    • @JAdamsky,   Seams to be a similar-named member on the forum, @jadams2ki, if that is not you, then welcome to the forum.   Could it be that you also have a pair of KLF-20s and a single KLF-C7?   Just asking so no one else gets confused.   Yes that would sure help.   Bill
    • That's why I started about the wire more at first on page 1. Sounded abit odd for this day and age. Used some copper clad steel coaxial cable. It was a compromise and shortcut. Nothing like the real thing, and not have it haunt you meanwhile. Buyer beware...
    • Magnificent, hope you are happy with your effort 
    • It would be similar to taking a power cord with two male ends and plugging them in at the same time.  ⚡
    • Give me a minute(a few hours) to convince, persuade, butter up, manipulate, beg, my bride.   I'll get back with you.  If someone else claims before I return, then all is well.   Bill
    • For a while in the mid-70s, Klipsch had stationery that mimicked this badge. 
    • My first thought is a Speaker switch.
    • No, it's not okay.   If you leave the bridging terminals in place, you'll be feeding voltage from one system back into the outputs of the other system. Bad, possibly damaging to at least one of the systems.   If you remove the bridging terminals and run one system into one pair of terminals, and the other system into the other pair of terminals, what results is, one system only operates the woofers, while the other system only operates the remaining drivers (midrange, tweeters, etc.).
    • Roy has apparently designed an in-throat acoustic lens to spread out the polars above 6-8 kHz and he's stated that it works in that regard only up to ~13-14 kHz.  The Axi2050's 3-part phase plug (which is extensive) is apparently untouched.   I think it's easier in a home environment just to point the loudspeakers at the listening position a little more because at those frequencies, they're not really bouncing off the room's boundaries and arriving at the listener's ears to increase the perception of "image broadening" that Toole refers to.  At those frequencies, you're only getting the direct arrivals, and you're not hearing very much from in-room reflections, anyway.  Pointing the loudspeakers at your listening position is much more effective in that regard.    Now, if you're designing a loudspeaker for commercial cinema duty, that post-phase plug in-throat lens might make a lot more sense, since the audience needs uniform illumination across that frequency band at every seat in the auditorium.  They can't all be at a "sweet spot".  But in a home environment, the listeners (more than one) can easily accommodate being within 15-20 degrees on-axis by positioning the loudspeakers accordingly at the geometric center of the listener positions.   So in other words, that money may be spent better elsewhere--like with a bass bin that has a bit more driver area to reduce modulation distortion due to the higher excursions of the fully horn-loaded single 12" woofer (even with a rear wave rectifier--the internal bass reflex ports), or adding a nose to the bass bin to spread out those lower midrange polars more effectively.   YMMV.   I think that I said that, above.  The Axi2050 cost is lower (in general) than other well-designed 2" throat beryllium diaphragm drivers, and the f3 of the horn/driver is an octave lower than all other 2" compression drivers on a K-402 horn.    If the affinity for "W" section dual mouth folded horn bass bins is still overriding, then using the Axi2050 addresses the one true Achilles heel of the Jubilee (present and future version): its lower midrange crossover interference band jump from the centerline of the K-402 to the centerline of the bass bin, which comes at a point that's in the middle of the vocal range (400-600 Hz) in the present model.  I simply move the K-402 horn closer to the centerline of the bass bin to reduce this issue, and while this is a significant improvement in that area, doesn't actually solve that issue. Crossing over an octave lower is another way to lessen this issue (and the related issue of the truncated horn mouths that do not rejoin).  Elimination of that issue is available by using a full-range MEH approach.   Chris
