Very bad advise based on information the OP has posted so far and simply because he is experiencing intermittent crackling and pops doesn't automatically equate to amplifier overload or overheating and he hasn't reported any overheating of the amplifier. miketn

Your amplifier could have an intermittent bad connection or intermittent component failure like transistor, resistor, etc... hard to say without more troubleshooting. miketn

Have you tried both the 4ohm and 8ohm taps of your amplifier to see which sounds best in your situation…? Never underestimate the importance of moving the speaker positions even a few inches can make significant differences and it’s free. Pictures of your room/system setup would help us understand your situation better if you care to post them. I do agree with some break in time for new loudspeakers especially for the bass. miketn🙂

The magic of the La Scala AL5 and Tubes sometimes things just come together if your open minded. They appear about 1:45 in the video and you can tell they are still like little kids having fun with this audio stuff after decades in this hobby. miketn

They benefit from a well implemented sub just as a Klipschorn would but “need” is more a situation and taste dependent factor IMHO. Dang and here I’ve been enjoying my Cary CAD2a3 SE mono-blocs on my La Scala AL5…. 🙂 miketn

Just because the La Scala was first utilized for sound reinforcement doesn’t mean it wasn’t for HiFi utilization and as a matter of fact PWK advocated it’s use between his Klipschorns in a 3 speaker array where it was used in the most critical position as a center channel speaker in a HiFi System for the home. miketn

Received my copies..🙂 I’m absolutely blown away by the Quality, Feel and Beauty of the “DOPE FROM HOPE” book…!!! Packaging was 1st class all the way..!!! miketn

I use to wonder the same things especially with my UG Jubs but after I added the KPT-1502-HLS prototype to the system I was amazed at the amount of realism it added to many recordings that you would never expect. For example I love a lot of the older acoustic blues recordings and when the sub was added I was shocked at the increased sense of the acoustical space of the recordings with an increased spaciousness/envelopment with the musicians clearly more defined/realistic within that space. There is also a perception of increased clarity in the rest of the spectrum with an improved overall tonal balance which is especially and easily audible when you turn the sub off and on. After experiencing this sub with my La Scala AL5s and my UG Jubs I really don’t consider it an option but actually an essential part of the systems which brings the systems to another level that IMHO isn’t possible with any electronic improvements someone could add to their system if they already have descent equipment. IMHO Roy’s vented horn loaded subs are the absolute cutting edge designs with shocking clarity that makes someone feel as if you can actually count the frequency cycles being reproduced which I have never experienced with any other sub design types. The clarity/definition is incredible with Roy’s horn/vent sub design. IMHO Subs of these qualities when added to your systems will connect you with the musical performance in such vital ways to realism that until you have experienced it most listeners simply can’t imagine. miketn 🙂

The black HJs are beautiful and I felt the same way Heinz…the irony 😄 Thorens TD124 /ll SME 3009 series ll audio-technica VM 95SH/H

There are (5) Klipsch UG Jubilees total {ie: (3) behind the screen and (2) for rear surround} + the Heritage Jubilee pair for L + R channels in the home theater room. You can see (2) of the UG Jubilee-K402 elevated somewhat above the screen in the picture I posted.

They are like many of us who have been dedicated Klipsch enthusiasts for many decades when it comes to our music…. 🙂

I wanted to share some pictures with those here who enjoy viewing music rooms with great equipment. The pictures were taken during our visit with some dear friends who truly love sharing their music through their Klipsch Collection as well as sharing some of the most enjoyable meals a person could experience. miketn 🙂 This is their Underground Jubilee clones with retro equipment collection that they restore and enjoy in all their systems. Heritage Jubilee in their living room with McIntosh MC30s and a Custom 45 single ended tube amplifiers. Theater Room which can be switched between Home Theater duty as well as 2-channel Music with again his custom built Tube Preamplifier and 300B Amplifiers. Heritage Jubilee and UG Jubilees for surround and center duty with a KPT-1802-HLS sub as well. Pictures just cannot do justice to these Klipschorn AK6 “Teak with Lambs Wool” which serve as a bedroom system again driven with great tube equipment he has restored.

