    Excellent price! Did you use this at 96kHz?


    Depending on how you configure things you can have either 48 or 96kHz sampling. The beauty of this Yamaha unit as opposed to others (eg, some Ashley, DBX and Xilica) is that it can accept digital inputs. That way you can avoid the "extra" DAC conversion and its associated "noise". 


    This unit is now sold


    For sale is a Yamaha SP2060 speaker processor. This is a 2 in and 6 out unit.

    The inputs can be balanced or digital (including AES/EBU or S/PDIF). The 6 outputs are Balanced XLR. There are 8 input filters for left and right channels and 6 filters for each output channel (PEQs, Lo/high shelving, all pass filter for correcting phase shifts, etc). It can do the usual time delay, phase adjustments and offers a variety of crossover types and slopes (about 20 different combinations). Of course the input filters can also be used for some DSP room correction if desired (I would suggest using REW freeware to help with this). Setups can be saved and there is the ability to remotely enter and manipulate the settings via a network  (a standard Ethernet cable and downloadable software from Yamaha called "DME Designer").  I have not played with this feature since I simply make the adjustments via the front panel.


    The asking price is $450. If you want it shipped it will probably cost between $25-40 for shipping  within the lower 48. You are also welcome to pick it up in SE Connecticut (about 2hr from NYC or Boston and about 1 hr from Hartford, New Haven, or Providence). These units originally sold for about $2,000. 


    Everything functions and the cosmetics are fine. 


    Here is the manual that will give all the specs. Don't get frightened. It has a ton of capabilities and features but for what we do it is actually fairly straight forward and easy to use.



    Thanks for looking, 














  3. Well, you have not given us any idea what the overall design might be (priorities, budget etc). So comments by me and others might be be wildly off the mark, but that is not our fault since you were the one that did not provide the design goals. 


    That said, I don't believe the K-402 with an adequate driver needs a super tweeter. I say this for several reasons. First, there is not much energy in the highest octave (either from the instruments originally or in the recording). Second, most of us, if we are willing to admit it, don't have very good hearing up at the top of the spectrum. We think we do, but  in reality......... 

    That sad, the original, commercial version of the Jubilee was 3-way system and used a K-510 horn with a K-69 driver as a tweeter and the K-402 was limited to the mid-frequencies. In a commercial application the systems are run fairly loud, 12 hrs/day and 7 days/week so they needed a more robust combination of driver & horns. In a home environment a 2-way is fine.


    Second, although Be drivers can sound wonderful, finding them is very difficult and spares are nearly impossible to find. In either case, those drivers and spare diaphragms can be prohibitively expensive (again you never specified budget considerations). There are others who used Be drivers on the K-402 (JBL 24xx with Truexent diaphragms or simply used TAD 4002 drivers) and reported great success. These were mostly used on the "old" Jubilee systems. 


    My personal advice is that you should first layout your design goals and priorities. 

    Good luck,

  4. Today is Oct 15th, I have discounted the price to $60.

    They sell new on Parts Express for $250


    More recently, 10/27/23

    I may change my mind on this and be willing to ship. My zip is 06365-8617.  I'll let you figure out the cost. Keep in mind that UPS always figures out a way to increase the cost a bit when you actually take it to the UPS store. 

  5. Probably not the crossover, rather a bad connection or failed solder joint.

    Swapping the midrange was a good trouble shooting technique and eliminated something expensive.


    BTW, crossovers are not failure prone (usually), but a bad connection can be. 


    I bet with a voltmeter and a soldering pencil, you could have this fixed in 10 minutes and at no cost.

  6. Edit : November 14th: The subwoofer is now sold

    Edit Oct 15th: It turns out this still available. In order for a quick sale it is now discounted to $60.  Ignore the other prices listed below.


    Is it time to build a subwoofer cabinet? Of course it is !!


    This is a lightly used 15 inch Dayton Audio sub woofer. (driver only, no cabinet). It can be used in a 3 cu ft box for a F3 of about 37Hz (sealed cabinet)  or in a 9 cu ft box for a F3 of 21Hz (vented box). 

    These sell at Parts Express for about $250, I will sell it for $125 (a 50% discount). 



     If you want to get lazy, and we all do sometimes, Parts Express also sells a box made specifically made for this woofer (includes the baffle cutout for the driver).


    It is currently packaged in a cardboard carton that is 18 x 18 x 12 and weighs 36lb. I checked USPS and UPS and the cost is prohibitive, so this is pick up only. 


    As of 10/27/23 .................

    I may change my mind on this and be willing to ship. My zip is 06365-8617.  I'll let you figure out the cost. Keep in mind that UPS always figures out a way to increase the cost a bit when you actually take it to the UPS store. 


