Gary, For local dealers, by all means talk to JS Audio in Bethesda, (301) 656-7020. Good store, the one I use for analog. A fellow name of Mark is supposed to be the best one to discuss it with. They ship from California, take about a week. Larry

If so, and the woofer is capturing the the EMI (it's not RFI) waves, it should keep humming when you remove the wires. But, if the network is capturing the EMI waves, then it seems that removing the connection would eliminate the hum. Isn't that what happened here? Doesn't that mean that the network is the culprit? How did you move the network away from the speaker? Offhand (I've never done it), it seems to me you would have to unfasten the plywood block with the network and use added speaker wire to relocate it several feet away from the speaker, while the speaker stays in the corner. Anyone else? Larry

In the thread on this subject under Technical Questions, a couple of folks thought the crossover coils could be picking up the EMI. Someone recommended that you move the network away from the speaker to see if that eliminates the hum. Larry

I really like the cool yellow string that makes everything go! Here is another work of art:

That's totally great, HornEd! My very best to the two of you. Larry

---------------- I am having second thoughts and I am really souring to the idea of going to Indy now. ---------------- Or, maybe some need to meet in person and get out of the road-rage mode.

Of course not!! It's an open invitation to share the joy with us! Remember, I suggested you give'em a listen, too.

Hmmm ... seems very unlikely, but let me think on it. Not very soon, though, since I have an injured foot. Maybe some new/different LPs will help tide me (and Gary) over! Larry

Wow, Fini! The California setting sounds totally beautiful, and THAT's where I'd really like to see it. However, I'll check it out before it leaves D.C. How close are you to HornEd's Shangri-La? Thanks for thinking of us. You've gotta a lot of interests! Larry

I am very sorry for your mother and what you and her loved ones are going through. My thoughts are very much with you. Larry

IOW, there are 6 notches which I assume equate to .5 grams x 6 to get to 3 grams (max setting). Is .5 closer to the front or back. I'm assuming front. ---------------- I think the 0.5 setting would be the closest ("innermost")notch to the arm pivot, because it would give the least sideward pull. That's the way it is on my tonearm. Notches further away would be for heavier tracking forces. It's possible, though, that the first notch is for 1.0.

Do you have any window or door moldings that keeps them from sliding all the way into the corner? That might require some extra work either to make them slide back in, or build out the wall to form a flat surface for the bass horn's last stage to function at its best. Larry

I did run wires to my cornwalls upstairs and as good as the scott sounds, the MkIII/BB combo is just amazing... Great review Dave. ---------------- Gary, I was as very puzzled as you were, and had/have no idea why the differences. It might take difficult equipment shifting to narrow it down. Did you run wires from your Scott down to your Altecs, to see if TT and cart differences might be part of it? It feels a bit like the Garrott/Technics combo might not be as forgiving of LP differences as your Thorens and Shure. I agree: highly professional, thorough review, Dave. Larry

The speaker is on air without any connection and still make that buzz noise. ---------------- Are you saying that without the speaker cable connected to the speaker (or to the amp?), you still hear a buzz coming from the speaker? In other words, the speaker alone with nothing connected is making a buzzing sound when within 5 feet of that corner? WOW! Thanks for the photo, BTW. I had pictured something completely different. The corner as-is is not properly shaped anyway (with that bump-out). I'd seriously consider a false wall using shielding material (if AC wires end up being the culprit). Also, consider asking the building owner (or builder) about that corner. Talk to your local building department, as they may have the plans for that building, or be able to point you in the right direction. An inspector might be able to come over and give an opinion, too. Talk to your neighbors, see if they have similar problems. Does the building have a manager or superintendant? Snoop around the basement or attic to see if you can figure out what's in there. ---------------- I don't have anything to add to the others, suggestion-wise, but that's gotta be one HELL of an electromagnetic field! I've had a lower level hum problem with a variac, which I understand is a sort of transformer, and, yes, it induced audible hum in the woofer and squawker without any speaker cables attached! The speakers probably pick up the field directly via the voice coil. The horns' efficiency apparently causes the hum to be audible; I'd guess nearly all others' speakers would not be efficient enough to make the hum audible. I've had many a power cable running behind and next to my K-horns without a trace of hum, so I think it has to be a lot stronger field than from simple 110-volt lines. I've heard that shielding for RF is different from that for EM -- aluminum vs. iron or steel, respectively. I hope the EM field can be stopped by a wall shield, and not travel around it. Larry

