What size room are the Monitor Audio Bronze 1 and B&W 705 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:

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Bronze 1 and 705 S2 are 2-way speakers.

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 705 S2 features a 1" Solid Body Soft-Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
Bronze 1 has a frequency range of 55-30k Hz whereas 705 S2 has a frequency range of 50-28k Hz. With a minimum frequency of 50Hz, the 705 S2 can go significantly deeper on the low side and provide stronger bass compared to the Bronze 1's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Bronze 1 and 705 S2 have the same Impedance of 8 ohms and their sensitivity is also same at 88 dB.
Sensitivity
Bookshelf Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
705 S2 can handle a max power of 120 watts RMS, whereas Bronze 1 has a max power handling value of 70 watts RMS, 50 watts less than the 705 S2.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
705 S2 features Binding post posts which make bi-amping or bi-wiring possible. Bronze 1 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Bronze 1 and 705 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
The size of a speaker can sometimes be 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 B&W 705 S2'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 B&W 705 S2 has external dimensions of 407.0 x 200.0 x 301.0mm (16-inch x 7.8-inch x 11.9-inch).
B&W 705 S2 is clearly the larger of the two speakers. Its body is 35mm wider, 147mm taller and 96mm deeper than Monitor Audio Bronze 1.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
B&W 705 S2 needs about 78% more floor or shelf area. B&W 705 S2 is 96mm deeper, so it stands that much further out from the wall. B&W 705 S2 is 147mm 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 Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2 and base area of the B&W 705 S2 is approximately 602.0cm2 / 93.3inch2. The Bronze 1 requires 44% less surface area than the 705 S2 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 B&W 705 S2 weighs 9.32kg / 20.5lbs. This makes the 705 S2 166% heavier than the Bronze 1.

These sit in different price classes - B&W 705 S2 costs roughly 11x what Monitor Audio Bronze 1 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | B&W 705 S2 digs deeper - 50Hz against 55Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 88dB) - both want much the same power. |
| Headroom | B | B&W 705 S2 takes more power (120W vs 70W) - more in hand in a big room. |
| Size | depends | Monitor Audio Bronze 1 is easier to place; B&W 705 S2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | B&W 705 S2: bi-amping. Monitor Audio Bronze 1 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | A | Monitor Audio Bronze 1 is cheaper - $299 against $3,299, about 91% less; arguably a different class. |
A Monitor Audio Bronze 1 B B&W 705 S2
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: B&W 705 S2 measures better, Monitor Audio Bronze 1 costs about about 11x the price% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, which makes the cheaper Monitor Audio Bronze 1 much easier to justify. Match it to your room: we rate Monitor Audio Bronze 1 the better fit for near-field listening and a small room, and B&W 705 S2 for a mid-size room and a large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
