Minor thread drift: FRZN, in the schematic for the KLF-20 XO it shows a 3-way design, but in a description near the bottom #3 specifies "P.C. board must accept bi-amping." What is the "P.C" board, and how does the schematic, which looks like a single input design, do bi-amping?

He sent photos and we STILL don't know what model they are? Earl speculated this might be a law student. I fully admit I am a skeptic, and this might be legit. However, I would certainly like to see some pics of the rear Klipsch tag, that had a date/time stamp from TODAY.

Considering you do this for a living (or at least to make some $$$) I think that is very cool you would offer your expertise. I gave you a big :emotion-21: for that.

C'mon Mark, you're a smart guy; who has Klipsch speakers but doesn't know what model they are? I smell SPAM cooking. +++ I am selling a used dryer on CL right now. I got an email reply that said "do you still have your ITEM?" (caps mine) I deleted it without even a thought.

Why would you trade your 18 volt system for a 12 volt? I had a 12v kit one time which had a circular saw, but the reciprocating saw in your kit would be so much more handy I would think. I didn't see your deal for $179. It looks like the same thing you got is now $242. http://www.amazon.com/DEWALT-DCK413S2-12-Volt-4-Tool-Combo/dp/B007P0DE8I/ref=sr_1_37?s=power-hand-tools&ie=UTF8&qid=1402631719&sr=1-37

The classless Heat crowd was booing the home team. Ridiculous, this is the finals. The Spurs end this thing at home in the next game.

The Bitumax is relatively expensive, and I think it's used primarily for car applications due to its damping characteristics, so I'm sure its a winner. That's funny you think it looks easy, it looked kind of hard to me, because I don't do scissors well, but I do have finger painting skills(the silicon seal version)! The Silicon seal is cheap, dispensed from a tube, like toothpaste, and is very easy to do. That's a lot closer to my skill level. I think either method, or even the mass loading (clay) would accomplish the same result, which is to make us think we have done something cool to make our speakers sound better. It's very American to get things, like speakers, computers, cars, then immediately start to make changes to them them so they become uniquely ours. The Beach Boys video (below) is very culturally biased to the US, so if you need a translation of the lyrics, ask any American kid my age, which is over 50.

Fellow CF-4 owner here, Mark. I don't have a schematic, but I have a few limited XO pics. What's your project?

When I make mods, I really like to go slow and do some critical listening, making only one change at a time. That resistor mod absolutely sounds like the first thing I'd do, with some A/B comparisons between the modded and stock speakers. But that's just me because I like to experiment and learn. I don't think most people are as obsessive-compulsive about such things as I am.

I had seen that as well, and the author did a really nice video and most certainly excelled at using scissors in elementary school! My horn treatment yielded a similar "knuckle-rap"result , but I have 20 year-old speakers and applying copious amounts of silicon seal was not likely to decrease its value. If you check the various web sites for Klipsch you will find all sorts of strange ways to dampen the horns. I saw one where a guy applied about 2-3 POUNDS of some kind of modeling clay. The bottom line is I really don't think you can hurt the sound by reducing unwanted vibration. In my case, I didn't hear a real-world difference between treated and untreated, but I still believe it was a worthwhile mod. If you decide to go with the silicon seal like I did, but sure to PM me or let me know somehow, and I'll give you some specific tips on what to buy and how to apply it. It takes at least 24 hours per horn, so it is not cost effective for the factory to do that, but I have plenty of time for a cheap mod.

What were you trying to accomplish with the silicone? Minor thread grab: That was me with the silicone. The answer for both me and him are the same, though; there is a harshness in that otherwise wonderful brilliant sound that bothered me like a dog to a dog whistle. I fiddled with some cheap polyfil that finally padded that shrill sound out. I am a very happy camper at the moment. I wouldn't mind trying the resistor mod, but I have a very different (older) speaker the CF-4, and my XO is really packed with stuff on the back of the binding post box.

Your best bet is if you can find an Onk 818 for $500. There is nothing wrong with the Emotiva, but it only has a fraction of the features of the 818 because of what it is, an amplifier, while the 818 is an AVR with tons of codecs and listening modes which greatly affect the overall sound. The 818 has more rated power if you believe manufacturers numbers, and it will bi-amp right out of the box. +++ My guess: The 818 will provide as much power to the 35's as the speakers can handle, bi-amped or not. My other guess is that bi-amping may not give you as much improvement as you might think. Do your own research on bi-amping, there is even a sticky thread here on this forum. After that, let your ears be your guide.

