A question of horn priorities...


CANT

Recommended Posts

I've done and read up on many others foyer into the field of upgraded tweeters and in general (as with most horns) it seems big is better...

 

But in a space conscientious world I am left wondering if you apply this to mid-range horns as well, which is the more important upgrade?

 

As in, lets say, if you had to choose between running (think small for now) a K701 with a K100 or a K703 with a K107 which would you choose?

NOT a K700 or a K701, definitely the K703 or better yet the horn from a CF3/4 (I forget the number sorry) which is a one inch entry and is the largest wide band horn Klipsch has released to date, in any home loudspeaker, it very close to the size of a K510 pro horn (which is a 2" entry). If you have a three way design which you want to keep as a three way you can use the K703 as both a mid horn and as a matching tweeter this is a perfect match far better than using a K79 for example. The K703 is a thin wall horn and it does benefit from a layer of Dynamat on its walls.

It's early and my glasses are smudged a bit...but I swear I thought you wrote ....'a K510 porn horn'

 

:o

 

Now that I think of it, it might be a good description.   :ph34r:

 

That said, to CANT, you can be pretty comfortable with what Moray says.  Seems he's been around the block at least 1.34629 times.

 I think you are close to answering my question... let me rephrase it though... remember, I am not as interested in which exact part you would choose, as much as which part you would upgrade (if possible). There is not meant to be a right or wrong answer... just opinions.

 

The 703 works very nicely as a squawker and tweeter horn and can/could be used in either location (partly why I'm using it in my example). In a perfect world, we'll say, you'd use it in both locations and enjoy... but lets say you only have enough room to use it in just one location. Do you feel the horn is better put to use as a tweeter or squawker? I guess the top section of the KLF20/30 is a good example of one of these 2 directions?

well it is the horn Lens that I would upgrade the mid horn driver is fine. So long as you have a four screw style mounting driver you are good to  upgrade to the K703. Does that better answer your question? The K703 is a wide band horn and it is just as good as a mid horn as it is as a tweeter horn lens. I would say it is a better tweeter horn than the horn used on the K79 and a much better mid horn than a K701 is. You can't use a K79 tweeter driver on the K703 horn lens though you would need to buy a new compression driver that has a matching four screw mounting pattern and a one inch exit. Are you considering building new cabinets?

Yes and No. I am considering modifying/building a cabinet but that's not really the only reason I asked the question... I am also just curious in general?

 

I guess if you were to look at the "newer" Klipsch 3-way designs, like the Forte II/Chorus II and KLF20/30, the mid range horn is generally what has been revamped. I just happen to have recently tried out a couple different tweeters on top of a pair of Heresy and was surprised by how much of a difference could be noticed even when the only thing changing was the horn lens (motor/driver staying the same). For instance going from a K76 (stock) to a K74 (KG4 w/ K76 motor) to a K100 (KLF10 w/ K76 motor). It just got me wondering... I hear quite frequently that upgrading the tweeter diaphragm material from phenolic/poly to titanium is generally one of the most noticeable upgrades you can perform but I never here the same for the midrange? I would agree that the first time I ever performed that upgrade it was like night and day but I personally have never replaced any of my midrange diaphragms so I can't personally compare. I have switched between a K55 and a K52 driver assy but I wouldn't say that was as instantly noticeable?

switching from the phenolic mid diaphragm to the ti mid diaphragm is the single biggest improvement you can make in any of the speakers you mentioned. Switching out tweeter diaphragms is very nice but it is only impacting harmonics while the mid handles all fundamentals. It takes them to a level that you simply cannot reach with phenolic. It is all about the mid range and and having ti or Aluminum or Be diaphragms playing all your fundamentals it is a huge step up. So is going to large format drivers you can't ever go back to the distortion of small format drivers after having things so very clean.
