Thanks! [

Boy, and I thought having three Altec 511B horns staring into my chops was a lot of horn!
WOW! Those JBLs are monsters! I'd love to hear those things.
BTW, do both woofers cover the same range, or is the bottom one crossed over lower than the top one? I ask because I'm getting ready to design dual 15" bass bins for my mains.

Ditch the 7's! Ditch the 7's!! LOL
Seriously though, I have not heard the 7's but have heard the smaller ones right below it along with most of the other fairly recent Klipsch lines. Honestly, I have never been to fond of any of them.
Again, I have never heard the Forte' II's
Great advise from someone that's never heard either of the speakers in question.I say LOL's to that.
Laugh all you want, chum... And I see you convienently leave out the part where I say that "I have heard the Forte's and Chorus" (I's and II's no less), not to mention several of the KG line.
Like I said, I have heard everything around those lines other than the two in question. So what?! That's enough for me to give some advise. You're just trying to defend the RF line because you own the entire RF line. No problems with that, it's just MY OPINION.
Besides, it's not like I or anyone else needs to do a lot of convincing since it sounds like wuzzzer almost has his mind made up anyway.
-
I would say just let your ears decide, but try not to make a quick decision. The Fortes were made in '89.
My Cornwalls were made in '79 and a lot of people prefer them over the RF series. Age has nothing to do with it. Just make sure the caps in the networks are up to snuff and you'll be fine.

Again, I have never heard the Forte' II's, but I have heard the Forte's and Chorus and definately preferred the sound of them over the Reference and Senergy line. Obvioulsy, I have heard the Cornwalls as well, and really like them over the others. The old KG line did pretty good as well, but they did lack that midrange "snap" at times (KG5.5, 5.2. 3.2).
All and all, I'd stick with the Forte' II's if it were me. They are the closest thing to the true Heritage line (without the bulk) and are the only Klipsch loudspeakers I have ever really liked.

Hey Dukey!...
"still hard ta beat a 3-way, isn't it ..??"
True, it takes a bit to beat a good 3-way, but I feel I have finally beaten the 3-way Cornwall with my current Cornwall/Altec combo in active, bi-amped 2-way mode. Granted, there's more money, more electronics in the signal path and more time involved, but the end results are great and I would do it over again! [

BTW, it turns out a lot of folks are using the 5751 in place of the 12AX7's.
Yeah, I think the reason for that is mainly because the 12AX7 is such a high-gain tube (MU 100) that it can be a little noisy and even a little bit harsh. This is one of the reasons why I went with the 5751s and why many go with the AT7s and AU7s as a replacement.
-
I'm glad to hear the KT77s and 5751s did the trick for you.
Tell me, did the 5814 do anything for the sound at all?

Chops, It's a Hickok 600A, so he'd be real familiar with it. Thanks for checking with him! It's functioning, but I'm sure needs callibrating.
Oh yeah, he may know a thing or two about that one. LOL
And you're welcome. [

I've never bought any NOS from anyone except Brent Jesse. If he says it's NOS -- it's NOS.
Amen, brother! [

fini,
I'm sure he wouldn't mind. Pretty much, if it has tubes or something to do with tubes, he'll work on it.
What kind is it (brand, model, etc...)? Is it tube based or SS? That way, he can look up the schematic online for it and see what can be done. Don't worry, he can work on either type.
I'll ask him when I get off of work today.

how about a khorn hf section on top of a jub lf?
I don't like the idea.
Just a suggestion, but it might be better generate a few thousand of the composite version of the horn you and PK designed together -- and finish her in the way you guys originally intended. Sell two versions: prettied up and raw birch with the horn just mounted on top with brackets. I would probably make the leap if that horn was thrown into the mix -- I think others might feel the same.
You guys should split the Heritage line and sell two versions of the Klipschorn and LaScala: One with the current/original top section and another with a tractrix horn and better tweeter: "Classic Heritage" and some other name for the updated ones.
And I thought my room was small!!!!

I just have more thing to say...

A very reliable person to deal with.

Still trying to figure out what this old Sylvania is....
BTW, I asked my dad about this tube and he thinks it's some kind of transmitting tube, but he can't say for sure.
How many pins is it and does it have any other markings on it for possible identification?
-
I got a old RCA UY-227 globe that I'm pretty sure is NOS. It appears to test good and strong on the emission tester, anyway.... but that don't say much....
Just to let you and everyone else know, I now have the ability to test tubes. Since my parents have moved back to Florida, I have full access to any of the equipment that my father uses for his tube radio business.
Mike, you are correct in saying that just because the emissions test good doesn't mean that the tube IS good. The only way to tell that is by testing said tube on a tester that does Mutual Conductance.
I have a total of 3 testers at my disposal:
Precision 915 - Emissions/Noise/Microphonics
Sencore MU150 - Emissions/Mutual Conductance
Hickok 600A Mutual ConductanceAnd that doesn't include all of the other test equipment that I'm sure can measure different parameters of tubes.
All 3 of these testers are maintained and calibrated on a regular basis by my father.
Anyway, just thought I'd put that out there for you all! [

Once again, you take what I say out of context, twist it around and try to make me look like an idiot. Tell me, why do you ALWAYS get extremely defensive everytime I make a post in your threads?
And please read again, I DID NOT say anything about "bashing Tenor". That is all you twisting my words around again.
Calling Tenor the "best" is purely an opinion. Personally, I feel that Halcro could and would walk all over Tenor any day of the week.
Sure, I may not be able to afford that type of exodtic equipment, but at least all of my channels work perfectly! LOL
Oh well, enjoy your day. [
] -
I'm not familiar with Tenor, be cool if you could post some pics of it/them??
Tenor amps are quite complex,look at the inards of a classic tube amp,then look inside a Tenor! A world of complexity strikes you,only Tenor's techs should ever touch these.
You know, there IS a reason why a lot of people prefer tube amps with straight forward point-to-point wiring over "complex" designs. Just because one disign is more complex than the other doesn't always mean it's better.
Don't get me wrong, I'm not bashing your amps or anything, just making a statement. [

