In pics #2, and 3 (side shot) you can see the triangles. My woofer pads are the size of the woofers. The woofer pads are mounted before the woofers, so you cannot see how the pads are screwed to the triangles that were glued to each side of the horn. Any pictures of this? While I like the idea of the woofer mounting pads screwed to the triangles glued to the horn as it eliminates any tapping directly into the horn, I'm skeptical that since those woofer mounting pads AREN'T glued or screwed directly to the horn that they will vibrate against it. iI had thought of doing multiple layser of the triangles, but it is too much effort for a little bit of stiffening gain...plus the support for the horn stiffens the cabinet stability already. The horn is supported by the 2 uprights that are angled from the bottom platform and the woofer mounts. There is zero load on the horn even with a 30lb EV driver so the driver isn't attached directly to the horn flange but to some kind of intermediary support like on the Klipsch K402 stand? as the whole horn behind the dual layer MDF baffle , is sandwiched by 3/4" MDF which is in turn is supported by 2 1x3x3/4" pieces of MDF which is screwed to the woofer mounts. Pictures?
I am using the Kappa 15c woofers as they were also recomended by Chris and several others. I bought the woofers right after Chris came out with the MEH, and they have been sitting in their boxes until now. I am planning on making 2 more MEHs in the future for a 5 channel setup.
The woofer mounts are 3/4" MDF. The mounting screws to the triangles were counter sunk so that their would not be any interference to the 15" woofers
Any testing done here in OB mode?

As far as the OB the woofer do fire forward through the horn...so this will be to me another way to try the MEH. It might be a total failure as a OB, but I can always add a cabinet to it
I meant that the tweeter doesn't fire to the rear..
19 hours ago, Negatron said:The speakers are already pushing 200lbs each, and will def be a good amount over 200 with a cabinet. We have constructed this to where we can still take it apart for shipping if we want to, as the horn can be removed from the front baffle. Whe the horn is removed only theb1 side triangle would remain as they are glued with construction adheasive, and the woofer plates attach to them with screws.
Got any pics of the horn with the triangles glued on? Did you countersink the holes on the driver side to make the depth of the port "appear less" to the woofer as Chris did?

I don't see where the EV driver is braced/supported here...?
For some reason I thought I saw somewhere about why you were using different (smaller?) woofers than the Crites 15" Chris used. Did you already explain that somewhere?

[/quoteCurrently what I am doing is supporting the EV DH1A driver only, but I I am thinking of also supporting the woofer mounting pads. Currently it is resting on a t channel setup, but later I hope to have it supported with MDF or solid wood. My EV DH1A weighs about 30lbs, and each woofer is about 15lbs. The first version (which is what I posted up ) is going to be tested as a open baffle setup with the intention that a sealed cabinet can be attached to the speaker setup frame. I will be assembling the 3rd setup this weekend, and also the framework for free standing or a cabinet. The k402 horn protrudes out of the 1 1/2" thick front baffle and is sandwiched between angle cut MDF. In addition we used construction adheasive to attach 2 triangular shaped pieces of MDF...this is then used as a mount for the woofer mounting pads by screwing them to the the glued triangles. Currently we are using silicone to seal the woofer ports, but when we disassemble it all to veneer the cabinets... I will use clay (just in case I ever need to remove the horn from the cabinet).
Yes, fascinating project! Got any more pictures of the initial setup/evolution? Still plan on testing as "open baffle" (not sure how that would work when only the woofers fire to the rear) and if so wouldn't the baffle have to be much larger than what your pictures show so far?
If already going to a sealed cabinet without OB testing, why have the horn protrude from out front? Won't that be difficult to seal off? Why not have the horn lip seal to the cabinet front much as it does with the KPT-305 which cabinet Chris used for his MEH?
Speaking of the KPT-305, Klipsch went to the trouble of enclosing the back of the 8 inch driver in that mid bass module in a metal can - really sealing it off inside the 305 box. Maybe our evolving MEH designs should go in that direction?

Interesting. Are these ripped as DSD/DSF?

