That is a very clever idea. cheap easy effective. I still can't believe I got 23 responses to this question

thanks. I have many ideas to work with now. It will be some time before I get to these. Are you the one with the nice grills on the La Scalas? Can you hear a difference with the grill on or off? My electronics knowledge could fit in a matchbox and everyone on this forum seems to be very well versed on this subject. I took a basic class around 1972 so I can tell basic parts from one another but I leave actual construction to a couple of people I know who are very knowledgeable. One is building an amp for me based on Eico ST70 transformers and 6L6 tubes. I milled the chassis out of a piece of aluminum channel and welded two end caps on. Next to the painter's. I went with paint instead of powdercoating because of the much better color selection. So that is where I am at. I got my amp to run dead quiet and sounding the best it ever has. So I finally turned my attention to the speakers, not that they really need it but I am wondering, can they sound even better? The Eico HF87 made such a leap foreward in a few days and now I am satisfied with it.

OK...this seems like the best advice. Go slow and inexpensive and see what happens. I think some grill cloth will slightly soften the mid and high horns and I will be done with that. Replace the caps and enjoy. Is there a ready made grill available or do I have to make my own? You are right about being suspicious of audio claims. I stopped reading stereo magazines years ago. It only took 3 or 4 to realize I had stepped into some deep BS.

I always thought the speaker was a little harsh so , after finally getting the amp dialed in which was a long process, I began to look more closely at the speaker as I have heard this complaint from many different areas. Of horns in general. So I tried the trick of taping some tissue paper across the front of the mid range horn and I believe it was a small improvement. The conclusion is that maybe this horn can be improved. Other than that I am very happy with these speakers. The tissue paper is cheap and effective but doesn't look so good. My room size is the big limitation. Also, from working with these old tube amps, Ive learned that capacitors don't live forever and there have been huge improvements in their design. So...what to do. It sounds like I should leave the horn alone. Perhaps a grill across the front? If anything, maybe replace the capacitors and be done with it and appreciate the speaker. Is replacing capacitors a common operation? Bi amping sounds interesting but something I need to investigate. Bass is not a problem. Speaker Type - LSBR Serial# 13R370 Do you know what year these were made? Thanks everybody for your input, I never expected such a response.

.......but it is a REALLY GOOD BOX! I understand what you are getting at. It is like restoring an old motorcycle and putting in all the modern upgrades like an electronic ignition and a modern carburetor (something that will actually meter fuel correctly), yes you have improved it but in doing so it lost some of its original character. Any ideas on why Klipsch used the k400 horn when there were so many others around? I keep hearing bad things about the horn and I notice that they bring zero dollars on ebay. There seems to be dozens of different horns on ebay. I would like to read some theory on horn building. Are the current Klipsch horns a big improvement over the first ones?

I had not even considered bi-amping. The ALK website considers it a can of worms. How do you connect a second amp? I have two mono Allen 6L6 amps, 20 watts apiece. They sound great. If I am using the Eico as the main amp how do you make all the connections? I am suddenly going far deeper into this project than I ever imagined. Thanks again for all the info

Thanks all. I have a question as to how this forum works. All replys were sent to my email and I answered them straight from my email. Now I notice that my replys were not posted on the forum. Since I want to have it posted on the forum I guess I need to reply via the forum and not through my email. Correct?

New to this forum. Here is a basic intro and some questions. First, I am 57 and I have lived in Seattle for about 15 years. I have had a number of lesser Klipsch speakers and finally settled on a very good pair of La Scalas and a pair of Heresys. The heresys are no match for the La Scalas and are going on the block to pay for some Upgrades for the La Scalas and clear some space in a room way too small for the La Scalas. So I am looking for advice. From reading various things on the internet I was going to buy new and improved horns from fast audio to replace the 400 midrange. Does this seem like a good place to start? After that I am considering replacing the cross overs with ALK universals. Since I am guessing, does this sound like the most bang for the buck? I currently use an Eico HF87 amp with a home made but very good tube preamp. The favorite CD I use for judging any component is an old Les Paul / Chet Atkins recording a double album called "Guitar Monsters". I highly recommend it to any one. Fantastic musicians and very well recorded By the way, I make a drop in adaptor for the RCA inputs on the eico, something I consider essential. Any one looking for such a thing? With this you can use modern cables...but just barely. It is very easy to install and requires no cutting.
