A2s Surround Sound features a " Tweeter and x " Woofer. On the other hand, the EVO5.2 features a 1.375" SilentWeave cotton and felt damping fiber AMT (Ribbon) Tweeter, a 2" Midrange and 1 x 6.5" woven Kevlar Woofer with a Crossover frequency at 800 Hz and 4.3 kHz.
Frequency Response
A2s Surround Sound has a frequency range of 59-30k Hz whereas EVO5.2 has a frequency range of 44-24k Hz. With a minimum frequency of 44Hz, the EVO5.2 can go significantly deeper on the low side and provide stronger bass compared to the A2s Surround Sound's min frequency of 59Hz.
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
A2s Surround Sound is a 6 ohms speaker compared to the EVO5.2 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the EVO5.2 can provide this impedance level.
These two speakers also have different sensitivity levels. A2s Surround Sound sensitivity is rated at 86.8 dB and the EVO5.2's is rated at 88 dB. This 1 dB difference makes the Wharfedale EVO5.2 a more sensitive speaker compared to Perlisten A2s Surround Sound, 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.
EVO5.2 can handle a max power of 120 watts RMS, whereas A2s Surround Sound has a max power handling value of watts RMS, 120 watts less than the EVO5.2.
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.
