Bare stack on Khorn BB mono in dining room nearfield with Chris' Belle/AMT1 settings on MiniDSP 2x4 HD.

A little surprised to see you using them this way Chris. Active dsp no doubt. How do you get it to mate well with the Khorn bass bin clone? Can I PM you for your current Xilica xdat file?

Welcome Rolox! Excellent first post - nothing like relating your real hands on experiences.👍. I'll also be installing some 15cs soon in my FH1s and may take some measurements before and after. What about some of this 8mil "foam" self adhesive insulating pad on that horizontal panel? https://www.amazon.com/dp/B01KAD24RI?psc=1&ref=ppx_pop_dt_b_product_details

Sorry I haven't been able to contribute here as planned. My mom died yesterday at age 88 after a long decline into Parkinson's disease. I'm grieving her with my family.

Lift Off!!

wow, that is quick. Looks like foam stuffing rather than any kind of panel damping. Just stuffed in there behind driver? Not attached to anything. While I have my FH1s apart I'd like to do any easy/prudent stuffing/damping/tweaking

Gotta find time to get the 15cs installed. I'm curious about damping the doghouse too. Link to Klipsch video? I watched 2 but didn't see damping.

I will do the same. Maybe we can standardize between our test setups somewhat. I plan to have the AMT test stack on the triangular Khorn bass bin cover pictured above sitting on the Khorn bass bin - no top hat - in the corner with several layers of thick fuzzy padding at the foot of the bass bin. What REW settings should we use on the AMT only? A test sweep from 300-20k? Bare walls in the corner and on the walls to either side of the test setup or some kind of absorption/padding? Test level? I'm using the UMIK-1 mic with 90 degree calibration file. What distance and height of mic?

I'll make incremental progress evenings this week and see if I can get some measurements to you this weekend Chris since I'm still pretty remedial when it comes to interpreting/presenting them. Current plan is to tie the current triple hinged wings together with top, bottom and side plate assembly with threaded rod similar to Rudy's but with a hinged single back wing set in addition sitting on one of my Khorn bass bins.

That last screenshot shows how to open or restore settings from the computer to the device - click Presets then click the radio button "Set Current Settings (File open as xdat)" You can then use the standard navigation window to wherever you had saved your files.

Saving in the 30 slots on the device is certainly one way. I like to save to my PC. PC like this:

thanks for the explanation Chris

Was this taking off of the phase response above 300 Hz not seen last year when we married the K402 to the Khorn bass bin and crossed around 450 Hz?

3 wings right.

HInged some together. 2 wing set.

1 wing set

No wings "control"

I had some rough tops I had cut when I had K402s on top of my Khorn bass bins. Thought they would make a serviceable base for this test rig(s).

Isn't it great how sharing ideas sparks our interest and creative energy. I may start to build a test rig this weekend too or at least get some measurements for how it could come together. Let's keep supporting each other in this. Placing the wood on the table saw is a step in the right direction 😺 and a curve, well, waayy cool!

Poor drawing but you get the idea. A test rig with a sliding base to vary that extension side and nesting wings to vary those.

Is this where you mean? Is it critical to get this as tight and seamless as possible? More generally I imagine a test rig that allows forward and back sliding of the driver/wings on the base and "stacked" wings that fold out for 2x and 3x or more lengths.

Any better practices those of us that are getting close to building one should follow? Stiffening of the horn? Attaching woofers differently? Padding on inside of box surfaces needed? Has any further development of the physical design been done? Thoughts on more efficient cutting of the horn? (not sure how you did it ) Perhaps some way to take a single "plug" out that would be relatively easily replaced/reversed. Perhaps a template file we could print out? Pictures of this? Suggestions on procedure?

Wow, I’ll be following this 4shoo 😸👍. I have all the ingredients to do them except the woofers.

Glad it worked out same day for you Gary. It was fun to visit another Klipschee even more obsessed than me! That’s one hellova center you got brewing there 😸

Just got off the phone with Gary. Look forward to seeing/hearing on Friday!
