Dayton Audio RPH20 20" Round PA Horn Pair

Affordable, durable horns for demanding sound reinforcement applications. The re-entrant style horn flare design provides an expansion path that is longer than conventional straight horns; this ensures that the lowest possible frequency response can be achieved. The Dayton Audio RPH-20 PA horns are formed from lightweight aluminum and painted with a durable polyester finish, so you know that they will survive years of exposure to sun and rain. Great for indoor or outdoor applications, sturdy mounting yoke for precise alignment included. Standard 1-3/8"-18 threaded throat; 20" mouth diameter, 13" depth.

Dayton Audio RPH20 20" Round PA Horn Pair
Dayton Audio RPH20 20" Round PA Horn Pair is rated 4.5 out of 5 by 4.
Rated 5 out of 5 by from Very controlled patternI recently installed 4 of these to cover the stands at a raceway. they covered the area well where they were directed, but even a few degrees off axis they attenuate rapidly. Be sure to plan your installation for the roughly 60 degree sweet spot. They are quite efficient, so moving them back works well if you need more coverage.

Rated 5 out of 5 by from Excelent value, Incredible performance.When I plan to install a public adress system, I usually go and order one of the speakers that we choose before we really go through with it . mainly to see if its cut out for the job, and this one is great. The performance with vintage University sound drivers is great.I am keeping this one. the 5 others, I will install.The horn has good construction. The only bad thing is, the bolts supplied were too short, but I have some and it worked out fine. the sound is alot deeper that the old rusty originals. very clean.

Rated 4 out of 5 by from DuckworkI used two of these with the Dayton 75 watt drivers. Sound is good and clean, efficient with little power needed, fine with low power amps. I had a little trouble with the U-shaped mount, the bolts supplied were too short, requiring a Lowes run to get longer bolts. Metric bolts were supplied but I found that 3/8" x 1-1/4" from Lowes worked fine. I plan to glue the little plastic inserts into the horns to keep them from turning when the bolts are tightened. If you're willing to put up with these problems, you'll have some nice outdoor horns for half the price of name brands.

Rated 4 out of 5 by from Great for the money!I coupled this horn with the Dayton D1075T and installed 4 in a local football stadium. Impressive frequency response for a pa horn! On the first test we got a clean echo from a tree line about 500+ yards away at half volume. Need I say anymore?

what is the coverage pattern for this horn

A general purpose, average - e.g. 80x80 - would be OK, actual graphs at different frequencies would be better.
Asked by: taco66
Up to about 90 degrees.
