Selenium ADM25-25 Horn Adapter
Selenium ADM25-25 Horn Adapter is rated 4.25 out of 5 by 8.
Rated 2 out of 5 by from caution using bolts suppliedI bought these plates to use on my Selenium compression driver. The holes all match up perfectly. However the bolts supplied do not fit. The holes in the driver are metric, the bolts are standard. No problem, I just went and picked up some new bolts at the hardware store, I brought one of the other bolts to match the length. Guess what? After putting in the new bolts, they bottom out without being tight. I can understand someone mixing up the metric and standard, but the length too. What if someone tries to tighten them down and damage the driver? A little better quality control in order.

Rated 5 out of 5 by from Simple Idea.Dear people at Selenium. You've just saved me a lot of frustration and time. Thank you. I wanted to replace Klipsch 1 inch drivers with JBLs. But I wanted to keep my Klipsch horns. Now I have a JBL 2470 driver on Klipsch horn in no time.

Rated 5 out of 5 by from good designIv'e used this adapter in a few projects. The reason I'm bothering with this review is because of the versatility of this product. The aluminum is thick enough to file/drill to match with any bolt-on. One compression driver I used it with had non-standard mounting holes, no problem with the Selenium ADM25-25.

Rated 5 out of 5 by from does the jobIt does exactly what you would expect it to do. The only thing I want to add as a caution is, if you thread this onto a metal horn/ lens, make certain to apply some 'pipe dope' to the threads first or else you run the risk of the aluminum threads binding up and you will not be able to remove the adapter later. Remember: pipe dope (it's a plumbing thing).

Rated 4 out of 5 by from Not preciseThe passage is not constant in cross section area. It's bigger on the driver's end and smaller on the horn throat's end -- it's not expending, but shrinking! So from the phase plug of the driver to the horn, there're 2 odd steps already. It definitely needs some more works.
