    air flow vs. textured paint?

    i am planning on doing a box with plexi glass inserts, and am wanting to paint the inside of the box with some textured splatter like paint, almost like bed liner but alot thiner. will this affect the airflow much?

    Loudness, a subjective measure, is often confused with objective measures of sound pressure such as decibels or sound intensity.

    You prolly won't notice by ear but the smoother surface would prolly meter a few tenths higher.

    if for looks then do it. If its for spl comps, dont do it. The smoother the better.

    if its only looks and you dont care about spl competing then go ahead. It will not effect the overall performance at all. It will just drop the spl alittle. But chances are you wouldnt notice the difference. Just dont pile it on there.

    Re: air flow vs. textured paint?

    In many applications where volumetric efficiency is key smooth surfaces can be counter productive. There are obviously many variables, but smooth surfaces typically have the most surface tension. Considering the air speeds in a sub application I would expect it to be negligable. Sand-casted surfaces will often out perform a smooth bore . Look up Laminar flow for some interesting reading.

    also think of a golf ball or when nascar started putting dimples in the chambers of cylinder heads to improve airflow.

    Until someone builds an enclosure and tests it out smooth and then paints it with textured paint it's pretty much speculation...

    IMO that word is a reoccuring thing in this hobby.
