One point to remember:

A new speaker needs to be 'broken in' because the spider and the cone-surround are stiff. Ted recommends using the heater filament winding of a power transformer to drive a fresh speaker at 60 Hz for a while to loosen it up. Or you could play one channel of your stereo into it for a few days. Just be aware that it will not sound right for a while at first.

But when it's ready.... :eek:
