Before considering doing the "voice of god" speaker make sure the Auro 3D upmixer in the Denon receiver actually uses it. With my Denon AVR-X4400H, it did not. It was only ever active with native Auro 3D content that had VOG content. For me that was on one disc, a European Blu-ray copy of Pixels that I bought on eBay just to test an Auro 3D movie. I ended up disconnecting that speaker so that I could use the output for another subwoofer.

Four-channel? If you are considering waiting for the new La Scala version, you'll need a 6-channel amp (or two 3-channel or three 2-channel or six monoblocks... 😁). I've already purchased two additional stereo amps in anticipation of the upgrade kit. Got a good deal on two more demo units of the stereo amp I'm currently using with my AL5s.

Be aware, the level controls on the DSP are NOT tone controls, they are gain controls. They are meant to be used when you are using different amplifiers with different gains for HF and LH, for example using tubes for HF and solid state for LF. If the amps for HF and LF are identical, the controls should be at the same position on both. I asked Klipsch Chief Engineer Roy Delgado (@Chief bonehead here on the Forum) about this. He said since I'm using identical amps to just set both gain controls to the 12 o'clock position.

Congrats on the purchase and welcome to the Forum and the Heritage Jubilee owners club. Read through my post here for my experiences after having them in my home for three months, which is the point where I finally got them dialed in where I wanted. The biggest consideration for amplifies is the noise floor. If the amps are not very quiet, you will hear the amp noise. I imagine the Mcintosh amps will be fine. You will most likely not need a subwoofer. The Jubilee is designed to have response down to 18 Hz (-1.75 dB) in half-space, meaning on the ground away from any room boundaries. In all real listening rooms, these will be close enough to the walls or corners for some room gain, making them go even deeper. I had to do a deep bass cut in my room and even with that the -3 dB point is 16 Hz. They can put out gargantuan amounts of deep bass. I suggest you listen and decide if you need more. I didn't.

Winner, winner. Chicken dinner. That's what they were.

@Khornukopia - Thanks for linking my thread. @Philip McDonald - Read through my thread before starting to disassemble the Belles. If you have any questions during disassembly, send me a message.

Very unlikely. Any upgrade kit for these coming La Scala and Khorn changes will likely be limited to AL5/AK6 owners, because the horn for current Celestion tweeter (which is being carried over from the AL5/AK6) would require cabinet changes to accommodate it. I don't know if Klipsch would sell the kit plus the current tweeter assembly to those with older models who are willing to do the cabinet changes themselves.

I asked Roy about this when the Jubilee came out, but I forget the answer except that I do remember that it exceeded the 24/96 of the Xilica.

These prototypes are using standard AL5 cabinets. That bottom hole is just for the wire from the bass bin to come through to go to the crossover, which is in the top cabinet on the AL5. The terminal cup on top of the bass bin is right below that hole. The round hole in the back is there because with the old, really long K-401 horn, the midrange driver does not fit within the top hat. The driver sticks into that hole. I imagine that the rear hole will be eliminated in the new version.

The volume adjustment is done with the volume control of the preamp/processor as usual. The preamp out then goes to the DSP, which divides the frequency spectrum in three outputs per channel. These outputs then go to the different amp channels. The DSP will have gain controls to allow adjustment if amplifiers with different gains are used, for example, if you were to use a tube amp for HF and solid-state amps for MF and LF. If you are using all identical amps all around, then the gain controls all get set the same. This is how the current Heritage Jubilee operates, except you only need two amp channels per speaker. https://support.klipsch.com/hc/en-us/articles/7875531269908-Jubilee-Active-Crossover-Controls-Inputs-and-Outputs

Yes, for the active DSP crossover configuration, you will need six channels of amplification. This can be in either multiple chassis (like three stereo amp) or a single chassis (like a six-channel amp as @jjptkd suggested). I can't speculate whether the DSP will add a "significant" amount to the price or not. We'll have to wait and see. I'm sure whatever it is will be worth it for the very significant improvement in the sound quality. The improvement is not subtle. I assume any upgrade kit would include at minimum the DSP, the K-406 horn, the KT-1133 driver and external phase plug, and perhaps a new input panel with three sets of binding posts. I think the DSP would be required as I can't imagine the new mid horn/driver would work with the existing AL5/AK6 crossover networks.

Perhaps @Chief bonehead can comment on your questions.

Nothing has changed with the design of La Scala bass bin or the LF driver. It's how Roy is using that response with the DSP that makes the difference. He's doing something he couldn't do in a reasonably sized passive network. The native response of the La Scala bass bin has a big hump in it. Because of this, when that response is matched to the mids/highs, the -3 dB point for the bass point ends up in the low 50s. By using the DSP to flatten out that hump (i.e. cutting it down) and then matching the mids/highs to that flatter bass curve, the -3 dB point for the bass ends up in the mid 40s. I've heard the AL5 in that Hope lab listening room before. The low end of the bass wasn't great. This updated La Scala had really satisfying bass in that room. Many fewer people will hear this new La Scala and immediately think that they need a sub to go with it.

Pricing and release dates were not discussed.

Hi All. I decided to start new discussion threads since this one was really an event registration information thread, one for pictures from PWK Birthday Bash in general and one for the Chief Bonehead Class discussing the coming changes to the La Scala and Khorn.
