PylePro 4x4 Inch Speaker-Heavy Duty 150 Watt High Power Horn Audio Tweeter System w/ 25mm Voice Coil, 15 Oz Magnet Structure, 1kHz-18 kHz Frequency, 105 dB, 8 Ohm Impedance-Pyle (PH44)

These are really well-built, they feel like they're 5 pounds each but probably just 2 pounds. The problem I had is the curve of the throat of the horn wouldn't permit the square outer portion with the 4 screw holes to fit flush against the baffle. The circular hole in the baffle is 5/8" thick, and I'd need to widen the outer diameter and angle inwards toward the inner diameter so the horn portion can go all the way into the hole. I might try it at some point, though I don't have the proper tools. Either that, or make about a 4"x4"-1/3" thick "shim" to seal the distance between the baffle and mounting plate. But I can't really say anything bad about the speakers, they are good quality.

Ok i just bought a pair of these horn to replace a pair of piezo tweeters i was a little uncertian about buying these horns but they were only 9 bucks so i thought what h3ll. let me tell this little suckers get the job done i was verry impressed with how loud and clear these ph44 are and for the price you can't go wrong i plan on getting additional 4 more of these ph44 and match them up with a pair pyle pro ph391 compression horns 4 by 10

Loud and clear but blew after a week because they didn't come with compactors I ran them assuming they didn't need them should have known better 3 stars simply because they worked excellent while they worked

Very nice and loud horns, just be careful, I recommend you buy a resistor and run it with these horns because I find they are easy to blow when ran for long periods of time

Excellent sound quality
