This is quite different than the 'White Paper' version. Must be the latest 'revision'. White paper also had a 4 ohm "High Output" Are there any schematics for the ES7500 floating out there? I wish to take the time to say THANK YOU to ALK for sharing and posting these once upon a time. His work lives on even in his absence. I certainly appreciated his past efforts and knowledge sharing. Thank you Al. 😉

Just for S&G's here is a link you may find interesting. I don't know Carl, and I have not duplicated any of his work, so don't shoot the messenger. Some of this thread should look quite familiar to many of you. https://www.avsforum.com/threads/la-seos.1458686/ Carl Huff's conclusion on page 5: Note that the horn is now more controlled. The overall amplitude is flatter and that is something that I simply had not expected to happen. So the question that everybody wants to know the answer to is ... "Does the ported version sound any better than the unported version?" The answer is a qualified, "Yes" but the difference won't set your knickers on fire. the change is subtle. The bass sounds marginally fuller and the midbass sounds less 'crashy' for lack of better words. And finally, "Is it worth the effort to add the ports? " Again I say, "Yes", not because the bass is extended but because the midbass cleans up. Perhaps that is the improvement that people are hearing when they add volume and ports to the Klipsch La Scala. Both the ported and unported versions need to be supplemented by a subwoofer. So which is the better idea to improve an existing pair of Klipsch La Scalas, adding volume and ports or reducing the cabinet volume and leaving it sealed? I'd have to say reducing the volume as it is the easiest improvement and offers similar results. Adding volume and ports is major surgery with only a minor improvement over reducing the cab volume. So there you have it...😁

Thanks! 👍 The direct comparison graph says a lot. I still want to hear it though.

I don't want to hijack this thread, but one other alternative is the "manual' DSP method. I'd only need three additional Chi-Fi amps to cover R/C/L speakers by using the White 4400 Equalizers that I already own for each speaker. Yeah...I know it's not exactly the same...

...I tried some acoustic foam in the doghouse, it KILLS the punch. I'm not totally surprised that this may happen. I mean the frequency sweep captured by Carl Huff clearly shows the response being 'smoothed out' by lowering some peaks while raising some dips. Does the type of foam make a difference or is all that matters is the amount of volume displacement? I don't know. I've debated around and around in my head about going the DSP route. My challenge was/is needing at least nine amplifiers to run L/R and Center 3 way speakers. Then down the road if you upgrade your Home Theater amp, you'll need to find one that provides "pre-amp'" outputs to drive the other nine amplifiers being fed from the DSP unit. Another issue I couldn't address is the probable 'lip sync' that would occur after the signal passes from 'pre amp' to DSP, to amplifier, to speaker while using the home theater. At least this is one of my fears. Not having a DSP unit to test makes it hard to know for certain. In the end, as much as I like the idea of using DSP, using old school crossovers is probably going to be the best solution for me for listening to music and home theater. If I'm missing something, I'd love to be corrected before I lay out cash for more crossover components.

I wish my 'repaired' amp had lasted 3 years. I couldn't justify throwing another $250 plus shipping (over $500 total between two repairs) only to have it blowing fuses again in another week. Don't get me wrong, using the OEM amp would be preferred, but for me, having been burned once, the risk vs. reward wasn't there. The Crowns usually go on sale around Christmas. 'B' stock units are $380 on fleaBay. The Rolls unit is $56. So, pay roughly $440 one time, or roll the dice, and get yours repaired for $250 plus shipping. The risk would be to end up like me and having to pay the $250, plus another $440 ($690 total) after the repaired amp fails and go the Crown route. Understand that I could be in the minority of having the OEM amp fail twice. Another issue is, after paying for the repair, even once, for that same cost you could get a new subwoofer. WOOT has Klipsch R-12SW 12" for $185. Yeah, it does not have the same spec's but...🙄 Muddster, it's a crap shoot either way, and neither option is cheap. How's your luck? There's also this possibility. Good luck!

I plan on trying this soon, just for S&G's if nothing else. I mean it's one of those 5 minute (one hour) jobs. If it works, great... if not, well then it's reversible and the cost to try is less than $20. May even throw some sound deadener mat on the inside of the doghouse walls. (plan to lay it over some low tack shelf liner for easy removal) I just wish I had a decent microphone to take some accurate measurements. I'd welcome others to try and maybe compare notes. I'd have to recalculate the numbers, but I *think* that one piece of the Harbor Freight Anti-Fatigue Foam Mat set, and one of their kneeling pads (wedged between the magnet and the doghouse corner) will provide sufficient volume to reduce the doghouse by one third. I understand Carl Huff used a foam pillow, but the HF options are more convenient for me to try.