I used clear pure Silicon seal on mine, about 12 oz per driver. There is no question that it deadens the wave guide, according to my yet-to-be-verifed but highly acclaimed "knuckle rap test." I would say it lowers the pitch about 1/3 of an octave. In my highly subjective yet 98.4% accurate "listening test" listening to music, I could not hear any difference at all between my modded tweeter and the stock unit. There is a yellow sticker on the end of the horn's CD which says "63." FYI the compression driver on the left is a DNA-360 and is attached to a 12" SEOS waveguide.

Congratulations on FOURTEEN THOUSAND posts!

What are those things on the inside, of the two sides? And forgive the newb question, but what exactly do you use those particular subs for? Are they for movie theaters?

Game three, won by the Spurs, they lead 2-1. SA was ON FIRE with 71 in the first half. I don't care what the final score was, Miami got their butts kicked in "their house."

The Onkyo TX-NR818 I think has fallen into that $500 price range, used. It is now discontinued but has a ton of features, and it does not have the HDMI board problems that the 616 and under models have. It is still very highly rated, and I think it is better than the newer 828 model that replaced it. FYI I own the 717 and I have nothing but good things to say about it, and for the 1.5 years I have had it has been nothing but reliable. It has 125 wpc vs 135 for the 818, and mine has the lesser Audyssey vs the very highly rated Audyssey MultEQ XT32, which is the main reason most prefer the 818 over the 717. http://www.crutchfield.com/S-e9RMClvsKjt/p_580TXN818/Onkyo-TX-NR818.html There is an entire thread devoted to it on AVS. http://www.avsforum.com/t/1412714/onkyo-tx-nr818-official-owners-thread-discussion/0_50 +++ Edit: I just re-read your post. The Onk does NOT have Zone 2 in digital, I think that is analog only, but I'm not sure. It does have pre-amp out on all channels, and it does have bi-amp. If you use the bi-amp, you can only go to 5.1 processing, but you still can do height/wide channels, even if bi-amped.

Youtube has some DIY fixes for the Onk HDMI board, but I'm not sure which models. "Free" sounds like a pretty good deal for someone who is not afraid to do some soldering. +++ Edit; For instance:

That is the best, most common sense explanation I've ever heard of that phenomenon! Thanks! If that is true, then where is the "sweet spot" for power in a SS amp? I know I tend to associate "clean" SS amp power with larger dedicated amps, but it may not be the "power" but better design which is leading to cleaner power, but that is just an assumption on my part.

I suggest multiple vintage VW Beetles placed strategically around the shop can help with the resonance breakup and give you a smoother sound. One is not enough.

When I read the opening post and saw that husk, my first thought was "where will he EVER find parts to fit those things???" Then the next three posts were from guys with parts for those things!!! What a great site this is.

Great game 2 tonight, it could have gone either way. Heat and Spurs now tied 1-1. Coach rested Labron appropriately, the temp was down about 12 degrees from game one, and Labron was around for the finish. I thought the Spurs actually played better than in game 1, the only difference for them this time is they did not have the greatest 4th quarter in NBA playoff history like they did in game 1. These surely look like the best two teams in the NBA. This will probably go 7 games.

I don't want the realism of live music, I want my system to sound better than that. Your point is well taken, and I agree, I want a piano to sound like a piano, and I want a sax to sound like a sax. But there are two points I'd like to address. First, with rare exception (like violin quartets) you don't listen to live music in its un-plugged form, you listen to it through the sound system. Everything is mic'd these days, including drums and cymbals. I know what the attack, sustain and decay of a ride cymbal sounds like, but frankly, it is articulated better when mic'd. Second, some listening experiences like symphony orchestras sound BETTER than live through sound systems. When sitting 100-200 feet away from an orchestra, everything blends together. You don't hear the nuances of a trumpet playing next to a flugal horn, or the real chest cavity shaking resonance that a tuba makes when you are standing in front of it. I love bringing that sound closer to the audience, and hearing it the way the conductor probably does. You don't get those things live, but you can get them that through a good recording on good playback equipment. It's better than live! (but not better than being ON the stage sitting with the musicians. )

Or you can just sell those huge ugly things to me so I have 4. I'll pick them up tomorrow. LOL! But why would you want them, when his wife has apparently already stated they are so ugly, they don't even match the decor in the garage, where she probably never ever goes!

I refinished some Klipsch CF-4's recently, which included sanding out some water rings, and to be honest I really enjoyed the sanding and staining by hand. If I were closer (I think Chicago is about 10 hours from me) I'd take them because it looks like a cool project. GLWYS