Why would this improve anything?
It might not, since I've found that the Oppo 103D is converting the DSD/DSF to PCM. Then again it might since it's a simpler way of playing the files - no computer software involved. For me who has become aware of noise in my system even when a computer is working on the same household power circuit (not connected to the audio system directly analog or digital) this point seems important currently (no pun intended).
Maybe I'll find software playback superior if nothing else for the GUI and cataloging/tagging features and this noise issue to be "in the weeds". :0)

No confusion for me. What is the threshold of audibility of the types of DAC performance measures that he presents?
When you realize that the reviewer never really talks about those subjects (and is really the Achilles heel of all his reviews), then you can begin to look at the data itself and decide for yourself if it's "good enough". I've stated this observation on the forum before. His data is good, but he never says "good enough" and moves on to more important issues. This is a problem.
I have no problems with the performance of the DACs in the XMC-1 being much more than "good enough". Can I hear any differences between the current AVP that I own and the one it replaced (in terms of DAC performance)? I'm not sure. And that's "good enough" by definition. If I were to start asking questions about other parts of someone's setup, particularly the room acoustics and loudspeaker performance in-room, I think that these measures will show much, much greater audibility and lower performance thresholds. I could go on with examples of this, but I think you know what I'm saying. DACs used to be an issue in the 1980s through perhaps 10-20 years ago. Spending time on them now is a waste of my time as long at the SINAD is below -100 dB and DAC clock jitter performance is better than 1 ns (in fact, these thresholds are probably overspecified). It's like worrying about cables and interconnects. These are largely a waste of time and money if they're simply "good enough". Get out your calibrated microphone and REW (or similar measurement application) and start looking at the end-to-end performance of the system. It won't take you a nanosecond to figure out that DAC performance is literally "in the weeds". I worry about other stuff that actually matters to what I'm hearing.
I find that it is the failing of hi-fi enthusiasts without much experience to not ask these type of questions and to pour money into electronics, etc. without first asking the question, "can I hear that difference?" I can't tell you in how many instances where I see all their money spent on electronics and a pittance on loudspeakers and room acoustics, then the same individual tries to shift the subject away from the obvious "elephant in the room".
Chris
My confusion stemmed from thinking you were referencing his review as an illustration of the superior performance of the XMC-1's dacs. Now I understand your greater context. Thank-you and well put. Actually, as I've stated before, following you over the past year or so has awakened me to the "macro" issues in home audio and what is "in the weeds".

The reason why I recently sprang for the NOS XMC-1 is due to the DAC performance, which bested the other AVPs (and AVRs):
Confused here. I didn't read through all 11 pages of that thread but the review conclusion makes clear:
"Even without that problem, we still can't match performance of a $99 desktop DAC even though we paid $2,500. Yes, we got more channels than 2 and have room EQ but still, I want my good performance damn it!"

Yes, as SACDs. I did use the external HDMI input on the Oppo when I was having trouble with the HDMI connection from the computer (which turned out to be a HDMI cable issue of the weirdest sort--which also caused me to acquire the Emotiva along the way...jeesh). It worked (external HDMI inputs to the Oppo), but it really was a kluge to have to turn on the Oppo in order to route digital files to the AVP
Actually, I meant the Oppo directly playing the ripped DSD/DSF files from a usb drive connected to it or over a network share/ethernet not HDMI in, but, after some experimentation that might not be a very attractive way given it seems to convert DSD to PCM:

Glad you're home and on the mend Rudy.
-
Interesting, I may need to check out the foobar2000 interface for myself. Have you tried them directly on the Oppo? If the Emotiva has analog inputs you could also play around with which DAC sounds better (although those differences may be swamped/moot by the DSP you're doing) Any noise penalty for having a computer directly hooked to the system?
-
Yes, it's great to have immediate browse-ability of most of my collection. (I still have some bluray-audio disks to rip.) I'm getting addicted to the presentation/GUI of Tidal in Roon but only for 2 channel (the Oppo 203 can't be a multichannel Roon endpoint).
Do tell though Chris, I saw you post about software player options, but, how are you getting those new ripped DSD/DSF files to your Emotiva? Just playing them on the Oppo 103 which ripped them with your 2TB usb drive connected?
-

