  1. 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.

  2. They are K402 MEHs. The holes are for the 2 woofers. Sent from my SM-T830 using Tapatalk
  3. 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. Sent from my SM-G935V using Tapatalk
  4. 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.

  5. 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
  6. 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
  7. 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
  8. 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
  9. 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.

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

  12. 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

  15. When I receive a package I handle it with gloves, and let it sit outside for a day or two, then I open it with gloves on. Next I take the contents, and let them sit outside for a day or two...then I bring them inside the house for use. Sent from my SM-T830 using Tapatalk

  19. USPS is great for shipping EV DH1As....just use the flat rate box... the square one works perfectly. Sent from my SM-T830 using Tapatalk
  20. I would ask them to send you a replacement and this time o ly the card. I have found a lot of the vendors will even mod the products very cheaply. Sent from my SM-T830 using Tapatalk
  21. In the past if a person had a CPU cooling fan with UL markings on it, and was legit, but had a heat sink attached it was deemed counterfeit too, but his would only happen whe USC sent a pic of the product to the Patent/Trademark holder, and they confirmed it was counterfeit. This is done because it could end up in court. Now this also means that there was a Trademark and or Patent infringement that is registered with USC...if not it can not be seized. I have been purchasing China audio amp cases from China, and none get seized.. I am assuming it is because of 2 reasons... The dimensions are not the same, and the Patent/Trademark for this model is no longer valid. I no longer work daily doing this, but this is the way it was when I left in 2011. Years ago you may recall seeing adverts in all the major newspapers in the USA by HP stating they were supporting Microsoft the best OS ever (at the time HP was a Linux supporter)...this was because they had been caught with millions of dollars of products with Microsoft's logo on them and had not paid the fees to Microsoft. Microsoft was registered with USC, and hence they were protected. HP reached out to Microsoft (I am assuming since all the shipments were released after the advertisements). Now one more thing.there is also Grey Market protection which is when a legit product is sold out the back door. Your board could very well be legit, but a Grey Market product. I do not recall a product being seized for being a Grey Market product, but it is possible. Sent from my SM-T830 using Tapatalk
  22. I now have k402s. These were originally going to be for my surrounds, but I now have RP160Ms for the surrounds. The 18x10 ZXPC clones are def very strong as they are made about a 1/4" thick plastic. Sent from my SM-T830 using Tapatalk
  23. US Customs only seizes models that the Patent Holder still pays to protect, and when a Patent expires or they stop paying the Government for the protection... it is no longer protected. Sent from my SM-T830 using Tapatalk
