pwcpwc Posted November 23, 2011 Share Posted November 23, 2011 Just wanted to begin this post by acknowledging the warm welcome I received from the forum and thank all of you that contributed to the great data presented. Additionally, I now have a newfound friend that is currently sacraficing to serve our great country in Lancaster, CA. Thank you for your service Dandoyan! He is also planning to go above and beyond (before a 20+ hour drive to Texas) to provide me with an in-house audition of a pair of out of the box 2011 K-horns. How am I supposted to sleep at night? The tubes will glow, the vinyl will spin, and the steaks will sizzle... I will post shortly after his visit. Keeping in mind my end goal is the best sound available for under $2,500.00 and based on the responses I received to question #1 and my subsequent investigation, I am now confident that I can provide acceptable DIY cosmetic reconditioning of whatever set of K-horns that I decide on. In researching the previous posts and comments on this site as well as others I have come to the conclusion that with the exception of some structural integrity and quality control issues that were noted on some sets that were manufactured in the 80’s the overall consensus is that the sound quality has improved incrementally with each subsequent model. This is not to say that there are dramatic differences (perhaps there are), but that the small changes do make small differences. On to Question #2: If you were to strip the electronic components out of a 2011 k-horn and install them in older models (assuming correct installation) from each decade since the 40’s could one expect to achieve similar sonic performance from each speaker? If the answer is yes my mountain just became easier to climb. Don’t bother reading the remainder of this question. 2b.If the answer is no, am I to assume that there was a structural change, or series of changes over the years, which also had an impact on the sonic performance of the speaker. 2c. If there were changes, were they limited to additions to the existing structures (for instance the addition of closed backs) or, did Klipsch also employ fundamental changes to the internal design / dimensions and /or the type/quality of the materials that were used in construction in order to impact the sonic signature? Looking forward to the responces… Quote Link to comment Share on other sites More sharing options...
Don Richard Posted November 23, 2011 Share Posted November 23, 2011 The Khorn bass bin has remained remarkably constant since the 60s, with minor changes such as thicker and sometimes different materials of construction in places. The basic dimensions that define the horn path are the same. I have not heard new factory Khorns yet but differences in sound with current drivers and horns installed in earlier bass horns would be small or maybe undetectable.

pwcpwc Posted November 23, 2011 Author Share Posted November 23, 2011 Music to my ears Gentlemen! Don, do you know at which point in the 60's this change was made? Quote Link to comment Share on other sites More sharing options...
Don Richard Posted November 23, 2011 Share Posted November 23, 2011 About 1963. The throat was changed from 6 X 13.5 in. to 3 X 13.5 in. If you have an earlier bass bin a motorboard change to one with a 3 in. throat is all you will have to do. Not sure but a splitter wedge in the throat may also be needed.
