@babadono, I am glad you asked. When I read about your wood adapter project a couple weeks ago, I thought of this aluminum adapter as an alternative, but I was really impressed by your wood sawing skill with that project.

I may have bought it from US Speaker.com / speaker accessories / horn adapter. In my picture above, the adapter on the left has the screw on mount added by me for my application.

Thanks. I learned about that great idea by reading the Klipsch forums.

These tri-amped speakers are part of a totally separate stereo system from the other speakers in the room. They are temporarily modified, but just like the others, these Klipschorns can be easily returned to original condition when desired because I saved the parts for that purpose.

I keep reading good reviews about the Hypex.

The surround channel speakers at the back of the room had at one time also been modified for the fun of it, but have since been restored to their original condition with the minimal effort of spinning some screws and re-installing the parts.

There are magnets beneath the veneer for attaching a grill, but the exposed horn looks good in this room.

Thanks for the link.

Here is some info that might help.

One of my friends asked me why I wear ear plugs while riding such a quiet motorcycle. I said it is so I don't have to listen to his annoying loud exhaust.

Klipsch forum members are the best technical support group in the entire audio world.

The guy appears to have met a lot of interesting people during his life, collected a bunch of rare things and also enjoyed listening to Klipsch speakers.

I have some of those on a pair of speakers. I like them.

The cabinets are looking good. Your fabrication and assembly methods are excellent.

The close up images are cool. I like how the guy explains the way he prepped the surfaces.

As mentioned above, the jumper wires should be connected, as shown, along with the other wires in their proper places.

I have a pair of Brand X speakers next to the K-horns for occasional comparison and demonstration purposes. They measure a fairly flat frequency response and sound nice, but when doing an A-B test between the Brand X (subwoofers ON) and the K-horns (subwoofers OFF) at matched SPLs, the K-horns sound more lively and musical. The Brand X don't get played much. When the volume goes up, the Klipsch have the huge efficiency advantage and there is no fair comparison.

Yes, I agree. Even if the subwoofer is rugged and capable of excess excursion, it will ultimately perform and sound better when all the inaudible, unwanted subsonic signals are filtered out. @Westcoastdrums , Your MBM21 looks awesome. I bet it frightens your neighbors who have survived some of the big SoCal earthquakes. 😮

I care that forum members are happy. So, I have contacted the seller. He tells me that there is ONLY one K-402 / K-510 assembly included with this set that was removed from an old movie theater.

The K-55 mid driver aligns better with the narrow throat of the two piece adapter on the left, than it does with the slightly bigger throat of the one piece adapter on the right. It may be a trivial matter, but sometimes the small details add up during the pursuit of excellence.

Klipschorns are great speakers. It is good to have them in a listening room that allows the bass bins to perform properly.

It is good that you also have the original back panels. Keep them, because you may want to put them back on.

You will need to bypass the internal crossover when converting to full active. I suggest labeling the internal wires to the woofers and tweeters, disconnecting those wires, then adding new wires (and wire clamps) that will connect the woofers to the woofer amp and different color wires from the tweeters to their amp. This way, you can easily return the speaker to its original condition, if and when you decide to upgrade.
