I just received a 10" mb quart PWE subwoofer, it was one of those subs that crutchfield was clearing out a few months back.
upon inspection of this sub I noticed that the suspension is super duper stiff with a super stiff spring like suspension.
Not only is it super stiff, it seems to be "pressurized" outward away from the magnet.
I don't see how this sub can get goiing with anything less than a real 600 watts rms of amplifier power.
what are the characteristics of subs like this ? why would a manufacturer-designer decide to make a subwoofer with such a stiff suspension ? what are the pro's ? the con's ?
