Light bulbs as dummy load for Stereo ?

Was curious if anyone has done this before, instead of using resistors or other test gear as the load in place of actual speakers to protect the speakers?
the actual resistance of a typical light bulb changes as it heats up..in truth some have used them in crude sound compressor circuits a long time ago..

If you are just worried about DC, then I vote for a capacitor in series with the amp output.
Two large (1mF) electrolytic capacitors back-to-back should do the job.
