Nearly Full-Range Multiple Entry Horns (MEHs)
NBPK402 replied to Chris A's topic in Technical/Restorations
I made a fullsize attempt out of mdf a few years ago, and I will mount the compression driver like I did on my previous attempt. Now the previous attempt did not have the flare extension, but I did a mockup out of bendable 1/8" plywood that had the contours cut and they matched up fairly nicely. We will see how this one works out. I have attached an image of the rear of my first attempt. I have a k402 that I made a copy of the curvature of the short side of the horn with bendable plywood, and kerfed mdf. All 4 sides of my horn will be the same size so modeling off of one side should work. I am awaiting some 3/8" bendable plywood now I am planning on forming 2 pieces together for a 3/4" thick horn. Hopefully I will have the pieces ready by the end of the month. I only made the template to go from the flange for mounting the compression driver to the flat area on the mouth of the horn. I think I will have a picture frame style piece made that can be added to the front for the flat area. I am also thinking of making the pucture frame part flat on the backside, and curved to match the horn contour on the front...if this makes sense. 2nd image is the contour of the k402 short side template for bendable plywood.

Nearly Full-Range Multiple Entry Horns (MEHs)
NBPK402 replied to Chris A's topic in Technical/Restorations
I am working in a 2' (approximately) cube MEH. It will be using my EV DH1A driver and most likely a pair of Emminence Kappa 15C woofers (same as my k402 MEH). Hopefully it will compare well. I am planning on it being built out of 2 layers of 3/8" bendable plywood, but we might do it out of kerfed plywood. Time will tell as to which is easier, and less expensive to build (I do not want this to get more expensive than a k402 or the only benefit will be size). I might also build a sub to go under each cube to get down low for movies too. It would most likely be a seperate box custom folded horn...with the MINI on top. Sent from my SM-T830 using Tapatalk -
A K-402-Based Full-Range Multiple-Entry Horn
NBPK402 replied to Chris A's topic in Technical/Restorations
You would have to stagger the woofers wouldn't you...which would throw off the position of the woofers behind the port, wouldn't it? I have also thought of this, but I do not know how staggering the woofers would effect the sound. Sent from my SM-T830 using Tapatalk- 1210 replies

I got both Pfizer shots with only a pain in the arm that I got the shot, and a little bit of tiredness. I still wear my mask and practice safe distancing. I will continue to do that until there is no more COVID...regardless of how long that is. Sent from my SM-T830 using Tapatalk

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

Here is some info on the AmpCamp amps...I will be using them for my compression drivers for serious enjoyment. https://www.passdiy.com/project/amplifiers/the-plh-amplifier Sent from my SM-T830 using Tapatalk -

I have not heard of that amp. Have you looked at the AmpCamp DIY amps (Class A)? They should be more than enough power for a k402 compression driver. Sent from my SM-T830 using Tapatalk -
Makes sense, since masks do not care what strain you have and still protect you better than no mask. I saw a report this morning that apparently they have not been testing t cells, and the numbers could be much higher on who is infected. Sent from my SM-T830 using Tapatalk

Just got my 2nd shot, so far fine. What I meant was I am hoping the 3rd and yearly have no side effects. Sent from my SM-T830 using Tapatalk

I get my 2nd in the morning... I hope that if they have a 3rd shot it will be like when I got the 1st one...no side effects. Sent from my SM-T830 using Tapatalk

I think I have the same ones (I have had them for at least 3 years). I also purchased this year a pair of Drop 6xx (Sennheiser 650s made for Drop), and today a pair of KZ ZS 10 PRO EIMs. Sent from my SM-T830 using Tapatalk

Now here is a question... if you get Phizer this year and next year they say you need a booster and Pfizer is not available for you...do you get Moderna? Possible problems with using a different vaccine? Sent from my SM-T830 using Tapatalk

I purchased a LaScala years ago that came with the amp included for Organ use. The one I had looked exactly like a LaScala, but was black. Sent from my SM-T830 using Tapatalk

No...my response was about the poster with the cornwalls. I am building a smaller square k402, in a custom cabinet. Sent from my SM-G985F using Tapatalk- 1210 replies

[mention=62555]Chris[/mention] Would it be better to assemble some wall acoustic treatment panels to make a box around the front of the speaker, and have the mic inside of the acoustic panel box? Sorta like a acoustic panel mini anaholic chamber for tuning your crossover? Sent from my SM-G985F using Tapatalk -
If you need to buy speakers... I would buy used, so you can get better ones for your money. Sent from my SM-T830 using Tapatalk
