Bronze 1 features a 1" Dome Tweeter and 1 x 5.5" C-CAM Woofer with a Crossover frequency at 2700Hz. On the other hand, the Ultra Bookshelf features a 1" aluminum Hard-Dome Tweeter and 1 x 6.5" Composite glass-fiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Bronze 1 has a frequency range of 55-30k Hz whereas Ultra Bookshelf has a frequency range of 45-32k Hz. With a minimum frequency of 45Hz, the Ultra Bookshelf can go significantly deeper on the low side and provide stronger bass compared to the Bronze 1's min frequency of 55Hz.
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.

High Frequency

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
Bronze 1 and Ultra Bookshelf have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Bronze 1 sensitivity is rated at 88 dB and the Ultra Bookshelf's is at 87 dB. This 1 dB difference makes the Monitor Audio Bronze 1 a more sensitive speaker compared to SVS Ultra Bookshelf, 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.
Bronze 1 can handle a max power of 150 watts RMS from the amp the whereas Bronze 1 has a max power handling value of 70 watts RMS , 80 watts less than the Ultra Bookshelf.
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
Ultra Bookshelf features 5-way post posts which make bi-amping or bi-wiring possible. Bronze 1 has a Post which doesn't feature bi-amping/bi-wiring.

SVS Ultra Bookshelf's 5-way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Bronze 1 and Ultra Bookshelf 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 Monitor Audio Bronze 1's and SVS Ultra Bookshelf's external dimensions. Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm ( 10.2 x 6.4 x 8.0inch) whereas SVS Ultra Bookshelf has external dimensions of 380.0 x 218.0 x 281.0mm ( 14-15/16 x 8-9/16 x 11-1/16inch) .
SVS Ultra Bookshelf is clearly the larger of the two speakers. Its body is 53mm wider, 120mm taller and 76mm deeper than Monitor Audio Bronze 1.
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 Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2 and base area of the SVS Ultra Bookshelf is approximately 612.6cm2 / 95.0inch2. The Bronze 1 requires 45% less surface area than the Ultra Bookshelf which gives it a small advantage 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 Monitor Audio Bronze 1 weighs 3.50kg / 7.7lbs and the SVS Ultra Bookshelf weighs 8.64kg / 19lbs. This makes the Ultra Bookshelf 147% heavier than the Bronze 1.
Here is a comparison of how Bronze 1 and Ultra Bookshelf's weights compare with the average, max and min weights in Passive Bookshelf class.
