What size room are the Wharfedale D320 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:

D320 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer. On the other hand, the 705 S2 features a 1" Solid Body Soft-Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
D320 has a frequency range of 56-20k 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 D320's min frequency of 56Hz.
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
D320 and 705 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D320 sensitivity is rated at 87 dB and the 705 S2's is at 88 dB. This 1 dB difference makes the B&W 705 S2 a more sensitive speaker compared to Wharfedale D320, hence will play louder with the same amount of watts.
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 D320 has a max power handling value of 100 watts RMS, 20 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. D320 has a Post which doesn't feature bi-amping/bi-wiring.
Wharfedale D320's Post terminals
Cabinet Type and Port Position
D320 has a bottom firing port whereas 705 S2 has a rear firing ports. Wharfedale D320's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 705 S2 with its rear-firing port.
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 Wharfedale D320's and B&W 705 S2's external dimensions. Wharfedale D320 has external dimensions of 321.0 x 181.0 x 277.0mm (12-5/8 x 7-1/8 x 10-7/8inch) 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 19mm wider, 86mm taller and 24mm deeper than Wharfedale D320.
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 Wharfedale D320 is approximately 501.4cm2 / 77.7inch2 and base area of the B&W 705 S2 is approximately 602.0cm2 / 93.3inch2. The D320 requires 17% 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 Wharfedale D320 weighs 6.02kg / 13.2lbs and the B&W 705 S2 weighs 9.32kg / 20.5lbs. This makes the 705 S2 55% heavier than the D320.

These sit in different price classes - B&W 705 S2 costs roughly 13.2x what Wharfedale D320 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 56Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (100W vs 120W). |
| Size | depends | Wharfedale D320 is easier to place; B&W 705 S2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | B&W 705 S2: bi-amping. B&W 705 S2 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | Wharfedale D320 is cheaper - $249 against $3,299, about 92% less; arguably a different class. |
A Wharfedale D320 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, Wharfedale D320 costs about about 13.2x 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 56Hz anyway, which makes the cheaper Wharfedale D320 much easier to justify. Match it to your room: we rate Wharfedale D320 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.
