OK Guys : it's not about guitar or amps, but Hi-Fi loudspeakers... I recently designed and built a pair of 3-ways Bass-Relfex enclosures : And as you can notice it below, I have drilled a pair of holes destined to attenuators that I won't finally install, so I have to make them disappear... The easiest solution is to plug/seal these holes and cover them with a nameplate of some kind. I designed 3 different models - CIRCULAR, SCHEMATIC and MIXED - see below (you can click to zoom) : - 375L is the code name I gave to the project (for : 3 Ways / 75 Liters). - the plates will be from plexiglas back-painted silver, and laser back-engraved black. If you were me, which one would you prefer ? Up to 3 selectable responses allowed. Any comments or advices are welcome, indeed ! Thanks ! A+!
