IMO, the best thing to do would be to rebuild the cabinets in some A/D
plywood. Particleboard is very heavy to move after a nights gig,
especially if you don't have a ton of roadies. The plywood would also
be much stronger that the particleboard.

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.

I've heard you mention this truck bed stuff before Scott but I have
no idea what it is. Clearly in the UK it's called something else. The
OP's in the UK too btw.

Do you have a link to a supplier ? Would be interesting to see the
description and try and make sense of it.

You dont build boxes out of plywood or particleboard, for a proper build,
you build them out of MDF, preferably 3/4" or 1"

Obviously, these guys know nothing at all about building loudspeakers:

DJ, since you know so much more about about building SR loudspeakers than
Community does, why not try to share your wisdom with them, and get them all
straightened out?

Thanks, Arny.

They have just the one distributor in the mainland UK - kind of explains
why I never heard of it I guess.

Looks interesting.

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.

Do they have sufboard shops in East London?

You dont build boxes out of plywood or particleboard, for a proper
build, you build them out of MDF, preferably 3/4" or 1"

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?

as for instals I really doubt you can get a" overhead use " sign off
for mfd without extreme internal steel structure
Never hang mfd boxes unless your using factory provided hang points
and hardware

Are you talking A-7 as in Speaker Cabs the old Altec Lansing type? Wow I

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.

I recently acquired 4 18" scoop bins at an absurdly cheap price
due to reclaim of storage space.

Unfortunately, they are made of High Density chipboard,
and covered with aged vinly covering, but have good dimensions and are
VERY,
VERY solid.

My "Sound Guy" I took with me to check them out before buying them, said
it

resin.

I am in E London.

Q1. Where can I get fibreglass spray in London?
Q2. Is it better to paint boxes first, then spray/paint on resin?
Q3. Would it be cheaper for a cabinet maker to do it ?

Thanx in advance.

There are new wonders every day, but I've never heard of fiberglass spray.

Traditionally, "fiberglass" consists of glass fiber, either in the form of
a
woven mat, or a thick muddy mixture of glass and resin.
The resin has two components, much like epoxy. There is a hardener.
The resin contains methyl-ethlyl-ketone, which means it smells very strong
and very bad. I would not do this in a very densely populated city area;
you
can get away with it in the suburbs.
