Synergy style horns

[NBPk402]

We are finally in Mexico. I have a Klipsch k402 that is going to be the testbed for the synergy horn. I have a bunch of projects to do over the next year, and will post them up as I get them done. First will be my new diy AV rack, followed by some new diy speakers for the living room, and then i will work on  the synergy horns..

Today I listened to the v1 all mdf that we built...I was very surprised as to the bass output, but something didn't sound right.the horn sounded like there were veils to be removed. My friend and I listed to various songs, and sometimes it sounded great, and at other we heard resonances. On one song we heard things that we have never heard before on that track. The song was Luka by Suzanne Vega.What we both heard was best described as her smacking her lips when she speaks. Has anyone else ever heard this(we did not hear it on the other channel with LA Scala bass bins, and EV horns with EV DH1a drivers)?

When it came to the bass it appeared to go much deeper than the La Scalas setup and having a much warmer sound compared to the La Scalas.

My friend is going to run REW on it again to see he can see what might be causing it to have this effect. We are thinking part of it might be we need to turn the gain down on the woofers as there are 2 compared to the La Scalas 1.

Conclusion so far is when it does something right it is really right, but at other times it needs something...

Show the REW sweep when you have it. Will be interesting to see the response.

It will be interesting when I run REW again as our new room has zero treatments with clay walls, ceiling, and floors, and my old JBL setup was in a fully treated room on the edge of being dead. Also I only have the Klipsch 402 which will be the one modified...my friend has the first version made entirely out of wood at his house in a small room about 10x10 , and heavily treated. I am not sure if he is using it or not as I left it with him instead of paying $2 per pound to ship the beast.

I will post up pics of the completed speakers...now I am working on a smaller version.

Update:
Here is 1 speaker with my acoustic panels when I measured with REW.
The rest are shown in various stages of completion. Inused them as a cabinetless speakercuntil we got the cabinets made.

I now have 1 clamping jig ready for making the wooden 2' version, and hope to have at least a cabinet less version ready by Christmas.

It has been quite awhile since I have been on here, but here is what I have completed so far.
1: finished 4 K402MEHs,... address Mesquite hardwood to the rear for the mounting pads and the adjoining horn walls, and had a custom paint matched to my cup washers on the F20 horn subs.
2: returned to cabjnetless design, which gives me a more tube like sound in the under 500hz range.
3: I have 2 Celestion 15ftr3070c woofers per MEH. Only the top horn has a compression driver (Celestion axi2050) 
3: At first I wired each horn woofer pair as one  for each Fosi v3 monoblock per woofer pair, and comp driver. Then I decided to clean up the wiring (saved 1 meter per channel), and rewired  amp 1 to left channel, left bottom woofer, to left channel top woofer. Then amp 2 was wired the same, but with the left channel right woofers. I really likemthe way it came out, as it sounds better now.
5: Next i set my levels for 1 pair of woofers per channel, then the other pair, I do the woofers first as they are the least efficient. Next I matched the level of the comp driver to the 2 pairs of woofers per channel. Then I finished off with the f20 pair of horn subs and hooked them both up to the Xilica and summed both the left, and right channels as one output and then split that to each sub. The subs are currently crossed over @60hz. I did this because I have a dead channel on the Xilica. Then I set my mid crossover to 500hz, and tuned from the MLP.

Setup really sounds great now!

Are you still in Mexico? (Sorry if that isn’t where you moved to. It’s been a while)

Yes!, we are still in Mexico,but in 2027 we plan on moving to the EU. This time I am taking everything I have except the Marantz av8805a and the LG 86UN8570PUB TV as they are only for USA, and would be worth nothing in the EU. I am hoping this summer to have enough saved to get a Storm ISP 16 or 24 MK1 used as a replacement.