DJK, and Carl Huff had some interesting observations and graphs in the post below on the subject. La Scala Mod Project Completed La Scala Mod Project Completed - Technical/Modifications - The Klipsch Audio Community Notably, "Clearly the Klipsch La Scala can be improved by reducing the volume of the sealed enclosure."

Been there, done that. I had mine repaired and it promptly failed again a week later.😡 My solution... Get a Rolls MB15b Promatch 2-Way Stereo Converter, and a Crown XLS1502 Two-channel amplifier. You need the converter to bump up the "line in" signal to a "Pro" level to feed the Crown. (trust me on this). Set the Crown up in 'Bridge' mode, configure the DSP setting on the front panel, and you're pretty much done. Is the DSP as nice as what was built into the Klipsch Amp? Not even close, but the subwoofer itself works great! I also have more confidence in the Crown amp than the Klipsch (which have a dismal track record). BTW, the woofer inside the RT-12d has an 8 ohm impedance, so you can't just connect any 'plate' amp to it. Good luck!

We are about 60 points, give or take, away from a support area in the DOW, and 20 +/- in the S&P. So far I have to give the past two rounds to the grizzly in this MMA bout. Man, has it been ugly...forget the Kung Fu fighting... the bear apparently has Freddy Krueger for a trainer.. It's been over 800 days since the market has had a 10% or greater cleansing. This might be just what the doctor ordered, but that's another 800 points away for the DOW. I hate colonoscopies.

Yeah, that's me. I often think back to these words of prophecy http://wn.com/ross_perot_warning_the_giant_sucking_sound While, this doesn't directly apply to me...(then again maybe it does), but as a nation, I'd say it was dead on. Until there are jobs created in this Country, there is just no way this economy will stand up on its own w/o external support. Once jobs are created, the rest of the crap will take care of itself. jmho Coytee, I owe you a PM...it's coming

I hope I'm not boring you guys with this. I want to make it clear that I'm not an expert, but wish to share items of possible concern. Todays pre-market is up, so we shall see how it closes. S&P 500 Rising wedge or Ascending triangle. There is a difference, though they look very similar. The rising wedge is bearish, while the ascending triangle is bullish, and generally has a much lower angle of attack. http://www.growthstockwire.com/2518/beware-of-the-bearish-rising-wedge Here is the S&P 500 chart. The redlines within the blue channel contain a possible rising wedge. Make no mistake, the charts are not a 100% guarantee that the market will follow past behavior, but as they say, history repeats itself. Here's a conundrum The Dow is still in it's Bull Flag channel, bouncing from side to side. The premarket is up, will it close up and break out of the channel? Will the S&P follow?

I guess it depends upon what time in the business day you placed your order, and when their local Postal pick up time is, but I would think no more than three business days.

What a crazy day in the market. Is it or isn't it.... http://thepatternsite.com/flags.html

Speaking of options, here is an interesting article from one of the better know option guru's. http://www.marketwatch.com/story/monday-sell-off-is-a-warning-sign-2014-01-14?link=mw_story_kiosk The next few days should be very telling.

Coytee...actually I agree with you. That said, one of my biggest fears, and hence my being scared is that I'm ignorant when it comes to option trading. It's a totally different world that requires it's own dictionary! Mind you, I'm still trying to get a good handle on T/A, and have spent years doing so. It's not that I'm opposed to learning option trading. I just haven't found the time to properly do so w/o adopting a gamblers attitude. I have several books on the subject, (McMillan, Cohen, Fontanills) that unfortunately have gone unread There's just never enough time. Maybe after I read all the books I bought on how to get your kids into college for free, I'll get to the option trading books. I have friends that trade options. One made a ton of money...and then gave it all back. I'm talking giving a million bucks back to the street. The guy had been doing so well, he quit his job, stayed home and traded. He traded himself right back into his old job... Actually, almost everyone I know that trades options, with a few exceptions, has a poor track record. The few that have done well, are well disciplined, follow a tried and true system (for them), and only trade a small universe of stocks. They also mostly sell options, which is what most of the T/A books I've read support doing, IF you are going to trade in that world. Here's the kicker, you can't trade options w/ your 401K. Ok, you can if you take the tax hit, move your money into a Roth, and become self directed...(which I may do for other reasons anyway) Other than that, you are, in most cases, limited to your usual small cap, large cap, S&P, bonds...maybe a real estate fund. There are no funds that allow you to go against the market, invest in options, or futures contracts. Like most people, this is the pile of money that I need to protect, and grow the most. And like many, I had a good year last year and want to keep it !!! If the stock market goes south, and interest rates rise...that kills investing in equity funds or bond funds. So what are you left with? Sitting in cash or real estate funds...maybe internationals, but I kind of doubt it. Obviously, my other trading accounts, I'm free to do with as I wish, and so I'm less worried about them. I can trade the SQQQ, no options required! Now that I've kicked over this bucket of worms...I'm all ears on how to pick them back up! Getting back to T/A...I am a little troubled that the VIX doesn't support the market taking a crap, at least not at this time. I can't say the same about some of the indicators on the SQQQ. Just more conflicting data. I'm not 100% convinced the market is going to go south. Last week, I was convinced that a 'bull flag' was forming in the Dow. Who knows, that may still be true. If so, and the market moves north, we will definitely be in Greenspan Country. Now THAT is a scary thought... Oh, Quiet Hollow....EXACTLY!!! Take care everyone. TC

