The first replacement speaker for my gk 200mb sounds for poop. Better specs do not seem to mean a better sounding speaker. (in this box) What to do? A new speaker from gk just went up to about $150.(with tax and shipping). Seems like way too much for such a crappy speaker. The frequency response is 80-2k, 100 watt power and not very efficient at all. There has to be something better or cheaper. HELP!! Also.. It has to be 5in. deep. HELP HELP!!
