Bronze 2 features a 1" Dome Tweeter and 1 x 6.5" C-CAM Woofer with a Crossover frequency at 3100Hz. On the other hand, the Bronze C150 features a 1" aluminum vented dome with waveguide Tweeter and 1 x 5.25" aluminum Woofer.
Frequency Response
Bronze 2 has a frequency range of 42-30k Hz whereas Bronze C150 has a frequency range of 66-30k Hz. With a minimum frequency of 42Hz, the Bronze 2 can go significantly deeper on the low side and provide stronger bass compared to the Bronze C150's min frequency of 66Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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.
Impedance and Sensitivity
Bronze 2 and Bronze C150 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Bronze 2 sensitivity is rated at 90 dB and the Bronze C150's is at 88 dB. This 2 dB difference makes the Monitor Audio Bronze 2 a more sensitive speaker compared to Monitor Audio Bronze C150, hence will play louder with the same amount of watts.

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.
Bronze C150 can handle a max power of 120 watts RMS, whereas Bronze 2 has a max power handling value of 100 watts RMS, 20 watts less than the Bronze C150.
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.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