    I am located in SE Connecticut (06365). (2 hours from Boston or NYC and 1 hour from Hartford CT, Providence RI, or New Haven CT). They are not currently in a cabinet, but i'm happy to run a test tone through the unit when you pick them up to verify that it works and there are no rattles. 


    Thanks for looking,

    What is really interesting is Digital audio... let's say the recording part, is sampling. I'll use a sampling frequency of 88.2 thousand times a second. That's double a regular audio CD.


    You record the signal level 88.2 thousand times a second, like a picket fence going by. When those get played back at the same rate, just individual levels, you hear all the audio frequencies, tone, percussion, etc.



    It's not magic. The necessary ingredient is the reconstruction filter. Yes, it does work ....

     the H III and H IV sensitivity  are both at  116dB Continuous  , the Heresy 1 is only 96dB continuous on a good day with new crossovers, and drivers , fast forward 40+ years  of wear , it' s  way off .


    what do  these specs  mean , simple , a 3rd  generation Heresy III is  a more advanced Heresy   vs the 1st or second generation ,  and the Heresy IV is even better 






    If the manufacturer is actually stating that the cabinets have 116 dB sensitivity, then do the following three things:  1) read the fine print, 2) take that number with a huge grain of salt, 3) put your wallet back in your pocket (if the "sensitivity" is important to you).

  9. To further confuse the issue.


    Shelving filter parameters can be all over the place depending on the manufacturer. For most the "frequency" of the shelf is the 3 db down point (behringer and yamaha etc). However for some it is the midway point of the transition (I forget if that is "mid" freq on a linear space or log space). I wasted a number of hours "learning about this feature". I think miniDSP may do this, but don't quote me on that.


    Not only that (maybe it was already mentioned), for specifications done on PEQ, although the Q and CF can be similar, the rolloff  with frequency may have a difference in steepness beyond the initial -3dB down point  (ie, different shape).


    As always don't assume assume it might be a simple conversion. If exact values are not needed it may not make much of a difference, in which case ignorance is bliss.

    you are better off buying an original , mint pair of  klipsch speakers    ,   dont waste your time , the wood box will sound like crap .  

    To the OP, not all of us agree with the accuracy of the above statement. Most of us certainly do not agree with the tone and discourtesy of the above statement. 


    I'll be generous and re-frame it. Perhaps there is a note of caution and you will need to do some homework ahead of time if you want the project to be a success. 

    When executed with a plan and and realistic expectations, then DIY projects can be an educational experience and lead to a real source of pride.


    In either case, good luck,

  11. This is not meant to be controversial. It is simple curiosity on my part. 

    In the beginning there were Jubilees sold as a three-way version to the professional community. 


    Later there was a two-way version with a reconfiguration of drivers and DSP settings for the crossover could be obtained. With difficulty, sometimes veneer could be ordered for the front panel. In my mind these are the "Jubilees" (although some call them "underground Jubilees"). They made a splash with home users.  I owned some and they gave me years of pleasure. Apparently Klipsch has ceased production on both the 2-way and 3-way versions. 


    Within the last year the Jubilee was substantially reconfigured, some cosmetics added, and the result is currently called "Heritage Jubilee". My understanding is that this Heritage version is in two forms. a limited production "anniversary edition"  with some extras (special veneer and goodies) and a "regular"  version without the extras and at a slight cost savings. 


    I'm being long-winded since newer members may be unaware of the evolution. (I think I have recalled the history accurately).

    So my questions: How many of the Anniversary versions have been sold? It looks like the regular version regular is in production and about how many of those have been sold?


    I understand there is a reluctance at giving anything other than very rough numbers.

    The reason I ask is IIRC, there is just a single regular participant on the forum who owns the new Heritage Jubilee  (a regular version, NOT anniversary). With other updates, there has always been a beehive of activity from the new owners talking about their updated versions, but I'm not seeing that.


  12. Three comments and a possible conclusion. 


    First, you do not need to spend $80K to get good sound. 

    Second, these are systems employing CD horns (controlled directivity). As such the horn will need some boost and EQing. The DSP settings will be unique to the specific horn/driver combination. Unless this was done, you may have not listened to an optimized version. As far as an analog crossover (network) - don't bother.

    Third, it's unfortunate that Klipsch no longer offers the "original Jubilee" in either the 2-way or the 3-way version.


    Conclusion, since #3 is unfortunately the new reality, I would seriously consider listening to the JBL offerings (M2 is the best, but 4367 is competitive).

    Good luck, -Tom
