In this review, we will be comparing BRX and 706 S2, two Passive Bookshelf speakers from GoldenEar and Bowers Wilkins. Let's have a brief look at the main features
of GoldenEar BRX and B&W 706 S2 first before getting into our more
detailed comparison.
What size room are the GoldenEar BRX and B&W 706 S2 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 GoldenEar BRX and B&W 706 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

BRX features a " Folded Ribbon Tweeter and 1 x 6" Polypropylene Woofer . On the other hand, the 706 S2 features a 1" Decoupled Soft-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
BRX has a frequency range of 40-35k Hz whereas 706 S2 has a frequency range of 50-28k Hz. With a minimum frequency of 40Hz, the BRX can go significantly deeper on the low side and provide stronger bass compared to the 706 S2's min frequency of 50Hz.
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 Bookshelf 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
BRX and 706 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BRX sensitivity is rated at 90 dB and the 706 S2's is at 88 dB. This 2 dB difference makes the GoldenEar BRX a more sensitive speaker compared to B&W 706 S2, 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.
BRX can handle a max power of 250 watts RMS from the amp the whereas 706 S2 has a max power handling value of 120 watts RMS, 130 watts less than the BRX.
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
706 S2 features Binding post posts which make bi-amping or bi-wiring possible. BRX has a 5-way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both BRX and 706 S2 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 GoldenEar BRX's and B&W 706 S2's external dimensions. 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) whereas B&W 706 S2 has external dimensions of 340.0 x 200.0 x 301.0mm ( 13.5-inch x 7.8-inch x 11.-inch) .
B&W 706 S2 is 7mm narrower and 12mm less deeper than GoldenEar BRX but it is also 32mm 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 GoldenEar BRX is approximately 647.9cm2 / 100.4inch2 and base area of the B&W 706 S2 is approximately 602.0cm2 / 93.3inch2. The BRX requires 8% more surface area than the 706 S2 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 GoldenEar BRX weighs 5.45kg / 12lbs and the B&W 706 S2 weighs 8.05kg / 17.7lbs. This makes the 706 S2 48% heavier than the BRX.
Here is a comparison of how BRX and 706 S2's weights compare with the average, max and min weights in Passive Bookshelf class.