Options scare me. So does shorting the market. I know, it doesn't make any sense...just a mental thing I need to get over. Commodities...I will probably never trade again. Of course things have changed since my last time in that market. Like being able to have a set of real time eyes on the chart and orders. I got burned not once but twice putting in a sell order, via a broker and being assured the orders had been executed...only to get a margin call the next day because said orders failed to be executed on the floor. Tough, expensive lessons those were. Real estate...maybe. Things have yet to turn in my area, which really should be the best time to buy I suppose.

Insurance? As in at the black jack table? That would be great as the cards don't look too good to me at the moment. I hope I'm wrong and the dealer busts. Real estate anyone? Commodities?

Oldtimer, I'm not sure how best to answer your question. I mean you can apply Technical Analysis to almost any time period. From short term day trading, to longer periods including years. Normally, I don't go so far back in time, but that's where the trend lines took me. Think of it as looking at the Big Picture. I wouldn't trade based only a particular pattern w/o verification of a few other indicators, like the MACD, Relative Strength Index or some oscillators. You also need to look at the same chart and indicators in three other adjacent time periods (minutes/tens of minutes/hours/days/weeks/months) whatever the case may be. That said, I would not ignore or turn my back on a stock or index if I spotted a known pattern, just because it didn't have a supporting cast. I may not trade it, but I definitely would not take my eye off of it. It's too soon to tell what this market is going to do. A correction of 1500 points or so would be helpful, but if on the rebound the next peak fails to close higher than our most recent....that would be bad. Very bad. We will definitely have an answer then. I got out of the market back in mid November, and have been waiting for the proper time to re-enter. Yesterday while reviewing the charts, I saw what I posted here, because it un-nerved me. I'm just looking for a little confirmation or opinions, from some that are smarter than me!! Coytee...got your PM. Appreciate it. I plan on getting back with you soon...just have too many other ankle biters to take care of at the moment. Thanks to all. TC

<Sigh>, I know.... I was just hoping someone would tell me that I was reading the tea leaves wrong. When I saw it, my eyes popped out of my head, and my stomach sank. I looked up the formation to confirm my fears. This is what I found for those not in tune w/ T/A. The Broadening top is a relatively rare formation that looks like an inverted triangle. Instead of increasingly narrowing fluctuations in prices, the broadening formation is formed by price swings that are increasingly widening. The difference with the triangle pattern is the change in volume. Volume contracts with the triangle, indicating investor indecision, volume in the broadening top usually expands right along with prices, indicating a volatile emotional market. Broadening Top • The most common of these patterns consists of three successively higher peaks and another line connecting the two lows combine to give the price formation its distinctive pattern. • The combination of wide price swings and increasing volume implies a frenzied market that's out of control, symptoms of market tops rather than bottoms. As a result, these patterns are rarely found at market bottoms. • The signal that the market has topped occurs when prices fall below the lower low. Prices may again test the third peak but usually don't exceed that level. In addition, in some cases, the third peak might not actually exceed the second peak before prices drop and fall below the second low, providing an early indication that the market is topping. • The broadening top is considered complete once this violation of the second low is made. Which would be point # 6, but if we ever reach that point we are in deep, deep shizz. I stole this definition from here http://chart-patterns.netfirms.com/broadtop.htm Nothing is absolute, but if by chance the market breaks out past the top trend line... I'm not sure which scenario would be worse.

Take a look at this chart formation and tell me what it means to you. It's the DOW from 1999 to present. I've got my own opinion, which I'll reserve for the moment. Thanks!

THANKS, appreciate the help. TC

A message below from one of the producers Hello All, For nearly a year I've been working with my Shuttle Friends to produce a tribute to say thank you to our Shuttle Family for all your hard work and dedication to America, and those of us who counted on you... It is done, and posted on Youtube. We are grateful to have been able to support Shuttle... Please accept our "thank you," and share as you will... Much love and all that, Dan

Harbor freight too! Actually, if you built the cable up a bit behind the existing strain relief with some electrical tape and then covered it with h/s it'd probably work as well. You could also split some smaller tube and over lap the wire before you cover it with 1/4" h/s. I just bought a pair and extended the strain relief today ...took 5 minutes.

Make a strain relief boot out of heat shrink. You can fill in any voids between the wire and h/s with silicone.
