EVO4.3 features a 1.18x2.36" AMT (Ribbon) Tweeter, a 2" Midrange and 2 x 5" Kevlar Woofer. On the other hand, the Prime Tower features a 1" aluminum dome Tweeter, a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz.
Frequency Response
EVO4.3 has a frequency range of 48-22k Hz whereas Prime Tower has a frequency range of 30-25k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the EVO4.3's min frequency of 48Hz.
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.
Impedance and Sensitivity
EVO4.3 and Prime Tower have the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.3 sensitivity is rated at 89 dB and the Prime Tower's is at 87 dB. This 2 dB difference makes the Wharfedale EVO4.3 a more sensitive speaker compared to SVS Prime Tower, hence will play louder with the same amount of watts.
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.
Prime Tower can handle a max power of 250 watts RMS, whereas EVO4.3 has a max power handling value of 150 watts RMS, 100 watts less than the Prime Tower.
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
EVO4.3 features Binding post posts which make bi-amping or bi-wiring possible. Prime Tower has a 5-Way post which doesn't feature bi-amping/bi-wiring.