Ed should chime in about the Cobreflex (for Cornwall anyway). I like the 511b/902 for CW's crossed at +/- 400hz. Both would be an inprovenent to the K-600/ K-55. Not sure that he or I could post a valid comment about replacing a K-400 in Khorns or LaS.
tc
Well as you know, I used the Pyle Pro horn for a while that was supposed to be very similar in sound to the K-400 horns. They still didn't compare to the Altec 511B horns.
The 511B/K55V combo was pretty decent, but the 511B/902-8B combo is much better, smoother, cleaner, more detailed, plus the added bonus of allowing you to go 2-way.

"Maybe I'm not explaining myself, I don't know. What I'm trying to get at is if you have 2 cones distorting instead of just one cone distorting, then the distorsion should be twice as loud, no/yes?!"
Twice, no. You don't get twice as loud when you double drivers... you gain 3dB, and potentially another 3dB from doubling the power handling of the system.
"And I am referring to reaching the limits of the drivers, whether it be one driver or two."
And the point you are missing is when you double the drivers you also have more max signal compared to a single driver. Distortion is measured as a percentage of the signal. You have two drivers distorting at the limit but you also have more total signal. Figure our if the ratio of distortion to signal has changed.... at the limit of one driver vs the limit of two drivers.
And that is saying nothing of using dual driver tricks (which might not physically fit in a horn) of doing something like mounting one driver backwards and feed it inverted phase to cancel some of the mechanical odd order distortion of the drivers themselves. M&K does this for example in their subwoofers.
Shawn
Hi Shawn,
Thanks for clearing that up for me. That's all I wanted to know. I just forgot about there being "more" signal as well.
And as for the M&K subs, that's why I built my sub as a push/pull as well. [
]Again, thanks!

Intresting google read on the 5751. Lower gain (70 vs 100) and "sweeter sound".
Any swap canidates for the 12BH7.
Looks like I'll be buying some of the variants to see how they sound.
I haven't had any experience with the 12BH7 tube. I'm guessing that one is used for the driver tube and the 12AX7 for the preamp section.
My M100SE used 12AX7s for the preamp section which I rolled over to 5751 NOS GE tubes Grey Plates, and the driver tubes were 6SN7s which I found a sweat pair of NOS Raytheon Baldwin Black Plates.
If you look closely, you can see that I was running a quad of KT88s in this bottom pic...
-
BTW, for the 12AX7s, you can roll them out with ECC83 or 5751 tubes. They're a high gain triode. I think the 5751's are a JAN tube (Joint Army Navy), which usually means they are built a little more rugged than the rest.

I spoke with the folks at Cary Audio today while ordering some schematics for the pair of monoblock amps I picked up, and they mentioned that The amp (like most that use el-34's) can use KT-77's. Has anyone one interchanged the EL-34 for the KT-77. A google search turns up that the KT-77 sounds a little tigher than the EL-34.
The amp uses EL-34's, 12AX7, 12BH7. Are there any other swap out oppurtunities other than manufacture's or brand names?
http://forums.klipsch.com/forums/1/815806/ShowThread.aspx#815806
The KT77 is the same thing as a 6CA7, which is a beam tetrode whereas the EL34 is a pentode.
The KT77/6CA7 does provide a fuller, meatier sound than the EL34, more of that "tube" sound you might say.
I just sold my two Quads of 6CA7's a few months back.
I preferred the Vavle Arts over the EH's.
Just as a side note, you may want to contact Cary again and ask them if your amps can run 6550 tubes which are tetrodes. My Consonance M100SE (when I had it) could also run the 6550, KT88 and KT90 and that amp sounded best with the 6550s, with the VA 6CA7s a real close second.

Chopsy .....
Noooooo..... Polite way to say this
ifn' ya wanna Debate these answers
YOU need to start from a Genuine landed technical background....
because what you propose is happening here ....Re: doubled distortion component
is laughable to a first year Engineering student
Well that's all fine and dandy, but doesn't explain anything.
So Dukey, do tell me what's going on then. I'm not trying to start a fight or get into name-calling, I'm just trying to find out information.
Maybe I'm not explaining myself, I don't know. What I'm trying to get at is if you have 2 cones distorting instead of just one cone distorting, then the distorsion should be twice as loud, no/yes?!
And I am referring to reaching the limits of the drivers, whether it be one driver or two.
2 hands clapping is NOT as loud as 2000 hands clapping.
-
Chops,
I don't know if it's the same or less. My understanding from a brief email from Roy was, using 2 drivers (what ever their distortion may be) will mean in this case, 1/2 LESS movement of each driver to obtain the same output. Since the drivers move LESS to get the output, there is less distortion.
Though the specifics of that may not be exact, the general point of it is what I understood him to be saying.
To put another way,
If you have 500 bose 4" drivers, each playing at 50 db's, would you have 50 TOTAL db's of sound in the room, or 25,000 db's?
(I fear that's not apples/apples comparison)
Of course I realise that for a given SPL, but I was referring to when you reach Xmax on the drivers. Xmax is Xmax, it doesn't matter how many drivers there are.
Does that make a little more sence from me? LOL
