I'm now seriously considering going ported for my sonosub. I'd have a flared port (FP4) in the top endcap. The top endcap and the flare would be painted white. I want to cover the opening with a perforated metal speaker grill like so many folks here have done, but I can't find a white speaker grill (other than fabric) at any of the usual places (parts express / adire / madisound). Does anyone have a source, or am I just going to have to paint a black grill? Thanks!!
