In this review, we will be comparing BW 603 and RP-8000F, two Passive Floor-standing speakers from Bowers & Wilkins and Klipsch. Let's have a brief look at the main features of B&W 603 and Klipsch RP-8000F first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how B&W 603 and Klipsch RP-8000F compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

One of the fundamental differences between these two speakers is that BW 603 is a 3-way design whereas RP-8000F is a 2-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. BW 603 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Paper Woofer . On the other hand, RP-8000F features a 1" Tractrix Horn Tweeter and 2 x 8" Cerametallic Woofer .
BW 603 has a frequency range of 48-28k Hz whereas RP-8000F has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-8000F 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 under Floor-standing class in our database.
Impedance and Sensitivity
BW 603 and RP-8000F has the same Impedance of 8 ohms but where they differ is the sensitivity levels. BW 603 sensitivity is rated at 88.5 dB and RP-8000F's is at 98 dB. This 9 dB difference makes Klipsch RP-8000F a more sensitive speaker compared to B&W 603, hence will play louder with the same amount of watts.
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.
BW 603 can handle a max power of 200 watts RMS from the amp the whereas RP-8000F has a max power handling value of 150 watts RMS, 50 watts less than the BW 603.
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 BW 603 and RP-8000F features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both BW 603 and RP-8000F have rear firing ports. Rear ported speakers generlly need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing too close to the walls may cause the bass to sound boomy.
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 B&W 603's and Klipsch RP-8000F's external dimensions. B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) whereas Klipsch RP-8000F has external dimensions of 1099.0 x 277.0 x 445.0mm ( 43-1/4 x 10-7/8 x 17-1/2inch) .
Klipsch RP-8000F is clearly the larger of the two speakers. Its body is 87mm wider, 114mm taller and 105mm deeper than B&W 603.
Below you can see the front view size comparison of B&W 603 and Klipsch RP-8000F 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 B&W 603 is approximately 646.0cm2 / 100.1inch2 and base area of the Klipsch RP-8000F is approximately 1232.7cm2 / 191.1inch2. The BW 603 requires 48% less surface area than the RP-8000F which gives it a small advantage on placement in tight spaces.
