Yes gang. Collect all your favorite Klipsch action figures: Paul, Valerie, Roy, Jim, and Trey and join them as they battle Amar the Merciless. They make terrific wire supports too. Thebes action figure available 3Q 2020.

40 kHz MHz probably. [edit] I would say that there are plenty of units run by PComputers which will do audio range stuff and have the capacity to store and print waveforms and FFT. Granted they are going to be about 3x what you're talking about. WMcD

Following the wisdom of others above, no bitmap files please, i.e. the ".bmp" extension.

I can't agree with my buddy Thebes' rant about picture file size. I love him anyway of course. People are not exercising the sense that God gave a goose. Modern cameras create huge files and then people think they should post them with no consideration for technical limitations. The 100 kB figure is probably a pretty good example of how small they should be before posting. Maybe a lot less. I've long suggested that anyone open their picture in MS Paint. Big files will fill 10 screens there. All you have to do is resize to something which fills the screen in MS Paint. and no more It is all that the forum will show on anyone's browser screen. Happy New Year. WMcD

I'm with Oldtimer. I believe that putting the sound though a microphone and putting it on the Internet, and then playing back can not possibly reveal the merits of a speaker. OTOH, I'm an ex-New Yorker and Gutenberg's personality is familiar. Yes, Best of New Years everyone. WMcD

Black nail polish. But do test in an inconspicuous spot on the box.

Well, I got into the rant which was basically my retelling of how I figured out some of mysterious explanations. Leading and lagging imply time advance and delay but that is really not the story. ---- I recall in college walking up the hill from the engineering building to the main campus with a good professor of physics. Seems like a charming mentor and student situation, don't ya think? I asked, "How does a bicycle work?" He said, "That is a very complicated question." Then silence. I thought, "He doesn't know either but he doesn't want to admit to it." - - - On impulse response of a device: I just re-listened to Days of Future Past on the Internet. At the end there is a gong sound. So we hear the impulse response of the big cymbal. Not a bell-like response. Sort of multifreq shimmering with decreasing amplitude. What is interesting is that in the opening seconds of the album there is a shimmering sound of increasing magnitude. I think it is a reverse playback of the same. Therefore we get to hear the impulse response reversed in time. End of Rant 2 and Good Night.

FWIW, the Linear X LEAP system manual IIRC has a suggestion on where to assume the source of the sound from a driver. It is the front plate of the magnetic structure which defines the hole in which the voice coil sits. But I think that is a reference, only. The diaphragm is going to be a bit in front or could be a bit behind physically. Or curved to make it both physically behind and ahead. Ugg. - - - FWIW. The driver and the rest are what is called a "causal" system. Whatever we use as an input, the output occurs later in time. That is the real world. We can't make a system which which looks at lottery results on Tuesday and sends it to us on Monday so we can place bets. The sci-fi of time travel paradox is built on this fiction. An impulse input contains all frequencies with the same zero crossing. When we look at the output even at the diaphragm, the output is later in time. The input impulse is smeared out when we measure at the output. We see graphs of that. Similar to a bell ringing though that is a narrow freq. It means that the various frequencies are delayed by different amounts of time. It arises because of the bucket brigade nature of interacting components which store and release energy. Anyway, we can look at the frequency components of the smeared out impulse. We see sinusoids (e.g. sine and cosines are the very same shapes and generally called sinusoids). These are always delayed frequencies. There is no "leading" when compared to the input frequencies in the input pulse. Nothing happens before it is caused in the real world. At best, if output sinusoid B is delayed less than sinusoid A, then it might be said to be leading A, but it is not a matter of the system moving it ahead in time. There is no Delorian here. - - - End of rant.

It's like the red paint that makes Ferraris faster than other cars. (Edit, I removed the apostrophe but I'm still not comfortable with the plural of a trademark.)

