[Passive preamps]

"Resistor based passives are ones to avoid."

So a light dependent resistor is bad too?

No, I was referring to conventional resistor preamps. An LDR is a different animal indeed.

Shakey

Why?

These are very nice, many options depending on how diy savvy you want to be. A little pricey but you will never need another attenuator. I could not be happier with mine.

These will be powered by a diy 5 watt SET that is currently driving my kg4s, which sounds good, but I think I can get more out of the first couple watts with higher efficiency.

Absolutely! My LS sounded great with my 3.5 watt amps.

Good luck!

Excellent, that is what I am hoping. Well, I have a pair of kappa 15c on the way, so back to the top hoping someone with a pair of k401s missed this. If not that's ok too. I may end up building a pair of mid horns for this project.

This is how I attached the ground to these RCAs. I soldered directly to the groove cut into the body of the Jack. I used chipquik flux though, which will allow solder to stick to anything! Sorry for the blurry pics but I didn't want to pull my pre all the way out of my rack. Also if you have thick panels you can use brass nuts meant for lamps in the place of the ones that are supplied with the jacks.

I emailed him right away (16min after post), but no response.

I waited awhile, you are probably at the front of a long line. If they ever reply..good luck.

Got a flexible budget?

 

Not really

Do a search on 'JubeScala' and/or the K510.

I have read a little about the 2" CDs and large format horns and while that is probably sonically the best and my wife would probably not mind the way they look, those components would totally drain the diy piggy bank. My goal is to build a pair of la scalas with as many "first step" upgrades or "hacks" as possible. So, heavily reinforced bass bin and the kappa 15c vs k33, ct 125 vs k77 and so on, I would also like to stay passive for now with mostly off the shelf components. Now I am going to make these splits like the LSII so down the road I can continue on the upgrade path. These will be powered by a diy 5 watt SET that is currently driving my kg4s, which sounds good, but I think I can get more out of the first couple watts with higher efficiency.

 

   

Last I knew Klipsch parts will not sell them to you without S/N's of existing speakers.  That said it has been awhile since I have purchased anything from them.

Yeah that's what I ran into.

[WTB pair of k401 horns]

Thanks. Will do. Once I get most of the parts lined out I will start a proper build thread.

[WTB pair of k401 horns]

Thank you, however I am building from scratch....

[WTB pair of k401 horns]

Called again this morning and no dice. I was told if they had them they don't sell items for diy. Which I understand. I said but I own kg4s? But no not quite. I guess I could have come up with a good story, but I'm not really looking to con customer service at klipsch.

So back to square one. K401s anyone?

[WTB pair of k401 horns]

Call back, you reached an idiot in customer service. They use these for current models, they have to have them in warehouse somewhere.

I wondered about that. They guy I spoke with was very nice but didn't seem to know much about the la scala or k horn(though I'm no expert either!) he said I had the right part number but he could not find anything. I even had him go through various model years to hopefully find it that way, but to no avail. When I asked about the LSII midhorn he told me they only sell the top half as a complete assembly (cabinet, tweeter, mid horn and driver, network....the whole thing.....which I found odd, but I didn't want to bug the guy any further.

Is there a part number other than k401 I should be seeking, or someone specific to speak with perhaps. Thanks

If the sale falls through I am interested.

[WTB pair of k401 horns]

The plastic version seem to be everyone's favorite non "aftermarket" option. So I would prefer to start out with them. I originally thought I could just get them from klipsch when I first started to hatch this project. But when I called they no longer stock these. Bummer. I also passed on the pair that was on ebay a few months ago. Oops.

[WTB pair of k401 horns]

I am looking for a pair of k401s for a la scala project. As of now I am planning on using ct-125, pd-5vh, a/4500 and kappa 15c for the build which are all readily available. However the k401s are eluding me. I am hoping one of you has a pair in your collection that you can part with. Thanks for looking, and thanks for all the great heritage threads.
