In this review, we will be comparing C 95 II and BW 603, two Passive Floor-standing speakers from Jamo and Bowers Wilkins. Let's have a brief look at the main features
of Jamo C 95 II and B&W 603 first before getting into our more
detailed comparison.
What size room are the Jamo C 95 II and B&W 603 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Jamo C 95 II and B&W 603 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that C 95 II is a 2-way design whereas the BW 603 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Frequency Response
C 95 II has a frequency range of 37-24k Hz whereas BW 603 has a frequency range of 48-28k Hz. With a minimum frequency of 37Hz, the C 95 II can go significantly deeper on the low side and provide stronger bass compared to the BW 603's min frequency of 48Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
C 95 II is a 6 ohms speaker compared to the BW 603 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 95 II sensitivity is rated at 89 dB and the BW 603's is rated at 88.5 dB.

Power Range
Power
range 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.
C 95 II can handle a max power of 200 watts RMS from the amp the whereas C 95 II has a max power handling value of 165 watts RMS , 35 watts less than the BW 603.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Both C 95 II and BW 603 features dual binding post speaker terminals for bi-amping or bi-wiring.
Jamo C 95 II's Posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both C 95 II and BW 603 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
Physical Specs
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 Jamo C 95 II's and B&W 603's external dimensions. Jamo C 95 II has external dimensions of 982.0 x 247.0 x 383.0mm ( 38-5/8 x 9-11/16 x 15-1/16inch) 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 57mm narrower and 43mm less deeper than Jamo C 95 II but it is also 3mm taller.
Below you can see the front view size comparison of Jamo C 95 II 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 Jamo C 95 II is approximately 946.0cm2 / 146.6inch2 and base area of the B&W 603 is approximately 646.0cm2 / 100.1inch2. The C 95 II requires 46% more surface area than the BW 603 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Jamo C 95 II weighs 19.91kg / 43.8lbs and the B&W 603 weighs 24.14kg / 53.1lbs. This makes the BW 603 21% heavier than the C 95 II.
Here is a comparison of how C 95 II and BW 603's weights compare with the average, max and min weights in Passive Floor-standing class.
