Basically I plan to coat my wood cabinet DIY speaker to make it looks more expensive. So far I'm looking to do it similar to Yamaha piano black speaker. However it is quite thick and hard coating.
Question will it affect the sound quality?
I understand it will affect cabinet resonance but for the better or worse? Will it reducing low frequency extension?
By the way if we buy speakers from manufacturer sometime they have different color or coating such as piano black and wood veneer with same drivers, does the SQ different? Which one is better?
Maybe it is just subtle difference and doesn't really matter but I just want to know which one better SQ with or without coating.
cms, aka driver diaphragm suspension mechanical compliance: 0.000065 meter/Newton or in standard form 6.5e-05 m/N. (smaller number is better)
rms, aka driver diaphragm suspension mechanical resistance: 6.41 Newton.sec/meter. (higher number is better)
