NS-333 features a 1" Aluminum Dome With Waveguide Horn Aluminum Dome With Waveguide Horn Tweeter and 1 x 5" PMD Cone Woofer. On the other hand, the NS-C444 features a 1" Aluminum Dome with Waveguide Horn Aluminum Dome with Waveguide Horn Tweeter and 2 x 5" Polymer-injected Mica Diaphragm Cone Woofer.
Frequency Response
NS-333 has a frequency range of 65-35k Hz whereas NS-C444 has a frequency range of 55-35k Hz. With a minimum frequency of 55Hz, the NS-C444 can go significantly deeper on the low side and provide stronger bass compared to the NS-333's min frequency of 65Hz.
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
NS-333 and NS-C444 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. NS-333 sensitivity is rated at 87 dB and the NS-C444's is at 89 dB. This 2 dB difference makes the Yamaha NS-C444 a more sensitive speaker compared to Yamaha NS-333, 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.
NS-C444 can handle a max power of 250 watts RMS, whereas NS-333 has a max power handling value of 150 watts RMS, 100 watts less than the NS-C444.
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.
Input Type and Bi-Amping / Bi-Wiring
NS-333 features Binding post type posts and NS-C444 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Yamaha NS-333's and Yamaha NS-C444's external dimensions. Yamaha NS-333 has external dimensions of 320.7 x 200.0 x 212.7mm (12.625 x 7.875 x 8.375inch) whereas Yamaha NS-C444 has external dimensions of 190.5 x 514.4 x 212.7mm (7.5 x 20.25 x 8.375inch).
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Yamaha NS-333 is approximately 425.4cm2 / 65.9inch2 and base area of the Yamaha NS-C444 is approximately 1094.1cm2 / 169.6inch2. The NS-333 requires 61% less surface area than the NS-C444 which gives it a small advantage on placement in tight spaces.
