I was by no means implying the problem was with Chris. Chris has bent over backwards to get me up and running. It is just s series of computer problems since I installed the Xilica software, and REW. Murphys Law showed its ugly head and anything that could go wrong did. The last result we had before I messed with trying to get the compression driver up had the setup sounding considerably better. I am positive that if I had not had the failures in Windows we would have a superb sounding setup right now. Ever since we moved to Mexico I have noticed problems with various pieces of equipment...at first I thought it was the electricity, but when we bought our new house ai had voltage stabilizers installed to get the voltage down from 135v, and I have recently noticed the voltage has been dropping down to 115v. I have most of my equipment plugged into UPSs, and my amps are plugged into a APC HT power Center with a voltage booster. I have another UPS coming in so I can use it for my amps. The one I have coming in is a sinewave UPS so hopefully this will work nicely too. This week I have 50 Hockey pucks arriving for feet for my AV rack, speakers, and amps to rest on. I will disassemble the AV Rack, and then start reassembly. I have a new i7 NUC that is still another week out from delivery (all our mail is now being brought down once a week due to the border restrictions instead of twice a week).

Well as usual something goes wrong... After a 3 year long project to build these, I finally get the speakers to the stage where they are ready for tuning. First I have problems with my Windows PC changing to a black screen every few minutes. The only way to stop it was to plug it into the Dune HD Pro 4k players input. I thought everything was good, but I noticed REW only had left and right showing. I blew it off and tried working with it, and Chris started his tuning. At more than one point Chris A suspected a problem with wiring, and I double checked and it all seemed fine. Occasionally I would notice the tones did not seem correct in REW, but we continued on. We got to a point where Chris said the compression drivers could not be brought up to the bass levels...tried various adjustments to no avail. I decided to change the amp gains to try and get the horns up to where it was proper for the balance. Chris sent me another tune to work with, and I thought it looked good after I adjusted the levels, but the levels were way off because I was measuring with the window being 50db...which is of course not good. So effectively I messed up all of Chris's hard work. The next day I go in to REW, and the tone for the bass appears to be the tone for the compression drivers again. I then discover that I have zero bass coming out of the speaker, and the Xilica when the tones are run is hitting 1 LED up from the bottom instead of getting up to the yellow on the LEDs. I then try to change the drivers in Windows 7, and there are no other ones. I then try to do a fresh I stall and now it doesnt even show the audio hooked up in Windows. I have now ordered a new i7 NUC to replace my ASUS mini pc un62. I should hopefully have it up and running in a couple of weeks (I have to wait for it to be shipped to me in Mexico). Hopefully Chris will have the time and be willing to help me get this to sound great. Now of course this is all during the Corona Pandemic, with me having a pacemaker/Defibrilator, Enlarged Heart, Cardiac Sarcoidosis, Asthma, Allergies, and Sleep Apnea (basically I am in poor health from all my previous activities in life). This puts me at the top of the list to die if I get the Corona virus. I stay home 90% of the time, but with the news showing the virus is getting worse finally in Mexico...good chance I am screwed. I get more and more depressed everyday over the current situation. I am hoping I live long enough to be able to enjoy all the time and money invested in my setup. Working on my setup and enjoying it are what keeps me from my depression getting worse. My wife tells me I should not tell people my health condition, but I tell people because I appear to be ok, and I want them to know I am not as I appear to be. As an example...if I catch a cold it lasts for sometimes weeks, and is like a bad flu to me. If I get the flu, it lasts for about a month, and I have trouble breathing even with meds. Last year my allergies got so bad I could only sleep for 2 to 2 1/2 hours a day, and that was only because I passed out. Of course now if I get the flu, it is to dangerous for me to even go to the Dr as I have an even greater risk of getting the Corona virus...so I am in a lose lose situation. Please everyone take this Corona virus seriously and try to survive, and protect yourself, your family, and friends. Sent from my SM-T830 using Tapatalk

My setup is pretty different than the other 402MEHs... I would ask Chris A to assist you, he is the expert on the k402MEHs. Sent from my SM-T830 using Tapatalk

Yup...not likely that we will learn anything at all from this...we have very short memories. It never matters to anyone until it affects them personally. The younger generation seems to treat this like a normal flu, hence all the people wanting to continue life as normal...going to the beaches, parties, movies, concerts, etc. This mentality has to stop or we will be doomed when it hits again (if we even make it through this pandemic). I have zero faith anyone will learn anything at all. Sent from my SM-T830 using Tapatalk

Well this was done in Europe a few years ago where the Government paid all the mortgages off, and did not bail out any of the Corporations. You have Bilionaires who will lose absolutely zero and in fact most likely will make money off the Corona virus with all the write offs they will get...all along not paying any taxes. It is time people wake up and stop catering to letting the Corporations and 1%ers run the Country. Sent from my SM-T830 using Tapatalk

