raymonda,
It is a difficult question. I have never tried to compare my system to the character of a particular car. I think I will have to compare it to a Hummer. The reason that I make that comparison is not because I have an extremely powerful amplifier. In fact, I have three amplifiers in rotation, and one is an 8 watt 300b, but my speakers are large with (2) 12 inch bass drivers and a large horn in the center and they are dynamic, and capable of playing at very loud volumes.
For that reason, I make the comparison. They are not dainty, and even though they are capable of delicate nuance, they're not afraid of driving in the mud.
