"Particle bd' or MDF (Off Topic)

Hi Bob,

Mostly what I call PB is used in cheap furniture that always sags and for cheap kitchen counters with some kind of plastic laminate... it swells when it gets wet.

Yep, that is the stuff but then without the plastic laminate. The dense outside and the relative loose inside of these panels absorb energy which is good. The speed of sound in these panels is also different keeping "noise" inside the enclosure and less audible for the "outside" world. These panels have a low Q.

MDF, high undampened Q, is my least favourite material in terms of sound, you can always hear that an enclosure is built from that material giving an artificial sound. Perfect for finishing, cutting and painting though which is probably the reason why most loudspeaker manufacturers use it. It's cheap and less labour intensive giving it's wrongly accepted popularity in the common world.

Ciao,

Bert