A 1 time check...it will. Ot even pay the Bill's for the average household for 1 month, and this is likely to last much longer than the USA is letting on.i would not be surprised if this is a Corona year, especially since people are protesting to be able to not Quarantine. Sent from my SM-T830 using Tapatalk

Nope, and like a $1200 check is going to help anyone. Stop bailing out the Corporations, and the stock market, and start paying people's bill for free until this is over, so the people have a chance of surviving. Sent from my SM-T830 using Tapatalk

I do not think they will be the losers... Our Government likes to bail out the rich without helping the middle class or poor, and they will do it again...we will pay for it in higher taxes and more government cuts. Sent from my SM-T830 using Tapatalk

Chris is working on my settings for the crossover and the changes in sound are amazing! Chris has awesome skills! I am actually surprised how nice the no cabinet version sounds, though I will still build a cabinet to see how it sounds still.

We love it..of course we are now self Quarantined. Hopefully I will not catch Corona, and will be able to enjoy many more years of my retirement. Sent from my SM-T830 using Tapatalk

The horn driver? If so it is attached to the stock mounting. The woofers are screwed to the woofer pads (currently with 4 1/4 20 bolts. Once we get everything veneered and ready for the final assembly I will add 4 wood screws to attach the woofers to the woofer pads. This will mean a total of 8 attachment screws per woofer. We are not doing the wood screws yet as we will be taking them apart at least 1 more time, and wood screws in MDF do not like multiple use.)...which are screwed to the side mounted triangles. Sent from my SM-T830 using Tapatalk

They are K402 MEHs. The holes are for the 2 woofers. Sent from my SM-T830 using Tapatalk

Here is a pic of the triangle with the woofer pads, and supports removed. 2nd pic shows a woofer pad laying in position. The woofer pads are rock solid and are attached to the horn with silicone for now via 6 screws that go into the sides of the glued triangles. Once we have finalized everything and veneered it... I will look at either clay or glue to adhere them. If I glue them I cannot disassemble the horn I do not have measurements yet as I am having problems with my windows pc and REW...which gives me sporadic readings.

I believe the office panels are made with Owens Corning compressed fiberglass. I prefer not to mess with fiberglass and went with the Roxul Rockwool for my last HT, and will be using it for the new HT too. As far as the office panels being better I doubt it very much, as testing I have seen posted shows the Roxul as being as good as the Owen's Corning without the hazrd of Fiberglass.

A friend of mine has a HT that is in a 10'x12' treated room with a 5.2.4 setup with La Scalas and it sounds great! Sent from my SM-T830 using Tapatalk

When Inmade mine I found out that the redwood 1x4s were much lighter than the pine 1x4s..so I used them for my ceiling panels. Sent from my SM-T830 using Tapatalk

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. I 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 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. I am using the Kappa 15c woofers as they were also recommended 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. Sent from my SM-T830 using Tapatalk

Please excuse the mess. I was working on the framework for the speakers most of today, and I have 3 MEHs ready to wire now. I do not know when I will be able to buy more MDF as HD, and the lumber yards are now closed in our area. At least I will be able to enjoy them as OB until I can try a cabinet. A cabinet will be made to where it can fit the existing structure. Once I find out which way we like it I will be getting them veneered in Mahagony that way. 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. As far as dealing the horn to the baffle...we have 2 layers of MDF, and also overlapping as the easiest way to do it was to angle cut a sheet of MDF into 3 pieces, and then angle cut the other way to remove the center area for the horn. It is pretty solid right now, and when we do the final build on it we will also seal it off with caulk. 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. Another reason for not having a simple box if footprint...in order to minimize the footprint we also needed to raise it off the floor to get the horn center closer to the correct height. If we mounted them the way everyone else does it would have been much wider, and we would have to raise them off the floor even more, The last pic is why I have the horn protruding the front baffle. I liked the design and wanted to do a MEH like this non MEH speaker. I also wanted to try out open baffle to see how I like it. As far as the front baffle being wide enough...time will tell, and if it is not and a box sounds better, it will have a box. Sent from my SM-T830 using Tapatalk

I have no bracing currently I am making a support setup today. I am also planning on a 2 piece cabinet plus access that will tie into the support setup. I am still debating on how I want the cabinet to be shaped and still allow it to be removed if desired. If I were to guess, I would say currently the setup weighs 150lbs+, and by the time it has a complete cabinet it will be over 200lbs. Double wall MDF is very heavy.

Not sure...Chris suggested this was the way he would do it if he was me. Sent from my SM-T830 using Tapatalk

Today I picked up all the pieces for the front 3 horns, plus a spare....minus veneer and cabinets. Starting tomorrow I will start on the backbone frame, and then decide on the cabinet shape, and design. Once we test one without a cabinet, and another with a cabinet... I will then get them veneered with my Mahogany veneer. Hopefully they will be to the listening/tuning stage sometime next week. Sent from my SM-T830 using Tapatalk