I had taken “pnort” post as a joke about people taking a brand new klipsch design and screwing with it but if it wasn’t then that’s not cool..!!! miketn

Really appreciate everyone taking the time to post their pictures and impressions..!!! Thanks, miketn 👍🙂

Events like this are a wonderful place to meet people and make friends with others passionate about sound reproduction and especially to learn the fundamental reasons behind PWK’s and Roy’s design choices and directions. Have a “GREAT TIME” everyone…!!! miketn 🙂

I have my McIntosh C50 with 8-Band EQ Tone Control setup within easy reach of my listening position and it’s very instinctive to adjust while listening for the most musical and realistic reproduction when recordings benefit from it and easily bypassed with one button push when listening to excellent recordings. miketn

IMHO it’s best to look at these McIntosh Loudness and “Broadband Design” EQ Tone Controls as (best and most appropriately) used for less than ideal recordings and should be adjusted by ear to taste depending on the recordings. I find their use very valuable in widening the amount of recordings that I can enjoy through my system. miketn Here you can see from the McIntosh MA6200 manual the operation range and suggestions for their use.

Manual says 40 over a wide band which is fine in the real world. Here is the manual: ma7200om01.pdf Page from manual showing damping: As KT88 said I believe you might find you love this combination with your Cornwalls.. I also like that Tone Control is available for less than ideal recordings and sometimes helpful in less than ideal room/setup limitations. miketn

Thanks my friend for the kind words..!!! Maybe “NOT crazy” but more of an enabler and it’s important to remember an enabler has the effect of not making someone else feel crazy…. 😄 The “Underground Jubilee” and Heritage Jubilee have such wonderful stories, history, and people that have surrounded and supported them that make them very special in so many ways. miketn

Yes …. Please share your impressions and pictures of the room/setup if possible would be appreciated ..!!! miketn

Thought it would be helpful to post here on the klipsch forum in case anyone here is on the list.

NOTE: I’ve reposted this from an old thread of mine here in case anyone uses one of these units. EV DX38 comparison to EV DC-One to demonstrate that both units parameter set points respond identical to each other. For any DSP Active Crossover users that might be interested in either unit here are some test comparison showing how these units perform very close to each other on the same (KHJ-K402/TAD4002) program settings. The EV DX38 = Red Curve The EV DC-One = Blue Curve Test between my units show the EV DC-One has about 0.7db to 0.9db more sensitivity/gain across the frequency spectrum shown. One other observation is an insignificant slight difference in the 32Hz PEQ filter's actual center frequency with the (EV DC-One = 32.2Hz) and the (EV DX38 = 31.8Hz). miketn Here are the LF Channels comparison: Here are the HF Output Channels comparison. The EV DX38 = Red Curve The EV DC-One = Blue Curve miketn

I thought it might be helpful to simplify for demonstration purposes to just do the simulations of the (EV DX38 LOSLV)/(Xilica XP/XD 4080 Lo-Shelf) filters to demonstrate how well the parameters changes in the Xilica match the EV when implemented. miketn EV DX38: LOSLV (FREQ: 5.4K), (Q/Slope: 12), (Level db: -10) Xilica: Lo-Shelf (FREQ: 4200Hz), (1.80 Oct), (Q=0.751), (Level -10.00dB) NOTE: Both of the LOSLV/Lo-Shelf filters combined in this comparison below. EV DX38: LOSLV (FREQ: 2.5K), (Q/Slope: 12), (Level db: -1) Xilica: Lo-Shelf (FREQ: 2500Hz), (1.80 Oct), (Q=0.751), (Level -1.00dB) EV DX38: LOSLV (FREQ: 5.4K), (Q/Slope: 12), (Level db: -10) Xilica: Lo-Shelf (FREQ: 4200Hz), (1.80 Oct), (Q=0.751), (Level -10.00dB)

Roy’s Underground {Jubilee with K402 & TAD 4002 v1.0 (8/19/2008)} parameter settings from EV DX38 program and the resulting curves in the Race Editor Software for the EV DX38. miketn NOTE: The required Lo-Shelf parameter changes necessary for the Xilica XP/XD-4080 DSP output curve simulation to match Roy’s original EV DX38 output curve simulation. EV DX38: LOSLV (FREQ: 2.5K), (Q/Slope: 12), (Level db: -1) Xilica: Lo-Shelf (FREQ: 2500Hz), (1.80 Oct), (Q=0.751), (Level -1.00dB) EV DX38: LOSLV (FREQ: 5.4K), (Q/Slope: 12), (Level db: -10) Xilica: Lo-Shelf (FREQ: 4200Hz), (1.80 Oct), (Q=0.751), (Level -10.00dB) Note: Tap on the images to enlarge for point to point comparison and even though the scale parameters are displayed differently a careful point to point comparisons will show the exact matching of the output curves from the EV DX38 and Xilica XP/XD 4080 of the two programs with these Lo-Shelf parameter changes in the Xilica XP/XD 4080 from Roy’s original EV DX38 parameters.
