what I am trying to accomplish is for the Heresy's to pick up what the Cornwalls are lacking
I dont think that is going to happen.
I use a pair of heresys (set inside) with cornwalls because I want to generate a wall of sound as opposed to distinctive right and left channels, but the heresys dont "improve" the sound quality of the cornwalls in my humble O -
one additional question for those much more experienced than I... does playing this material put my speakers at risk?
-
UPDATE...
^this is indeed what has happened gary. The sound is CLEARLY audible by using my image one headphones through my pioneer.... it's just that the Klipsch speakers are so good at reproducing, imaging and projecting the source material that what was not audible before is now PAINFULLY clear through the klipsch horn system.
what an eye opener, these speakers are so good, they are also good at reproducing and amplifying bad source materials. it could be the actual disk information, or it could be the way it was copied onto the HD... but at any rate, it IS NOT the speakers fault... whew
My bad folks, sorry about all this balderdash.
how embarrassing.
-
yes... all four speakers seem to do it...the heresys slightly less, but they still do it. Also, I do have that same source musicon my ipod and another computer, the playback is fine on those through both external speakers and headphones. I will have to try it via headphones on the pioneer.
To me it sounds like a blown speaker, but everything else plays wonderfully
-
okay, I made three short videos of about 30 seconds each. the first two illustrate the issue, buzzing/crackling. the third is a control video that is played at about 30% higher volume but suffers NO issues during play back.
Example1 cracking

Example2 cracking

Example3 no cracking at 30% more volume.

again, these sounds appear to be coming from the mids and tweets. perhaps they are trying to play lower frequencies?

home run... the Cornwall has been a marriage made in heaven in my book.

Is there some chance you're playing that sort of music?

It does seem to be that this is happening on music where the production qualities are very high. this happens all the time on my Radiohead collection, but does not happen on my Phillip Glass collection even though BOTH cd's have about the same level of piano and musical projection in the movements where this is occuring. the best thing is to get a video and show you guys what exactly is happening/.
-
thanks... I will do all that today. maybe I will take a video to show the issue.
-
Do you have a computer in the room with the Cornwalls or maybe a laptop?
Here's a pretty cool little function generator program you can load up. Free too
Oh cool... thanks!
-
thanks...
but if it was the wiring, wouldn't it be doing this all the time? this is ONLY on a few albums, and it does it everytime I put those tunes on. the rest of the times I play anything, all speakers work perfectly even at very high levels. I am wondering if these albums are pushing through some type of frequency that is causing these horns to crackle, even though it's the mid and tweet, not the woofer.
-
I am wondering what the issue could be other than bad diaphragms.
On my system, Cornwalls and Heresys, the speakers perform for the most part flawlessly but there are a few specific songs in the list where the horns on all the speakers crackle/buzz like a mother F*cker... so much I think my speakers are blown(maybe they are). this happens are even very moderate levels. If I had to guess, it's mostly the middle horn and partial tweeter(I just upgraded to crites 125's)
HOWEVER, the other 99.9% of the time the speakers perform very well with no sign of issues, even at extreme levels.
is this a horn issue as in going bad, or is there some other issue going on here?

all I can say is NICE

Maybe something in the above links may help you in your decision making.
For instance, wow+flutter and rumble specifications on some turntables are extremely low despite being 50-year-old designs (e.g., Empire 298 rumble <-90dB).
If a brand isn't listed, then I'd personally be leery.

some cool info there. after reading that article, I think I am going to need a twin arm set up for 33's and 78's...

