Thanks for all the comments.

So, here is another question

VRx lower power but higher end

VS.

LRX higher power but not the highest end in the lineup

Same Money.

Which one would you choose?

 

Is it a power question or a SQ question
... can you hear a difference? probably not
... is one noticibly louder? probably not (assuming same ratings)
... can you afford both
... does image/ appearance matter

 

SQ question but enough power is required to drive the speakers well

Yes, I can afford both.

 

Just cause you got an amp that is able to put out 300W doesn't mean you're feeding that much power to the speaker...

 

^Yes I know. But the dynamic potential is what the power is all about..

 

depends, were just fitting a car with all macrom for a show in winnipeg, we want to get it in the 1-600 watts basic class.. I think were only giving the subs 120 a piece right now< might change. from what I've heard for the sq portion you don't need alot of power for the subs.

more is great just depends on what you need

 

It is a yin/yang thing if you go low power you need efficient drivers to hit 'minimum' SPL levels. I have heard many home systems with satisfying SPL levels with only 13 watts or so (but not playing sub bass heavy music). BUT to get realistic bass slam you need some headroom and some watts (120 W should be enough in a quiet car).

 

Just cause you got an amp that is able to put out 300W doesn't mean you're feeding that much power to the speaker... </font>[/QUOTE]This brings up another point -- many "higher end" car and home amplifiers are "biased" in such a way that in many class "a/b" amplifers (for example Parasound or Quad) the first 10% of the amplifiers capability is biased towards class a -- So, in many cases, not over driving the amplifer allows it to operate more towards the class "a" scale of its bias.

 

I agree Mike, it's not just a question of power quantity, but quality of power.
Power as in Watts, is like Horsepower to an engine, and Amperes are like torque, but all the horsepower without the right amount of torque won't go far.
If it's SQ you are after, and you CAN afford a better amplifier and interconnects, then get as much power as you can afford, and the best SQ amp you can buy, the Audison is a very nice sounding amplifier, so no matter which model you opt for, it's a good choice with many head units and speakers.
