I guess I'll just point the speakers directly to the room.
why guess? Better to experiment and chose the position/location which results in the best sound (in your judgment). Such experimentation is very useful as it helps you to hone your listening skills and those skills are what you have to rely upon when you decide to tweak your system or upgrade your components.

I get it, what is the cutoff frequency of the K-61 horn?
I do not know the Fc of the K61 horn but it is lower than a K600/601 due to it's larger mouth size and length. Don't forget many horns are used to below their cut off, consider the K700/701 has been used by Klipsch with a 650 Hz crossover and it is a much smaller horn. Remember also that for best performance the rule of thumb is to cross over an octave above Fc.

The mid horn used in the Chorus 2 is a much more modern horn design compared to a K600/601 (metal and resin) horn(s) it is a hybrid conical throat then a Tractrix flare and it is a larger horn which means it can hold it's polar response down to a lower frequency resulting in improved image, it is the horn which Klipsch designed to replace the K601 after they dropped the Cornwall and replaced it with the Chorus (Chorus used the K601 I think) and the Chorus 2 upgraded to the newer improved horn. Remember the K600/601 is a very old horn design.The mid horn from the KLF20/30 is an even better horn in that it is capable of much wider response it can be used up to 20KHz and it is also much shorter which means you can better align with your woofer and that's a big deal. I hope this helps.

So how do you like your odd KLF20 woofer? What is it? Thanks. In the photo you posted one of your KLF20 has an odd replacement woofer.

looks like there is enough room for a k601 CW II exponential horn to fit between the k-33 woofer and the K701 horn , and since it is not threaded alike the K-600 -it should screw right in , of course one would have to measure ------but it does not look to be impossible --------whereas a k61 Chorus II horn would definitely not fit
it does look like it may well be possible but a trio of horizontal braces below the woofer between the woofer and the mid and again between the mid and the tweeter would be a good plan. There must be better modern horns than the K600 that could fit even a KLF20/30 mid horn would be very much better than a k600/601. Just a thought.

Nothing wrong with Cornwall III , the mids horn is smaller that a CW IV , but worst scenario , you can still add a slightly larger mids horn in the enclosure , The K601 versus the K701 -
I don' think there will be room to add a larger mid horn into a CW3 and if it is a wrap around cabinet like the CW3 yu won't be able to swap out the original baffle for a new one either.

Well a Cornwall3 is a big Heresy3. The CW3 has the k701 mid horn the smallest and oldest horn Klipsch uses. Save you money and buy a CW4 better drivers better (largest) horns. What made the CW special was it larger mid horn and 15" woofer and a CW3 is just a step backwards horn wise. Get the CW4 and enjoy yourself til death.
Big room on the long wall.

RIP Alto; ain't it funny how the night moves with autumn closing in? It's closing in for all of us my friends.

just a comment based upon an observation. Flat wound caps are not a good sounding audio choice as the wind tension is never consistent you are always better off using a round wound cap unless you simply don't have the room to install a round then a flat may be your only option.

It seems odd that they measured one watt at 10 feet instead of the industry standard 3 ft..
pro standard was 10ft don't know if they still use that I am not involved. Bars often set for 95 db at 20 ft from the stage for an average level, any louder than that and you can't hear to make an order or hear what specials they may have.

What do you think about using the A55-G with the Crites G700 midrange horn mounted on a Chrous 2? Any thoughts?
I have not used either so I cannot comment on them. I would be inclined to go the two way direction as Bob Crites did with the Cornscala "D" since I like a two way generally better than a three way. Be careful with a CF3/4 horn with a large driver on it, install a driver shelf or hangar as the horn has very tin walls and can crack if shipped or handled hard. Even the KLF20/30 mid horn will crack if dropped.

with the CF3/4 horn the option to go two way is available provided you use a wide band driver and a two way network. one could modify a CF3/4 network.
further if you wanted to upgrade this as a three way then the K79 tweeter horn could be replaced with a KLF20/30 mid horn (it is also a wide band horn) that way your mid and tweeter diaphragms would be in a much better alignment with each other. I should add that the KLF20/30 mid horn will have a dispersion pattern much more like the CF3/4 horn does which will aid greatly in integration of the two horn at crossover compared to the much smalerl K79 horn lens.

Since you have said you've never measured this, who are you to say what "the truth" is? Or did I miss something?
there are now so many companies who flat out lie that everyone pretty much has jumped on the band wagon. I have not measured them but there has been much discussion on this topic. A LaScala might do 105 db at some peak and justify the number if that is what you call justified. I guess it is probably closer to around 103 at 1KHz., drop down to 140 Hz (and below) and tell me what you measure. Who am I? Nobody, so you can be a somebody and measure one or you can pass and be a nobody too.

I have read that about the pushing more air with 2 10's, and it makes sense although I don't totally understand it all.. I had replaced a pair of RF3 II with the KLF-20, and I still do have those. I liked the sound from RF3, and going to the KLF's took a little while to adapt to.
Good advice though as I have in the past, gone backwards.
The RF3 is a good loudspeaker perhaps you simply prefer a two way over a three way I do. My KLF20 are reconfigured into three driver two ways. A good two way does a lot of things right and you can listen to them closer and you eliminate a crossover section that you no longer have to listen to. It takes better drivers to build a top notch two way that is the reason three ways exist they cost less to make. Wide band drives are not inexpensive to build.

posting a WTB add is simply an invitation for trouble and problem scammers. There are other ways of finding what you want which are much more secure.

The mentioned tec- specs are the offical origins published by Klipsch
take at least 3 db off that technical spec and you will be much closer to the truth.

means you need a very quiet amp. I have not measured but I doubt that a LaScala is 105 db efficient 101 db but not 105 db.
-
do what ever you like but don't sell your KLF20 until all the smoke has settled. Your dual KLF20 tens will push a lot more air than a single twelve inch woofer can no matter what size cabinet. The mid horn in the Forte lll may be nicer than the one in the KLF20 but you may find that you prefer the sound of a ten inch woofer over that of a twelve as they do sound different. Personally I like tens over twelves but fifteen's can sound very good and they launch a larger wave and they push more air. You need to do some listening yourself to find out what you like.

For my 2 channel home theatre, I have a bad room layout (furniture, small area rectangular), with souped up Cornwalls and a Triode TRVSE35 tube amp. Is there any way to get a more "ambient" sound vs. directional from my listening area with the Cornwalls? Does the amp make a difference here at all?
yes with good set up you can improve the spatial qualities of your speakers in your room. your gear is what it is and if it is limited then you do the best you can. A good source is the place to start then work your way toward the amplifier don't forget power cords and cables. most of all enjoy the journey because it's all journey.

Thanks, guess I should have read the first post and not just looked at the picture and the responses, they should turn out to be a nice set of verticals. carry on.

nobody has mentioned (I don't think) but those woofers are not K33's.
New Chorus II Project w/ CF-4 Horn
in Technical/Restorations
Posted
lets say for argument sake that the Fc of the k-61 horn is 500Hz.. One octave above that would be 1000Hz.. This horn is regularly used at 650 - 750Hz. by Klipsch and those speakers are all very well regarded. You need to test for yourself to determine what works best.
Another example, the horn used in the CF3/4 loudspeaker systems is larger than the K-61 horn and with a lower cutoff and yet it is used well above a KHz. in those loudspeakers. There is not a hard and fast rule. I am no longer sure just what your goal here is. What are you considering? What is it you are attempting to achieve?