My 58 khorn style d came with the jensen 33j which has plenty of low bass Not lacking at all. I like the jensen khorn sound. ---------------- Tom, I wonder if that means you could mount your Jensens directly to your 6" X 13"-hole woofer panels and bypass the mounting boards altogether? It sounds like Jensens found their way into these K-horns while the factory was trying to make new woofers work with inserts and 3" high slots. You can fill in drilled holes if you try that out and want to reverse course. Larry

There's also a separate "Members Only" forum below Odds and Mods, apparently locked out for non-members, and for discussing the trip. It's been very inactive, though. Maybe it will heat up soon.

I was under the impression that Klipsch used the 6 x 13 slot on the early units with the Stephens Tru-Sonic driver. Having now seen the 3" motorboard mounted against the 6" cabinet, I'm wondering if this was the setup on the Stephens also. Maybe khorn58 will drop in and lend a hand. He has had more of the really old units than anybody I know of. I might round up a a piece of real thin plywood like 1/4" or so, cut the 3 x 13 slot in it and just sandwich it in between the driver and the cabinet. it would come pretty close to what you did. I don't think I'm up for trying to patch down the size of the slot. Or I might just try running it with the 6 x 13" slot and mounting the driver directly to the cabinet like you did. ---------------- Tom, How you attack this will be interesting. All your ideas sound like they have potential, including the thin mounting board with the 13" X 3" slot. You might seek advice from Klipsch about whether my added compression with the mounting board was only because of the longer (1-inch-thick) passage with the motorboard plus mounting board. Since your motorboard passage is 6" high, you would only have a half-inch-thick passageway, tho' with added steps outward soon after that. If those things don't do much, I have a feeling you should try a K33-E, since that's the woof K-horns ended up with, and it and the 13" X 3" slot are designed for each other. I have a spare K33-E, but just injured my foot and can't get it to you very quickly unless someone helps. I also have a good 15WK, whose discontinuation seems to have started all this messing around with the bass throat, but it might not sound good in a K-horn with a network not designed for it. Good luck! I am NOT either an expert! Larry

Tom, that's wild and very interesting! I'm really pleased that my own "adventure" stiumlated your look-see. I myself could not possibly guess what the effects would be of changing any one, or any combination, of the unusual Jensens, wierd inserts, and 6" X 13" slot. Your bass fall-off means something's gotta be changed! Hopefully some of the real experts on the forum can jump in here. Can you glue in plywood strips to narrow the slot to 3"? I suggest you call Mark Kauffman at Klipsch. I'll e-mail you his number. Larry

---------------- I have a very faint buzz (not hum) through my altecs that you can hear only with your ear up to the speaker.... ---------------- One more thing, Gary, in my personal experience: the airborne RFI I had -- the intermittent appearance of faint radio transmissions and buzzes -- varied as I moved toward and away from the preamp, apparently because I was becoming part of the antenna system for the airborne RF landing on/in the preamp! I was told this was typical. I'll bet your hum/buzz isn't affected that way. Unfortunately, the Cardas caps didn't help that a bit. Larry

---------------- ---------------- Larry, Next time you're over, we should do some tinfoil tweaks. Any recommendations on brand? Reynolds OK? Shiny side in or out? Actually, I have no idea what RFI or EMI sounds like either. Have you ever heard either of these acronyms coming out of my speakers? ---------------- No. It's supposed to be a picking up of radio transmissions or a raspy buzz, rather than, say, hum. I would hear faint radio or TV broadcasts or ham radio-like transmissions. My higher MC phono gain is more likely to pick that up than your mere MM cart input, so I doubt you have a problem. I've been told that aluminum is suitable for blocking RF, again unlike hum. Larry

I'm going -- my plane and motel reservations are set, plus a rental car -- it's a looong way from the airport to Klipsch and the Comfort Inn. My plane arrives at 1:44 p.m. on the 11th. Gary, I'm saving a place in the car for you. Larry
