Threaded Drivers?

**Carl Bill** · May 13th, 2010, 03:21 AM

Is there an adapter made to allow a threaded horn to use a standard 2 bolt 1" Altec driver?

I see 1-3/8" threaded spec's and wonder if this is OD or ID?

I have only used Altec, JBL and Emilar bolted drivers, so no experience with threaded horns/drivers...

Appreciate any help.

What you need is a Selenium ADM 25-25.
SELENIUM - ADM25-25 - Horn Adaptor

I think they're available from a number of different suppliers.... (Parts Express, etc)....should do the job.

The P.audio is a little nicer and a couple more bucks...

Thanks for that link to P Audio Old Guy....I'll get some of those for my K55's....I don't really like the Selenium ones, as they are a plastic material (but you have to use what you have available) & have been searching for some better aluminium ones.

The Selenium ones I have are aluminum, and they look identical to the ones in the pics.

I think the Selenium female threaded one is plastic, it's a POS

Suspect that is where the confusion is. AFAIK the male is metal

For some reason in the US it seems you can only get the PC-35
Horn Lens Adapters - all - LoudspeakersPlus
But hey, it's only a ten spot.
