heli, I am not as diplomatic as my friend Mike. To compare the 402/TAD to any other horn/driver without using a balancing network, either passive or active, designed for each is ridiculous. Sorry for being so blunt but it is meaningless! rigma

No, I am old enough that I don't have to go on the photo excursions anymore..LOL

He tells my all the time he would love to hear my current system. He lives about 7 hrs. away & is not able to make the trip. Last time he was here I just had the Khorns so he never has heard the Jubilee's rigma

Thanks guys, I had actually forgot about this article. It was cool reading it again... So many memories! rigma

Last part.

4th part. I have the Fisher amp in this photo and it still sounds great!

I think I got this affliction naturally. My wife, Beck, was digging through old stuff today and found this. This is an article posted about my dad in the local newspaper in Aug., 1972. My dad built the first speaker, based on Klipsch plans, somewhere around 1962 when I was about 10 yrs. old. I remember so well him building the speakers and several Heathkit and Fisher tube amp kits. I grew up listening to them and was doomed to never being satisfied with less. He is now 86 and still has both speakers plus all his LPs. My dad was a chemical engineer, inventor, photographer and music nut!... sorta like me LOL, except I went the mechanical vs. chemical route. We still talk about Klipsch, tube amps and Jazz regularly. rigma

So sorry to hear this Dean. I am sending you a PM. rigma

The Radio Shack meter needs to have the below correction added to there readings. Hz Correction 10 20.5 12.5 16.5 16 11.5 20 7.5 25 5 31.5 3 40 2.5 50 1.5 63 1.5 80 1.5

This is the issue...even on the "4 Ohm" tap, SETs, with typically low forward loop gain that precludes use of negative feedback to lower its output impedance, have too high output impedance in order to not affect speaker FR. Even the F3 affects Khorn output at 1 Ohm output impedance, if we are to take fender bender at his word (...which I do...). The input impedance complex plane plots correspond one-to-one with his symptomatic complaints about the F3 paired to Khorns. One easy fix is to simply EQ these two regions down, but that doesn't completely erase the issues of low input impedance speakers being driven by high output impedance amplifiers. In rigma's case, the TADs that he uses are essentially a minimum of 11 Ohms, rising to ~27 Ohms maximum in the operating band. I do not know the combined input impedance characteristics of his passive networks + the Jubs, however: my guess is that the combined curve is probably more than 8 Ohms minimum up and down the audible frequency band (nominally 20 Hz-17KHz for us more mature folks). Chris My passives also have LF & HF Zobels.

One of my 300B tubes died one month after I installed these monoblocks. May be the issue is the designer/manufacturer. This is hard to believe, however, that they were that bad. Another issue: the amps had about 2.5 dB gain differential right out of the box. I find that hard to believe, too. This is crazy. By the way Marion, what is the output impedance of your 300B monoblocks? I assume that you're using them with your now-famous Jub passive crossovers to drive your fronts. Chris Yes, I use them to drive the front Jubilees through the custom passives. Sorry, I don't remember what the exact output impedance is but a quick calculation shows 1.58 ohm with the 4 ohm tap. They have Magnaquest FS-030 output trannies. rigma

All I can say is that I have been listening to Khorns since 1965 and now Jubilees and have been through many tube and SS amps. For the past 5 years I have been using 300B SET that I built using premium components and it is by far the best I have heard, even at loud levels. Cask the draw backs you describe are not happening with my system. I don't have an explanation as to why your experience was so different than mine. By the way I have had zero maintenance problems in 5 years, not even a tube. rigma

I have a XPA-5 for sale in the Garage section http://community.klipsch.com/forums/t/159117.aspx

Any update on this project?

You should consider a 300B or 2A3 SET amp for the 402. I use the 300B and Mike Beasley uses the 2A3, we both have the TADs, and they both sound wonderful. rigma

Or you could use KPT-200... I have plenty of them I would sell...Pick up only in Nashville..$150ea if 10 are bought.

These are my favorites and very reasonably priced. They have a screw but I solder mine. http://www.newark.com/deltron-emcon/584-0500/banana-plug-10a-screw-red/dp/45M6912?Ntt=45M6912 http://www.newark.com/deltron-emcon/584-0100/banana-plug-10a-screw-black/dp/45M6911?Ntt=45M6911 rigma

I bought (3) of the "new design" Jubilee bass bins and the buid quality was very good, no issues at all. Also the (2) 402 horns I bought several years ago were very good, no flaws I can see, finish or otherwise. I also think the 402 sitting on the Jubilee bass bin looks just right, even the wife thinks so! Just plug the screw holes around the perimerter with black scwews or plugs. I still say the 402 is the best HF horn I have ever heard. rigma

I looked at the Uline site and can't determine which product you guys are using. Do you have a part number, descripition, or link. Thanks in advance for your help. rigma

In all due respect Josh, his post on page 1 including a link to his website is promoting anyway you look at it. Klipsch has worked for 60 years and built a faithful following. To come hear and try to take advantage of their work for personal gain is stealing imo, and no different than any other common thief. rigma

Does anyone else not think it is so wrong for someone to copy a companies product then try to sell it on that companies forum? It is a shame the world has come to the point that some people will do anything for a buck no matter how unethical. rigma
