Title: Iím painting my Subwoofers white
Post by: Dave Guilford on May 02, 2021, 02:51:57 pm
Iíve got some old ugly YorkvilleĎs that I got used and I need repaint them for an upcoming installation. I want them wait, what kind of paint do you guys recommend? I know thereís that truck bed liner stuff that everyone loves for black, but thatís no good for this.

If you're installing them and not hauling them around, Rustoleum will work just fine.  Allow to dry a week or so and put on moving blankets to haul.

I think I'd try Duratex white. 
Duratex is good paint.  The black can slightly grey over time, and kinda sticks boxes together when stacked and stored. But short of commercial grade stuff, good epoxy, Line-X etc, it's a good budget type choice (in my limited experience).
All that said, I've never used white.

If they are black now is it best to strip them down to bare wood first?

Or could I just use like 3 layers of primer?

More than the type of paint, surface prep is key!

Do you have an electric or pneumatic powered sander?  A DA or dual-action, that oscillates & rotates with a round pad/disc is probably the best - what I would use.  Depending upon what the surface looks like, #60 grit sanding discs to prep it and remove material.

Depending upon how beat up they are, and how nice you want them to look - get some bondo and plastic squeegees to apply it.  Hand sanding block as well.

I wouldn't strip to bare wood as it's not a furniture refinishing project.  Especially if using a textured coating that is applied with a roller.

Clean, dust free surface that the paint will stick to.  Depending on the finish that is on them now it may require sanding off the existing paint or at least the existing outer layer.  If you donít go down to bare wood then after throughly cleaning and degreasing the surface do a test on one side just to see how adhesion and coverage goes.  You donít want to jump in and paint them all just to later find out you have to sand it back and start over.

Vacuum dust.  Donít blow it off with an air compressor.  You want to remove it from the environment not put it into the air so it falls back down on freshly painted surfaces.

^^^ What Erik said.

I would probably prime them with compatible primer to whatever topcoat you choose when going to a white final color.

Goes without saying, but I'd take everything out of the subs before sanding/painting. No matter how well you mask off stuff, dust will get everywhere...

on the grills look for powder coating companies that do auto parts - will last a lot longer than paint.

What should I expect to pay for powder coat?

It's been too long since I powder coated rims for my 67 Lemans (2009) and will also depend where you are, etc. I'd call around and ask.

Hi Dave,
Last year we installed 4 SRX 712 tops and 2 SRX718 subs. We took them out of our stock, cleaned them with a water based degreaser and painted them white using spray Rustoleum for the grills and metal parts and roll-on for the boxes.
They have held up really well but the tops are flown and the subs only get moved occasionally.
If you need something way more durable then look at 2 part epoxy type paints. (sorry for the low quality photo)
We painted over the factory JBL coating, no need to take that off.

I am in the process of refurbing and painting a bunch of vintage Meyer speakers [UPA1C, USW1, UM1] with the black Duratex. The first speakers I used their foam rollers but I just bought a hopper paint gun to do the rest. I havenít gotten them all prepped yet so canít comment on the air gun. Acrytech was very helpful with any questions and gave me suggestions. It seems pretty durable once cured and looks good. I used their wood filler and just primed those patches. New foam grilles, logos etc. These old speakers still sound very good with the analog processors I found on eBay [yes I am nuts but it is fun].

Are you replacing the grill cloth, too?

Dave, hands down Powder Coat is superior to any roll-on, brush-on, spray-on product.  I considered having the wheels on my jeep powder coated.  Decided to sand blast myself and hammer finish black rustoleum with some satin clear urethane over that and then into the oven a couple of hours.  They look great and are holding up very well over the past 6 months.

If the grills are in a high traffic area such as a dance floor or other high traffic area you may want to consider power coating them.  For anything less in terms of use, powder coating is probably not cost effective and isn't necessary - especially if they are to be flown or in an area where they won't get kicked.

If this is something you expect to do more than once and parts are relatively small - look into buying an old oven from Craigslist and wire up a 240V circuit in the garage.  It's not too bad for cost then, and you'll suddenly notice a whole ton of stuff that can now have a durable finish in (insert your company color here) color!

Lots of good advice here.  I would suggest a trip to your local Sherwin William Paint store.  They people there are usually pretty knowledgeable and will steer you well.

Follow up.

The talk about powder coating led me to ask my Facebook friends who I knew. Through a conversation - turns out I have a friend who works at a place. Heís also a musician and soundman. Knew exactly what I needed.  $200 for pro paint of cabinets, and powder coat the grilles.  Theyíre some 2x18 Yorkvilles fwiw

Given the amount of labor... $200/unit seems pretty reasonable.

1 thing with powder coat.  Too much new material can reduce the ratio of free air to grill and reduce airflow.  Doesn't sound like much but...  there's a whole lotta holes in that perf grill and so the cumulative reduction can be significant ...  something for the powder coated to be aware of if he doesn't do audio regularly...

Iíll consider it a great deal then, because itís $200 for both  ;D

Most busy powder shops have days where they just run black(s). The marginal cost of running your 4 pieces in minimal. That price is outrageous - and I'm in New York.

$100 a cabinet is basically cost, a killer deal for you - for that price, let them do the work, don't touch them yourself.  Have a look at what they do to ensure it's all legit.  You may want to do some touchup first to the cabinets if they're beat up.
