yung box po ba ng b3, evo or rcf is made of what material (ie mdf, plyboard ) lumubog kasi lahat ng jbl n speakers ko and nalusaw yung mga box although gumagana pa yung mga speakers but i think they may need to be reconed/rewired.... im also still thinking if it is still advisable/practical to go branded or just china made...... medyo nakaka traumatize kasi yung baha recently
you may have speakers with MDF, HDF or particle board which, when exposed to water, absorbs all the water it can take and expands and eventually looses its integrity.
B3 enclosures are made of a couple of materials depending on model.
PLASTIC ENCLOSURESTS and U- Series enclosures are made of high impact ABS. These have also been made to a specific mix so that it would not be brittle as to break on impact. The ABS used is also produced to a have a certain dampness so as not to rattle when playing at high levels.
It has also been UV tested as not to discolor after long exposure to sunlight such as installs outdoors.
a good example are those permanently installed around the Araneta Coliseum, those things have been there for over 3 years, working day in & day out, getting rain, sunshine and the Manila pollution...and still are OK
WOOD ENCLOSURESwooden enclosures such as the Sigma Series use 13-layer Birch Plywood additionally protected by tough paint.
RCF ItalyRCF, being the high quality Italian product that it is, uses Baltic Birch for its wooden enclosure and high grade Composite Polypropylene for its ART Series...
