Absolutely. We have discussed all of these issues at great length. I will gradually liquidate a lot of my toys as I get older, as I don't want to leave a huge mess. Plus, I don't want someone else playing their music on my Jubilee's! 🤣 -

It might sound a little 'dry' for most of the bass, and then have what will sound like a +3dB boost at 40. Might work pretty well, would be fine with some sort of active compression. Cabin Gain might make everything I said wrong. -

How will your stereo gear be disposed of once you're pushing up Daises? Does your significant other have any idea what its worth? Have you written instructions? Has anyone given this a thought? Do you have a relative or friend who would value it as much as you do? -
Good job replacing diaphragms. Moving right along...

Thanks Dave. For the amps here, the bottom sections needed refinishing. There's an autobody nearby that will refinish (paint, powder coat) anything made of metal. The paint used here is an acrylic urethane automotive paint (a satin topcoat). After paint is applied, the parts are hung in a benchtop IR oven. Tougher than what a rattle can applied paint provides. The difference between this method and a rattle can approach is the hardness of the paint. Even using a rattle can, an hour or so under the IR improves the durability of the paint. I like the paint shop but I've found another that specializes in small jobs like this and the turnaround is a few days rather than a few weeks. I'll be bringing a set of transformers from a Citation II to them to powder coat in that oddly cool brown color. They match paints using fancy machines and lasers. -
Hi, sorry for the late reply. "Solved" above was the "automatic" reply closing the ticket. There is now a firmware update available via NET, but no information yet about what features or bugs are addressed. https://assets.onkyo-av.com/product-firmware/Firmware_Update_TX-NR7100_TX-RZ50_04_23-2024.pdf?v=1713922940 "Minor bug fixes and stability improvements." Not mentioning the bug in the bass management. From an older posting https://www.audiosciencereview.com/forum/index.php?threads/built-in-dirac-live-not-working-with-upmixing-or-other-modes.49594/ In between, there are actual fixes: As confirmed by Onkyo, the actual firmware contains a bug in the bass management. If there is no subwoofer, the bass redirected to the fronts is not DL corrected. Since the fix so far has not made it into into an official update, I am sharing the link to the bass management fix Onkyo sent me. Use at your own risk. https://drive.google.com/file/d/18HbnGjpK1AS4oWlEeUzIvCDvrey-pmJ7/view?usp=drive_web Please follow the steps below: Preparation: Unzip the file and save all its contents to the root folder of a USB drive. Note: If there are other files on the USB drive, please delete them. Insert the USB drive into the USB port of the TX-NR7100. Procedure: 1. Press the ON/STANDBY button to power on the TX-NR7100. 2. Switch to the USB input and ensure the USB drive is recognized. 3. Press the ON/STANDBY button on the front panel while simultaneously pressing the NET button. 4. The display will show "Update via NET." 5. Use the TUNING UP/DOWN buttons on the front panel to switch to the "Update via USB" display. 6. Press the ENTER button on the front panel to start the update via USB. 7. Please wait without turning off the power until the "Complete" message is displayed. 8. Once "Complete" is shown, the update is finished.
