In this review, we will be comparing EVO4.4 and BW 603, two Passive Floor-standing speakers from Wharfedale and Bowers & Wilkins. Let's have a brief look at the main features of Wharfedale EVO4.4 and B&W 603 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how Wharfedale EVO4.4 and B&W 603 compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both EVO4.4 and BW 603 are 3-way speakers. EVO4.4 features a 1.18x2.36" AMT (Ribbon) Tweeter , a 2" Midrange and 2 x 6.5" Kevlar Woofer . On the other hand, BW 603 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Paper Woofer .
EVO4.4 has a frequency range of 44-22k Hz whereas BW 603 has a frequency range of 48-28k Hz. With a minimum frequency of 48Hz, the BW 603 can go slightly deeper then the EVO4.4's min frequency of 44Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers under Floor-standing class in our database.
Impedance and Sensitivity
EVO4.4 and BW 603 has the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.4 sensitivity is rated at 89 dB and BW 603's is at 88.5 dB.
is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
EVO4.4 and BW 603 has the same power range of 30-200 watts.
Keep in mind that higher max power handling value doesn't necesssarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impededance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Both EVO4.4 and BW 603 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
EVO4.4 has a bottom firing port whereas BW 603 has a rear firing ports. Wharfedale EVO4.4's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 603 with its rear-firing port.
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Wharfedale EVO4.4's and B&W 603's external dimensions. Wharfedale EVO4.4 has external dimensions of 1060.0 x 250.0 x 36.0mm ( 41.7 x 9.8 x 1.4inch) whereas B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) .
B&W 603 is 60mm narrower and 75mm shorter than Wharfedale EVO4.4 but it is also 304mm deeper.
Below you can see the front view size comparison of Wharfedale EVO4.4 and B&W 603 in scale.
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 Wharfedale EVO4.4 is approximately 90.0cm2 / 14.0inch2 and base area of the B&W 603 is approximately 646.0cm2 / 100.1inch2. The EVO4.4 requires 86% less surface area than the BW 603 which gives it a small advantage on placement in tight spaces.