I was thinking that the wire maybe subject to scuffing and other physical damage. Perhaps the wire used on outdoors low voltage lighting systems which is made for direct burial would help. Other wires rated for direct burial too. The other issue may be strain at the connection to the amp and speakers. Short lengths of any sort could be brought to stoutly mounted professional Neutrick connectors as shown at Parts Express. I've ever used them but you see the issues. WMcD

In my view, no one has identified a shortcoming in the stock wiring or zip cord. Further no one has advertised their super wire to show it solves any problem. There are just pretty pictures and pseudo-engineering mombo-jumbo. It does look like AQ is talking about problem in other application such as microphones or very long feedwires. Of course twisted pair pair, but not two pair, is widely used there. My guess is that Roy had to bow to the requests of the publicity department and did so as long as there was no harm. WMcD

Prayers are said for your buddy.

I jumped the gun on that one. Checking ebay I see several walnut cabinets of varying designs but fairly close to each other. Marantz are amoung them. Maybe all McIntosh have the metal elements to take the pan-lock system. But the OP's doesn't. WMcD

Certainly McIntosh or a close copy.

FWIW: It seems that one of Crites woofers will fit in an official LaScala but the other one is too big. Guys wind up grinding the edge of the basket to make it fit. So let me suggest you increase the width of the doghouse by 1/8 to 1/4 inch to allow use of aftermarket woofers of unpredictable dimensions. OT: It seems to me that the value of the pound is taking a beating over Brexit and this is driving up cost of importing just about anything. WMcD

Toe-in is recommended.

Let me second Marvel's good comments. I recently bought a used K500. Examined while numounted it sounds like a cast iron skillet when tapping it with a finger nail. But the refrigerator magnet test shows it is not iron. I think aluminum is much easier than iron to machine when creating the threaded hole for the screw-on driver. WMcD

And we don't have to discuss the B side.

The goat, I can't stop laughing. Did they put it in a black dress and blonde wig?

Looks like a K-1000 in this advertisement.

I would use a brush attachment, crevice tool (around the grill), and vacuum to get dust off. Then use "lemon" furniture oil on a Walgreen's facial buff pad on the walnut followed by a paper towel. Be careful not to get the oil on the fabric or black paint. I did some Internet Quartets and this was a good first step. I never got to the next step which would be a varnish. The buff puff can't hurt anything. WMcD

There was a publication by PWK regarding the LaScala in 1965 and I can only think that the birch raw version became available about that time. The LaScala II replaced the LaScala about a decade ago though others here might have better info. The birch raw plywood has a top veneer of birch and therefore it is technically a veneer but not the furniture-type walnut or cherry. The raw birch were, I think, the lowest cost versions -- and not rare at all. They were available in black at some point. Please give us more information on the condition of the cabinet with pictures and also your goals. They will take a light sanding with a sanding block and fine or very fine paper without much of a threat to sanding through the top veneer. Every one will tell you to be careful -- which is always good advice. Lacquer will darken or warm the appearance the least. There are various wipe on "oil" finishes which will give good results but will darken or warm. You must experiment on an incospicuous spot, like the bottom hatch. "Tung" oil is one of them. What is sold as Tung oil deserves a very thoughtful reading of the label. Some is "Tung oil finish" which means it contains some oil from the tung nut but also contains regular varnish. My pet peave. It is too big a subject to discuss the various modern wipe on finishes such as Watco and Minwax poly. WMcD

What you describe might be an Electro Voice T350 tweeter. It is somewhat rare and expensive. Please, what do you mean by 3 way mono? Do you have one speaker running ? I'm a bit concerned that you might be describing running the tweeter (and midrange) without a crossover -- which is dangerous to the tweeter particularly. At the very least you need a capacitor in series with the tweeter. An A type crossover or replacement from Crites is a better minimum. https://www.google.com/search?rlz=1C1GKLB_enUS688US688&sxsrf=ACYBGNQxldxO5zREC9TSBEnsBiq-87KoeA:1571559451960&q=t-350+EV&tbm=isch&source=univ&sa=X&ved=2ahUKEwialoKXs6rlAhUGd6wKHZpOCoUQ7Al6BAgIECQ&biw=1280&bih=579 WMcD

Assuming you have Windows. Open the pix using MS Paint. Use the resize function on the home tab to shrink it. Probably 25% is a good start. Then save the file using a .jpeg format. "save as" You can thus resize it so that it just fills you computer screen or a little smaller. WMcD
