  1. I think for the purposes I was using the information derived from the test for it was adequate as I was basically just trying to find the differences between the stock driver and the A55-g in that particular application to satisfy curiosity more than anything and to confirm what I thought I was hearing which was slightly lower output of the A55-g, I would certainly want a more precise set of measurements before altering the crossover or making any changes to the speaker.
  2. Which combo sounds best to you?
  3. These are not my measurements and honestly I was quite surprised by the large dip myself when I first seen this. When I took measurements it was directly at the horn mouth purposely trying to isolate the mid driver-- I used an SPL meter and ran frequency sweeps several times for each driver and I did not experience any big dip like that in fact the A55-g actually played pretty flat from about 530hz-6300hz IIRC compared to the k-61 at around 620hz-6700hz, the a55-g was 2-3 db lower in output across the board. I guess I should invest in some testing equipment I do enough modifications that it would be interesting to get a visual on what I'm hearing with each change. Been looking at the mini-dsp's as well just not sure if I want to open that big can of worms or not.
  4. I measured roughly a 2-3db drop in output with the A55-g compared to the stock k-61 driver, same as the k-52 slightly different horn.
  5. In the case of my Chorus II's I felt the drop in output in that frequency band actually helped to balance the speaker out for me. At lower volumes the bass sounds more "full" as the mid horn did not overpower the bass as it tends to do at least in my room and also at higher volumes where the stock driver / mid horn can get just flat overbearing and shouty the A55-g maintains it composure quite well and stays smooth. I don't know how the lower output of the driver would sound in the KLF-30 never tried it myself but I thought it worked great in the Chorus II. I initially tried the driver in a forte II and personally found the sound of the mid to be too laid back for my taste as the forte mid is already dialed back quite a bit compared to the Chorus.
  6. So in another thread the A55-g was substituted in a Chorus II which has the same stock mid driver as the KLF-30 and measurements were taken. You can see in the graph that output is in fact down a little but not in the area above 6khz:

  8. Beauty is in the eye of the beer-holder or something like that..
  9. Looks like a pro woofer in there judging by the magnet. I thought the pro version had round ports though?
  10. This has been my take on the subject. I have had and still have some 20-30+ year old MDF Klipsch speakers that are like new and sound great, I also have a newer set of Klipsch pro speakers made out of some sort of plywood and they sound fantastic as well.
  11. Are you sure? Spec's don't seem to match up and they don't look the same? freq. response is 1200-20khz min recommended crossover freq. 2200hz. I believe the CW-IV crossover freq. is 800hz on the low end
  12. Which Celestion driver model is it does anyone know? Thanks.
  13. I find it interesting that Klipsch's "spare no expense" $20k speaker set the Palladium P-39 and all other models in that line are made with MDF cabinets-- if BB was really undeniably the best choice for every application you'd think the Palladium design team would have utilized it? p39f_-_Spec_Sheet.pdf
  14. Something tells me that even if the expert builders in the "pro" dept. felt there was a slight degradation in sound quality with BB they'd use it anyway. Do you have literature from pro builders stating sound quality is the main reason for plywood use over MDF or is this just speculation on your part? I know a guy who set up very large pro gear venues and he tells me pro gear is mostly "raw" as everything is EQ'd heavily after it is installed which is why a lot of pro gear does not sound good in the home without some electronic "help" if you will, not plug and play like home systems.
  15. Yes, I agree and admit I'm really no expert here I like to tinker and try new things mostly OEM Klipsch parts swapping from one model to the next as I like to keep things close to authentic as possible in most cases. I share my experiences here not based on math or measurements but by ear from my easy chair and I fully understand that things like my room, things in my room, the equipment I use to power my speakers, the source and quality of my music, type of music I'm listening to, how loud I have it turned up or down how many beers I've had or even the particular mood I'm in at the time all can have a dramatic influence on how I perceive the sum of what is in front of me and how much I enjoy it and even then I know its only for that distinct period in time. When it comes to the k--52 vs the k-55 from what I've been told, from what I've read and just knowing how when and where these were used I believe them to be somewhat interchangeable, look no further than the Cornwall & Heresy 1.5. The k-52 was produced to be a drop in replacement for the k-55 in these two speaker models and then were adapted for use in later models. There are some slight differences I believe due to the size of the drivers in frequency response and sensitivity but they aren't that far off, impedance is roughly the same. Now I know the experts will step in and tell me why I'm wrong and I encourage that thanks..
