Klipsch k-74-k horn tweeters

I got a pair to use with my Altec 811B horns. The tweeters are crossed over with a 24 db/octave active crossover at 9.6 KHz with the horns band passed at 24 db/octave from 1.4-9.6 KHz.

My initial impression of the Klipsch tweeters is that they sound very good with the Altec horns.

Only question is how to mount the tweeters. I thought about just drilling four holes in the Altec horns and using the four lower mounting holes of the Klipsch tweeters, but how well will that hold up over time?

My other option would be to go to my local Lowe's and get some metal pieces that I can mount on both sides of the tweeters using only the top and bottom mounting holes on the tweeters which would require some spacers behind the mounting holes to clear the horn. Going that way would also give me a convenient attachment point for securing the wiring so if the speaker wires get pulled it won't damage the connections at the drivers.

The tweeters will be driven by a Dynamic push pull 6BQ5 stereo amp I just got.

What I have done untol a permanent mount is to get so 1/2" x 1/8" flat stock aluminum-something easy to form bend- then get some of their industrial Velcro and cut into stips wide enough to fit the flat bar and then you van temp mount the aluminum anywhere you like with the Velcro. You can even put Velcro tabs on the tweeter for a temp thing as well.

I would want it to be a permanent mount.

I was thinking for the purpose of testing before mounting- once you find the spot then you can bolt it right up!

Oh ok I didn't know that. My plan is to mount them in the center of the horns on the top like the ribbon tweeters are now that the horns are replacing.

I must say that the Klipsch horns integrate better with the Altec horns.

I decided to just go with my original plan and just use the four bottom mounting holes. What I did was to mount the horn from the front so the horn would provide a little support of itself.

Once I repaint the Altec horns I may remove the drivers from the Klipsch horns and paint them the same shade of green as the Altec horns. That way they would look better together.

Well since I have finally got this system set up right except the Dynamic ST-500 6BQ5 push pull stereo amp (waiting on parts for restoration) I find that I am satisfied listening at low volumes just as much as I am cranking the stereo up loud.

In fact I have been playing it at lower volumes not feeling a need to crank it except for favorite songs of course

Seems like the Altec 811B horns with the Eminence PSD:2002S-8 1" Titanium Drivers installed go well with the Eminence Delta Pro 12A midbass drivers and the Klipsch horns are nearly a perfect match for the Altec horns.
