             What size room are the Triangle Borea BR02                and Monitor Audio Bronze 50 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:

         Borea BR02 features a 1" silk  Tweeter  and 1 x 5" fiberglass Woofer  with a Crossover frequency at  2900Hz.  On the other hand, the Bronze 50 features a 1"  Hard-Dome Tweeter  and 1 x 5.25" C-CAM Woofer  with a Crossover frequency at  2500Hz. 
     
    
         Frequency Response
        
            Borea BR02 has a frequency range of   51 - 22k Hz whereas Bronze 50 has a frequency range of 40-30k Hz.  With a minimum frequency of 40Hz, the Bronze 50 can go significantly deeper on the low side and provide stronger bass compared to the Borea BR02's min frequency of 51Hz. 
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
        
            Borea BR02 and  Bronze 50 have the same Impedance of 8 ohms  but where they differ is the sensitivity levels. Borea BR02 sensitivity is rated at  89 dB and the Bronze 50's is at 85 dB.  This 4 dB difference makes the Triangle Borea BR02 a more sensitive speaker compared to Monitor Audio Bronze 50, 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.
                        
            
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
        Bronze 50 features Post posts which make bi-amping or bi-wiring possible. Borea BR02 has a Binding post which doesn't feature bi-amping/bi-wiring.

             Cabinet Type and Port Position
        
            Both Borea BR02 and  Bronze 50 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 Triangle Borea BR02's and Monitor Audio Bronze 50's external dimensions. Triangle Borea BR02 has external dimensions of 310.0 x 176.0 x 274.0mm ( 12.2 x 6.9 x 10.7inch)  whereas Monitor Audio Bronze 50 has external dimensions of 281.0 x 166.0 x 265.0mm ( 11.0 x 6.5 x 10.4inch) .
 Triangle Borea BR02 is clearly the larger of the two speakers. Its body is 10mm wider, 29mm taller and 9mm deeper than Monitor Audio Bronze 50. 
		
			Below you can see the front view size comparison of Triangle Borea BR02 and Monitor Audio Bronze 50 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 Triangle Borea BR02 is approximately 482.2cm2 / 74.7inch2 and          base area of the Monitor Audio Bronze 50 is approximately 439.9cm2 / 68.2inch2.         The Borea BR02 requires 10% more surface area than the Bronze 50 which gives it a small disadvantage on placement in tight spaces.
