What model Focals?

T.

 

The BT Pros can take a lot more power than the ~150W there getting now. The Pros are rated at 170 watts RMS. If you use the calculation of RMS Watts x 1.8 to determine optimal power you will see that they can take 300W per channel to really shine. 170W x 1.8 = 306 watts. So you can see the Pros are actually being under driven.

 

Donna at BT told me the bt4180 is under rated also. Anyone ever measure these amps?

 

Yes, AAWAV bench tested the 2180 & the 4180 and found them to be under rated at 150 watts at 4ohms. The results can be found up in the bench test sticky.

 

Well there ya go. Thanks

 

When you guys mention more power makes a speaker sound better, do you mean at upper volume levels or is a more powerful amp linear? Will half volume be pushing more juice at half volume compared to a less powerful amp at said same half volume?

 

Where does the factor of 1.8 come from ?

 

From what I'm told, the KRCs.
Have you tested both T?

 

I think they are comparable speakers. They each sound different but as far as quality goes they are both top tier speakers. Just search Focal KRC vs HAT Legatia, both very popular in the car audio world.

 

I do not have the pros....we were just talking about them..
