Basics and Fundamentals still rules.
Several coats of Automotive grade paint or clear coats on Veneer has No contribution to High Performance Sound.
If anything its Aesthetic Engineering, not Audio Engineering.

There are at least 5 schools of thought when it comes to Loudspeaker Engineering and Designing to produce Sound.
Each with its unique pros and cons.
1) Dynamic voice coil Cone driver (LF, MF) Loudspeakers with Dome, AMT, Bullet or Horn Wave Guide Tweeter (HF)
2) Horn with compression driver for Mid Frequency and High Frequency (Presence) with Dynamic Driver for LF
3) Plannar Design either Ribbon, Magnetic Plannar, AMT (Air Motion Transformer)
4) Electrostatic with Dynamic Low Freqency
5) Omnidirectional Radialstrahler

Dynamic Loudspeaker LF, MF and Horn Wave Guide HF is most common, Powerful, effective and efficient when it comes to Home Cinema whose experience can rival or even surpass Good Commercial Cinema you have to keep these in mind.
Sound SPL of (85dB + 20dB C weighted headroom) per channel / Speaker is what is expected at listening position.
Dynamic Range 85+20 = 105 dB C.

However Loudness has nothing to do with Clarity.
We Need all of this together
Loudness, Clarity, Power, Dynamic Scale, Warmth, Balanced Energy in an Effortless manner.

Several Loudspeakers that sound Musical (dome tweeter / AMT/ Ribbon tweeter) often cannot handle the wide dynamics and power required for an impactful movie experience as they suffer from inefficiency & ability to have sound SPL energy into distance.
So they sound thin, powerless and struggling in Fullness often.

Similarly, if Compression Horn with Bad Design.
Diaphragm diameter to exit throat to Wave guide type doesn't match, can sound h***y, sharp or blaring depending on which element is mismatching resulting in often overpowering the rest of loudspeaker loosing balance in sound and fidelity.
Some Loudspeaker Designs cannot be practically used as Cinema requires direction/ localization, so Omni directional loudspeakers are not suitable for current sound mix and mastering techniques in movies.

Kindly read this letter to understand, not to respond.
Passion is Passion, if it exists it exists.
One doesn't have to prove it.
I Respect that and Understand.
High Performance in Home Cinema & Music is Effortless not just Clarity & Loudness but a combination of Dynamics, Scale, Warmth which is important for an ear fatigue free listening experience.
This is not to criticize any designer or manufacturer.
A natural and intrinsic limitation exists, just have to observe, understand and apply common sense.
Sound follows Physics & Material Science no matter who is the designer, brand anywhere in the world.
Fatigue free experience & listening pleasure. This is crux of High Performance Loudspeaker.
Often size, power, material selection, driver and cabinet engineering plays a crucial role in making a High-Performance Loudspeaker.
often this is overlooked by several High End and Luxury manufacturers
Neither is one's passion bigger than the other just because of spending power.
In the world of High-Performance Home Cinema and Audio Loudspeakers are crucially Important.
This letter is not for everyone.
This letter is for those who seek High Performance Experience despite giving Time, Energy and spending huge money on their passion a void exists.
Let's address it.
Order of High Performance
Loudspeaker
1) Size of the Driver and Type with respect to room dimension where its used and application.
2) Material used for Driver & Cabinet. Transducer motor structure/ power.
3) Configuration of drivers to listening position distance.
