made a template and routed the opening on my beater LS cabs.  Worked out fine...

 

I did something similar a while back, maybe got the idea from you.

While browsing the picture files saw this one of the clear Klipschorn. Paul Klipsch really was a genius.

An art object on the wall of a hotel lobby that functioned very good as an acoustic diffuser.

I have a picture of these and PWK with my ex-wife from back in 1985 during my visit to Hope. They are spectacular when you actually see them in 3D! I remember reading that it took 1,300 man hours to build!! They wanted to use a Laser to measure the cone motion on the Khorn at 120 db output, or some such thing, to verify that the woofer did not move more the 1/16th of an inch at full output!!!

I once made a thick clear plexiglas panel for the woofer access door on a Klipschorn so I could watch the woofer. Never did see any cone motion.

There you go. It's why horns are such good acoustic transformers. The resultant miniscule cone motion is a direct result of that optimization which reduces Intermodulation Distortion much faster than the gain in efficiency!

My friend is doing some work on his house, so we brought my KW-120 subwoofers and KA-1000 amp back to my place. Decided to try them with the Klipschorns in the garage. The pair of 12" subwoofers may be undersized for the main speakers, but they sound good and get plenty loud.

I use the 2Ultra 2  subs and ka amp with Jubilees, once dialed in, work very well in my yamaha system!

The Klipsch KW-120 subwoofers and KA-1000 amp system sound really good. The set I had are now back in my friend's home theater, but this time he insisted on paying for, and keeping them.

The garage Klipschorns have been inspiring me to improve the appearance of my workbench area, so I wrapped mahogany veneer around the water heater.

I had an extra pair of DE-120 drivers, so when I read a thread about a forum member swapping out his CT-120 horns, I asked if they were for sale. I want to thank @pbphoto for selling these good as new horns at a great price and really fast UPS delivery.

That burl veneered K-402. 😲

 

Beautiful!

 

Thanks. The burl finish on the K-402 pictured earlier is a vinyl wrap. I plan on replacing it with better looking real wood veneer so that it matches up with the genuine wood veneer of the bass bins.

Bought a case of Sound Seal acoustic wall panels. Made of one inch thick rigid fiberglass and covered with Guilford acoustic cloth. Several of these on the walls of a room make the room sound better.

Just a random picture of a nice room in a house I visited. Audio system was conspicuously absent, but they did have a separate home theater room with some brand X speakers.

ok, so it's intervention time....  repeat after me...."I have a veneer everything I can touch problem"....

 

Gads, I don't want to see your dog!  lol

 

Though I WOULD expect him to be end-grain matched.  :emotion-14:

You may be right. Everything I have shown you so far is just practice for when I get around to the veneers that require a higher level of expertise. I am now experimenting with different dye stains for my next project.

If these are your practice runs to deal with your learning curve, it will be nice to see what challenge is ahead of you when you're done with it.

Had some big old cabinets sitting around, so I pulled the original sub drivers out, veneered the cabinet faces and swapped in some 18" Ultimax subwoofer drivers, shown here inside out. These Ultimax have dual 2 Ohm voice coils, but for my application I connect the voice coils in series to give the amplifier a nominal 4 Ohm load.
