The initial measurements were for singlets (one speaker treated vs. one speaker native), not a combined measurement of the treated pair. For the higher register, I think my measurements were tainted by reflections in my room, rather than it originating from the speakers perse. I've since repositioned the Heresy's further away from the 'back wall' so as not to be equidistant from the side wall. Also, the speakers were raised until they became 100% pleasing to my ears, as any loss to the ported/lower register was more than compensated by my KEF92 sub. Some other changes included changing my cables to HiFi OFC 10AWG and adding GIK acoustical boards to certain parts of my listening room to remove any prior hotspots. I'm running the Heresy's with my Cambridge Audio EVO-150 + CD Transport. As mentioned before, I heard zero change/difference in either the bass or tweeter sound after applying the damping materials. However, I immediately noticed a positive change in the midhorns. There was a prior hint of 'hollowness' which has all but disappeared. This was most notable when playing certain instruments such as the Theorbo or Claviorganum. Some of their notes sounded as if they were routed through a paper tube but now their tone is consistent throughout their scale. The change was enough for me to encourage Klipsch with this post to keep testing different materials (or thicknesses) used for their waveguides as a possible Series-V improvement. I'm guessing if you are updating/restoring an earlier heritage series, the above changes would have a more positive/noticeable effect. In the end, it is extremely difficult for me to explain in words what I'm hearing in person, as any evidence (measurements) of what actually changed seems nominal at best. I guess this is a true testament to the incredible design of what our ears and brain can monitor, decipher, and interpret in real-time.

Jive Talkin, Thanks again for your recommendation. In the past, I've tried finishing waxes by Minwax, Briwax, and Howard's feed-n-wax, though I would not recommend these products to anyone, let alone for a Klipsch speaker, as their performance was less than stellar when applied to various furniture projects of mine (ranging from cherry to walnut). Either way, I received the container of Renaissance Wax today and applied some to an inconspicuous part of my speaker (its underbelly, which is veneered). The end result looks absolutely amazing, and I was able to finish both speakers in just minutes. Again, I am very pleased with the end result; specifically the hand-feel + semi-satin finish that the Renaissance Wax produces after a quick/light buffing. The only problem I experienced when purchasing a 200ML container was that only a fraction of this product was actually used. Like you said, "a little goes a long way". I also tested it on some hairline scratches on one of my walnut credenza as the scratches disappeared on contact, so I guess this will be my next/quick project to complete. My only curiosity is how the finish will hold up over the long haul, but if this is a go-to product for museums, I'm guessing that it will perform well over the long haul (without any need for reapplication). Cheers,

Thanks for the tip as I never heard about this wax/brand before. So far, I'm only seeing very high marks for this product + the YouTube reviews seem to be equally as positive. Just in case, I'm going to test-try it on some of my smaller/walnut pieces first before I consider using the Renaissance Wax for my speakers.

For the walnut veneers, it looks like my speakers have no applied finish (i.e., Varathane, Polyurethane, Varnish, Tung Oil, etc.). I don't know if this is the norm or something that Klipsch expects the 'end consumer' to apply or to avoid in its entirety. I see an old post back in 2010 of someone trying to restore their damaged veneers, but nothing about any recommended finish for newer speakers. Thoughts?

After hours of listening to my treated speaker, I decided to mod (i.e., damp or dampen) its partner and apply DSP afterward. My personal and subjective verdict is that I hear no difference between the treated vs. untreated tweeter or bass drivers. However, there is a noticeable difference with the mid-horns, especially when I play music that spans its entire frequency range. As one who owns and plays various instruments from the baroque era, the Heresy twins are now projecting the same tonal quality, timbre, and 3D imaging that I find when playing the exact same "real life" instruments (i.e., alto and soprano blockflutes, 4xchoir 2-manual concert harpsichord, and 1xchoir virginal) that reside in the same room. Very impressive, especially when coupled with my KEF KF92, but it only makes me wonder what magic lurks behind Klipsch's larger brethren within the same heritage line, or how much more my Heresy twins will shine if I relocate them to my great room with hardwood floors.

Here is the actual Mdat files (L & R) from REW, using *.RAR (instead of *.ZIP); since I couldn't upload the files under the < 2MB posting limit. Some final comments: The nice thing with this test is that the dampening material comes off as easily as they went on, depending on whether the desired results are obtained (or not). This is to confirm nothing else was added to the speaker case, port, etc. I'm guessing that there's another variable I cannot test, i.e., the placebo effect of the changes I made. What I see in the data is extremely difficult for me to discern/hear with my ear(s), especially when I listen to each L vs. R channel on its own. On that note, perhaps I should get my hearing checked too, left vs. right ear, as that too may have skewed any subjective opinions to boot 😉 If folks are interested in seeing the installed Dynamat Extreme sheets on the drivers, just let me know, and I'll post these pics to this thread. Thnx L&R_H-IV_MDat_REW.rar

Applied Dynamat Extreme to the stamped-steel woofer cage, mid-horn and tweeter. I can honestly say that the two plastic horns + large metal basket no longer "ring" when tapped on, but then again, I don't make it a habit of tapping on either when playing music via. these beautiful Heresy IVs. I may treat the right speaker or just remove what was done to the left, as the Dynamat cleanly comes off the metal and plastic with no issue, though its not going anywhere if left undisturbed. Either way, I measured the treated Left speaker (red) to its au naturel Right (green) using REW, so folks can make up their own mind, rather than hear any subjective 👍or 👎 from me. Printscreens are posted here. REW MDAT files will be posted next (due to their file size). Cheers,
