Have an old 8x24 with a Bogan TPU 15a Currently they have two horns hooked in series and 1 parell , when I add one more in Parallel , the two that are in series drop right down in the weeds the single is not affected my question is if I were to wire in a new run to one of the horns in series and make them all parallel would that fix the problem , any info would be appreciated these horns are in 4 different warehouses North east south and west and to try and wire all in series would be a career all 30 ft ceilings on a ladder tks in advance

you don't have enought watts to power anymore horns you have to get them a new amp to add any more horns. you need to get at 30 or 60 watt amp you can go on bogen web site and they can help with anymore help as far as how many horns per amp and how to wire them www.bogen.com

Please list the type of horns being used.

If you're setting up at 70v, wire all speakers in parallel and set the taps on your horns such that the total wattage does not exceed the tpu15a unit, which is 15 watts.

You need to check each horns impedance to see what you have. Do any of them have transformers on them?

Thanks for the info , will get the ladder out tomorrow and see what the existing horns are set at but I think they are just those 2 wire pre set ( no option) white plastic under the dirt that is..tks for the quick replys
