6 6.5 subs, what do you think?

1. eD's business is up something like 7X's this year??

2. Too many people think that particleboard is hunks of wood haphazardly glued together. Not true. Particleboard is an engineered product with specific properties that must be met to have it graded in a specific grade and usage grouping. Particleboard today is not like the stuff we used for cabinets and so on in the 1950s. In many uses' date=' especially structural, and in fastening, particleboard will greatly outperform MDF.

Incidentally, what is MDF? It is the same wood used for particleboard, except it is made smaller (fibers or groups of fibers) before it is glued back together. It uses the same adhesive, too! The June 2002 issue of FDM magazine had a nice summary of the composite board definitions. Read it before making statements that are not really true but that need qualifications.

1.) Ben uses mommy and daddy's money when he gets into a pinch. He remarkets and relables shit constantly and inflates all of his specs...and that is today. Im not even going to go into the past because the stories SHOULD be known.

2.) ok this is from MY experence. MDF holds a screw MUCH better than P-Board. MDF is MUCH easier to cut. MDF makes a better bond with wood glue (greater than the strength of the wood itself). MDF has greater sructural integrity. MDF is more dense which means more acoustical dampening. MDF soaks water, it doesnt disolve. MDF makes a more dead sounding (with the knock test) enclosure when comparing two identical enclosures.

I dont have to post links, that is my experence. The only other fact that I can throw at you is to look at what high end speaker companies and extreme audiphiles use. If they dont use Baltic Burch they use MDF. Some use MDF and Baltic Buch Layred.

Your idea of MDF and P-Board essentially being the same thing is like me saying fiberglass with chop mat and fiberglass with cloth are the same thing. or that cheap pine plywood and expensive marine grade ply are the same.

 
MDF is heavy enoughI cant imagine HDF

Plus its expensive and ugly

oak ply> all !
Marine quality 13 ply Baltic birch/hdf/butyl infiltrated sand and/or lead shot/mdf sandwich for the win!... Seriously there was a nice little waterfall plot experiment comparing all sorts of different materials for high end home audio... This is the closest thing to proof I can find: http://www.aes.org/e-lib/browse.cfm?elib=7384 -- It pretty much says that for low freq. mdf vs pb is a tie... Rigidity increases with the cube of the material thickness and the young's modulus of both materials is comparable.

As for some crazy composites that end up being more than $500/cuft that I'm playing with.... //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif
