What size room are the McIntosh XR100 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the McIntosh XR100 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 XR100 is a 4-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.

XR100 features a 2" titanium tweeter with neodymium-iron-boron alloy magnet dome (x2) Tweeter , a 0.75" Supertweeter , a 2.0" Midrange and 4 x 6.0" Polypropylene Woofer with a Crossover frequency at 300Hz, 2000kHZ and 8000kHZ. On the other hand, the BW 603 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Paper Woofer .
Frequency Response
XR100 has a frequency range of 30-45k Hz whereas BW 603 has a frequency range of 48-28k Hz. With a minimum frequency of 30Hz, the XR100 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.

High Frequency
Floor-standing Speakers
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
XR100 and BW 603 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. XR100 sensitivity is rated at 87 dB and the BW 603's is at 88.5 dB. This 2 dB difference makes the B&W 603 a more sensitive speaker compared to McIntosh XR100, 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. 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.
XR100 can handle a max power of 600 watts RMS from the amp the whereas BW 603 has a max power handling value of 200 watts RMS, 400 watts less than the XR100.
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 XR100 and BW 603 features dual binding post speaker terminals for bi-amping or bi-wiring.
McIntosh XR100's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both XR100 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 McIntosh XR100's and B&W 603's external dimensions. McIntosh XR100 has external dimensions of 1266.0 x 296.0 x 432.0mm ( 49-13/16 x 11-5/8 x 17inch) whereas B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) .
McIntosh XR100 is clearly the larger of the two speakers. Its body is 106mm wider, 281mm taller and 92mm deeper than B&W 603.
Below you can see the front view size comparison of McIntosh XR100 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 McIntosh XR100 is approximately 1278.7cm2 / 198.2inch2 and base area of the B&W 603 is approximately 646.0cm2 / 100.1inch2. The XR100 requires 98% more surface area than the BW 603 which gives it a small disadvantage on placement in tight spaces.
