    A K-402-Based Full-Range Multiple-Entry Horn

    in Technical/Restorations

    Posted

    Those came out really nice. How is the horizontal coverage with them rotated like that?
    My room is 19' wide and with them angled in to where they are aimed right at my ears...center image is right on the money and the sound stage extends to the sides of the MLP. So I have about a 180 degree soundstage... I like it because you are emmerced into the music.

    Can't say as I built my MEHs to be that way to fit in the corners and be floorstanding (I wish I wolud have made them taller so the horn throat would be lined up with my ears though). My Center is the normal way, but it is mounted on a short stand that angles it upward to the mlp. Here is a pic of one next to my acoustic panel.c47525306c47a9132e5ac8114af85962.jpg

    Glad to hear box volume isn’t a real issue. I’m thinking of reorienting my 402’s from vertical to horizontal. I feel as I move around the room the coverage is not consistent.  I feel switching to 90degrees horizontal will improve coverage, and allow them to sit deeper in the corners. 
    I am able to get mine a few inches from my corner bass traps by running mine on their sides.

    Has anyone used EV DH2A Drivers and HP940 Horns?

    Are they the ev dh1as kr dh2? Your post says dh2 but the thread says dh1. My friend is running the ev dh1as in some ev horns that I believe are the 940s... he crosses over at 500hz to his La Scala bass bins as I recall.
    They run up to about 17k, and he runs I think a 10db shelf around 12k. I can contact him and get the specifics if you like.

    An attempt to build K-402-MEH clone in wood

    in 2-Channel Home Audio

    Posted

    Since the room i am planning to place the MEHs in is kinda big and has very little furniture in it, i was thinkiong about placing diffusers on the walls. As of now, the room is very echoey.
     
    I already have 6 Leanfusers prebuilt and i was contemplating on making 4 more. Here is how i am going to place them:

    image.thumb.png.172e1503c293459a3dea96a791f58a86.png
     
    The room is about 6 meters wide and 12 meters long. Ceiling height is about 3.1 meters. Listening position is about 3.5 meters from the front wall.
     
    I was also thinking about placing filling a 3x3 meters space on the ceiling that is between listening position and front wall with 2D 60x60cm diffusers in a chess fashion. To make them lighter weight, i was thinking about making them out of XPS of maximum density i could find.

    Of course, i will put a carpet on the floor.
     
    What do you think? This is what can be done relatively easy. Should i expect some nice results?
    In my last house I used the mirror trick and did my first reflection points for the side walls and the ceiling with 4" of Roxul R60. We also put 2" Roxul on the front wall, and had a bass trap in all 4 corners and the rear wall with Roxul R90...it was right on the edge of being too dead. I had a friend of a friend over 1 night and we listened to Steely Dan Aja and he said it was the best he had ever heard outside of the studio. He was a musician and also had his own studio...plus he was in the Studio when Steely Dan recorded Aja. We really loved that old 2 car garage room in a room build. Now i have a room that will be impossible for me to ever get to sound the same, but at the same time the cubic feet dimensions are 4 times larger, and walls, ceiling and floor are all concrete, windows, and marble. I def have a much livelier presentation that sounds like a club, now. Hopefully I will be able to get the reflections down more with my panels and rugs...we will see when I tune again.

    If you place the horn mouths within 2 feet (0.6 m) of a side wall, I then recommend a line of 1" (2.5 cm) thick laundry-lint-type squares of 2 feet by 2 feet dimensions (0.6 x 0.6 m) placed just adjacent to the horn mouth exits.  This will dramatically help to recapture the phantom center stereo image, in my experience.  You can experiment using more squares just around the horn mouths--out to perhaps 6 feet (2 m) radially.  You may need to place more absorption along the side walls, carpet on the floor, etc. to help control the nearfield reflections to the loudspeakers--and the listening positions.

    I made some 2' x 4' x 6"  (stuffed with 2 Roxul R60 2" layers) for each side of the horn mouth. We will see how much of a difference it makes next time I take measurements.

    You could always mod them to MEHs, and put them on end...less than 4' high. Drape some acoustically transparent material over them and put a heavy piece of artwork on top...and they have disappeared.

    Tube Traps DIY Homemade

    No, I gave them to a friend years ago. Now I just use DIY bass traps. Back when I had the diy tube traps, I also built some diy diffusers too...which also had the plans available for diy users. Both were excellent products and if you cannot afford to buy... I highly recommend making some.

    I have to disagree in that the design and performance of the ASC Tube Traps are of the highest quality and their performance is well documented and has optimized voicing per the reflective performance which is a critical design feature IMHO. The build quality is also of the highest quality and I have some that are nearly 20 years old and would be impossible for someone to tell the difference between them and the new ones I’ve purchased recently…
     
    Yes they are expensive but well worth the investment in my opinion and experience.

    They used to have the plans available and I made mine per the plans. I never said that ASC tube traps were not if the highest quality... I said they were worth it to make your own and save money.
