wire.
Gotcha.

I hit enter before I was done, let me edit my prev post
-
@FATeknollogee So is what I said correct though?
-

Yes that is correct.
Just get 4x 8 ohm in ceiling speakers (you don't need 70V speakers)
"Most" modern 2 channel amps will drive a 4 ohm load without any problems.
You get a 4 ohm load, cause you wire 2x 8 ohm speakers in parallel for the left & right sides.
Make sense? -
For what you're doing, since you only have a single source, there's plenty of inexpensive amps to choose from:

@FATeknollogee yeah that makes sense, and your recommending not using these specific speakers as the 70V isn't needed.

Remember "KISS"...no need for 70V, you only have 4 speakers.
There's a time & place for 70V & this ain't it...
