In this review, we will be comparing XT20 and BRX, two Passive Bookshelf speakers from Polk Audio and GoldenEar. Let's have a brief look at the main features of Polk XT20 and GoldenEar BRX first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how Polk XT20 and GoldenEar BRX compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both XT20 and BRX are 2-way speakers. XT20 features a 1" Soft-Dome Tweeter and 1 x 6.5" Bi-laminate paper Woofer . On the other hand, BRX features a " Folded Ribbon Tweeter and 1 x 6" Polypropylene Woofer .
XT20 has a frequency range of 38-40k Hz whereas BRX has a frequency range of 40-35k Hz. With a minimum frequency of 40Hz, the BRX can go slightly deeper then the XT20's min frequency of 38Hz.
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 Bookshelf class in our database.
Impedance and Sensitivity
XT20 and BRX has the same Impedance of 8 ohms but where they differ is the sensitivity levels. XT20 sensitivity is rated at 87 dB and BRX's is at 90 dB. This 3 dB difference makes GoldenEar BRX a more sensitive speaker compared to Polk XT20, 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.
XT20 can handle a max power of 250 watts RMS from the amp the whereas XT20 has a max power handling value of 200 watts RMS , 50 watts less than the BRX.
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
XT20 features 5-way post type posts and BRX has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.
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 Polk XT20's and GoldenEar BRX's external dimensions. Polk XT20 has external dimensions of 332.0 x 193.0 x 281.0mm ( 13-1/16 x 7-9/16 x 11-1/16inch) whereas GoldenEar BRX has external dimensions of 308.0 x 207.0 x 313.0mm ( 12-1/8 x 8-1/8 x 12-5/16inch) .
Polk XT20 is 14mm narrower and 32mm less deeper than GoldenEar BRX but it is also 24mm taller.
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 Polk XT20 is approximately 542.3cm2 / 84.1inch2 and base area of the GoldenEar BRX is approximately 647.9cm2 / 100.4inch2. The XT20 requires 16% less surface area than the BRX which gives it a small advantage on placement in tight spaces.
