Hmmm lets think here. Who has built the best speakers over the years as
close to what you are trying to accomplish hmm?
Now, what did they use for an encloser...lets see Bose 301,
901...Infinity...Klipsch...My Altec Lansing Voice of Theater?
Now what are they made of.....they are the Best right.....they still sell
way above anything else on the market 25 years old right?
Sure they do ...just take a look see....you know it now and so it's
obvious,
unless well you don't know **** about speakers or enclosures.....see that
wasn't hard was it?
MDF, HDF, MFD, WTF?
So now that thats settled...let move on shall we.....ok I have 8 monkeys
to
screw this one board together and...........Oh sorry anyway

So we know we pack speakers correctly using padding right.........what
kind
folks?...I can't hear you? Hmm kickass ones use sand........**** did he
just
say sand? OMG, well we can just use nice foam or insulation...say it with
me
I.N.S.U.L.A.T.I.O.N. now lets slap in some crossovers 2Way, 3Way..pop in
our
pole sockets........

Crap I'm waisting my time just use Plexiglass some acetate and lights and
you're all done.

Bose defintly does not make the best speakers thats for sure. If we're
talking PA here, you need to be looking at Turbosound, EV, EAW, Meyer sound,
not bose.

what exactly is your point
Mdf particle board what ever you want to call it is useless for a pro
speaker
it is way to fragile
sure you can make speakers really cheap and sell them for lots of money
to home hi-fi rubes if you use mdf
but a mdf speaker would not last the truck ride to its first gig in a
pro application
and you definatly can not fly a mdf box so that means at best it is a
piece of DJ **** oh wait you are a DJ so this is why you think this way
sorry
wonder why Meyer /turbosound/eaw don't all take your lead and build mdf
boxes?
ever see a mdf box that fell 12 feet to a concrete deck? we call that
trash
and beacuse it is ****ty material it sucks

For home systems, the 1" MDF or HDF is best, but it is way to heavy to
move all the time. For a permenant install, the MDF would be fine. For
portability and strength, plywood is the only way to go.

As to particleboard, what do you think MDF is?

Sawdust and glue.


For a really lightweight cab with cost not an issue, has anyone used Aerolam for
an enclosure ?

I made some enquiries about the fibre glass spraying and it seems to be
costly.

Someone on a net forum just suggested painting with hammerite. Would
that
waterproof and strengthen, or just waterproof..?

Are the boxes weak? trying to spray something on them to strengthen isnt
going to help in the long run.

The Boxes have obviously lasted quite a few years and are still very solid.
They won't be used outside, but may get exposed to rain/weather whilst being
transported to/from events (wedding receptions/hired halls/dinner&dance).

So was thinking of waterproofing and either covering with carpet or
hammerite to preserve them whilst they return to me a tidy income.

My "Sound Guy" I took with me to check them out before buying them, said
it
would be worthwhile to strip the vinyl, and spray them with fibreglass
resin.

Its a little more than just a spray AFAIK, i used to work for a car audio
shop making enclosers, kick pods, panels, bezels, etc.. out of fiberglass
and there was alot of preparation and mixing involved and if not done right
it can be a mess, its also very hazzardess your health and is deadly if the
right precautions arent taken.

Now, dont get discouraged, if you feel you can do it, then i would get
intouch with a fiberglass supply company, i dont know of any in the UK and
the one where i got my stuff from says they wont ship out of the US.

Take it to a surfboard shop and have them do the work. They do it all day
long, and they don't charge a lot.

My question, though, is whether anyone has tried the spray-on truck bed
liner material. Around here, lots of pickup trucks are driving around with
this spray-on polymer stuff in the bed, and there are places all over the
place that are applying it. It looks like just the thing to stiffen an A-7.
--scott

He's in East London Scott, so I doubt the place is brimming with
surfboard shops...good suggestion about the truck bed liner, but again
how many pickup trucks are running around the UK.

Also I wonder about with environmental regs over there how easy it is
to apply fiberglass resin or spray polymers.

IIRC, Fender now paints all their guitars down in Mexico because of
environmental regs in Cali...which is so American - "hey let's go
pollute someone else's country".

Make sure you have some kind of dolly to move them and some help. You
don't want to drop the cabinets because they will crumble where they hit
the floor. As for waterproofing, a good marine paint should work just
as well as all these other options and be much cheaper. Make sure to
make a cover for the drivers that is weather resistant for moving.

How about calling it the way large corporations work and not just
American. I don't agree with polluting of the planet by any country, no
matter how big their pockerbook is and I am an American.

I am sure the labor costs are another factor of this.

Have been told today about a Product from a company in Uxbridge UK, called
"Trimite". Appararently a Primer/Single Coat application used precisely for
PA/Band enclosures.....

Anyone know of/used this before ?

Voice of Theater most awesome cabs ever made.

Yes, but they are have all kinds of wacky resonances. You tap on the cabinet
with your hand and you can hear all sorts of stuff going on. That's why they
need to be stiffened. Problem is that most of the reinforcement also involves
adding substantial weight to the boxes. That's why the spray-on stuff looks
like it might be interesting (although still some additional supporting members
in the box would be a good idea).

I've built hundreds of subwoofers, most of the twin 18" peavey lowrider
subwoofer boxes, and have not once trusted the boxes to MDF. MDF is used
for low sensitivity car audio subwoofers, and should stay there, its far too
fragile and has no shock resistance
