Goldwood GM-500PB 1" Horn 1-3/8"-18 TPI
Goldwood GM-500PB 1" Horn 1-3/8"-18 TPI is rated 4.4444 out of 5 by 9.
Rated 3 out of 5 by from Not the best fitting hornsThese are replacement horns for a set of Nady PS115 piezo horns. They are use in conjunction with some Pyle PDS442 1" Titanium Horn Drivers. The horns actually work and reasonably well. The problem is getting the 1 3/8" thread of the Pyle Drivers into the thread on the back of the horn. We tried to seat the drivers all the way down - wasn't going to happen. They are firmly seated about 1/2 way and are quite secure. Possibly the metal thread liner on the horns is a bit too snug. Don't know.On the plus side, they were easy to install. All of the screw holes matched with the cabinet and they sound good.

Rated 5 out of 5 by from great replacement hornI used these to replace my horn in my carvin 1540 2 way speakers. I blew the hf driver and couldn't get a replacement from carvin. unfortunately the driver was epoxied to the horn so I replaced the horn with the Goldwood GM-500PB 1" Horn 1-3/8"-18 TPI(it is an exact match) and the hf driver with a Selenium D220Ti-16 1" Titanium Horn Driver 16 Ohm 1-3/8"-18 and it fits perfectly and also blows away the carvin stock driver

Rated 5 out of 5 by from Perfect fitI had purchased a set of used cabinets - unloaded. It was very important to find the horn lens that fit the 22A drivers and 115 cabinets. These had to be the exact size that had been in the cabinets from the factory. The dimensions listed were very accurate. They sound great and have metal threads. They should give years of use! Thank You, Parts Express!!! I ordered on Friday evening... received on Monday morning! :)

Goldwood GM-500PB 1" Horn 1-3/8"-18 TPI

Is there a recommended weight limit for the driver used with this horn? I noted that one person who purchased this horn used a Selenium horn that weighs in at 6 lbs. total weight. That seems a bit heavy for this plastic horn. Thanks.

Asked by: davguitar
Goldwood does not provide a weight limit for this horn.

Would these work for an Optimus 990 replacement?

I blew a tweeter in one of my 990s a few years ago and have been searching for either a tweeter to fit in the original horn (haven't been able to find one) or replace the horn and tweeter. Anyone know if this will fit in the cut out?
Asked by: Fastrid
The size of the hole required for this to fit in the enclosure is 13-5/8" x 3-3/4".

What is the horizontal/vertical dispersion of this horn?

Asked by: Chaz H.
Most PA cabinet horns are 40 x 90. There are other tighter configurations for special applications which might be used in an array(with overlapping patterns) but these are not nearly as common especially from an entry level or hobby application.
