Finally the weather returned to reasonable temperatures and I'm able to get going again. Tries Ron's 80 grit on a piece of plywood method of flattening the top facet. Worked great except for nicking a corner and rounding it over. Would have been ally of sanding to fix, so I set up the vacuum rig. Veneer wrapped perfectly along the rounded edge until... Power outage. No power, no vacuum. My band clamps are 2 hours away. So I came up with this, hoping the bag and breather would provide some flexibility to get that round over wrapped.
Also used as much of Ron's veneer patching advise as possible. Epoxy bubbles aren't going to get wet. I used a heating pad with my caul on top to warm the veneer. It was much more flexible and the bubble seemed to want to be flat. Clamping by lead weights.
About half an hour after going out the power returned. Back under vacuum with clamps as a backup.

by technodanvanSuspension
The suspension refers to the mechanical system that provides support and control for the diaphragm (cone/dome) and voice coil within the driver's magnetic structure. The suspension is an important component that allows the diaphragm to move back and forth in response to the electrical audio signal while maintaining stability and linearity. The suspension system typically consists of two key components: the spider and the surround.- Spider: The spider, also known as the "speaker

by technodanvanSurround
In the context of loudspeaker drivers, the surround, also known as the "speaker surround" or "suspension surround," is a component that plays an important role in the driver's suspension system. The surround is typically a flexible ring or membrane that connects the outer edge of the loudspeaker diaphragm (cone/dome) to the driver's frame (basket). The primary function of the surround is to provide a compliant and flexible suspension for the diaphragm, allowing...-

by technodanvanSpider
In the context of loudspeaker drivers, the spider refers to a component that plays an important role in the suspension system of the driver. The spider is an essential part of the driver's overall mechanical structure, helping to center and control the movement of the voice coil and diaphragm within the magnetic gap. The spider is typically located between the voice coil and the frame (basket) of the loudspeaker driver. It is made of a flexible material, such as cloth or treated...-

by technodanvanSoundstage
Soundstage refers to the perceived spatial placement and localization of sound sources in a recording. It describes the three-dimensional presentation of audio, making it seem as if the sound is originating from specific locations within the listening environment, rather than coming directly from the loudspeakers. When a recording and playback system is capable of creating a convincing soundstage, listeners can experience a more immersive and realistic audio experience. The...-

by technodanvanSINAD (Signal to Noise and Distortion ratio)
While not directly applicable to loudspeaker design, SINAD is a term in common use and is a valuable tool when comparing electronic equipment to match with your speakers. It can also be used when deciding what equipment you'd like to use for your measurement setup. SINAD stands for "Signal-to-Noise and Distortion ratio." It is a metric used to quantify the audio quality of electronic devices, particularly audio equipment like amplifiers...-

by technodanvanSignal-to-Noise Ratio (SNR)
The signal-to-noise ratio (SNR) is an important parameter that helps evaluate the performance and quality of the audio output. In the context of audio, SNR refers specifically to the ratio of the desired audio signal (the sound produced by the loudspeaker driver) to the background noise generated by the speaker itself or the overall system.
The formula to calculate SNR in decibels is:...
SNR (dB) = 10⋅log10(PowerSignal/PowerNoise)-
