Dayton Audio IO525B 5-1/4" 2-Way Indoor/Outdoor Speaker Pair Black
Dayton Audio IO525B 5-1/4" 2-Way Indoor/Outdoor Speaker Pair Black is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Good Clear SoundGood Clear Sound. I installed 4 of these at a restaurant along with 2 JBL and they sound a bit better than the JBL's, crazy. They aren't as well sealed (exposed wire connections) and the mounting only allows for swinging one way, JBL's are ball mount. Add a sub and the sound is fantastic.

Rated 5 out of 5 by from Easy install, appear well made, very good soundThis review comes from a school in CT. I use (8) outdoor speakers on the chain link backstop on our ball field for music and player intros. When those speakers were installed 4 years ago, I purchased them online elsewhere & a different manufacturer. This spring, I noticed two of the speakers were damaged (impact). I searched for the old units I have which are no longer available. I found these IO525B Dayton speakers on PE. I noticed they had a similar shape and bracket as my old ones. I took a chance & bought a pair. I am writing this review one month after install.-They look great-I was able to re-use my old bracket which was a bonus-The metal push-down wire holders on these DA's are a better design than my old screw on terminals that had corroded.-The sound is much better than my old ones. The bass is tighter and louder and the vocals are clearer.Very pleased with purchase.

Hi, what level of wattage is ideal for these? I have some 160W amps and don't know if they'll be right for it. Thanks.

Asked by: MisterJ
That will be more than enough power. The speakers are rated for 40 watts RMS, so anything at or above that will be fine. Just keep an ear out for distortion, if they don't sound right at high volume levels they need to be backed off a bit.