More on topic here’s what DSD/DSF looks like on the iPad controlling the oppo 203 first in Roon (which I believe transcodes the files into its own format) and the Oppo Media Control app (which I think doesn’t)

...Now I'm looking at Blu-Ray external disc drives from Amazon in order to rip my Blu-Ray music collection. I think this will enlarge my multichannel collection to 200-250 albums, and significantly increase my enjoyment of these albums, too.
Chris
Chris, thanks for that Tag&Rename info. I'll be investigating that.
If like me you're also interested in ripping UHD Blurays I found lots of helpful info on the MakeMKV forum including a guy named Alex who set me up with a drive and case with UHD compatible firmware. I got:
5.25” Bare Drive ASUS BW-16D1HT with Libre Drive mod
and
-OWC Mercury Pro USB 3.0 enclosure for full sized drive.
This setup works on my Win10 usb 3.0 laptop and older Vista usb 2.0 desktop with MakeMKV and RedFox AnyDVD.

My computer is picking up the MiniDSP 2x4 as the output. It may be the settings in the MiniDSP software. The instructions are just ok. I’m sure I am missing something simple. Usually the case. Just super frustrating!
Here's a look at the MiniDSP software settings that give output from my laptop usb connection. Note on the input tab that "usb" is selected and in addition to showinig "connected" that it's not "muted". It has an unconventional mute switch. Both have an "x" but the muted state is red.

Not really on topic but here's the Oppo 103D firmware on which I'm ripping my SACDs to DSF

Playback from the NAS of the ripped DSF files btw is over ethernet to an Oppo 203 controlled with an iPad using the Oppo Control Media app.

...I've never had the ability to rip SACDs from my PS3s and Oppo BDP103 since the manufacturers of both units prevented this ability in their firmware updates (which were then made non-reversible),
...I have some SACDs that respected the DSD format and the recording/mixing/mastering chain respected that "no editing" edict of DSD, and I have to say that these discs (especially the multichannel versions) are perhaps the best that I own--because the bass line EQ hasn't been tampered with. There are three Yellowjackets multichannel SACDs which are like listening to the original downmix tracks, and they're absolutely superb--reference quality sound--like being there.
Chris
I've been ripping my MCH SACDs to a NAS share with an Oppo 103D for the last couple months. I'll check my firmware version on the off chance that I can help Chris. Totally agree about the one Yellowjackets SACD I own - Altered State - now I'll have to get the other 2!

What are we thinking is a fair range for these? They do have the Crites xovers.

PM sent.

No experience with Ashly but the 2 Xilica XP-4080s I have are very quiet and good sounding. There's just no substitute for the control and resultant sound you can get with active.

Keep us posted on what you hear, please. I am very interested in your impressions regarding soundstage and depth as compared to whatever you had previously.
Probably won't have much to say about soundstage and depth given this mono setup or is that a misconception on my part that soundstage and depth are mostly qualities inherent to stereo playback?
Not much time to listen to this last week. I set the bare AMT-1 stack to burning in using some moderately loud pink noise for 12 hours at a stretch while I was away at work, so, over 3 days maybe 30 hours of pink noise.
Just running Chris' settings for the Belle bass/AMT-1 at the moment so I must break out the UMIK-1 and REW to even begin to dial it in. Just on the gross level of balance between the Khorn bass bin and the stack I am once again amazed at how much increased bass tames the perceived brightness and how much decreased bass emphasizes it. A small twist of the Nobsound bass amp volume knob radically changes the character of this blend. Our hearing is incredibly relative!

Initial listen promising 😺

Thanks Ron! Those pics are helpful. I can see how the silicon around the horn cutouts would damp vibration. What silicon compound are you using? I still don't see how the driver is mounted to the horn. Is it direct to the flange or to some intermediary support?
