seti Posted April 6, 2007 Share Posted April 6, 2007 If I remember the discussions about the Jubilee another strength was that it was abit more efficient than any previous heritage design. How efficient is the Jubilee? I seem to have numbers from 107db-110db @ 1w 1m running through my head. This would be the k69/k402 combo. Clarification much appreciated. The more efficient the speaker the lower the wattage requirements so what kind of flea amps might we see powering the Jubilee in the future an 1/8th of a watt? *kidding guys* I would actually like to hear MikeTN's PP 2A3 as this was also a favortite tube of PWK back in the day. I do like the SET sound especially the 300B but I would now like to hear a PP 300B. If I liked 300B in SET configuration I would imagine PP would be a real treat for this tube. Has anyone hear had experience with PP 300B amps? If so what amps? I have been looking at the Canary Audio MKII 300B PP. Quote Link to comment Share on other sites More sharing options...
Deang Posted April 6, 2007 Share Posted April 6, 2007 106/107dB with active filters, and a solid 104 with the passives. Quote Link to comment Share on other sites More sharing options...
sfogg Posted April 6, 2007 Share Posted April 6, 2007 When considering power requirements keep in mind the EQ boost for the K402 and K510 horns. That raises the power requirements. With the driver I am using (not a Klipsch unit) in theory you need 10x the power to account for the boost. Having said that I'm running the top end driver with amps that put out 9w (cleanly) and I have no problems. Shawn Quote Link to comment Share on other sites More sharing options...
rigma Posted April 6, 2007 Share Posted April 6, 2007 I will be running 300B's to power the Jubilee hopefully this weekend if I can get the passives done. That is what I used on my Khorns so it should be fine. rigma Quote Link to comment Share on other sites More sharing options...

Dean, Interesting I was way off on that one it seems to be about the same as the Heritage line with passives. Rigma, What brand 300B amps and tubes are you running?

DrWho Posted April 6, 2007 Share Posted April 6, 2007 106/107dB with active filters, and a solid 104 with the passives. What frequency is that measured at? Like is the K402 horn 106dB at with 2.83V at 15kHz? Or is it more like 106dB with 20V at 15kHz and 106dB with 2.83V at 1kHz? Quote Link to comment Share on other sites More sharing options...
