Small Bar Audio Setup 70v

post #1 of 6
Thread Starter 
Hi Guys!
Looking for feedback on our simple bar audio setup. I attached two images for what we're planning, hoping it's correct and will work. The space is about 1220 sqft, enough sound for clear music, weekend sports games and occasional acoustic performances, doesn't need to be nightclub loud but it needs to be loud enough.

Crown 14M > Crown CDi1000 Bridged Mono 140v > EDCOR WS100 100W transformers > Behringer B212XL Speakers


The speakers will be mounted at the red X's on the walls, there will be 4 (for now) TV's also on the walls. Pretty limited budget, ~$2000, so if you have any suggestions on a different components that'd be excellent.

Any help at all? I tried writing Sweetwater but have not yet heard back from them. Any help is much appreciated! smile.gif

With only four speakers and the room size shown, you really don't need a 70 volt setup. Just put two sets of speakers in series and then put the two sets in parallel tied to the bridged mono amp. This will give you exactly 8 ohms and better overall sound quality plus save the cost of the transformers.

You could also run stereo with a set of speakers in parallel on each channel. That would present a 4 ohm load per channel which is well within the limits of most amplifiers, especially the Crown. Be advised that stereo may not be the best option for background music/TV. Mono might be better acoustically based on your room layout.

Low cost 12 gauge speaker wire is fine at the distances you indicated.

We were leaning toward 70v just incase we needed to add more speakers and leave setup simple. Putting the two sets in series-parallel can work if the sound can get loud enough. I don't have any experience with larger cab speakers, do you know if those Behringer's look like they can provide the work we need with that amp?

Well power is power. The series/parallel setup comes out at 8ohms which is ideal for the amp. It will deliver full rated power to all four speakers. The 70v system will actually only deliver what each transformer is set for within the amps total power rating. So you would probably get more power to the speakers with the series/parallel connection. In addition to limiting power the transformers also restrict frequency response. For PA system this is OK but fine music quality will suffer. Either way it should get plenty loud enough.

You are correct in that beyond four speakers you should go with a 70v system. You could run the wiring so that either system can be implemented. By creatively using four wire speaker cable, you can set this up to go either way.

Didn't even know the four-wire cable was even a possibility! Thanks for the input, very much appreciated. smile.gif
