Pyle Indoor Outdoor PA Horn Speaker - 9.7 Inch 20-Watt Power Compact Loud Sound Megaphone w/ 400Hz-5KHz Frequency, 8 Ohm, 70V Transformer, Mounting For 70V Audio System - PyleHome PHSP101T (Gray) Grey

I have been using these in different warehouses for a while without issue. Crisp sound and good function. I have no idea why I would spend more on a more well known brand - there's not substantial difference.

I'M USING IT TO REPLACE A 15 YEAR OLD SPEAKER UNDER A PATIO COVER. DIRTY AND DAMP PLACE.

I love it, I have a 100 watt amplifier and I was building an air raid siren. I got two of these and popped them open immediately. The first thing I did was remove the transformer since I don't like transformer amps, then I ran the input wires straight to the compression driver so I can use it like a passive speaker. I plugged them up to the amp and tested a wailing siren tone and set off the neighbors car alarm, so yeah it's plenty loud!

Does the job well and seems very solidly built. Has some heft to it. There's a rotating switch on the rear for the transformer tap selection. Also allows standard 8 ohm operation instead of 70v by just turning the selector switch to a certain position.

This is a very well constructed PA horn. The instalation is very straight forward with a helpful guide on the back of the horn itself. It is very loud, we used it along with a Pyle home audio PA Amp (40 Watts) and we are using only one of these and now it's easier to find people around the shop!

Works fine, plenty loud - we put three of these in a 100x200 warehouse driven by a 35 watt amp. Plenty loud even when power tools are running.

Speaker arrived and I connected the (Black) ground wire to my amp , and the (White) wire to the 70 volt terminal.the sound quality was terrible. I realized after testing that the wires were connected to the transformer were swapped. Just heads up to anyone that has this problem. Obviously a mistake at the factory. The sound quality is decent for the price I paid now that the cables are connected properly.

Ordered three speakers to replace three that are from the 60s or 70s. As they are connected via 70volt, we can vary the number connected based on the event. Instructions are minimal but effective. Very pleased with the purchase.
