    New Klipschorn AK6 coming out?

    Actually, the K771 appears to also be used in the new La Sacala so there is that... it would only be a drop in for speakers like the CWII or CWIII with a K107/K79/K75 but would require attenuation. Could be worth it though?

    New Klipschorn AK6 coming out?

    I am VERY interested in the adapter plate/B&C driver combo used in the K771 assembly! The DE5/DE7 this appears to be based on isn't a terribly expensive driver at retail so it makes me wonder if they might not switch over the rest of the Heritage line? They all began with the K77 after all.

    Klipsch KLF-10 CROSSOVERS

    I can't comment on the cab reconstruction portion but crossover wise I would just replace the 2ohm resistor, 1.75uF (1.8uF) cap & 6uF (6.2uF) cap on the HF side and call it good? If you can fit it maybe the 8uf (8.2uF) on the LF side? I've never noticed all that much difference when messing around with inductors unless the OEM are of an incredibly poor quality. I would also suggest doing something with the tweeter. Bare minimum replace the stock poly diaphragm with titanium (cheap option)... if you can, what I would really suggest is finding a pair of K703 horns (ebay) that were used in the KLF20/30 & CF2 and buying a pair of Selenium D202Ti drivers. I personally prefer the K703/D202Ti option in the few instances where I've been able to compare the 2. Example: I am currently running the aforementioned horn/driver combo with a single K28E Heresy III woofer and have a pair of K100Ti hanging out in my garage somewhere.

    KPT N2 Crossover Question

    Ok... well I ended up answering my own initial question but I am still curious about the other variation... It would appear that the 902, 310, 325, 942 & 904 are all built on the same board or where when this piece was made. Kinda surprised by how basic it is?!
  5. I'm going to edit this and open it up a bit... I am mostly interested in the smaller KPT-310-M/KPT-902-M but they aren't mentioned/talked about a whole lot so if you have any of the KPT mono speakers (KPT-310, KPT-325, KPT-902, KPT-904, etc.) and it isn't too much of a bother, could you possibly take a couple pictures of the crossover for me? Top and bottom. I am trying to compare the general architecture of the networks in these models. Thanks,
  6. I was very close to picking these up but after speaking with the seller, I found out that crossovers were not included in the sale price... The price is also back up to $1199 as well

    forte II w/ A-55G Mids?

    I would absolutely agree that the switch to the Heppner driver appears to have happened as a cost cutting measure? The Heresy and Cornwall do not command the same $$$ as the La Scala or Klipschorn so keeping the cost down would definitely help them stay competitive in the market place. The K52 is also a VERY good driver, so I do not consider this change a degradation of quality. It is important to remember that the move to the Heppner driver came with some important changes to the network (E2 & B3). Yes, the K55 has better response below 600hz and you can here that difference which means that the way that driver integrates with the woofer is different. This is not just an SPL issue. A lot of those older networks were deceptively simple but that does not mean that they were just thrown together without careful consideration of their implementation.

    Were you a part of the development team for this driver? If you were then I feel like that should be noted as it could present a potential bias. If you weren't then I'm not sure how you can speak with such certainty about the time and/or money that went into the development of the driver? I should clarify that it's not that I believe a product like this doesn't take time and money, I know for a fact that is does but I do feel that the numbers are stated in a way to express or imbue a sense of quality. Ad speak. John Allen also very much owns/runs a company that produces a line of Klipsch Heritage knock offs so producing his own driver could absolutely save him some money in the long run? Especially if he also sells the driver in the aftermarket as a Klipsch upgrade, further offsetting the development cost. And thank you for the information on the data collection.

    Ultimate Chorus II Upgrade

    Please see my response in the aforementioned Forte II thread for applicable issues

    forte II w/ A-55G Mids?

    Ok, so back to this... the primary issue here is that while the flange at the end of the horn is a mounting flange for the K52 motor assy (diaphragm/magnet) it is NOT the beginning of the horn. The horn actually starts about 1.5-2in up from that flange. This is why the commercial/pro version is shorter. That 1.5-2in is the compression chamber that the phase plug normally resides in. Essentially whats happening here is that at the end of the driver pictured the wave form is being allowed to expand and then is being re-compressed before then travelling through the horn throat normally... it's not a desirable thing and is very likely introducing a fair bit of distortion.

    Again, while probably realistic, "10 years and $150k" is very much ad speak... no one really knows how much he spent exactly? and 10yrs could be 10yrs off and on in his free time? Also, while he seems to be charging a pretty penny for these via aftermarket, the primary benefit of producing his own driver would be production cost savings for his speaker line. You can google "HPS4000" if you want to check out his companies page. As for your reply to my question on the displayed measurements... I think you got confused. While I would like to see tests on other Klipsch horns (the posted graphs used a K401), I was actually asking how many drivers were tested in the collection of the displayed data. Was it the avg of 10 or 20 drivers? or just one of each? I ask because if it was just one driver a piece the touted benefits could be negligible as other drivers from either production company could measure slightly better or worse? I mean we aren't talking about an earth shattering difference in the first place? If multiple drivers were used how do I know that the best A55G isn't being compared to worst K55 they could find? The data appears to come from either Al, Dean or Bob... none of whom I believe would purposely try to deceive anyone on this form but I would still like to see more relevant information. I really mean no offense... I just tend to always approach these types of things with a health dose of skepticism. I mean the K55/PD5V is an excellent driver (also a clone of the Western Electric 555) but that doesn't mean I want to use it on every horn or in every application that requires a roughly 400-5kHz response? I may prefer the voicing of driver X for certain projects or just want something different now and then? Actually, if the A55G was just mentioned as an alternative to the K55 rather than the universal upgrade of a life time I'd likely be less skeptical because nothing is universal and the A55G/K55 is very different from the K52.

    I don't have time to explain right now but this is a terrible idea! Just because you can throw an adapter on it and it makes sound does not mean you should! This actually reminds me of a quote...

    forte II w/ A-55G Mids?

    I actually asked this in another post and never got an answer but how many drivers were tests in collection of this data? Is this a one to one comparison or avg of a batch? Which version of the K55 was used and was it new/nos or did it have several hours on it? Though I am not in the market, if I were I would personally be concerned that the 0.58%THD reduction being touted is just ad speak and may not be any better or worse than the manufacturing tolerance either drivers QC might allow? I have definitely owned enough K52/55's to see what I would consider noticeable variances and the aftermarket can definitely be worse! I would add that you might want to also consider testing the drivers on a K700 and/or K600 so that you can include actual data from a series of K52... if the A55G is going to discussed as an adequate replacement for that driver
  14. I’m going to second Nikko components. I currently have or have owned a Beta 20, Beta 30, Beta 40, EQ 20, CO 23, Alpha III, Alpha 130, Alpha 220 and a couple integrated amps that I can’t remember the model numbers of... all have been fantastic pieces, well designed and generally easy to work on/recap. I am also currently running a Marantz 1070 upstairs with what I will call a modified pair of Heresy’s and enjoy it. It replaces a Sansui AU317 that I also liked quite a bit but needs work currently. Despite both amps pushing relatively low wattage, I’ve never turned either up past 50% and both have had excellent bass response. I would like to, at some point, check out a few power/pre-amps from both brands... though I am thinking my next acquisition will be either a McIntosh MAC4100 or MC250 or both?
  15. Big thanks to jjptkd for helping me out in acquiring the second K603!
