What are good bang for your buck speakers these days?

When you get down to comparing brands watch out for huge peak amp numbers. Pay attention to the rms(root means square) amp number because that is real working/sounding number.

Butyl rubber surround probably flexes best and lasts a long time.

Waterproof cone material is best

Neodimium (rare earth) magnets are the strongest.

Sony does a good job in meeting the above requirements through ebay for a reasonable cost.
