Studio 680 features a 1" compression driver with HDI (High Definition Imaging) waveguide Tweeter and 2 x 6.5" PolyPlas Woofer. On the other hand, the Studio 2 55IW features a 1" Hard-Dome Tweeter and 2 x 5.25" PolyPlas Woofer.
Frequency Response
Studio 680 has a frequency range of 38-40k Hz whereas Studio 2 55IW has a frequency range of 40-20kHz. With a minimum frequency of 38Hz, the Studio 680 can go slightly deeper then the Studio 2 55IW's min frequency of 40Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.

Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Studio 680 can handle a max power of 200 watts RMS, whereas Studio 2 55IW has a max power handling value of 120 watts RMS, 80 watts less than the Studio 680.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Studio 680 features Binding post posts which make bi-amping or bi-wiring possible. Studio 2 55IW has a Spring posts which doesn't feature bi-amping/bi-wiring.
