Well, I was in Costco today and came across a Sound Dynamics by "Energy" sub. It is an 8 inch sub, with a 80 watt RMS amp. and a fixed crossover at 120 Hz. I decided to pick it up and try it out for $180 CDN and based on Costco lenient return policy.
So far it is just OK, being an 8 ich it certainly lacks the "boom" I am used to. I still need to play with it some more though.
My question: Does anyone know anything about Sound Dynamics or have any experience with this unit?
