Yes and if you google wood k-402 horn you will find things of interest. I have to tell you it is a labor of love to do this and would take considerable time to build and accurate measuring both for a build model and during construction and I would never attempt a project like this over buying it outright from Klipsch or if you get really lucky a second hand set. You are talking a huge investment in time and I doubt highly that you can maintain the exact shape the 402 is so famous for.

Nashville Plywood is it. There are also yards in Birmingham that carry Baltic Birch however they are much more $$ and I don't know if they have 25mm. You will not find the good stuff at Home Depot or Lowes or any other store like that. They will have Chinese birch and it is terrible. US Speaker or Parts Express will have them also and won't be calling them subwoofers which of course they are not. Good 2" drivers are not cheap but there is no substitute.

Well a DB meter and a great set of 34db ear muffs will allow for safe testing. Works for Tanerite too at the front yard gun range. You do have one don't you?

Here's a clue.DE1085TN_8Ω.pdf

Klipsch sells them by the set. No one is going to sell you a single and you are going to be waiting forever.

You have no idea of the prodigious output this thing will have and should go to the low 30's. I smell sawdust but unless you carry out that idle threat to appear you will never know.

Came to a conclusion about unisaws also. To darned much trouble to use and keep things square and these sheets are big and hard to handle on that unisaw with precision. Selling it off and moving to mostly all Festool stuff it looks like.

Well I am going for something capable of much more output and bass than that with great fidelity as well. Time will tell if the experiment will do it but I am pretty sure it will. Oh and by the way it is 25mm Baltic Birch through and though as this is a glued sawdust free shop. In Nashville there are tons of custom speakers being built I guess and 5' x 5' x 25mm runs $48 per sheet with tax. Three sheets will be used for this pair.

OK are you all happy now😁

What plans did you follow?

I never win anything so until windashine mentioned this I had no idea I had finally won something. Now I can tune out Judge Judy when my wife sits there mesmerized by Youtube.

I believe the K-45 is used in the KPT-456 KPT-904LF type bass bin and is capable of 400 watts where the K-48 is capable of 200 watts. I can tell you that a KP-301 or Chorus sounds like a book shelf speaker next to something like the KPT-456 with two 400 watt woofers and a 2" throat horn in there. Ok cool thanks, I'm picking up a pair in a few weeks that I got for a great price. I have owned the version 2 and thought it was outstanding. Never heard the version 1's. The Chorus I's are my favorite vintage speaker. Front ported and can go anywhere and sound the same. Respond really well to recapping and new tweeters with B&C DE10 drivers. I am not a big fan of passives as they get torn up way to often and only work well with a wall or corner behind them. Bass is sharp and crisp and none of that boomy box sound I so dislike with Cornwalls.

For sure. Have you seen these pickup trucks they turn into giant bass bins? 168db and the whole truck is flexing. Women standing in front of open windows look like their hair is being blown by a hurricane. 129 is OK but not epic.

OK the pictures should tell me enough to know if we can do this. If I do determine I can make it, and I see no reason to think I can't, you will need to send me the assembly so I can generate a CAD file for it all. Once I have a good model of this I can make it or others can.

Hey I thought I had deleted this thread and apparently not. Moderator it would be nice if this went away as it is too soon to talk about this.

Since there are a number of projects floating around here lately I thought I would post a teaser of one I am working on. Got the Delta Unisaw Monday and the stack of 8 sheets 25mm Baltic Wednesday and tomorrow starts cutty cutty. Once the first one is built and the bugs worked out I will have more to say. This one will be capable of prodigious output. Dedicated to a source of known trouble and audio discontent in Flint Mi.

OK send the pictures.

The process and materials available have improved a lot.

Which part of the assembly are you trying to duplicate? Do you have a physical part to copy?

I do turn up the pipe organ stuff on occasion. I did build these for that after all.

$2 Dayton 1% tolerance caps work good. Many like Sonicaps here and they will run maybe $6 something each and over there Solens will be available cheap.

Those older Heresy's are the best in my book. Real wood and not MDF and I would not think of trying to use water and oxalic acid stuff on MDF. Look into recapping your crossovers to if that has not been done. It will make a real difference in what you hear.

Yeah I was thinking to mention those but $30,000 6' pieces of wire still won the day for insanity for me. Capacitors are really good at starting pleasant conversations though.

Funny you say that. The bigger my speakers get the more I find my level at 80 to 85db since I want to hear all the detail I can. Poor recordings or lesser speakers and turn it up was the rule for a long time here. Now I do still turn some things up but rarely past 95db. With metal walls and large flat hard surfaces everywhere loud is the enemy of fidelity in my shop.

I guess bottom line for me is there is more BS and gullible people around cables than any other thing in audio.