I have done this since 1971, and it took a while and experimentation to get it right. When I discovered the internet about 10 years ago, I too "suffered" from negative comments from many folks on various forums. "Can't be done", "Will sound bad", yadee, yadee, ad nauseum. But, regardless of the nay-sayers, it works if done right, and the difference can be quite amazing.
There were, however, a couple of things that I did learn.
First, in effect what you are doing is creating a horizontal "line" stage, or simply put, using a pair as the "center". No problem, except that as long as the speakers are being run as an A/B pair, you cannot adjust or compensate for volume levels, or use the ability to widen, narrow, deepen or make shallow the sound field you want to create. Thats what the nay sayers are actually complaining about. Without that ability, the "array" simply will not sound better than the main left and right alone, or the centers alone. More on that further. as that's really the key.
Second (and it's a "heresy"... LOL) is that in the array you are creating, the "centers" need to be up off the ground and at about the same height as the midrange and tweeter of the primary pair. Try temporarily putting them up on a couple of el-cheapo (make them yourself...) speaker stands, about 24" tall. That will clear up alot of the issues with the upper mids and highs.
Third, that wall inset in the picture is a giant "bass trap".... As an experiment, at about 85dB SPL (moderate but low enough to hear the distortion, go stand in that area. I would suspect that the bass you do hear is "muddy", and the mids seem "mushy". Get a couple of large thick blankets and hang them on the wall about 1' down from the ceiling, across the wall. You should be pleasantly surprised at the improvement. Start looking for some nice WAF approved thick wall hangings, or decorative acoustic foam absorption/diffusion panels. Parts-express has them.
Lastly, and I hate to say this because it's the costly part of the project, the way to really make it work is to have a second (preferably identical, or at the least a similar model from the same manufacturer) amplifier for the center pair. The second amp is what makes it work properly. You use the primary amp for the main left right speakers and set the general volume level you want. Then.... dial in the second amp with the Heresy's to a volume level that you desire for the sound stage effect that you want. As an example, for vocals, you can set amp #2 to mono, etc.
I use this type of system in the living room (3 pairs of Cornwalls), the master bedroom (Klipschorns and LaScalas), and then..... there's the "Wall of Voodoo" man cave (Klipschorns, Heresy "eXtremes" on top of the K'horns) and Belles as the "centers. Along that wall, there is no equipment; that's on the back wall. And about a 6' center section of the 17' "long" wall is treated with acoustic foam panels to kill the "bad" bass that collects in that area.
It works.... really well, and everyone who has been here (and that's alot of folks from the Klipsch forum, including a former Klipsch employee) can attest to the sound quality and the ability to manipulate the sound stage imaging that I want for any particular music genre.
That being said, you can "get away" with one amp if it's a good programmable AVR, because you can set the center pair with the receiver's programmable area at -3dB. -6dB, etc. to get the effect you want at a standard volume level. That's what I do in the living room and master bedroom as those areas are for DTV, videos on occasion, etc. No need to run multiple amps if 90% of what's being heard is..... the "Soap Channel" or the news, etc.
Awesome... thanks.
I sold off my KLF's that were running as a back pair in surround this weekend, so now I am down to heresy and CW. I really want to find a second pair of CW' for second fronts as you are describing and use or sell those mint condition heresys, but they are so nice to look at
-
that's what I am looking for. under 500 would be stellar. I know an sl1200 can be had in great condition for about 350'ish, but I am willing to spend a little more if I can get something that is a real keeper.
there is a sl1200 mk2 for 350 and a sl1200 mk5 for 500 locally on CL
I have also been tracking some Micro Seiki's that need servicing for fairly reasonable prices
-
are these turntables any good... or are they just junk?
I have played with the ideo of a simple sl1200, but If I can get into something better for about 750'ish, that would be cool.

great discussion so far... I am here to learn for sure.
having done the A-AB-B tests, I can say that I can hear, VERY slightly, more clarity with A only with distinct separation between the right and left sides, with AB the sound is more like a full wall of sound, with a nice forward soundstage. I also think that one set up works well for different types of music, jazz and acoustic music sounds great in two channel and large sound music is great with all four firing.so then, it must be worthless for me to add another set of cornwalls??? i wanted to replace the heresys with a second set of cw's
-
Placement is as such... those CW's are about 20'ish feet apart. What I did have to do was to increase the levels from the CW's channel in order to balance out the Heresys slightly more "shril" sound(specially since you are sitting directly in front of the heresys) and then back down the main volume level on all during playback. the way this integrated receiver works is the B channel is running of the "Front High"terminals.
i'd also think getting the heresys up off the floor about 6-10" would be nice.
-
more "congested" it will sound. Frequencies will be bouncing around the room and colliding with each other, make the clarity, a little more muddy.

I think there maybe a lot of truth to this. my room is about 20x25 and clairity does sound very very slightly better with only the CW's running, but the set up seems more full with all four speakers firing.
but sound stage is way out front and very demensional. I guess four CW's wired the same way might be to much??? :-)
-
thanks...
I guess no one is telling why I can not do it. but i am getting hammered on another forum fro pointing out this set up(which is my current set up)
concerning the watt issue(I am a newbie so please :-), I thought if you wired the speakers on one circuit(two left and two right on the A channel) that would half the output and ohms... but mine are set up on their own independent circuits and output and the same level with either channel switched off, seem equal or similar.
I have not noticed any disadvantage as yet sonically except for a extremely small loss in clarity when running all four as opposed to running just the cornwalls.it seems taboo for some folks so I was wondering if I am being an idiot here :-)
-
can someone please explain to me the technical reasons why this set up should NOT work?
Integrated receiver, with four similar timbre speakers set up in this fashion... A circuit with Cornwalls, and B circuit with Heresys. Now I realize that switching the A and B circuits on and off one could enjoy both speakers independently from each other...
HOWEVER, why is it a bad idea to switch both A and B circuits on simultaneously to listen to 2 channel audio with all four speakers as fronts?
what are the technical reasons?
I have tried this, and I do not see a timing issue, a timbre issue, echo issue... as yet. Am I missing something? would there be a better option for running multiple speaker sets as fronts simultaneously?
thanks -
Mono eh... sell me one for my 78 collection
-
what about the mirroring question... shouldn't they be mirrored?

I just listened to zep III at lunch today while eating lunch. I didnt notice any crackling, but I guess it could be there.
buzzing and crackling from horns... update

I know... it sucks.
the idea of a centralized location, or cloud, from which you can draw your music library's a good one.
It's funny because I use my PS3 for some storage and I rip at the top setting. My album files are from 700-900mb each.
