The biggest thing you will gain is more speaker wire, and be able to adjust the tweeter volume level

and maybe gain a little more headroom. You will not really double the power - you will split the signal
between the woofer and tweeter > when you remove the jumpers from the terminal plate (important to
remove them). One channel will be sending 110 watts to the woofer, and the other 110 watts to the
tweeter, this will not double the power as a whole.
Also, the 225 watts that Definitive says they can handle, may mean short term peaks.
A lot of times based on program material, your receiver is not putting out close to 110 watts at once.
The Bose speakers can only handle so much power at once - their woofers like to burp and they have
a protective circuit in the crossover - I think the 201 is only able to handle around 75 watts long term.
What is the model number of your Yamaha receiver?
